When considering the grand selection of far from stock offset/width wheels for a Miata and S2000, I wonder why not for a Mini?

15X9 +36 TRM C3M will be my next rim of choice if I keep my Miata. It's a far way from 15X6 +40.

But it would be nice if you offered that variety of fitments for Mini's, including 15-17" rim sizes.

 

If you know of a wheel that tirerack carries you can ask for the width and size of what you want for any car. They may or may not have it in stock with the offset you want or they can special order it for you.

I don't think they want to list every possible wheel that is non standard but rather offer the normal sizes which are most popular along with the tire size that closely matches OEM.

For racing purposes you can take more liberty with what may fit whether tire or wheel size.

Also what might fit with stock suspension may not fit with lowered suspension and big brake kits can reduce clearance, etc. There are so many variables to list all wheels.

 

Tire Rack is just covering their butts when it comes to fitment. You can't really blame them. They have most wheels though you just have to call and ask or send them an email.
