*20inch Wheels On a VX HSV*

[Sonnymad]

Guys ,


I have been looking round for a while now at 20inch wheels for my hsv,though i cant come across a honest answer,do 20's fitted with 245/35/20 touch the guards ? as i dont want to roll my guards ,i found these wheels i really love ,they are called "Ellanor" by B-BOSS Wheels,they assure me they wont touch,can anybody shed some light on this ? as i really want those wheels...

lol i would have thought u are the man to ask. u no all the answers.

lol i would have thought u are the man to ask. u no all the answers.

It's know not no :stick:

I had 20 inch HP Design Rims on my VX SS at one stage, car has not been lowered and I had not had the guards rolled. The back only scrubed out when I had a full car load and went over pumps, but by my-self and two other people it was fine. The size tyres I had on mine Sonny were 225/35ZR20 90W if that's any help, I know its slimmer tyre but I seriously had a inch clearance from tyre to back guard when it was parked in the front lawn. I was seriously thinking about getting it lowered half an inch with out the guards being rolled :lol:

Sonny i had 20s on my VZ clubbie with 245x35x20 with kings superlows and it would rub only slightly where the rear bottom skirt came around to meet the rear wheel arch. You do need to roll gaurds as it will rub. I sold my 20s after 4 weeks as they gave me the shits from rubbing and being harsh. Was ok on the front cause i could adjust the coil overs to a set height.

You can get away without rubbing on the rears if the offset on the wheels was correct and if the suspension wasnt that low.

235x35x20s would be ideal and would not rub but there hard to find.

This is my experience on my car.

Jim,

These rims are specifically made for a commodore so the offset is correct for a commodore,i dont want to fit the 225's as they look terrible,as the rim sticks out further then the tyre,i would prefer 245's or 235's ,as i dont wanna hack my car up to fit rims,anyone else have feedback on 20's ?

regards sonny

Sonny the 20s in my pic are specifically for commodore and they still scrubbed out. The 680mm overall diameter of the tyre is big so if you could get it to 670mm you would be ok and a 235x35x20 would do that. I think nittos come in the 235 size and yeah the 225 are to small. The only areas mine scrubbed on was the arch at the gaurd where the bumper attaches where the 2 screws hold it on and thats because of the sheer size of 680mm tyre diameter.

Definately go 235 if you get 20s.

[scotty]

What happened to the 19s that were getting resprayed?

Does this mean they are available?

Do I need to call your wife !!! 4 sets of wheels is enough man :slap:

Repeat after me ... " My name is Scotty and I'm a wheelaholic ... it's been 1 week since I bought my last set " :lmao:

[V28VX37]

Sonny,

pretty sure 245/35R20s will not fit without mods. Most of the stories seem to go like "mine never scrub except at full load/full lock/..." etc.

Having just changed from 235/40R18 (Firestone) to 235/35R19 (Yokohama) I'd recommend against 20s at least if you drive much in the metro area. Avoiding potholes is fun for only so long, and the ride is getting almost too firm at least for my taste.

Btw your choice of wheel is tops :) You can get the same 10 spoke design without mirror finish and black inside paint as "DTM Grange" too.

Cheers

[GETUTED]

I'm sure one of your connections would let u trail fit a pair of 20's to see before you sheel out the $ But in my opion it WILL scrape without rolling the guards.

I would have thought that too! A man of Sonny's standing should be able to give things a trial run before committing.

*Boink* DTM Grange in 20"...they fit with a 225 tyre but when lowered there's a bee's dick clearance both on the inside and outside of the wheel without coil overs....

[hotbox]

With 20'' wheels take everyones advise with a grain of salt. i bought a set of 20s with 245/35/20s and ended up changing the tyres over for 225s. Best bet would be try before you buy. from memory best offset is 46p.

[Vulture]

Whilst the grange and Clubby look superb in those pics, I long ago decided that 19" wheels were the biggest practical size on the VT-VZ series. Just being able to bung on a set of 19"s with 245 tyres is too easy to ignore. Maybe a 9 or 9.5" rim on the rear too (with rolled guard). Depending on the design they still look pretty big IMO. There are quite a few stories of people going back to 19s from 20s as Jim has.

