LT tires vs P-Metric for towing?

I know this has probably been asked and answered many times.... I'm towing a 37' Lacrosse with a soon to be 2019 F150. Trying to decide whether LT tirres or P-Metirc provide better handling while towing. Looking for less sway. Yes, I have an Equal-i-zer hitch, and I don't want comments on the weight of the trailer and that I should be driving a F250.... Heard all that already. It does just fine, but would like to reduce the sway on the highway.

Wow thats a big unit for a 150 i know you don't want to hear it but if it does just fine then why ask? seems you need a Hensley $3000.00 hitch or you will die

I had a similar size TT with my F150 and the LTs helped, but not nearly enough, went to a 3/4 ton.

I am confused, you say a soon to be F150 and it does well with the trailer. If you don't have the truck how can you know? Good luck.

LT tires will tow much nicer but your ride quality when driving the truck empty will suffer.

For that size of TT, NO way would I tow it with Pmetric tires.
I tow with a F150 EcoBoost. So I'll just say, Good Luck to you.

Base on what your towing you should go with LT rated tires load E range..replacing my P-rated tires that came with my 2011 f150 EB is the best decision i made..towing are 5th wheel rockwood greatly improve the handling

LT tires, LRD or LRE would be best. Avoid aggressive tread for more contact area and less squirm. Don't grease anything on the hitch. Increased friction results in less sway. You'll likely have porpoising- Airbags with stiffer rear shocks- I prefer the Rancho RS9000XL on the highest setting-will solve that.

I picked up on that, too. Confusing... Apparently it does not do well as you have sway.

My interpretation is that he is towing with an F150 (undisclosed model year), and he is purchasing a 2019 F150. So the truck/trailer combo is the same, just that he is upgrading to a new truck (of the same model). I could be wrong, but thats how I read it.

You air them up to tow, then let some air out to drive without towing... not that big a deal about ride quality...

that could be but I would expect he would already know if he needs LT tires then. If this is the case hopefully the comparison goes beyond F150 as some may be ok and some may be dangerous.

LT definitely. I changed when I bought a larger TT. The mileage suffered a bit, as did the ride, but when towing felt more stable.

I run 10 ply E rated St tires on the trailer and E rated LT tires on the truck. LT tires, due to the sidewall configuration were not designed for trailers.

Sounds like you already know what's best for your needs. If you're not worried about the weight on your f150 why would you be worried about the weight on p tires.

Tires

Check the load ratings on your 2019's tires sidewall, after weighing truck and trailer. If they will not carry the weight, get LT tires that will carry the needed load. It will help w/ sway, not eliminate it w/ the tow combination. I tried all that on a similar set-up, same WDH, Timburon, Bilstein 5100 shocks, and sway bar. Only feel it w/ high wind on the highway or big trucks w/ a shorter, lighter trailer. Have 4500 mile trip planned, moving to 1 ton to have the capacity go to a 5 th. wheel next year, and envoy the drive more.

I had LT load range E tires and went back to P tires. Best decision Ive made. My rig handles much better with the ps. I do have a Hensley though. My P tires have over 2500 lbs per tire of load capacity when at max psi, when am I I ever going to be over that? The es obviously gave more load capacity, but their meant for big heavy duty trucks. I do run load range Es on my trailer though.
