terra grapplers!!!!!! Mine on the diesel hook nice but they get destroyed (they dont spin but they leave lots of tread on the ground)! my fronts look brand new my backs are balled they have 12k miles on them. My f-350 has them aswell ive put 50k miles on the truck since January and they have loads of tread left. So unless your putting over 1k rwtq to the ground there a great tire lol
