New 15x8 wheel coming!

[themitchster359]

interesting. that kinda makes sense, why not go with a staggered tires with staggered wheels?

[Massive Lee]

Back in the DTM days when they had e30 M3s, the last year saw M3s with front 18" and rear 19" wheels. The intent was to make the rear tires "stiffer" to help rotate the car.

So, knowing that a 225 tire on 7" will be softer on the shoulder (more compliance and grip) than on an 8" rim (stiffer sidewall, less compliance), the front 7" and rear 8" on the same tires would theorically bring the car away from understeer. But no staggered tires please.

I'd take a set for this years track. is it worth putting 15 x 8 in the rear with 15 x 7 in the front or could you go 15 x 7 all around?

With a non-staggered setup you can rotate.

225's are legal?

no. 205s are. but 225s would fit fine as well. like jgood pointed out, hoho's are generally wider tires.

[JGood]

unless you are required by the rules to run 7" wide wheels, 15x8's would be better.

I've run 225/45/15 hoosiers on both 7" and 8" wheels and they fit much better on the 8's

The section width for 225 hoosiers is 9.8", where it's 9.1"-9.3" for most other r-comps.

you missed the part about 15 x 8 not being spec e30 legal. also i don't think the toyo would bulge as much as the hoho.

[kishg]

why not go wider though? The toyo would still be bulging, and would fit better on an 8

depends on the tire. toyo-r888 225/50/15s would fit perfectly on 15 x 7s

8" wheels would be great with 225 rubber.

It fits, but you'll get more contact patch on an 8". On the 7" it's very pulled in. I used to run 225 710s on 7" wheels before I went to 275s, and I was looking for an 8" wheel. These are light enough that you're definitely better off with the 8".

I can believe it, I ran 225's on a 6.5" and it was pulled in pretty bad.

Now I'm running 205's on an 8 and it's stretched like a dubber :(

15 x 8 is not spec e30 legal..

Oh that, no care about spec e30 ;)

I think it would fit a 7" just fine as Tire Rack measures a 225/50/15 V710 on a 7" rim (range is 6"-8"), so it would be extra weight for no reason.
