OMG! that looks great! Can you please tell me what size tires you're running on the front, and what width and offset on the wheels both front and rear?

I live outside the US, so I can't afford to make a mistake ordering the wheels. I need meaty tires because the roads here a full of potholes, plus I like that look better than the rubber band look.

The wheels are 18x9 24mm offset front and 18x10 45mm offset rear.
The tires are 255/45/18 front, 315/35/18 rear.

Thanks!

WOW!! That looks awesome. I was also wondering what kind of lowering springs you were using? And have you run more than one set of tires on that wheel with no problems? Alot of people say that the 315 on a 10inch wide wheel is a bad idea. Again your stance is amazing and any input on your experience with this size tire would be extremely helpful.

Killer stance on that car.

Those are Saleens right? The offset for those 18x9 is 36mm, not 24mm.

Unofficially I'll stop a bit short of calling it a bad idea and call it not really recommendable. IOW, I would never recommend it under any normal circumstances.

A 315 is designed to work on a wheel that's 11" wide, and they give you a little leeway either way. The mfr (I think the TRA, actually) recommends at least 10.5" wide wheels.

Mainly, the issues are sidewall flexing and heat generation, and it's not a "pass-fail" thing (where 10.5 = pass, anything less = fail). Expect a 315/35 installation 10's to run a little warmer than on 10.5 or 11, and understand that in allowing that you do give up a little of the mfr's intended margin against bad things happening as a result. Some, but not all of that margin.

I do understand that these are DR's, and that their intended use doesn't really include things like hard cornering or carrying heavy loads long distances on hot days. However, their load capacity is designated "LL", for "Light Load", so anybody running these should keep loading vs tire capacity in mind (load vs capacity is the other big factor where tire carcass temperatures are concerned).

DR's and autocross "R-compounds" have this in common - they're really race tires with just enough tread and other legal stuff to earn them DOT approval. Make your competition runs on them or put your car on display at a show with them, and swap back to your true street tires before you go home. It isn't smart to run them (and heat-cycle all the good grip out of them with tread still left) on the street. Just not illegal if you do.

So what is the best offset for 18x10?

Norm Peterson

Probably +42 or +43. Should work without any rubbing up front or stick out past the flares in the rear with up to 275/40 tires.
