I had a set of Michelin LTX A/T2 tires on my truck for 50000 miles before they needed replacement. These Firestone Destination AT's have only 35000 miles on them, and I will be replacing them before the snow flies this year. The Firestone tires were highly rated and were $20/tire cheaper, so I went with a set. They never performed as good as the Michelins. I have had to use 4 wheel drive to climb up a hill on a highway that was covered in about 2 of snow because the truck kept breaking loose. I was even passed by a Kia going up that hill, talk about embarrassing. Now it has started to hydroplane in medium rain storms, even though I have approximately 1/2 of the tread left.
I will be going back to the Michelins later this year.
