Considering that I drive a 2+ ton truck at over 69.0 mph at most times, I would NEVER ride on a few pounds of tires that I had some doubts about. Tire constructions provide traction, durability, wear, bruise resistance, air retention, fuel economy, handling, emergency maneuvering, stopping distance, balance, load capacity, longevity, speed rating and a safe and secure feeling in the cab. I ONLY buy GDY, MIC, BRI, DUN, COO (thats Cooper: Now a Ford OEM Supplier), UNI, CON, or GEN brands. If you can't afford a set of 4, buy 2 at a time. If these are for the son-in-law you hate, gift these baloney skins to him and tell your daughter to stay away from his truck.
Even junk yards can provide decent tires (2 at a time only) if you look them over.
