Everybody recommends 18" square setup with narrow Blizzaks. But in tirerack.com when I choose M3, it only gives me the option of WS60 with 18"s, not LM60s, and I'm guessing it's too much for Boston and I heard those tires are not good on dry. I need a complete solution, but BMW's ridiculous almost $4000 solution is just a waste.
