As I stated, I have more than 34K miles on these tires which are just on the rear of my Colorado 2 wheel drive. Tread life has been very good, even on just rain covered roads, but these tires have got me through two very bad snow storms here in Saint Louis. The last one was just about two weeks ago and I was going back home during the early morning hours before the plows had a chance to hit the pavement. These tires just dug into the snow and got me up two of the steepest hills we have in our area that are Interstate roads. Some cars were just stuck half way up the hills, where I was just going right along. I was worried at first, before the storm had hit that I had already worn thru the compound that gives me the traction in the snow, but these tires just kept me going. Firestone has my back with these tires, I just hope they don't discontinue making them and at the price that The Tire Rack sells them for, it is a win, win situation for me. I plan on buying another pair to put on the rear of my truck and move the ones that are on the rear to the front, that is how much tread I have left on these tires!
