Should I replace p tires with lt. i tow a travel trailer 1000-1500 miles per year

depends on the weight of the trailer, off the top I would say yes. you probably don't need a 10 ply tire. there are XL rated P metric tires and a LT load range C which is what I have run before.

Insufficient information for definitive reply, however...

Depending on loaded weight of TT and whether a WDH is utilized plus size of your OEM wheels/tires, there are intermediate options to LT E-load range tires. My own choice with then new truck was Toyo Open Country AT2 tires in OEM 18" size, however with a twist compared to other tire manufacturer offerings. Not P-metric but LT C-load range as shown from their catalog listing pasted below.

P275/65R18 BSW (P/N 352070 - 4 ply)
LT275/65R18C BSW (P/N 352500 - 6 ply)
LT275/65R18C OWL (P/N 352510 - 6 ply)
LT275/65R18E BSW (P/N 352480 - 10 ply)
LT275/65R18E OWL (P/N 352490 - 10 ply)

You can see 'em (P/N 352500) on mine in this related thread post.

Sorry, 275/65R18. The ride might be harsh, but no rear end sway when towing. Last set of tires were rated for 100,000kms but they are done at 70,000kms

I tow a 5500 lb travel trailer with my ecoboost, i replaced the stock Goodyear because they felt squishy when loaded even had psi up to 42. I was going to replace with lt tires but was convinced by tire shop to try the p rated Michelin LTX, that made a huge difference truck rode much better felt firmer I ride around with 38 psi all the time no need to adjust and ride isn't harsh at all.

^^^ Well then, my suggestion would apply to yours. These tires are a popular choice on this forum, however usually larger sizes in combo with lift than the catalog numbers I selected. My truck has only rolled 7.3k miles since new with just prox 6.8k miles on those Toyo tires, so I can't factually say how long useful life might be. Regardless, several members of local jeep club use them on weekly rocky AZ trail runs without failures known by me. I prefer GY MT/R with Kevlar sidewalls for my own jeep trail rig, although wouldn't consider same tire type for my truck...

Fsdogs. That is the tire that only lasted less than 3/4 of its rating. They are so squishy right now, it's dangerous.

No, because you'll max out your truck's GCWR long before you max out your tires. The only thing a LT tire will do for you is give a stiffer ride and lower fuel economy and less towing performance due to weight.

Sorry to hear that, I've had great success with mine and are wearing very well. Good luck
