I'm at 15,500 miles 7,000 with the 21" staggered Michelin P2's. My alignment is at factory specs, (we are an authorized repair facility and it checked ourselves). The tires are wearing about 25% faster than my '09 Acura SH AWD TL which has the Michelin Super Sports only 19". It looks like the fronts will go to 11 or 12,000 the rears are down to 3/32nd's on the inside now. Driving is mixed mostly city, some freway and mostly short distances. Seems fairly normal for these tires, just more wear on the inside rears. When getting an alignment it's always good to get a printout of the before and after measurements.
