VE Clubsport Tyre Replacement - Ouch$$$

[Phantom-R8]

Well the smallest of things sometimes end up costing big $. I had the unfortunate luck of getting a screw stuck in one my rear tyres - no big deal, took the wheel off, put the spare on.
Drove down to the local tyre shop to get the hole repaired - probably a $25 job. It seems that driving (even short distances) on a semi-flat 275/35 19 inch wheel does no favours for the tyre. Removing the tyre from the wheel revealed a significant amount of finely shredded rubber that had been worn away from the inside of the tyre - caused by the rim pushing down on the tyre wall.
New tyre - $815.00......damn, that's nearly half the cost of my new exhaust!
Message to all Clubbie and GTS owners - be very, very careful with flat tyres!

$815.00???!!!?!?!?!
I was spewin when i bought a set of tyres for my landcruiser @ around $300.00ea

Not lookin forward to replacing the tyres on my ssv when the time comes. Might be a little bit cheaper than the clubby and gts tho i hope.

Exact same thing happened to us. Lucky my hubby is really really pedantic about our tyres and we found out practically straight away. $17 and it was all fixed.

[APCLB]

Being an pedantical isoteric about ones car does pay off! :p ;)

[planetdavo]

Ultra premium 275 width Bridgestone on the back. It's not a common size (yet), so this is the price of playing in the big league...
People love having tyres the size of Ferrari tyres on their Holden's, so although an HSV might be an eighth of the price of them, you still have to pay those prices!

I think he was just lucky, as I had driven no more than 300 meters on my flat before I realised. I had just pulled out of my driveway & pulled a uturn onto the highway when I noticed something was not quite right. Pulled over checked the wheels & bingo 1 x flat tyre. I was in the R8 which was wearing 18" Pirelli Rosso's. I thought I could just get the nail removed & the hole plugged, but no luck there as I had the same little bits of rubber floating around the inside of the tyre. Short story is that my daughter has a near new Pirelli tyre as a swing in the backyard. Almost makes me cry each time I look at it.

[TLX]

Yep....

We should have known this..........once you buy an R8 or GTS it would be a good idea to buy shares in Pirelli / Bridgestone / Dunlop.:yahoo:

Enjoy,

Less than 3,000 kms hit an object on freeway & holed the sidewall on the front, $690.00 fitted.

Scary bit is at 10,000 kms hard to get good/perfect (according to tyre place) alignment as tyres have developed wear patterns and can't be rotated.

Need a sarcasm smilie here, at this rate going to go through to $3,000 worth of tyres in 6 months:cussing:

[jaykay]

I was thinkin about going 20x9.5 with 275 tyres on the back of my SSV but this causes two issues -

1. The huge cost of the tyres and
2. You can't rotate the front and backs....

Went with 255/35/20 all round at $346 each.... :teach:

What brand of tyre and model of tyre?

[jerrel]

i have 245 on my rear, and 235 on my front. would it be a bad idea to rotate them? they are just regular clubsport vx rims

I cant see why not?? as the other guys with the VE have the dilemma of having different size rims on the front & back, where your rims are the same size front & back it is just the tyres are diff. Just as long as the same tyre size is on the front or back, not 1 of each if you know what I mean.......

Hope this helps,

Belz, that's interesting, cause I got shanked a little while back (in a Maccas carpark no less)... and my regular tyre joint and my service guys were both adamant that any tyre 45 series or smaller cannot be repaired - must be replaced...

I would NEVER put larger tyres on the front than the back, regardless of whether its 235 vs 245.

Thanks for the tip on the tyres, man those prices are scary!, It was mentioned to me by a collegue , and verified by my holden dealer that its reccomended that you take your new pride and joy in for a wheel alignment at around 5000kms, by doing this $40 check it could save you heaps of bucks later, Im taking my E series R8 in tommorrow.

