"P" tire designation vs. "LT"

I bought a new Ram 1500 in 2011 that came with Goodyear Wrangler HP tires. The tires are P275/60R20 and I have only 15k miles on them. My question has to do with the "P" designation which I understand stands for passenger car tire size.

I tow an older 25' Komfort TT that is definatly not in the lite catigory. It's not the perfect match for my truck but so far I haven't had a problem but I am worried that I might be pushing things with these tires. I hate to switch them out sinse they are low mileage and it would cost near a grand to replace with "LT" tires.

Ideally, I would like to wear them out a bit before purchasing LT tires but I want to be as safe as possible and not take unessary risks while on the road towing. I inflate them to the max tire pressure of 44 lbs. before hitting the road with the TT. They are rated at 2601 lbs at 44 psi. Any thoughts?

    I would not change the tires until they are worn out. Then, there are no LT tires in your stock size. I would stick with lighter, P tires in your stock size going forward, until you can replace the whole truck.
    Why? Is there a reason to replace the whole truck...:? I guess I am old school and thrifty, in that he has a truck that is designed to do the job and P metric XL tires that will air up to 55# are available, so why would he replace the truck..? I guess some folks think every thing is throw away, in today's world.

    I'm not a GM guy. If anything, I prefer Ford. Had two F150s and wanted a 3rd. Wife wanted 3 rows of seats and the Expedition wasn't going to cut it. If Ford had the Ecoboost in the Expy, then I'd have one. Buying GM helps my bottom line, so feel free to do so!

    Why replace the whole truck? It's a heavy trailer probably exceeding the receiver rating, payload, and maybe rear axle ratings. The 2009+ Ram 1500's have some very low payloads. Disposable truck? No. But not the right tool for the job IMO.
