I have them on my e53 (second set) and will switch to them on the e70 when its tires are done. I find them quieter and longer-lived than the Michelins which it is currently wearing, and less expensive up front. I do use the all-season aspect - in fact they have given me excellent traction in very deep (16") snow here. I get 15k-20k out of them, driving pretty aggressively on narrow, winding roads. I would expect 30k in city/highway driving with a gentler foot. I also change them before the wear bars are flush because I need good rain/wet traction most of the year. Without that, they would easily exceed 20k miles even in my driving style.
