New Tires: XL or E load range?

I'm getting ready to purchase new tires for my tow vehicle and upgrade the stock passenger tires to LT tires. Our trailer has a max weight of 6500 lbs. I'm trying to eliminate the bouncing from the tire flex of the passenger tires without giving up too much in ride quality.

So the question is, given the weight of the trailer, do I need to get the E load range tires or will the XL load range tires eliminate the flexing with our 6500 lb. trailer?

Thanks!

My Tundra had XL range from the factory. They were ok but the whole experience was improved with the E range tires(BFG KO's). They are a bit stiff when lightly loaded. Try to look for a load range D.

Some of that bouncing could be in the shocks as well. Replacing rear shocks on your truck is cheap and easy. I run LR E tires and am very happy with them.

The bouncing has been there since we bought the truck brand new in 2015. I also put air bags on to help with the ride. Eliminated a lot of the bouncing, but not all.

Have you tried inflating the current tires on your truck to the maximum recommended pressure noted on the sidewall of the tires? If not, I'd try that and see if that reduces the "bouncing". It might give you a better idea how much of your problem is actually the tires.

Yes. I inflate them to the max (44 PSI) just before hooking up the RV.

I would just go with the LR E's. I put a set on my Tundra for the summer towing and the overall ride was much improved even empty. No more wishy-washy floaty feeling. I ran the tires at 60 PSI rears and 50 PSI fronts all the time. After all, I bought a truck! If I wanted a Cadillac ride, I would have bought a Cadillac!

Yeah, I think I've decided on going with the E LR tires. Just not sure which ones I want. The Coopers look good, but I really don't need an all terrain tire. My truck is RWD and we never have any reason to go off road, other than the occasional short fire road. Our climate is pretty mild, too. We don't get any snow.

In your case, a nice highway tread will work great and give the quietest ride with the best fuel economy. If you want something that will handle wet grass, soft dirt/sand and fire roads with any elevation, you may want an all-terrain.

Check out the Bridgestone Dueler AT Revo 2. They come in 10 ply (LR E) and have good grip and highway manners. My dad has them on his F150 and they have been great.

Don't know your size but these come in P metric and LT.

These will be my next tires for my Tow Vehicle.

Lots of folks run less than max pressure on the load range E tires to improve ride, especially when not towing. There's a load vs inflation pressure chart around here somewhere, but my rule is a minimum of 50 psi.

Thanks to everyone who replied.

I just placed an order for the AT3's. Hopefully they'll be in early next week so I can install. I'm sure between now and then I'll freak out a few more times about whether or not I made the right call.

tylersdad, I'm assuming you have your new tires by now. How do you like them? What exactly did you purchase? I'm debating on whether or not to go up to the 10 ply load range E on my next set.

I have a 2013 F-150 3.5 EB with 3.73, 6.5' box and max tow. The OEM are Goodyear SR-A P275/65R18 tires. I've been okay with the Goodyears but they are starting to crack so its time to say goodbye.

I am looking at replacing them with Michelin Defender LTX M/S. Should I go even farther and get the 10 ply load range E tire?
Trailer is a 26BH with an actual weight 6100 (scaled).
The differences in the tires according to Tire Rack:

OEM Goodyear SR-A
Load 2601
Max PSI 44
UTOG 500 AB

Michelin Defender LTX M/S
Load 2806
Max PSI 44
UTOG 800 AA

Michelin Defender LTX M/S Load range E
Load 3415
Max PSI 80
UTOG N/A

If I go with the load range E will my OEM 18" Ford rims take the 80 PSI if and when I pump them up that high?

I'm leaning towards the non-E since this is also my daily driver with only 8 to 10 camping trips, usually within 50 miles, per year. Plus going up to just the LT tires I'm gaining 205 pounds of capacity per tire and I assume a stiffer sidewall.

Opinions?

Definitely Load E, after all you’re putting them on a tow rig not a passenger car. You can always air down a bit if you’re worried about a stiff ride. An accident do to a blown tire because you had insufficient tires is simply avoidable.

Get the load E tires but don't air them to 80. You're not that heavy. Air them to whatever your door jamb sticker says for your daily driving AND towing. Your can run them a little higher for towing if you'd like, especially if you're nearing the truck's max payload. The tire's inherent stiffness makes the towing more secure. The air pressure number is directly correlated to max payload weight.

We just got back from an 800-mile round trip adventure. The tires performed really well. I don't think we lost anything in terms of gas mileage. The truck definitely felt more planted when towing and had far less bounce. The tires are much heavier, so you feel bumps a bit more when not towing. They are a tiny bit noisier than the OEM tires, but not enough to be all that noticeable.

I'd purchase these again.