[Maz]

245/35 20inch tyres will not fit on the front as the tyre is too high and hits the bottom of the strut. Need coilovers for these to fit blown the budget right out.

225/35 and 235/35 tyres fits on the front as its not quite as high however the load rating is too low for a commodore, instant defect right there. The wanli 225/35 tyre is the only tyre load rated high enough in this size. Wanli tyres have a hard compound so they last long but provide very little traction. The thin tyres also look shithouse on an 8.5inch wide rim.

Bridgestone Potenza RE 050 in 20inch are not available in Australia but would be worth importing. They are the only 20inch legal tyre in the entire world for commodores. They are 245/30 with a load rating of 95. That means they have the same rolling diameter as a stock HSV 19inch tyre and load rating to fit all commodore models. These tyres are very high performance definitely the best option.

The last option is to fit a 255/30 tyre such as sticky Nankang NS2. The stock struts actually have more space available width wise than coilovers. Coilovers allow for a higher tyre only. 255/30 tyres are a perfect fit to an 20x8.5 rim, you cannot fit a 255/30 Nankang on a 20x8, i tried. The only problem with this option is you may require a very thin spacer on the front depending on the wheel offset, im talking 1mm maybe 2mm thick spacer very thin. I test fitted an 8.5inch rim with a 255/30 tyre and it fit perfect without spacers, however the rims i wanted ended up only being 8inch wide. If your car is at ultralow height you will run into clearance problems with the guards, however if the car is at "low" or "superlow then rolling the guards front and back will be all thats needed.

So the best option is to go the Bridgestone RE 050 tyres if the rims are 8inch, if not go 255/30 Nankangs if the rims are 8.5inch as they provide exceptional traction.

The other options i would not consider for a high powered car. Running a thin tyre will be illegal and/or provide very poor traction. 245/35 tyres with coilovers are also technically illegal as well as the rolling diameter has increased by more than an inch over standard.

[vytwo]

Sonny, if you fit 20s without rolling your guards it WILL rub if the car is lowered at all unless you go to 225 tyres...which look shit (and it may still rub)

Nitto 555r is one of the few 235/35 20 tyres on the market, they are a quality tyre at around $350 a corner.

Most manufacturers make a 245/35/20 tyre.

[IH84DS]

Sonny,

I was out shopping around for 20's for my VT, every honest tyre shop I went to said the same thing. "You can't legally fit 20's on commodores, they don't make 20inch tyres that meet the load rating required by holden".

Now having said this, some would say "who cares", I do just for the fact that if I get into an acco, insurance won't cover it. Now I value my car and hope that insurance will pay me out if something goes wrong.

I'm not saying u guys should go and take ur rims off, just thought I'd let you all know cause it came as a shock when I was told. So I just bought a set of 19's.

Regards,

George

Have to agree with you there,but thats why i'm insured with shannons,even despite the issue's with 20's,i,m gonna purcahse the wheels and give them a go,if i dont like the fitment or they touch i will sell them,at least i know i gave it a shot,as my cars preety much std height,if anything it might be like 1/2.inch lower,thanks for all the replys ;)

I think they are full of sh!t - the new VE GTS has some sort of Bridgestone245/30 R20's stock standard and aren't 20's an option on other Holdens/HSV's ?

[Maz]

Did everyone miss my post?

The rolling diameter of the VE is more than an inch larger than the earlier models.

The VE runs a 245/40 19inch tyre, where as previous models use to run 245/35 19inch tyres. A 245/40 tyre has a much higher load rating than a 245/35 tyre.

The only tyre that is 100% legal in every way are the Bridgestone Potenza RE 050. It will come to about $500 per tyre once imported, a very high end tyre though. 245/30 with a load rating of 95, thats the same rating as a 245/35 tyre but smaller.

just thought id throw this in (working for an insurance company and all) when we write new policies, the diameter of the tyre means nothing. its the width that is deemed as risk.

oh and sonny, i put 245/35/19's on and i had to roll the guards with standard FE2 because it was scrubbing around corners.

