Rated 5 out of 5 by from Great winter tire Live in the Keweenaw Peninsula of UP of Michigan. Get at least almost 300 inches of snow in the winter. I just have a FWD SUV and it outperforms AWD's. For example going up this one icy hill and I got up it without trouble even passed two AWD SUV's that got stuck on the hill.

Rated 5 out of 5 by from Best Winter Tire I've Owned I live in Canada and have driven a pickup truck for most of my driving years. I used to be very attached to the BF Goodrich TA All Terrain tires and used them year round. They are an amazing tire and, if I had to choose just one tire for year-round wear, I may still go with them, but there really is no substitute for good summer and winter tires. I've run these tires for two winters now and just put them back on for a third. I expect to see at least two more winters out of them before I wear them for a summer to burn them right out. I'll get 100,000K out of them for sure before I have to buy more...and I will definitely buy these again. Anybody looking for a good WINTER tire should look into these. If you want an all terrain, I wouldn't suggest these as they wear a little worse in warm weather. Thanks Cooper, you make a great piece of rubber.

Rated 5 out of 5 by from Impressed with these tires I kind of thought these were a lower quality tire when I first purchased them but I've got to say they have held up quite well. I had a set of these of my 4Runner for the past 4 winters now and never had an issue. I had them studded and was really happy with the traction. I can drive down a dirt road covered in a foot of snow without needing to use my 4wd. I love that feeling of having superior traction in really bad weather.

Rated 1 out of 5 by from Tires won’t last. I purchased these tires had them studded and they performed well all winter. I had them changed out for my summer tires with just over 11000km on these tires. Two of the tires were wore pretty severe in the centre and two tires had normal wear. I had run these tires at the pressure recommended on the door of the truck. 39lbs. Cooper is denying warranty as they claim they should have been run at 35lbs and they were over inflated. Winter tires are softer and will not last as long but I have never experienced this type of wear with a properly inflated tire.

Rated 5 out of 5 by from 2nd set, best snow tire ever... I owned a set back when they were made by Dean tires, called a WinterCat SST and they were great then. Now, Cooper makes them and they are the same great tire. Work fantastic when studded up. I will buy again.
