Never had a problem with P rated tires and a 750 pound tongue weight. They key to towing with P rated tires is to inflate them to MAXIMUM PRESSURE. Remember, most half-tons come OEM with P tires. And those same tires are considered when taking all tow specs in to consideration for that particular truck. Most weekend towers use their half tons for everyday drivers and the weekend comes and they do not increase the pressure when hooking up the family camper.
CKNSLS, is correct! There are may times when the P rated tire actually has a higher load rating than the LT tire in the same size. I run a P rated tire on both of my lifted Jeeps and they ride so much better than a LT tire. Obviously, I run a LT Load E range on our Dodge Cummins. I think there is a reason why RV manufacturers use ST tires on many of their trailers. The ST tire probably handles better and rides better than a LT tire.