[Vulture]

the diameter of the tyre means nothing. its the width that is deemed as risk.

Forgive me for being a tad suspicious but does that mean you insure cars that are unroadworthy as I am led to believe that the diameter is important in terms of roadworthiness?

[vyssls1]

Sonny,

if the 20's scrub a little, on the front eg spoon drains, just adjust up the camber on the front eo give yourself a little more clearance, as there is enough room in the front to the normal strut to achieve 2 degrees negative.

mind u camber will wear the tyres a little, but the toe is the most critical for tyre wear.

The rears shouldnt scrape at all.

Good luck in the decision Sonny, i hope they fit.

These days wheels are the hardest decision i reckon to make, wheels either make or break a car.

Cheers

Sonny show pics when done, and give some feedback.

[Sonnymad]

Thanks again guys for the helpful answers,i,m hoping they dont scrub as like i said my cars basically std apart from being 1/2inch lower,will post up some pics for sure,still thinkin bout the tyres though,gonna have to do more research,also if anyone else has anything to add would be great to hear ur experience with 20's :D

regards sonny

[notsostock]

I have been chasing 20's for my WH caprice for about 2 months now, have talked to just about every tyre shop in the country (seems that way) and have had a myriad of different answers. Don't know how this will apply to a VX HSV but here are the results of my research.(mine are being fitted on wednesday so there may be updates):yahoo:

CHECK YOUR TYRE PLACARD. I can send you an excel sheet that has a calculator on it if you anyone wants as you must be within the rolling diametre by no more than 15 mm either way to be legal. as far as i was told it doesn't matter what was available on the vehicle it must be relevant to your tyre placard.

For this reason i was limited to a few sizes, namely 245/30's 235/30's (not sure if the even exist) or 225/35's.

I was told 245/30's will foul the shocks however coil overs ($2000???) are not required. New shock towers are available which raise the cradle that the coil sits in enough for the tyre to clear. i would expect that guard rolling would be required to fit them as well.

Another option i looked into was 235/35's which were to big (rolling diametre) by 2 mm, but had an adequate load rating for the car. found them at Ozzy Tyres for $400 a corner, or i was going to have to import them.

225/35's is what i ended up with as they fit legally however as mentioned in an earlier post aren't readily available apart from Wanli S-1099's which have a load rating of 93W. I have seen 225'35's on 20's and am aware they are narrow but would much prefer to be legal.

[BEWARE]

I've had 2 sets of 20s on my ute now, the 2nd set are perfect, its amazing what a small amount of an offset difference will make!

My first 20x8.5 with 245/35/20 tyres and a 42 offset, scrubbed on full lock, rubbed on the top lip of the guards over bumps(guards are rolled) and the rears rubbed under WOT and on the plastic liners. Now the new Billets are again 20x8.5 the same 245/35/20 tyres but a 45 offset, I've been able to wind the front coilovers down another 6 turns from the last 20s and it doesn't scrub at all, never over bumps, not on full lock....NEVER....smae with rears, even with about 120kgs in the back, under WOT...NOTHING....I'm planning to get my rear springs reset to the height the car sits at with that 120kg load!!!!

Its all in the offset.....3mm made a MASSIVE difference to the drivablity of my car!

[HRT 8]

I've had 2 sets of 20s on my ute now, the 2nd set are perfect, its amazing what a small amount of an offset difference will make! BINGO. Not a truer word spoken. Most peopledont even know what offset is, let alone what it needs to be for a specific vehicle.

Id say that answers your question Sonny.
Coilovers are a must. Utes as you know tend to be more restrictive in the arse end in terms of scrubbing etc than sedan, sou should be good to go as long as the wheels your looking at are.
20x 8.5 with a 45 offset running 245 section tyres.
And for christ sake dont put shitty little 225 section tyres on. Esp the Wanli's.
If you wnat to know why I say this about Wanli's then a quick search using my name and wanli will reveal all. (im too lazy to type the story out.)

