Around here nothing bigger than a 275/15 or a 28 X10.5 non W, a 325 will put you in big tire. Then there is the 235, 26 X 8 class, we don't see many here though.
Same here. I run a 295-65 radial and there are a lot of classes my car doesn't fit b/c of the tire. I'd put a 275-60 on my car if it didn't look ridiculously small. It hooks fine on the smaller tire, just looks stupid to me.
Even a lot of the street car classes won't allow anything bigger than a 275 or 28x10.5, which I think makes no sense. Like my 295-65 makes it a pro mod or something?
Occasionally you'll see a class specifically for cars on a 295 or 29.5x10.5 slick, but they are few and far between.
There are SOOO many options for a 275-60 or 28x10.5 tire car that I'd be hard pressed to set up a car for anything else.
