I don't
have to install the TPM sensors but I'm going to. Anything worth doing... This winter set should last a good 3 years since I'll be able to rotate them properly (same width front and rear) and the wheels I'm getting aren't bad looking. Next spring I'll be left with the decision of whether to buy new tires for the stock wheels or to upgrade like I really want and have 3 sets of wheels and tires, 2 of them with summer-only rubber.
If I were in the States I would sell the stock wheels. Apparently the wheels I got aren't the same as the normal US market 135 M-sport wheels. That or BMW is using a different wheel for 2012 models. At this point I only have a few message board threads to go off of.
Pay to play, pay to play...