[motionSS]

thats kewl m8, im not sure what the reasoning behind this (dont know alot about underwriting yet) but i can tell you for 100% sure when we go through underwriting Q's that the diameter EG. 19" 20" etc. does not even come into it. as for roadworthines, at the time of a claim if the car is deemed unroadworthy then you get nothing if your at fault. but we dont ask about diameter we only ask for width.

i think he means the overall diameter of the tyre... as in the rolling diameter. because if you breach it a certain percentage each way your car becomes "unroadworthy"

Can people stop filling this thread with bullshit and incorrect answers.

Incorrect, the 245/30 20inch fits perfectly. Its the same width and rolling diameter as a stock 245/35 19 inch tyre. Only one tyre the Bridgestone Potenza RE 050 is load rated in the 245/30 size, everything else is well under.


225/35's is what i ended up with as they fit legally however as mentioned in an earlier post aren't readily available apart from Wanli S-1099's which have a load rating of 93W. I have seen 225'35's on 20's and am aware they are narrow but would much prefer to be legal.
Like i said the 225/35 wanli is the only tyre that is legal and available in Australia. Im running this tyre too, its ok for a v6. The wanli is a hard compound so it lasts a long time but has average traction. Soft compounds dont last long but have excellent traction, its a compromise between tyre life and traction. I do not recomend the Wanli tyres go with one of the other options.


Its all in the offset.....3mm made a MASSIVE difference to the drivablity of my car!
Completely bullshit, you have coilovers. With stock struts you could have the wheels sticking 2inchs out of the guard the tyre will still hit on the strut due to the rolling diameter being too large. Offset means nothing with stock struts!!

You do not need coilovers to fit 20inch rims. You can fit:

225/35 wanlis
255/30 nankangs.
245/30 potenza's

or even 235/35 tyres will fit but the rolling diameter is too big and not all of the tyres in this size have a load rating high enough. 245/35 also has a rolling diameter that is much to big.

If you go coilovers you have LESS clearance on the side wall of the tyre compared to the standard strut, but coilovers give plenty of height above the tyre allowing you to increase the rolling diameter. You will not be able to easily fit 255 wide tyres with coilovers, where as 255 wide tyres can fit under stock struts as i have fit them.

People have to stop listening to the rumours and third hand evidence and listen to the people who have actually fit 20inch rims. Only very few tyre places have actually fit 20inch rims to cars. The tyre places that have go the safe option by fitting narrow 225/35 tyres which pretty much bolt on perfectly. If you are forced to go 225/35 at the front then fit some 255/30 tyres on the rear such as nankangs, atleast that way you will have good traction.

You can also fit crewmen struts on the car. They sit the spring 1inch higher so allows 245/35 tyres to fit with extra room to spare. Only problem is these shocks are designed for 1inch higher than a standard commodore height. So if you have superlows the shocks will be ****ed in no time. Thats why i dont reccomend this option.

Sort of close....If you reworded that to say "In the instance you have cheap shitter coilovers" then you would be right :)
I run V8 Brute race series Bilsteins in the front of my Clubby, and it will still clear a 265 tyre on the front with 3.5 degrees neg camber on an 18 inch rim. Measuring it up 19s 20s all would be ok, but we want to run race rubber, not chrome bling, so 18 is the go.... However you use a cheap shitter coilover and any decent 245 will flog a hole through the sidewall and let go :(
With suspension in these cars, you play, you pay :teach:
No bullshit :lol:

[VooDoo]

LOL Maz, you havent learn't a thing have you. These ppl arent just posting for the hell of it. They have personally done these things, OWNED the cars and products and know what they are talking about. Just because you have some bling wheels on a V6 VT wagon doesnt make you an expert.

Oki Guys,

After the great information i got from some forum members here i ended up gettin 20inch wheels for my sv300,i spoke to daniel from BBOSS WHEELS over the last 2 weeks and i basically told him wat i wanted and did not want,and i certainley did not want to roll / cut or modify my car in anyway to fit a set of wheels and also did not want my car to ride like it has concrete tyres,after several reassurances and back and forth call to daniel,i put my trust in daniel and ordered the wheels i wanted.Daniel sent them all fitted with the tyres and balanced from melb,they arrived the next day and were wrapped very nicley,so off i went home and fitted them,they fitted like a glove,absoloutly no touching wat so ever not even on full lock,and it rides abosoloutly no diff to my 19's,as to say i,m very happy as i got wat i wanted and i wanna say a big thanks to daniel from BBOS WHEELS for putting up with me for 2 weeks asking silly question...perfect service !

