Tire size differences.. my R888s are wider

[MrQuick]

what ever it is, its "great".

Actually some tire brands can be wider than other brands even though they are the same sizes. For instance, I wanted to get 315/35/17 tires for my 17x11 wheels, and I found out that Goodyear F1, D3 are wider than the Sumitomos 315/35/17. I had to order the Sumitomos because the Goodyear F1s will have more rubbing issues than the Sumitomos..

It wouldn't of helped with these racing compounds but Tirerack.com has all the specs on every tire. Even though the specs vary from manufacturer to manufacturer it sure could make a difference on these custom builds.

There can be quite a large variance between actual tire dimensions between various brand and models of tires.

I remember vividly having 3 different types of P245/50R16 R-compound tires for my 5.0L Mustang race car back in the early 90s sitting in my garage. And they were all different sizes, you could see it standing 6 feet away from them. Not just width, but height as well.
