First, I absolutely love my Dmax/Ally (2006 Chevy LBZ LT3). However, in regard to spinning tires, I go through tires like crazy as I am unloaded most of the time. There is so much torque and the rear is so light that it is a lot of stress on the rears (not to mention it rides pretty rough unloaded when offroad or in the curves). My last set of BFG AT KOs lasted all of 22k miles and they were gone. Running Duratracs right now and we'll see how well they hold up. At 58k miles on the odo (owned it since new), this is my 4th set of tires and no, I am not a rough driver or a speed freak by any stretch. That said though, that is my only complaint about the truck. I love it and it is paid for.
