Just took off a set of Goodyear Marathons that had 25,000 miles on them. NEVER had a hint of a problem. Only took them off because of age and mileage. They still looked great. Obviously some wear from 25,000 miles. They saw all day tows in 95 degree heat. Scrabbled over rock strewn National Forest Service roads. It's a fine tire.
