I bought two sets of Treadwright tires over the past 10 years, after doing extensive research both times. People who own and use them mostly agree that they are durable, quality tires with great customer service. Very few stories of failed TR tires or poor service. I found lots of non-owners ranting about the retreads their dad bought in the 1970's, million-mile semi truck retreads, and other straw-man arguments.
Treadwrights are highly regarded in the Jeep community. When I bought the TR's, I was doing a lot of off-road work and little highway driving. The TR's made a lot of sense especially considering the price. I have installed them on a 99 Ranger 4x4, the other a 2003 SuperCrew 4x4.
Tires for the Supercrew were just over $500 for a set of 285/70/17 Wardens - on sale. Another $80 to have them mounted/balanced at Big-O. You can choose casings, so I opt'ed for BFG AT T/A load range 'D' casings. They looked almost identical to BFG's but half the cost. They handled exactly the same as the real-deal BFG's that were on before.
I had one tire (285/70/17 D-load range Warden) split along the center of tread, at about 20k miles. A 4in split that was maybe 1/8" wide. Noticed it when I was rotating tires. I sent them a photo and they immediately sent me a new tire at no charge. It was still drivable and holding air so I continued to drive on it and monitored it for any changes, while waiting for the replacement (arrived 3 days later). They said no need to send the old one back. I kept it for a full-size spare to replace my 10-yr old, too-small spare.
The tires still had 25-30% tread after 4 years and 50k miles when I sold the truck. No funny wear and very little weathering. Felt like I got my money's worth on that set.
