Does anybody have suggestions for E load range tires for a Ford SD 250? This truck is road only. The only dirt it sees is the parking lot at MX tracks. I want a tire that will last. It came with General tires ( size 235/85/16) which lasted about 40k. The last set was Uniroyal, which only lasted about 30k! So far, I'm leaning towards the Pep Boys Futura (a Cooper tire I think) for about $500 a set out the door, and it comes with a 60k warrenty, which is pretty unusual in a load range E tire. Dunlop, Firestone, and BF Goodrich tires are about $650-700 out the door, and have no treadwear warrenty. Any other suggestions? Thanks.
