Okay, we're waiting on our new travel trailer to be delivered. It's larger (longer / heavier) than our current trailer. I've been considering an upgrade to 'better' tires, but I'm not sure it's needed, or, what I actually have on the truck now. What I mean is that I've read a lot about 'P' tires on F150s, but I don't think that's what I have on mine. My OEM tires are Goodyear Wrangler, LT, Load range 'C' tires. I have a 2012 F150 Screw, 3.5 Eco with max tow.

Are these the 'P' rated tires everyone talks about?
(sorry for the dumb question)

Max cold psi is 50. Door jam says inflate to 35 psi, but when I tow, I air up the back to 44 psi. Works fine for me with my current trailer (5500 lbs or so loaded, 24 ft overall length).

Our new trailer is 5900 lbs dry, 7600 gross, with a tongue weight of 740 lbs. (obviously could be more when loaded). The trailer is a Sunset Trail Grand Reserve, SS26SI, overall length is 30 ft.

No, you have light truck tires...load range C. You are fine .Some people have E rated and some C rated LT tires..C should ride better than E. I think it has to do with the side wall's.

With that heavy of a trailer, I would suggest max pressure.

No. P-series tires are for passenger cars and the lighter-duty half ton pickups, vans and SUVs. The P stands for "passenger car", although they are standard on most F-150s. My standard tires on my 2012 F-150 Lariat are size P265/60R18.


LT tires are for heavier-duty pickups and vans, including Ford SuperDuty trucks and a few heavy-duty half-ton F-150s. LT stands for "light truck". Factory-installed tires for your 2012 F-150 with the optional off-road and XLT chrome packages are size LT275/65R18C.

Another point to consider, though the LT C may give you a little stiffer side wall; I'm not sure. It has a lower load index of 113 or 2535# carrying capcity per tire at max psi of 50. A P metric of the same size at max psi of 44 is rated at 114 load index or 2601# carrying capacity per tire

A P rated tire is rated for more weight than a "C" rated LT tire. The "C" rated tire will possibly have a tougher sidewall for off-road driving where rocks are in contact with the sidewall. But won't help at all with towing or payload.

The C rated LT tires are designed for light 4X4 vehicles like Wranglers for off road use, not towing. A "P" series tire will carry more weight than a 1/2 ton truck is rated for. If I felt the need for a tougher tire I'd skip straight to an "E" rated tire.
