I had 12.5 x38's on my old 85 (no pics) LOVED THEM, good on the road for what they were... Awesome every where else. Had them for about 2 years and they still had good tread when I sold the truck. But that was about 15 years ago, maybe a different compound used today......I had some 12.5 X 35 LTB's on the current Toy, they didn't last a year.....
