Have a 2009 E92 w/19"s. Had original PS2s on it when bought in Feb '12 with 22k; car now has 29k. Put new Michelin PSS on all four corners within last 1,000 miles.
Car tracks straight, does not pull. I have no evidence of any previous alignments.
I have a coupon from my dealer for a four wheel alignment for $99. I trust their service department, they have previously looked after my E91 and E90 328i.
So far, advice I have gotten is that it's not necessary, but I am inclined to spend the $99 at this point to get a baseline, especially with four new tires.
