burnout question

[hurricane ss]

Got a question to ask.Why do black tyres produce white smoke when you do a burnout?Think about when you buy a set of coloured tyres ie(blue etc) they produce blue smoke so why then if you smoke up black tyres they dont produce black smoke?

:lmao: After a fairly thorough Google search I came across some funny as f*** answers, including the following;


the tyres absorb matierials from the road surface... oil water crap.. etc...

this is "burned" off the tyre as it spins on the road
the varying proportions of stuff on/in the tyre changes the colour of the "smoke"

oil = blue
water = white


This is probably the most likely that I've come across;


Did somebody call for a chemist?
OK, I can't give you the specific chemistry involved with those reactions, but I can tell you that it involves more than just the degree of combustion. Smoke is a colloid, that means it is a suspension of very fine particles in the air. The colour of a colloid will depend on the size of the particles as well as the chemicals involved. To give an example, we all know that gold is a yellow colour right? Well if you take gold particles suspended in a solvent, and make the particles smaller an smaller, eventually you get a solution of a completely different colour (purple I think- don't hold me to it!). Ok, so the same will apply with the smoke. The smoke will likely involve a mix of chemicals, soot particles, water vapor in some cases, unburnt fuel (either diesel or pieces of rubber depending on which example you are working with). Now the chemicals involved will alter the colour, and the least combusted will be the darker colour, but we can also expect that small particles will produce a lighter coloured smoke than larger particles.
