Once upon a time, when talking to a rep from the tire industry...Goodyear?? I think...I was told that the majority of those alligators on the side of the road are from truck tires . Was told that most large truck tires are retreads, but that retreads are just as safe as new tires, in fact that the airline industry is almost all retreads.

Don't know if the above is true...just passing on info.
