FWIW, I ran close to 60K on the Revo 1's with my 97 Blazer. Could have been more, but I traded it in at that point.
Great tires. I didnt do aggressive offroad, but they took me up many a colorado mining road tryin to get to 4x4 only trail heads and campsites. Never once left me strandid.
If I had the cash id buy a set for my 3rd gen today.