No it's not that interesting, as most tyres of any size can be repaired depending on where the problem is and the condition of the tyre. If it is a sidewall or if it is close to the edge of the shoulder - it can’t be repaired.

Perhaps your tyre guys just aren't that good at communicating.

Well it depends on what damage has been done vsxxgurl. Cause my tyre is on my car repaired... I took it straight to HSV and they fixed it then and there.

Maybe you should consider going else where for your tyres from now on :)

Holy crap - 5000km alignments??? I screamed blue murder when my VT2 SS was chewing the rears off in that space of time (equated to 6 weeks driving). I couldn't go more than 10 000km between wheel alignments or I could kiss $600 worth of tyres goodbye. I thought that had improved in later models - now they seem to be going backwards again!!

[blackbettyhsv]

phantomR8 do yourself a big favor, go and put nitrogin in your tyres. you just reminded me I ran it in my last car, going down today to do this one also. does'nt stop nails or screws but does'nt go down as quick, also you get a bit better ride. sorry about your misfortune but keep thinking about that exhaust, should make you feel better

[Phantom-R8]

phantomR8 do yourself a big favor, go and put nitrogin in your tyres.
Good suggestion - I'll follow-up on that one. Hopefully the new tyre will be on today, I'm tired (no pun intended) of running around slowly on the spare.
The new exhaust is never far from my thoughts, it's just going to be a bit later into 2007 now.

Received my HSV owner's pack recently and noticed it included a pre-delivery wheel alignment report. I guess new suspension will settle a bit in the first 5000km so a follow up check is probably a good idea.
Was interested to note camber was around -1.2 degrees, my VU SS is set at -0.5 degrees. Toe was similar to the ute, didn't have castor measurements.

Are you crazy? That would be close to the silliest and most dangerous piece of advice I have seen posted on here. I know it's well-intentioned but it is so wrong.
Do NOT put bigger tyres on the front compared to the rear. EVER. It is a great way to explore the scenery backwards...:shock:

[macca33]

Mmm, people wonder why I don't mind running 17s still...........

In any event, I would never put anything over 18" on a car that I own. The roads that I contend with are not very low-profile friendly.

As for the wider tyres on the front-end option, I totally agree with Ryzz & Seldo - DON'T DO IT. Aquaplane city.

cheers,

I understand and totally concur with not putting wider tyres on the
front than the rear, but where does aquaplaning come into the equation?
Please explain :)

Dont understand this one, so please explain, the rim size is the same just the tyre is 10mm wider. How does this cause what you are saying is going to happen. I could maybe understand if the rims themselves were different sizes as there is 1 1/2 inches difference between the VE HSV rims. I presumed 10mm would not make your car spin out. If this is the case well I stand corrected & have learned something new,

Do I get a trophy??

If this is the case well I stand corrected & have learned something new,

Let's start with the question ..."Why do we have bigger tyres on the back than the front....???" Say 235/255 which gives a 50/50 balance of grip
Answer: To give better traction on the rear so the car is correctly balanced...
Q: If I put equal sized tyres on the front/back will that change the balance?...
A: yes...if there was say a f/r grip ratio of 50/50 with the previous existing balance of 235/255, by changing to even 245/245 we may end up with a new imbalance of 55/45 f/r...
Q: If I fitted the bigger rears (say 255s) on the front will this change the balance...?
A: Yes - you may end up with a grip imbalance in the order of 60/40 f/r...
like I said - it's a good way to unexpectedly explore the scenery ....Backwards! Don't do it!

[BLACK 346]

A: yes...if there was say a f/r grip ratio of 50/50 with the previous existing balance of 235/255, by changing to even 245/245 we may end up with a new imbalance of 55/45 f/r...

Our cars come standard with 235 all round (well vt-vz do), so
are you saying they are unbalanced?

