OP are you positive the issue is with your tires? I have a 2011 Ram 1500 4X4 and after talking to Ram, I installed a set of Firestone air bags in the rear springs to help manage the load: problem solved. Ram decided to install the air bags standard in the new trucks due to your problem and others.

They've been on the Dodge for two years now - really pleased with the way they've performed. Especially while towing.

Okay thanks. Good to know. I will have to take a look into those as well. Thanks for the information.

a Load range E tire will help stabilize the ride when towing due to more ply's in the side wall of the tire

I have an 04 Dodge and run 18" rims and tire combo
My truck came stock with the 20's but since I did a lift I had to go with diffrent rim due to back space requirments.

If I could do it all over I would have rather stayed with a 20" tire because I noticed the 18's make the truck ride diffrently - has more mush as you would call it - not exactly sure how to explian the diffrence other then that

My truck used to have alot of side to side motion when going around corners so added a rear sway bar which helped alot - I think the 2010's came with sway bars from the factory but from what I remember seeing they are about half the size as the one I installed from Hellwig.

Does the truck bounce up and down and back and forth when towing? or does the back end squat considerably? I have no experiance with air bags but do know my parents used to tow a 5th wheel on a 2500 dodge and it bounce before they added the air bags and also helped stabilize the level of the truck too

I get a side motion, but not a rocking back and forth it's more a squirmy feeling out the back of the truck like driving on grease.

Yes the truck did come with a stabilizer bar, but as you mentioned I can bet it isn't as big as an after market one. The truck doesn't really sway at all when cornering etc, it's just that squirmy feeling when going down the road.

The truck doesn't squat at all when the trailer is hooked up, but I have airbags installed inside the coils and have them inflated to 40 - 45 psi when loaded.

I get some porpoising at times, but from reading various posts and hearing from members on the forum that may be being caused by a combination of problems. I'm starting to think the bars on the WDH are not heavy enough. They are 800lb and probably should have gone with 1,000lb.

Also the airbags could be causing some bounce, so going to change out to a heavier duty shock of some kind.

Hi Frank,

Yup had the airbags installed before we picked up the trailer.

When were telling our sales guy at the Dodge dealership that we had bought a TT, that was one of the first things he told us to do was get airbags installed.

bilstein socks are the way to go - kinda pricey but well worth it

does the trailer sway? that squirmy feeling to me would think you have sway
does it happen all the time or just at highway speeds?

When I got my 05 Silverado it had P tires on it and we towed a 31' t trailer with it and even with 50# in the tires it was squishy even tho' I also had air bags. Changed to LT E with 65# for towing and it made all the difference in the world. No more squishy feeling and when not towing, I let them down to 45# in the tires and 5# in the air bags and it rides just fine. Not as good as our old broken down 96 Deville, but it is a pretty smooth ride.

Yes I'd like to get Bilsteins. Not to many shops here carry them. They are mainly Monroe pro, but figure I'll try to get the shop that does my tires to put them on at the same time even if I have to order them in myself.

I get bad sway at times and going to change the WDH out one that has sway control.

I've noticed the squirmy feeling even at 45 mph. It's hard to describe it's one of those feelings you get in the seat of your pants. Even though the truck is locked down to the road it feels like the back of it is on black ice at times, but not all the time. I raise the pressure on the current P-metric tires to 40 - 42 psi when hauling.

The tires are due to be changed out anyway, so now is the ideal time to get something with a heavier sidewall.

Yes I'd definitely would like to get a LT tire, but are hard to come by in 20". Have managed to find some here with an "E" rating. Was told about Good Year Wrangler Silent Armor, so will look at those as well.
