I'll have to go back and look at the tires again. It was getting dark when I looked so I may have been mistaken. Marc is at work and won't be home until around 6. I'll take a look again when he gets home.

How about you provide the size of the tires on both TVs vehicles, or for that matter all three.

This problem has to be specific to the Ram pulling it.

Oh, I have no doubt the problem is specific to the Ram, specifically it's too light duty a truck. I have a Ram 1500 QC, 4X4 5.7, 3.92 in my fleet and there is no way I'd tow a trailer over 6,000 lbs (loaded, not dry weight) with it. Rated Payload is 1497 lbs and the rear coil spring suspension is cushy but not great for load.

Check the wheelbase, tire size and tire pressures on both vehicles. ....and as I said before, the ProPride won't help being over payload but it will stop sway.

2 cents,
Dave

I had to run up the road with my tractor and grooming mower to mow a small field for my daughter and I saw Marc's truck in the driveway. Apparently he moved it last night from behind his house to the other side and took his car to work.
The Ram tires are:
Faulken Wildpeak A/T M&S LT 275 R 18 Load Range C
Trailer: JAXXON ST 225 75 R 15 SPR
My pick up: Cooper Discoverer M&S standard load 265 75 R 16
Suburban: Cooper Discoverer M&S standard load 245 75 R 16

Dave, can you send me a link to the website for the hitch you mentioned?
I'd like to see what is different about it.

I think this is what always surprises me. My payload on my midsize Canyon was over 1400 pounds. The spread on half ton trucks is so great, I can't imagine how you can just say I want XYZ truck without literally seeing the label on the door.

I tried to look at the Ram site for payloads and tow capacity, and they give you a bunch of warm & fuzzy numbers, but I couldn't find anything specific to an OFFROAD Ram truck. OFFROAD designations typically result in lower payloads, etc. than the base versions.

The Ram towing guide will tell you and you can look up models or a specific VIN you are looking at:

I looked at that page, but I couldn't directly find the truck he described. Further, the pages it sends me to just list the max towing, not the actual, label numbers.

Let's face it. A 1/2 ton truck is only good for towing 5000 lbs. Above that all bets are off. You can mask the problems with wd and sway control hitches and other measures but you'll never be totally safe.

tuffr2 · 07-26-2022, 06:45 PM

I would not have guessed the rear coil springs could cause so much towing issues with trailer sway. Trailer sway is nerve-racking.

I did tow a 5,500lb 26.5' travel trailer rock solid with a 2011 F-150. No sway nor influence from semi's I passed at 72 mph. This same trailer at 4,700lbs was a nightmare behind a Gen 1 Honda Ridgeline so I know how nerve-racking trailer sway can be and towing slower than normal flow of traffic.

I think this 2011 F-150 could have towed 6,000lbs and maybe 6,500lbs if I wanted to push it.

If it is super important to you, find a truck on cars.com that matches what you want to find, get the VIN, then place it into the site. It does give you numbers that match the VIN, based on my own VIN and sticker.

I have the same truck, Quad cab. The issue is the coil springs. They are too soft, so you need to put heavier rear springs on or add a load leveling bag system on the truck. The GM has leaf springs, which are not as soft and hence a rougher ride. I had a Ram 1500 with the automatic air leveling system and I towed a 28 ft enclosed car hauler with 2 fiberglass vw dune buggies with no sway bars at 70 plus with no issues.

Coil springs are not intrinsically soft. Ram uses variable rate coil springs that are soft at low loads to give you a comfortable ride but when you put load on them they become just as stiff as leaf springs. I don't think the OP's problem has to do with the coil springs.

JIMNLIN · 07-26-2022, 09:06 PM

LT Load C tire on a std duty 1/2 ton truck is a great fit.
For towing duties the rear tires should be ran at 50 psi (max sidewall pressures regardless of what the trucks tire placard says as the rear tires/suspension is carrying all the trailer hitch weight.

Tires like mud terrains (MT) or even some AT with large voids and lugs can have tread roll and contribute to sway problems

OP mentions truck bounce front to rear. That can indicate pogo stickin' or porpoising and can be caused soft rear suspension for the load carried.

The wife 2016 1500 chevy 4wd crew cab 4000 rawr P tires did that with my 10k car hauler with a Husky Centerline TS WD hitch. With only 1120-1180 lbs on the trucks rear axle it had a bad case of pogo stickin'. A pair of Sumo rear springs eliminated front to rear bounce issue.
When towing I keep the P265/70-17 tires pumped to the 44 psi (max sidewall pressures).

I as many who responded have never owned a 1500 Ram with coils so I won't bash the product.
Way too many 1500 Rams out here with the rear coils out here with no sway issues to blame it on rear coils.

Some times it cab be a combination of 2-3 small things that can cause sway issues with a TT.