Ps: i will have better pics next few days as i have had some pro shits taken today :yup:

Obviously you missed the information from me....

Check the load rating on your Toyo tyres. Toyo lists the 225/35/20 as a 90 load rated tyre, the lowest rating on a VT-VY sedan is 92.

Your wheels are defectable and your insurance is void.

8.5'' rims look stupid with 225s on them. nice choice of rim though.

On topic: Sonny, how's the ride on the 20's in a VX? Also, how's the road noise? I recall quite clearly that even the 18's on a VX Signature and the 19's on a VYII Signature were really loud in regards to road noise.

Edit: Thought I'd add some of the pics for you :yup:


There is no road noise at all and it rides exactly the same as my 19's,i was supprised as i expected some harschness,but theres none.

It my look nice but how will it and you look when one gives.Load limits are there for a reason. :bawl:

Yeah when I looked into this, load ratings on 225's on rims that are designed to run 245's are going to cause problems with insurance. You would not be covered, as its illegal (car isn't road worthy)...

Not sure what laws are like down there but I have known of a few cases here where insurance claims haven't been paid out cause of improper tyres used on on larger rims, mostly on imports though... 225's do fit without any need to roll guards etc :p and they do look great mate... Just check with ur laws their Sonny, hate to see insurance pricks get a reason to not pay ya out if something happens, or for some wank to crash into u and ur put at fault for as ur car isn't road worthy....

Yea insurance is the big one.

I've checked the laws and in every state the tyres Sonny has is illegal and his insurance is now void.

I'd be pretty pissed at the guy that sold you the rims as he knows they are illegal.


Like i said the 225/35 wanli is the only tyre that is legal and available in Australia.

There is a reason why people run the Wanli 225/35 tyres, they have a load rating of 93.

I run out of fingers counting the number of people i know who have been done for load rating on their tyres. Ive been checked 5 times now without any trouble as im one of the few people with legal 20inch tyres. The cops that checked my car just assumed that all 20inch rims were illegal as i was the first car they saw with correctly load rated tyres.

Also 225 tyres look stretched on a 8.5inch wide rim, to me they still look too narrow on an 8inch wide rim i guess. If your rims are 8.5inch wide you should have gone with 255/30 rubbers and rolled the guards to suit.


LOL Maz, you havent learn't a thing have you. These ppl arent just posting for the hell of it. They have personally done these things, OWNED the cars and products and know what they are talking about. Just because you have some bling wheels on a V6 VT wagon doesnt make you an expert.
Looks like they didn't know what they are talking about :lol:

[Satansfist]

Yeah but he can drive his tomorrow if he wants to :stick: :lol:...

Now why would you say something like that Rob? That's just plain evil to rub it in...:bawl: Besides, there's always the lawn mower.:bravo:

[Gatecrasher]

Satansfist - I notice that your rims are more silver looking than Sonny's... are they actually that, or is it just the light/angle the photo was taken?

[chops]

New wheels look awesome and really compliment the car.
HEAPS better than the other things you had on it, I feel they detracted from the car rather than enhanced it.

Now why would you say something like that Rob? That's just plain evil to rub it in...:bawl: Besides, there's always the lawn mower.:bravo:
That lawn mower actually looks a whole heap of fun. :bounce: Get to modding it!! :D

[Satansfist]

Satansfist - I notice that your rims are more silver looking than Sonny's... are they actually that, or is it just the light/angle the photo was taken?


Could be a combination of both. I think Sonny's may be a shadow chrome or something similar (not sure, best to ask the man himself) but definitely have a polished look to the surface whereas mine are called "hyper-silver" they are also DTM wheels as opposed to BBOSS...whatever difference that makes...

