Probably nothing to most of you... but i put new tires on the F150 and went with Michelin Defender LTX, which comes in both D & E, I chose the E. I don't recall what tire the truck had, somebody had suggested it was B range... but IDK.I'm only towing a 5k trailer, but what a difference this tire upgrade made. Used to be if a semi blew past me at 10 over my speed, or a full size truck at 20 over my speed (65mph), I'd feel a little wiggle. NOTHING, NADA, now! There's also less bounce with and without the load leveling bars.Without a trailer, the tires are slightly noisier, and slightly rougher ride.We're doing a big trip soon, and while the old tires with 50k miles on them still had lots of wear left, I didn't want to tow the trailer a long distance and possibly in snow with those tires.

Lots of 150s using E-rated tires for load carrying/towing. I am curious what air pressure you are using for towing. I have a friend using Es on his 150, and I think he runs 55 front 65 rear when towing. Personally, I would have purchased the Ds, if given the choice, and run them at max on the rear, when towing. JMO, and surely opinions vary. Glad yours are working for you, and your towing improved.Jerry

New tires are always a wonderful addition to every vehicle. If I was made of money I'd probably get a new set every year just because I could. That said, proper LT tires, ideally E rated, are a must for me. C vs. E range is pretty much a no brainer. I'm not surprised one bit that you are happier with your LT rated tires vs. the P metric tires they replaced.

When I went from P rated tires to LRE tires on my Tundra years ago I was expecting a big improvement towing. I couldn't tell the difference. Even when I went to the bigger trailer and I towed with P rated winter tires vs the LRE tires I didin't notice a difference either. Glad you are happy and notice an improvement, I just never did.

Glad you noticed the differenceNot just weight carry rating, but stronger/stiffer/etc sidewall and the rest of the carcass Only part of the reason class "P" tires used on trucks, RMA recommends (require) a min 9% de-rating of the sidewall molded ratingsThe rest of the suspension also matters. Like wheel ratings...off-set, PSI & Weight. If course, the tire OEM recommended rim width range (bead to bead)Finally, PSI requirements are different between these 2 classes if tires for equivalent weightsWhen going next class higher, also note that the tire PSI sensors may NOT be rated for the PSI's required

Don’t be a bonehead and run full 80psi. Weigh loaded and unloaded. Use weight inflation chart for your tires. Add 5 psi to rear and 10 to fronts. You will get best ride, tread wear and stopping.

Your tire sticker only applies to the OEM tire.
