Can't really report on the snow handling capabilities of the PA2 yet, haven't had to drive in snow yet; it seemed to handle freezing rain/slush pretty well, however, on the initial drive up to Tahoe.
it is nice Rial Como on X1. where do you get the BMW center caps? are they stickers? I checked with Tirerack, they do not have BMW center for Rial Como due to different size. I believe Como is 64 mm.
