I've been running Nokian Vatiivas, (LR C) since November '06. I'm very impressed with them. Very nice on dry and wet pavement. Excellent snow and ice traction.

My prior tires were Michelin LTX ATs (also LR C). They were good initially but seemed to harden up as the years went by. That's probably why I got 180,000 miles out of the set of 5 tires over 6 years. At the end, any amount of moisture on the road became dangerous, even though there was still 1/4" tread depth left.
