I've driven 57,000 miles on these tires in just about 3.5 years on my 2001 Jeep Grand Cherokee. I didn't notice any significant tread wear. I'm glad I came here to read reviews and tire ratings before purchasing these tires. They are a little noisy, but that's a combination of the tires and the age of my vehicle with the lack of soundproofing in the cab I'm sure. Also, I have them balanced and rotated (free of charge) every 6-8K miles and alignment if necessary as part of the dealer/installation agreement. They are amazing in the snow/ice and rain. Best tires I've had for sure. Hoping to get another 50K out of these tires. Miles on my Jeep, 160K. Excellent Tires, will be buying for my wife's new Jeep Liberty as well.
