I am on the fence with them. I have bought a few sets of tires there, and always had good service, until the last set. When they installed them, the truck shook, they blamed GM, said I had suspension issues. Took it to Chevy and low and behold, 3 out of 4 were out of round.
Back to America's Tire, video in hand, and they started out with the same story, would not watch the video. Had to get a Manager to watch the video, and he agreed they were out of round, but he said he could not replace them, I had to buy yet another set, and wait for the manufacturer to inspect them. It was his opinion it was a road hazard issue, or something I had done to them.
I went to another dealer, he looked and said there was a bad run of them, and replaced all 4. Not sure if it was a one off or not.
