Hello everyone!

I'm trying to vet a winter wheel and tire setup for my car on order. I will be running the staggered 19" 792M in summer and want to downsize to square 18s with slightly larger width (235 vs. 225) for improved traction and benefit from a taller sidewall for winter compared to stock. I'm new to the whole offset concept and I'd heard that only some 18" as a result work on the M340i because of the brakes. My configuration is a BSM RWD without the ZTK package.

I've found this combo of BBS XR and Pirelli Sotozero 3, and ran a simulation versus stock 18" 790M (225/45/18 ET25) through this site:

Here's the specifics:

BBS XR, 18x8 ET28
Pirelli Sottozero 3, 235/45/18 94V with Self-Sealing

On-car BBS XR pics on a BMW hard to find in the wild, but the design is very similar to the BBS CH-R, here's a view:



The wheels seem very similar fitment-wise to the BBS SR I've seen a few posters with, just the offset seems to be different (SR is ET30, XR is ET28).

Also curious what the community has to say about self-sealing tires, the cost difference is negligible and they seem to have none of the drawbacks of runflats, just are very rare. Seems like an ideal feature for a winter tire.

Appreciate your insights!
