I purchased this set of tires over 5 years ago, and I can't seem to wear them out. I had some front end work done to the blazer early when the tires were fairly new that attempted to wear them more on the outside, but now that the alignment problem has been corrected, and by carefully rotating, they are nearly worn back straight again. In spite of this, the tires have 60K on them and 30-40% tread left. In deep snow, I can STILL hit the go pedal, and be rewarded with my head being pulled back in the seat, and 4 rooster tails of snow flying off the edges of the tires! With 170K on the odo of this blazer, they may actually outlast the vehicle. Best purchase I ever made!
