To add another dimension the P vs LT argument, I run all terrain tires due to places we like to camp. P rated all terrains typically have shallower tread depth than LTs.

I'm considering moving to mud terrains or similar next time, though I don't relish the road noise. Maybe a set of chains are in my future too. :)

Initial depth is one thing......at the end of a tires life, an LT and a P metric still only have a 1/4" of tread or less, so traction is the same!

Have not looked into the XL version tires, but at one time, I believe it is still truck, you need to derate a P metric when used in a truck or trailer application by 9% of the sidewall load ratings. Then again, LT tires, not sure about P metric, when used at speeds under 25mph, you can increase the sidewall amount by 50%!

Reality is, there is NO BEST tire brand or tread. Only what really works BEST FOR YOU! I know folks that swear by Michelin EPS ribs......you could not give me a set! UNLESS, it was a rwd rig, put ONLY on the front steer tire, and I had some EDE M+S or the most recent variation of it on the rear.

At the end of the day, make sure the rubber is round! Otherwise, you will not like how things handle......

A lot depends...mainly on how you drive and how you use your truck

IN the old days...going from "P" clas (passenger tire class that must be derated min 9% when used on pickups) to the next higher class "LT" (light truck class) was a good thing if you used your truck as a truck more than a car

But...with the lower profile tires (lower numeric aspect ratio) has thee sidewalls much shorter and stronger than before on 'P' class tires...heck, any class tires

Because of that lower profile sidewall, it is stiffer than before and most half ton trucks really don't need to move up in class...unless they are really pushing their trucks ratings by going close to...at the the limits/raatings

There is also more to it than just changing tire class. There are other attributes to that system. Mainly the wheels. They must be able to handle the higher PSI's and service duty. Also, make sure your pressure sensors are good for the higher class tire pressures

Ok fwiw I have had heavy bed loads, skid of tile & tools to 2,400 pounds & others. That was about 8,200 IE too much. Max combined axle is 7,800. You really don’t want beyond that. I tow TTs & boats commercially sometimes with MC or snowmobile in bed to 15,800 CVW over 6 percent grades, others through windy plains & Wyoming. I’ve been through a lot of tires & I actually know how to use CAT scales & WDH to set up a safe stable tow. ED has 440k. I go through 2 sets of four a year.

I’ve run a few sets of stock size GY Wranglers SL standard loads. A set of Michelin Defenders. A set of Sumitomo Encounters several sets of General Grabber HTS 60 all season XL loads in 275/55/20. MY19 Ram & Ford & GM all now use this size. I have two sets of stock 20” rims. One with 265/60/20 General Grabber HTS 60 all seasons E loads.

For a truck that is loaded correctly according to Mfg specs scale proven and 2,000 pounds or less per tire IE our EDs I’ll never waste money on another set of Es compared to the little lower profile XLs. They are heavier take more fuel cost more and make for an unnecessarily harsher ride and provided no descernable benefit again on our trucks and at 2,000 pounds or less per tire. If that is a fair price to pay for peace of mind then buy you some Es. I will on 2500 or greater but not on a 1500.

I believe for the stock sizes there are only two tires you can get. BFG KO2 and General Grabber ATX. I got the ATX a couple months ago and like them so far. Ive got 8K with about 2k towing on them. There are other XL tires but those are the only D and E tires I know of.

BFG AT T/A KO2 is one of the few LT tires that come in the OEM size, and has a good reputation.

I would say that if you want the performance of a truck tire, get a LR E.