Cheers Seldo, this gets even more interesting & I was unaware of this,

Just a couple of more questions for you then. So are you saying all of the guys out there with VE HSV's that are changing to aftermarket rims that are the same size x 4, versus original different size front & back that these cars are now unbalanced & will spear off backwards?? How do the other models stay on the road with 4 x same size wheel & tyre combos?? & what about the older model cars that came out with 4 x same size as stock but have now gone aftermarket with different size front & rears, these would also be unbalanced then?

I thought you had larger "rims & tyres" on the rear to help transfer more power to the road due to having more contact with the road surface. I am taking the R8 off to Beaurepairs tomorrow so I will check all this out with them also. I was more talking about a change of 10mm in tyre width, not different rim size by over an inch. I was unaware that a 10mm change in "tyre size" only could cause the car to be uncontrollable.

I thankyou for your wisdom & advice,

[seldo]

Our cars come standard with 235 all round (well vt-vz do), so
are you saying they are unbalanced?
No - Not at all. That is what they are designed for. But VEs that come with a different f/r ratio are designed to maintain that ratio.

[BLACK 346]

No - Not at all. That is what they are designed for. But VEs that come with a different f/r ratio are designed to maintain that ratio.

In a word - maybe Yes. Bear in mind that these "imbalance" things only come into play right at the limit - most times in day-to-day situations you would never notice....until sh1ts are trumps and a situation arises where you need 100% traction in an emergency and you come unstuck. That is where you need everything going your way. It is also where - having come unstuck and pranged, the insurance inspector checks your car parked backwards in the bush and says "..Whoops...this car has the tyres backwards on the f/r ratio. which has clearly contributed to the accident...sorry...claim denied....!" :shock: :)
Be warned!

OK, I have got the answer I required. After speaking to the boys down at Beaurepairs on Saturday I am pleased to say that 10mm difference in tyre tread on the same size rim WILL NOT affect the car if you put the wider 10mm tyres on the front. He looked at me like there was something wrong with my head when I asked him. I did not go into the rest after this since it answered my question, which was, if I put my 10mm wider tyres on the front which were on the back & have the same size rims all round will this cause my car to be uncontrollable or unbalanced & spear backwards off the road?. He answered no, the only thing that may happen is it might rub on the front strut as even a 235 tyre is very close. I did want to clear this up as I got tagged with handing out the worst ever advice in LS1 history in my original post.

Looks like no trophy then?

Sorry mate don't agree with yours or Beaurepairs assesment of the situation.
Seldo was 100% correct you don't put wider tyres on the front of your car period. Whoops I almost made an error if you have a big HP FWD car and wish to drag race it then on a 1/4 mile track it would be suitable.

I have had lots of dodgy advice from tyre joints and TBH I think that some of the staff at these shops will say anything just to get you out of their hair.
If you explained that you would hold them responsible for any screw up that may occur when you ran wider tyres on the front I bet they would back out of their advice very quickly.

I did however have a Tyre company refuse to sell me 2 tyres to run on the front as they were a very soft compound and the rears were hard and I was advised that it was an unsafe combination . They offered to put the soft on the rear or sell me 4 . I bought the 4.

cheers

Thats OK bud you dont have to agree with me, as Beaurepairs advised me. I was not in a bodgy shop & I was also spending more than 2g in tyres on the day, I spoke to the supervisor & manager who both confirmed this. I am sure there are going to be alot of "I know this & I know that, but the question was would it make the car unbalanced & make it spear off backwards if the front tyres were 10mm wider. The reply I got (while they were laughing) was NO. We are talking about A 10mm difference here, not an inch or more which I could understand, but this is all over 10mm only in difference, same size rims just 10mm wider tyre on it. I would presume I would receive correct advice from these guys. But then again.....

Looks like you got hit with the old "cant let you leave here on these tyres because they are unroadworthy & I could lose my job" line. HA HA, you went in to buy 2 tyres & you came out with 4. The sales guy certainly did his job.

