I bought a set of new with paper tags, P265-75R16's at an auction with overstock tires. When I got home, I realized that they are not LT tires. Since I bought them at auction, they are not returnable. Can I run them on my F350 with 7.3L? I do not use the truck to haul anything heavy and do not pull any trailers. The most weight I may carry in the bed would be 2-3 hundred pounds if that.
