2nd Chance Camaro - Let the Project Begin

The sidewall height of the tire is more determined by the Profile or series of the tire and 265/40 would give you a better proportion that you wanted.

To do the math it goes like this
265 mm x .35 = 92.75 mm sidewall
295 mm x .35 = 103.25 mm sidewall
275 mm x .35 = 96.25 mm sidewall

but a 265/40 would be 265 mm x .4 = 106mm

So if you are maxed out on width go to a taller profile in the front then the rear. The profile number is just a percentage to the bigger the difference in width from front to rear the bigger the profile change needs to be. It is a pet peeve of mine to not have the same profile unless you trying for a big a little tire combo. If we were running a 335 rear tire and a 275 front tire the math would look like this.

335 mm x .30 = 100.5
275 mm x .35 = 96.25
275 mm x .40 = 110.00
or
285 mm x .35 = 99.75

Hopefully this info is slightly helpful. I have to work up tire combos all the time and it can be tough to get a perfect matched set as far as profile, compound, width and matching tread pattern.

Cool Maverick

Your welcome - glad I can help

Great Info Rodger - Thank you

and your right that is a bad ars Maverick

Of course you would - your car has a ba gillion HP and you need a tire like that. However I think yours is bigger

Huh.....I thought it was a Vega.



Marty,

Your camaro will look cool with either width. Use the narrower ones for going to the mountain-bike trails, and the wider tires for showing your car, like at Columbus!

I agree I really like the 295 but the current trend is the 335 or 345 or even the new 405. But you know me I am not a trendy person. I am still wearing blue jeans and a T-Shirt every day

The 405 only come in a 24". Pirelli makes them. The dually truck guys are converting the rear two tires to one with a 24x15 rim. Looks sweet on a big dually too. There is a guy running the 405/25/24 on a new Camaro....google it. Pirelli also makes a 375/20/21, but the sidewall is so short it looks no wider than a 345 per other forums I read.
