The only negative about those tires is they affected my fuel economy, My Chevy truck MPG dropped down to that of the Toyota truck.
My parents were up this weekend and my father was looking over my tires, he knows when I get new ones I keep the old for him to use on the farm. I put them on at 30k and now have 115k on my truck and they still have plenty of tread left so it may still be anther year or two before he gets them.
But I can drive up snow covered mountains in WV in 2wd watching other 4x4 and AWD vehicles spinning and slipping.
