While I don't have any direct experience with retreads, there's a reason for that. Tires are the most crucial part of a vehicle. So everytime I've been shopping for tires and have come across retread pricing I have asked myself, is saving $300 worth the risk? Most good offroading tires will last over 40k miles with proper alignment, inflation and maintenance. So that $300 in savings isn't really all that much when you consider savings/year or savings/mile. Thus, I always choose to stick with proven/known brands. Regardless of how many sucess stories I hear, its just not worth the unknown risk.

With that said, if I was building a trailerd trail rig.... I'd toss retreads on that in a heartbeat.
