-Michelin Pilot Alpin PA4 245/40/18 square. My local Discount Tire ordered these in for me at $27 each less than Tire Rack as well as $120 in rebates.
These tires mount up great to 18x8 with no perceivable bulge due to a straight sidewall (which I was worried about). The offset is perfect for the front, but another 5-10mm out would be better for the rear. It still looks good though but certainly not as flush as my 275s on ZCPs. I figured if these were the BMW winter wheel (270M) specs, then they should be fine.
The wheels look fantastic and came with pictured center caps and //M stickers. Unfortunately at 65mph+ there is some minor vibration and I'm hoping it's a fixable tire balance issue. I just put them on today, but I'll be taking them back for balance check this week. EDIT: Stupidly realized the center bore is 74.1. Ordering hub centric rings for 72.6...
Initial thoughts on the PA4 since no one has used them yet, they're quiet, more comfortable than my 19" Super Sports, and though early, wet traction seems very promising.
