I purchased a vehicle with these tires already mounted on it that had a total mileage of 45,000 kilometers and was four years old (the vehicle had been outfitted with them from the factory). On all four tires, I immediately saw that the remainder of the tread was "fat," but the look left a lot to be desired (tread peeling, cracks apparent in some areas). Nobody knows how the car was driven or what the tire pressure was like when they were using it. (Since the representative was unable to purchase the vehicle in the south, they are unable to raise the issue of improper storage (the vehicle had tires that were "from birth" on it). I went to Amazon to read some reviews out of pure curiosity, and while I was there, I noticed a picture that looked familiar. It showed a tread that was breaking apart. As a consequence of this, I decided to purchase a set of tires from a different manufacturer before the trip so that I wouldn't have to wait until the tires completely fell apart.
