um..they last a good while..I kinda F'ed up my first set.. IE bad ball joints so the camber was out just enough to cup the tires. then trying to achevie a perfect ride I lowered the fronts down to 35psi which made them ride good but played hell on the tires. I also went with a long haul tire(told it was the best for smoothness) it was smooth..but its not made for city driving or a 'high scrub" application like turning and stuff. I was thinking the this entire time that I was gonna get 100K out of the tires so i did burnouts and stuff..soooo..thats what happened to the rears.
I replaced them with the Michilien XZE they are for 'high scrub' applications. All my ball joints are new and the front end is aligned properly. Also Im not letting the PSI down that low again. So needless to say, These tires will last till I sell it. I got approx.70K out of them.
I have a fabtech 3.5" hanger kit in the front. Truck rides fine. Its all in the tire and somones ability to balance them.
Some may last 100K..mine didnt, but some of that was my fault.