[hotbox]

Nice wheels. what offset are they Satanfist or Sonny?

[BEWARE]

Yea insurance is the big one.

I've checked the laws and in every state the tyres Sonny has is illegal and his insurance is now void.

See the thing about that is, if your involved in an accident, assuming its not a major one, you drive home and you put the standard wheels back on for when the insurance assessor comes to have a look. IF you are involved in something major, then it may be harder to do, but you are more than likely injured aswell, so you might have other things on your mind!!!

can I ask what size rim (XX by X) and what size tyre your car came factory with?

[Satansfist]

Mine are standard Holden offset.:yup:

[Maz]

can I ask what size rim (XX by X) and what size tyre your car came factory with?
Im well aware of every rule in the book.

16x7inch from the factory with 225 wide 93 is the lowest rating on the placard.

Im now running 20x8inch with 225/35 93 rated.

As you can only go 1inch wider, my rims pass this first rule being 8inch wide. HSV's and SS's can go up to 9inch wide rims as they come standard with 8inch wide rims.

Rim diameter increase is not relevent providing:
1) The rolling diameter of the tyre does not increase by more than 15mm.
2) The tyres are greater than the lowest load rating.

People with 245/35 and 235/35 20inch tyres all fail the first rule, the rolling diameter increases too much.

People with 225/35 pass the first rule but fail the second rule UNLESS they run wanli's, as they are the only 225/35 with a rating high enough.

People with 245/30 tyres pass the first rule, but fail the second rule UNLESS they run Bridgestone Potenza in this size but they are not available in Australia.

Sedans require a slightly lower load rating of 92. So it allows 255/30 tyres to fit. Usually these are rated at 92, so pass. Rolling diameter also pass.

Only problem is 255 wide tyres is difficult to fit at the front and require other mods such as coilovers and the inner lip of the guard folded up. Also the rims have to be 8.5inch wide, a 255/30 tyre will not fit on an 20x8inch rim i tried.

Also a 255 wide tyre is illegal on an 8inch wide rim if the profile of the tyre is the less 45. So the rims must be over 8.5inch or greater, this is not checked by police as they dont know the rim width. This is a different legislation though and not always checked.

The cops ALWAYS check load rating of the tyres. Ive seen dozens of cars defected for this in Melbourne, and i've heard of insurance not paying out because of the loading rating as well.

What ever you do, dont let VOODOO read this thread, he always gets on his high horse saying how 20inch rims are illegal.

Usually i dont care, but it was the fact that i was ignored and told i was incorrect. I felt the need to rub it in that i was right :)

[SS Sportswagon]

Nice wheels mate i looked at these when i was looking for 20s what is the measurement from the centre of the wheel to the guard front and rear yours looks lower than mine thats all i want to go a little lower at the front and does your rears hit where the rear bar screws to the body Cheers

[BEWARE]

ok but what I fail to understand is how you are saying the Wanli 225 is the only 20in tyre with a correct load rating and is the only one that can be legal...however on a HSV or SS that comes factory with 235 tyre, you can't legally backstep in size to a 225....so therefore they aren't legal either!?!?!?!? As far as I'm aware the only 20in tyre that can be legally put on an HSV or SS that came factory with a 235 is a 255/30 Yokohama tyre, and at $600 or so each and with many other mods needed, people just don't want to bother and would rather trun the risk I guess!!!!






Nice wheels by the way Sonny, glad you decided to go with them....10/10, I love them!!!!

There is no rule saying you cant go with a narrower tyre than standard.

The rim width cannot be altered by more than an inch, which restricted the maximum and minimum widths. This stop extremely wide or narrow tyres from being fitted for safety reasons.

Most commodores come with 225 wide tyres or less.

The only reason 245 tyres are fitted on HSV is for load rating only, as the 235 is not high enough so they fitted the widest tyre they can legally fit being 245's.

Also the 255/30 Yokohama's have the same load rating as most other 255/30 tyres such as Nankangs, Pirelli, Dunlop etc All of these are legal on sedans however because they require effort to fit as well as an 8.5inch rim no one bothers doing it properly.

