I got over 80,000 on a set of Michelins. My 2003 still had the original BFG's on it when I sold it at 60,000, I think they are going to make 80,000 as well. I put a set of Dayton 235/85-16s on my 1993, and a set of off brand 255/85-16s on my 91 this time, they look like BFGs anyway. I had a hard time finding the 255s. Who would have ever thought that size tire would ever be hard to find? Glen
