6 ply or 10 ply. Would I see a difference?

I always ran LRE tires on my 1/2T trucks, and it always made a ton of difference. They do make the ride rougher, but oh well.

Are you sure the weight distribution hitch has enough tension?

Yes, it is pretty loaded up.
Either the tires or springs are flexing too much.

I have my first full size class 1/2a truck. I have XL at best on it. Reality, at full psi, I have not had any issues hauling, towing upwards of 8000 lbs. Altho both trailer were a bit light on the hitch. I want to replace the tires I have, as they only really work on dry pavement, Put any amount of liquid or equal....worst tires I've had in many years, going back to late 70s using hwy bias ply tires were better than these!
With this said. I noticed no difference between 8ply and 10 ply 265-75-16 tires on my SW 3500's Ive had. Assuming I was under the 8 ply rating. I still only had the 10 plys at the same PSI, because if I put more than the typical 55-60 lbs I ran, the tires only contacted the middle part of the tread, not the outsides.
My gut feeling is frankly, you will not notice the difference, ASSUMING you have the same tire brand etc.
Change out from a cheap soft sidewall tire, to a stiffer sidewall tire of the same ply rating, you probably will notice the difference in handling. at least I have.
As also noted, "IS" your setup, setup correctly? If not, you WILL have issues with towing, handling etc. THAT is the first place you should look. not spending money on tires etc.

Most tire stiffness comes from inflation pressure. Have you tried a bit more - like +5 psi?

Ply rating does not really mean anything any more.

What is important is the load rating, in pounds, which is on the tire side wall.

"ply" rating has kinda been replaced by load index 3 digit numbers.

118, 121, 124, 128 etc - lets you tell at a glance if the tire you want is in the capacity range. Then go to the mfg spec sheet and look at the single load rating.

All this specing and matching of tires starts with weighing your truck and trailer and tongue weight with and without weight distribution set up etc

Anyways - when I have set weight distribution too tight or used the wrong rating bars for the tongue weight, I've experience "bouncing" in the tow vehicle.

"Soft" tires - by this I mean underinflated or overloaded for their index - contribute to fluffy ride and more instability in the lateral plane vs the vertical plane in my experience.

But when I get a different truck or trailer or camper or whatever I start by a visit to the scale and get some weights recorded.

Ply rating means a lot still. If you can get 10 ply, why not have a peace of mind that you did all you could? Blow outs during a trip are dangerous and destructive. Keep that in mind as you sit on side of the road with all the damage you now need to fix with all it's hassles. Try getting parts now. Plus trying to change out the tire as traffic wiz by. Just put the 10 ply and hell with the minimal rough ride. Safety first for your family.

Would I see a difference with 10ply tires?would the ride w/o a trailer be too stiff?

Thank you

Not really.
A 6 ply rated tire should mean a LTxxx/xx-xx load range C at 50 psi which has plenty of sidewall stiffness for towing duties.
Moving up to a 10 ply will be LTxxx/xx-xx load range E at 80 psi. Your F150 wheels can't take those kinds of pressure unless your truck is the F150HDPP that comes with wheels rated for the higher pressures and loads. A load C is a good choice for a std duty 1/2 ton truck.

The advantage of the E tire comes only at those higher pressures....which most 1/2 ton truck wheels aren't rated for.

Pump those load C tires to 50 psi max sidewall pressures.

Not sure how you buy tires by 'ply' anymore.
