At first the dealer recommended that I use the 17" rim or even a 16" rim from the 540i with a Blizzak snow tire. Neither rim would fit over the M5 brake calipers, which are rather large. I have to be able to get around in snow conditions this year, and do not know what to do. Do those M2s really work? I wonder why the dealer did not think of that solution and whether I will be able to find the in the NYC area.Originally posted by Ossi:
Definitely works. I use 235/40/18 (recommended size) and it's really good. I don't know is it wise to use different tire size for back tires at winter. At least here Finland I wouldn't use it. M2 is excellent tire and better than anything I tried. Compared to 17" tires I see a big difference.
