Has anyone tried these on a truck? They get great review at Tirerack and I can get them installed locally for $465 out the door. I am thinking about putting them on a 00 Silverado Reg cab with long bed. This truck will be used for work sometimes towing a 3,000 lb load. I don't know much about tires and I have not been able to find out if these are LT or passenger tires at 255/70/16. I like the price and the reviews a whole lot. Any opinions?