255/30 Nankangs NS2's would be the way to go and considering Sonny already has coilovers they should have fit up easily with only the inner lip being folded up, so from the outside it would look identicle.

Plus the 255 wont be stretched over the rim "drift style" like in those photo's.

This thread should be made a sticky, as it now has alot of technical information.

[BEWARE]

My mate who manages a tyre shop has never offered me a 255 Nangkang, he has only said he can order a 255 Yoki in.....are you 100% positive you can get a cheapie 255/30 with the right load rating????

Are you also 100% positive that you could legally backstep a size in width to a 225/35/20 when your car came stock with a 235???????

Do you work in a tyre shop, or have you just learnt about all this info for your own sakes?

[Covert]

Are you also 100% positive that you could legally backstep a size in width to a 225/35/20 when your car came stock with a 235???????


You need to be cautious when checking legalities of modifications with regards to different requirements for each state. Obviously Maz has correctly said that there is no restriction on decreasing tyre width in Victoria but you would need to check for your state. NSW is the same in that there is no restriction on reducing tyre width. There are rim width constraints, which in a practical effect also limit the tyre width variation.

[BEWARE]

hmmm yeah I get your point, I just can't see how it would be legal, ADR obviously specifies that a certain vehicle must have a 235 tyre for saftey reasons, I can't see how it could be legal to put a smaller tyre on a car which would in effect make it less safe by having less contact with the road.

But it doesn't matter anyway for me, my 20s are being sent to Canberra tomorrow as I sold them after being defected for having too large a rolling diameter....my width and load rating were fine, always one thing thats going to be wrong I guess....and the cop told me I couldn't go backwards from what was specified on my placard, so no 225's, no 245's cos they are too high and no 255s cos they require too much extra work...so no 20s!

What i said applied to NSW, QLD, Canberra and i beleive NT and Tasmania as well. Same laws as victoria.

There are tyre legislations that limit the size for a given rim width and profile. This tyre legislation is for every state in Australia. This in conjunction with the rim width constraint of each state gives you the maximum and minimum tyre width. This happens to be the same for NSW, Victoria and Queensland.

Also when they say "model or series" this means all models of that shape with the same suspension package.

Someone i know who was defected with 20inch rims that were actually perfectly fine according to the "model and series" he got the defect cleared no worries. The guy doing the roadworthy even suggested to change the tyre placard to one that suits in the same "model and series". This is just so the police dont get it wrong in the future, fudging the rules a bit, however this is just making it easier for the police to understand instead of arguing with them.

A tyre that is 1cm narrower is fine just as a tyre 1cm wider. Providing both tyres are designed to carry the weight of the vehicle its fine. Most narrow tyres aren't load rated height enough so again this stops people from going too narrow, in conjunction with rim width constriants.

South Australia and W.A have the "2inch" rule and i cant find any facts that back it u, so this doesn't apply to them. They also ignore the "same model or series" rule.

BEWARE hopefully Sonny doesn't suffer the same fate as you and get defected. The cops are really cracking down on this atm.

[Funky_Munky]

Those pricks. Cant let us have our fun. :vpo:

[dyno junkie]

Maz you stated that HSV use 245's (I presume 245/35/19's), however I recently looked at the GTO Signature and was surprised to see it fitted with 234/35/19's!

[Vulture]

Those pricks. Cant let us have our fun. :vpo:

Maybe it has a bit to do with safety as well?:1peek:

[Funky_Munky]

Maybe it has a bit to do with safety as well?:1peek:

Yeah, good point.

It just gives me the sh*ts that they are the first ones to defect you as soon as you come out of your driveway, but the last to help when a crime has been committed against you.

My car and garage have been broken into 3 times - a total of about $7K worth of loss - and everytime the police advised me there is pretty much nothing they can do, even told me it would be a waste of time to dust for prints.

Anyways, at the end of the day, I guess they have a job to do and they are doing it.

[OLS108]

oh My ,sonny the wheels make an awesome thing just so Much better...:bravo:
can anyone say it just keeps getting Better ?:yup:
