I wouldn't pull a 5th wheel with P tires on the truck.

Next time you head out, fuel up and weigh your rig fully loaded. See how close you are (axle weights) to the tire ratings.

What in the world is Toyota doing putting "P" tires on this truck in the first place?

Not sure why any truck that comes with a "heavy duty towing package" wouldnt have LT tires as part of that package.

I switched to LTs years ago. The difference towing with them was a big improvement.

I would go to a LT "C" rated tire. this would be a nice upgrade from your current P tires. I wouldn`t go to a "D" or "E" rated because your 1/2 ton axle rating would be nowhere near needing them.

Please note that if you change to LT tires DO NOT exceed recomended wheel pressures when inflating

For the tires that come in both a D and an E rating the people driving the E rated tires are getting 25-30% more miles per set of tires. I would expect that is you have a heavy load in your truck much of the time that the D rated tires are going to flex more and scrub themselves to death as you drive and you are likely to be disappointed with the tread wear experience. The 10 Ply E rated tires that I have been looking at are on average 25-30% more expensive than the P rated ones so in terms of cost per mile it is about the same.

My truck manufacture'sr specs call for P tires on my truck.

A friend, who doesn't really tow much, said I definitely should use LT tires.

Am I O.K. towing with P tires?


OK? Probably.
But I wouldn't do it. IMO, TRUCKS should have Light Truck (LT) tires.
Also, IMO, the tires should be real traction tires, for best safety.
But, it is your truck, not mine, do it your way.
