Any issue to run 285/40/18 on 18*10.5 et25

[tonywham]

Still researching about the 18" wheels. Hard to find a set of wheels with right offset. Not sure if I can run 265/40/18 on 18*9.5 et22, and 285/40/18 on 18*10.5 et 25. Will there be any rubbing issues by running these on M3 with ZCP (not lowered). I think 265/35/18 and 285/35/18 will be better, but it gonna make about 3.7% difference with the original overall diameter, not sure if an alignment is need or not. or there will be other problems other than speed variance.

Which tires? Shouldn't be any issue unless they're extremely wide r-comps.

I'm damn close to pulling the trigger on a set of 275/40-18 R-S4s... 75% chance they fit, 25% chance they'll rub the fender liner on turns by my measurements. (Which should be fixable with a little heat gun massaging if I'm looking right)

Change wheels won't require an alignment, but if you can get more neg camber that would be good...

Edit- however those rears at et25 may be problematic... I'm looking 11s around et40-44

Anyway, all about the brand and tread width up front. We're close enough that it's going to come down to the details...

275/40/18 shouldn't be a problem. 285/40/18 is a problem:

I would rather go with 285/35/18 than 275/40/18...anyway, from the picture, it looks really nice... so it's really rubbing?

Yes, this is the only angle of the rear that I took, but it's poking out about 4mm even with pretty aggressive camber
