I intended to get LT 275/65R18 load range C when ordering my truck but ended up with the P metric 275/65r18 Goodyear Wrangler Fortitude by mistake

They are very bouncy and I think they are contributing to some sway when pulling my fifth wheel.

From the factory would have been the Goodyear Wrangler AT Adventure with Kevlar. My previous F150's all had Wrangler AT/S.

So my questions are: what LT tires do you run?
Do you have C or E load range? How is the ride?

I prefer C for the stiffer sidewall vs p metric but still not as stiff as a E range. There are not many choices to pick from in load range C in the size needed.

Thanks

I would not tow my tandem flat bed with P tires, let alone a fifth wheel! Do they not make D range tires in 18"? Seems like I only see D in 17".

Can't find any D's and C's are pretty scarce too.

the newer 150's don't handle as well as the previous generation. I'd recommend the cooper AT3 10 ply. I have the LT wrangler on my 2016 but I haven't towed anything yet. My 2012 lariat had LT wrangler as well but when they wore out I upgraded to 10 ply coppers. You won't be disappointed by either as long as there 10 ply. IMO. Good luck.

I run Michelin Defender LTX (highway tire as I don't need AT) LT 275/65/18. Made a huge difference hauling bed loads full of firewood. I had the P rated tire squish and the truck didn't feel stable. With the E rated LTX's, the truck feels much more stable and planted.

If I had needed AT, I echo Bill The PA, I would've gone 10 ply AT3. I had AT3s in P before I switched to 10 plys. Definitely recommend for AT if needed/wanted.

As far as ride goes, it's just fine for me.

there are lots of load range c tires available in that size. I've got 70M miles on my Goodyear Wrangler AT LR C tires and there is a good 5M left in them. Load Range E is overkill. They just make for a rougher ride.

Bill_The_PA

to some "E" rated might be overkill however if the OP tows allot, especially weight over 8000lbs then I'd highly recommend it. As I and others have stated before on this forum, the new generation F150 are more jittery and seem to have a loose handling feeling. Any side gusts from Transport or wind only magnify side to side motion. A stiffer sidewall would most definitely help. To the OP. If you're not that situation then I'd say do a swop at dealership for the LT 275/65/18 Wrangler and pay the $350 difference. (Pennies/month). Good luck. BTW I think that wrangler ( with Kevlar ) was rated # 1 or 2 by consumers report and the Cooper AT3 was # 1 last year.

Check tirerack.com for tires. You will see what's available and see other people's ratings for each tire.

Also, I don't see HD payload package on your sig. Some of your issue might be your truck's payload capacity versus the actual pin weight of your 5th wheel.

Bill_The_PA

agree. That's usually the limiting factor.

I've had Michelon LTX MS/2 LT-E's for about 50K miles mostly towing and have been running them at 60 psi, rotated every 10K miles. Do like them a lot but they all are wearing too much on the sides like they are under-inflated. (My axle weights are much less than they can support at 60 psi.)

Maybe you have to run these LT-Es at their max 80 psi to wear evenly? I'll be upping the psi on these to see if I can get more miles out of them.

And if you want to run at 50 psi, you might get better wear out of an LT-C tire, or an LT-D at 65psi (their max psi's)?
