I've always heard they were nice, but don't have personal experience with 'em.
A review from tirerack:
"I am the Manager of a Tire store in Vancouver, BC, and decided to put my 2 cents in because I have these on my Xterra. Great tire, I have had them on 7000 miles and checked the tread(BTW you cant check the tread in the middle because there is a platform, you have to check about 2 inches from the center to get an accurate reading) and still have almost 90% left, they are going to go for a while. We have alot of Wet weather here, and I am very confident on these Tires. And they are also Snow Certified...so I dont have to change them for the winter." -- Review Submitted 2004-10-07