Also what about the cars that run slicks on the back for track days??? these are different compound to the front tyres, & the cars are being used to its full capacity. your comment makes no sense.

This is old news now-next thread

[myss427]

I put Brigstone 255 SO3's on the rear of my monaro to help stop the wheel spin, and it was amazing the difference, it made the car twitchy. I have gone back to 235's and the car is more ballanced but you get the wheel spin.

[Lethal27]

After being in the automotive industry for a while you hear lots of stories about what is right or wrong! The fact is Manufacturers spend millions of dollars and years researching the correct tyre & wheel combination for that vehicle. We buy the cars and modify them. Opinions may vary but at the end of the day the only thing that is correct is your placard. Insurance companies no longer ask about wheel fitments. If the wheels fitted to a vehicle are different to the placard - no claim. People need to do more homework on vehicles before they buy them. The most common thing to happen is people buy a $60,000+ HSV and when the tyres wear out they buy cheap rubbish to replace them. Then they wonder why the cars drive like sh#^! Unfortunately for the tyre industry the people with knowledge are retiring and leaving behind uneducated people. :driving:

Just because a tyre place "says" its ok to do it ie they will work on the front doesnt make it legal or safe.

The DOT rules state that the wider tyre/rim combination must be on the driving wheels.. So on the commodore that is rear.

The knowledge of whats right and wrong in the tyre industry no matter where you go is dwindling fast. There are so many things to consider when changing wheel/tyre size it not if it fits is good which is what alot of "well" known places do.

I was sold 255 & 265 types for an old HQ monaro I use to own, 255 was fine 265 was not. The tyre place (a well know one) said yeah she'll be right and it can be fitted without any problems. Not the case.

Beware of what is told to you and do your own research from DOT/RTA and the tyre/car manufactures. Afterall they design the car and tyres so they will know the most about the different combinations.

Nope didn't get hit with that line well I did once about 20 years ago but not since. I am a regular visitor to Tyre Shops for not only my cars but semis and B Doubles as well and 2k would only stretch it too 2 1/2 steer tyres I am afraid.

Hmm not only do you have fatter tyres on the front they are also taller than the tyres on the back. Your car obviously has an incorrect profile fitted maybe someone didn't know that the 245's would be the wrong diameter but just didn't give a shit. 245's are fine all round mate as you will then have the same diameter but your speedo will be out , you allready knew that though didn't you. I am sure the Tyre shop told you .

:lmao::lmao:
1) I am buying for a car not a truck(well thought out comment though :werd:) also over 2g for 4 x passenger car tyres aint too shabby in my books, I could have spent more but with 3 cars, houses, 2 kids, 4 cats, 2 dogs, school fees etc all on 1 income, not to bad (there are better out there I am sure)

2) all my 4 tyres are the same size 235/40/r18 x 4 so have no idea what you are talking about. Just because you go wider does not mean that the rolling diameter has to change, did your tyre shop tell you that also. You can get wider tyres with same diameter eg,235/40 ZR19TL 91Y(1),, 245/40 ZR18TL 88Y so once again I dont understand. The bit about the speedo being out with "larger rolling diameter than stock" is basic though, most should know this already. This does also not apply to me as VX R8 came out stock with 235/40 which is what I have put back on, so no change in width or diameter



3) I am going to listen to a truck driver over a reputable national tyre business? I am not 12 (the 2 guys had 35 years experience between them), a high number of trucks out there on the roads are running around with more than 1 bald tyre, not to mention the mixture of recaps & normal tyres thrown into the mix. But being a truck driver you will already know this...
I was in Logistics as a ops manager for 15 years & I have seen & worked with plenty.

My tyres are all the same size, diameter as stock & my speedo is correct, but thanks for asking & to me they still cost a bit.

