On my 545I I'm running style 172 with 245/40/19 and 245/35/19. Now I'm thinking of changing rims to 20inch miro 111.
So will 245/35/20 and 285/30/20 fit without no rubbing or any sort of problems.

I'm not sure but I vaguely recall a thread asking about this same issue. I think it will rub. Aren't the rears on a 20" 111 9.5"?

Yea they are but I think style 172 rear is 9.5 too

The thing is, first of all, BMW's spec seem to max the rims out at 19". In order to maintain the same rolling diameter as OEM 17", 18", or 19", you would need to run 20" using 245/30/20F and 275/25/20R. However, most people like a little extra meat for rim protection and so the ride won't be so harsh so they end up using 245/35/20F and 275/30/20R which is slightly oversized already. I'm running 275/30/20 rear and I already have a slight rubbing. I'm guessing 285 could be pushing it a bit. However, it could depend on the Miro's offset so who knows?

What other rims that offer concave are decent?
