rear end sway

[AEdelheit]

Tires are not ride control devices, air them to max on the sidewall and be done ! How many miles on the rig ?

That is terrible advice and far from accurate for majority of people.

But if the tires are new and have been over-inflated they won't heat cycle and break in as quickly, which can create a squishy feeling.

Weight is weight, 1/2 ton or 1 ton with enough air to support 5K lbs the tires should be fine. A little extra air on a hot day or lots of high speed travel is a given.

I just cannot see a tire that needs a break in to drive correctly, it doesn't compute. They may harden up after heat cycles but any squirm or sway would be a non-starter for me. I have had a new set taken off and replaced when they did that kind of stuff. The only issues like that I have had are the wrong tire for the truck. Some of these tiures like Cooper and others just do not react well to a heavy truck.

Weight is weight but the difference between a 5500 lb low profile truck and a 7500 lb high profile 4x4 makes a huge difference in how the tires react. Too many of these tires are simply NOT made adequate for the high profile load the Dodges subject them to. They may be E rated and all that but if they are made for a Toyota a Ram 3500 is going to stress them.

My truck I have always had to run close to max psi in the fronts or it wallowed. Even with stock tires from brand new the steering feel always improved with air pressure in the fronts. The taller the tire one goes the more pronounced the wallow becomes. The Toyos, Falkens, and Nittos in MT and AT all handled better with 70 psi in the fronts than 55-60. A lot has to do with the sidewall strength and tire weight. The heavier tires always handled better with less air in them, seems to me that is a direct correlation in most cases.

I like less than factory air in my 37'' toyos but for aggressive cornering they should have more on the pavement

When my KM2's were new they were horrible, and I mean horrible!!! But they did some sort of break in and now are a very solid tire, other than they wear quickly. It happens, and I read about it often enough to know it's relatively common. In fact when I went to 19.5's I expected a ton of squirm based on the reports of others, but I didn't get any... at least nothing compared to my KM2's when new.

How is that?

There isn't a single tire manufacturer that would agree with you. If you scroll up and you can see many of the reasons why it's a bad idea. The only good thing it does is allow for a lazier driver.

1st Saftey and traction, the rear axles of these trucks have about 3500lbs on them, inflate the tires to 80psi unloaded and drive on ice see how it goes. On any tire you want an even contact patch across the tread, to much pressure and the center of the tread will provide a narrow contact patch as the ousters are lifted up and too little pressure the center folds in and the outers will be the contact patch, proper pressure for the load and the whole tread is the contact patch.

2nd the center of the tires will wear out and severely shorten tire life so now your just throwing away money.

3rd they are absolutely "ride control devices", the sidewalls flex use that to your advantage and save your back. Small chop like wash board roads are the hardest to get the suspension to move on and if you have the proper inflation for the load the sidewall will absorb alot of that, put it at 80psi unloaded and hope your insurance covers back issues.

You might want to pack a lunch when you air these up and down

Maybe a bomb suit would be in order before you air this one down

Maybe I'm in the minority here then, know I am elsewhere , but I'll save that for another thread ! Got 125k out of my last set on the dually and the guy I sold them to put another 25k on them before replacing them.... on my DD toyota , simple LRC 31x 10.50's have 200k on the 2 rears as of now , most of the time aired to 50-55 PSI. :--)

HAhahahahaha, ahhhhhh the entertainment of forums! We needed a new Harvey.

Have a 05 dodge 2500 couple weeks ago put new tires on about three days later going around a long curve the rear end felt like it was rolling to far to the right so ive changed the front sway bar bolts and ive checked everything put new bushings in the control arm any ideas i was thinking of changing shocks next

What size tires? What brand of tires? What type of tread? Block style tread? steering style straight tread?
A block style tread that is not interconnected to the rest the rest of the tread rubber will have "squirm" around and make the truck act as if were riding on Jello. The deeper the tread the worse it will be. Not so bad once they get worn but when new???? Look out. The more weight you pull/carry the worse it becomes. Just an educated guess as you didn't indicate what type of tires you put on but this is probably what you are suffering from. New shocks, etc won't help. How's about posting up a pic of what you had on there and what you have on there now?
Look/search "tread squirm".