You can get wider tyres with same diameter eg,235/40 ZR19TL 91Y(1),, 245/40 ZR18TL 88Y so once again I dont understand. The bit about the speedo being out with "larger rolling diameter than stock" is basic though, most should know this already. This does also not apply to me as VX R8 came out stock with 235/40 which is what I have put back on, so no change in width or diameter




:thumbsup:


OK you stated that the rim size was the same when you started this therefore the 245 tyre is wider and has a larger diameter. Would you please post the specs of the same tyres ie 245x40 is bigger than 235x40.

No need to try and get personal but as you started it we own a lot of real estate ,a couple of them are worth more tha 1 mill each and I could retire tomorrow if I wanted too.

Most of the dumb truckies at work earn more than 100k a year a few topped 125k don't know too many ops managers doing this.

So what are the tyre specs ????

cheers

Never got personel just dont like being talked to like a child.

I listed my tyre size in my post you just quoted, they are 235/40, same as what came out on the car, what is your point here???

Tyre diameter does not change on a 235/40 to a 245/40 the first numbers are the width of the tyres, the 2nd number is the height of the tyres, see how they both have 40, that means same size & also rolling diameter. It is only the width that has changed from 235 to 245 (is this what you mean) or were you just piking up on my typo??

I made enough out of the ops game to set myself up move on to make more cash, I have not been in the game for about 5 years now & yeah more than 125k a year, it all depends on who you are working for I suppose, also never called truckies dumb where did you get that, some of my best mates are truckies. It is common knowledge that so called blue collar workers are from from low income earners, I know brickies labourers who take home more. But this is not about how much we earn it is about tyres & I was correct in saying that over 2g for 4 tyres hurts. Especially when it is being done every 10,000 to 15,000 klms

The difference between 245 and 235 wheel and tyre diameter.

235x40x18" = 645.2mm Diameter
245x40x18" = 653.2mm Diameter


Look you could run the wider and taller ones on the front without "spearing off" into the bush but it isn't done.

If your tyre shop told you that there would be no difference to the rolling diameter I suggest you find a new shop.

My old tyre shop is Beaurepairs ;)

The 2nd number is actually a percentage of the 1st number !! but you allready knew that didn't you ..... you were just seeing if the rest of us knew or not .

I stand corrected

Here are some more interesting facts, I will give you that 4mm diff in ride height, as only half of the 8mm equates to raising the actual car level. It is also legal to put these tyres on as it falls within 3% variance that is accepted. Not only that the speedo would only be affected by 1 maybe 2klms if you were to go a 245 tyre on the back & advice from VIC ROADS was this would pass for registration & roadworthy. They also suggested that as most car manufacturers set their speedos within a 10% tolerance with most speedos under reading speeds by up to 5 or 6klm/h the chances of having to get it changed are slim, but it would have to get checked once tyres have been put on the vehicle to confirm speed reading is within the required tolerance for actaul speed of car so the reading could be deemed legal. Forget the tyre mobs, I went straight to the source of legal requirements. (when buying tyres I have a product in mind then search for the best deal. I have no loyalties to anyone when it comes to spending cash)

But here is where it gets interesting, this only applies to stock level cars, as soon as a car is lowered in any way its aerodynamics change & a whole lot of new numbers come in to play. By putting 245 tyres on the front you are actually raising the height of a car (by 4mm), but if it the suspension has been lowered from stock the car is still lower than original ride height from manufacturer which also means the car is not riding at the recommended height setting for this vehicle.

It actually gets quite in depth & when you think about it most of us at 1 time or another has been driving around in a car with updated bigger rims & lowered suspension, which is exactly what we have been talking about not doing

215/60/16 all round on standard VY Berlina rims. Costs less than $150 per corner for a reputable tyre that lasts about 20,000km on the rear.


Sure, it's no race car, but handles the crappy B Grade NSW roads that I travel on frequently very well.

It's horses for courses - pick the tyre that matches the type of driving you do!

I wouldn't buy a car with tyres that cost 800 bucks a corner to replace, but that's just me. Doesn't mean the GTS isn't an awesome beast.
