Hey, I've got these on my E60 AWD as the winter setup and I love them.

The only gripe - if it can even be called that - the sidewalls tend to flex under hard, near-limit cornering. Personally, to me that is a big deterrent, but that's why I only use these for the winter/wet weather setup. Also, keep in mind: this flexing I'm talking about is at the very limit of handling of a very capable sport sedan platform (E60) - X5/X6 drivers may never reach that limit at all.

Anyway, I love these tires and recommend them to everyone, and I know quite a few people who also have these - never one complaint. Definitely a great tire. I've had mine since about a year ago and they are showing barely any signs of wear, which would be in line with their wear rating (which is very high).
