I should stick this in the classifieds, but I have 4 Michelin Pilot Alpin 225/55/16 snow tires for sale - two of them were previously used on an M5, are an earlier version from the other two, and have a slightly different tread pattern. Approx 7/32 on the older 2, 10/32 on the newer two (which I bought trying to make a set). I think these are an appropriate fit for 2nd gen. 7's, usable for other models w/ 16". $160 plus shipping, tires probably weigh 21-22 lbs/ea.
