Been thinking about what size tires and wheels go with my turbo Miata.
Well I was happy with 205/50/15's with 190 rear wheel horsepower, but considering the fact that I am wanting to run 260 rwhp, I just don't know how well those will hold up. I been looking at the 6ul 15x8 nickel wheels with 225/45/15's.
Thoughts comments on this? My car is a 10th anniversary with FM generation II springs? Any recommendations on tire and rim sizes that may be better suited for 250-270 rear wheel horsepower?

The problem right now is finding tires in the size. Toyo R1Rs are about all you can get in 225 currently...happens every time the race season starts, because no one wants a tire in that size

I've found some 225/50/15's that are very affordable, but I doubt they will clear without significant rolling and all that bullshit...
Second, this may sound stupid, but can I run a 205/50/15 in the front and a 225/50/15 in the rear.... Kinda like a staggered setup? I if I recall, the only point in running a wider tire than 205 is if high torque is a factor, which is why I don't see why I need such a wide tire on the front.

that's how newbsauce's setup currently stands...
nothing wrong with the R1Rs, they are a great tire, but it's just all you can get right now. I hope you're not looking at ASTs.

We run R1Rs in 195/50R15 in our MaX5 (Spec Miata) Cup. They wear pretty fast with the 120hp we've got. I wouldn't run them on my turbo. We are happy with R888s in 225/45R15 in terms of grip and wear.

We've been running the Kumho XS with great success on our SM car while developing it at DE events. We're getting ready to move tot he R1R, but I'm very impressed with the Kumho for the money...

I've ran 16x7 before, 205/50/16's. I was set on 15x8, but if 15x9's are the way to go, then that is what i'll do...

I think tire design and compound is going to make more of a difference that switching between 205 and 225. I've run hankook tires in 225 and then switched to Kumho XS in 205, and the kumhos were far superior in grip.
running a staggered setup is probably not as big a deal as people would make it out to be, but it would probably throw off the car's balance a little since miatas aren't designed like that.

I recently bought a 2004 stock turbo car with Toyo proxes that need changing. These tires are cupped some on the outer edges and make A LOT of noise. Handling is OK but not my M5. Can / Should I put new OEM Proxes on the car or can I go to a Michelin PS2 205/45/17 that is a .75 taller tire without degrading the performance a lot? I have not seen any postings about anyone using Michelins and they don't make the stock tire size. I have Proxes on my M5 but they don't make this God awful noise. Thanks in advance for your advice.
