I think that LT tires are a must, preferably highway duty and not all terrain. I have Cooper HTs and the sidewall stiffness alone results in a better towing experience.
Trailer is upwards of 7500# fully loaded and I run the tires at 50psi when towing, 40 unloaded.

The link above explain the tire load rating as it correlate to inflation. Most P tires achieve full tire load rating at 35psi. Most LT tire achieve full tire load rating at 80psi. If you inflate your LT tires to 50psi you are only getting less load rating from your LT tires. That is like having 1 ton tow vehicle to tow 5000# trailer, it is over kill.

I don't agree, having towed with both P and LT tires inflated correctly for the axle rating of my 1500 truck, the LT tires provide a much better ride with far less sidewall flexing.
I am speaking with experience backing me up towing both a 7500# travel trailer and 5000# car hauler for thousands of highway miles.
If your experience contradicts mine, fine, bit simply referring to weight ratings is not the whole story.

My truck is atypical from most 1/2 ton models. My 2014 F150 has the Max Tow AND HD Payload Package. It came with OEM BF Goodrich LT 245/75R17 LRE Rugged Trail TA's. The yellow sticker for the tires calls for 55# psi for the front tires, and 60# psi for the rears. My rear axle is 4800#.
When I have to replace the OEM tires, I will replace with a similar tire.

A LT tire load range C tire with a max psi usually around 50 psi will be significantly stiffer than a P rated passenger tire at 35-40 psi. A load range E LT tire with a max 80 psi is even stiffer. The rigidity of these tires comes not only from inflation pressures but from the sidewall thickness ie.. 2 ply vs 6 ply vs 10 ply This means that even at less than maximum inflation, (say for instance the 55-60 psi that Ford recommends for Atlee) these LT tires offer much better performance for towing than a P rated tire, even though the P rated tire may be capable of supporting the load it will have much more flex due to less rigid sidewalls.
Sidewall flex when towing results in sway...
Conclusion..LT tires with less flex will reduce sway when towing with a 1/2 ton.
To the O.P. I put E rated tires on my 1/2 ton truck. I keep them at 45 psi when I'm not towing because i haul frequently, and 60 psi when i tow. My camper has a ton of space and almost 2000 lbs c.c. so we pack heavy for long trips. Tongue weights are often 900 lbs. I have noticed a huge improvement in towing stability since upgrading to LT tires.

I am planning on getting the tire minder monitor system for the trailer and tow vehicle to keep an eye on inflation and temperature while towing.
Any thoughts from the 1/2 ton guys and gals would be appreciated.
thanks

I run cooper atp's xl load rating max pressure is 50psi load index 117... work great... I tow a 8000lb+ trailer with a 1/2 ton no issues...
I am not a fan of E rated tires.. if you go E might as well go get a 3/4 ton.. or a one ton....

Wow, a 4800# RAWR on a half-ton?! That is impressive.

I tow a 7500 lb trailer with a Silverado 1500. I'm at max GCVW. I like E rated tires for the stiffness and durability. I air to 35 for daily driving (per door sticker). I air to 50 while towing for some extra stiffness. If you use aluminum wheels check the max pressure for those before you increase PSI from factory spec. My last two sets of tires were Pirelli and Yokahama. No issues.

I went looking for a HDPP F150. I wasn't going to trade if I couldn't get the HDPP. The salesman and dealer were motivated to get one for me. Unfortunately, the dealer here in Virginia was able to find only 4 or 5 total and they were up in PA, and none of them were crew cabs. So I had to settle for a Supercab and 8' box. It tows great, but it takes a lot of room to turn.
The front axle is rated at 4050#, with 2286# cargo capacity.

I concur with Skybound. Did a TON of research and learning. Moved to LT285/60-20 Michelin Defenders. Much improved and VERY happy with their performance.

I switched to Hankooks DynaPro HT and I inflate front to 65 and rear to 75 when towing our 6,400 Whitehawk. It handles much better and no reduction in mileage.

I was towing a 28' 5er at 8300# loaded with a F150 Eco. I had bow wave upset issues from Large Prevosts that scared the @^%$ out of me and the wife and also a slight constant sway issue that I believe stemmed from the short bed and using that Revolution hitch with the wedge installed.
I upgraded to Timbrens, then Super Springs and finally Nitto Ridge Grappler 275/55/20 Load E to help stabilize the ride. The tires helped but for me didnt take away the sway and cross winds bucked our TV around.
I ended up trading in the F150 and got a F350. Problem solved. The Nittos did help and were relatively quite for there aggressive look. Gas mileage didnt suffer much either if anything.

Went ahead and got the Nitto 275/55/20 Load E 10 ply tires and installed the SummpSprings on the rear. The springs were really an easy install. Just need to put 65 psi in the tires and re-hitch the Equalizer 4 WDH. Might have to tweak it a little. Thanks to you all for the input.

Please report back on the sumo springs. I have been thinking about getting them.

It's not our primary tow vehicle, but I started running LT 265/70/17 load range C tires on my wives 1/2 ton Ram in place of the P series tires it came with a while back . It feels a little more stable on the road and the heavier sidewalls seem to be surviving the harsh gravel and dirt roads better that the previous P series.
