I'm having the same issue at 55psi all the way around. Drifts all over the place. Will drop to 45 rear and see what happens. It's weird because my Nitto 10 ply were all running 55 on my last truck per Nitto tech recommendation and had zero issues.

How long have you had the truck? Tires are always slick for the first few hundred miles, sometimes up near 1k. Gotta wear off the top layer which is the oiliest from manufacturing.

Tire pressure and initial break in on the duratracs made the difference here, all were 58psi for the first couple hundred until I checked and realized that's why the truck wandered around on bumpy back roads

Took the psi down to door sticker level and it rides great

My truck has 1100 miles on it. If anything it is getting worse as I added miles.I will air down in am and take it for a ride. Still has to go back to dealer as they delivered to me with white stains on the black grille they need to replace.

It's definitely not normal, and not only from tire pressures. My tires are at 60 all around (because that's how I drove it off the lot and I'm lazy) and have no issues with ride quality or directional stability. Roads here in MA aren't super smooth and I've driven down some really corrugated dirt roads at a good clip with full confidence. Tire pressures might be making the issue worse, but not the main factor.

Hopefully the dealer can get it sorted for you. Let us know what happens.

Drop your tire pressure to 55 up front and 45 in back like others have said. Mine came from dealer ship at 65 all around and drifted/wandered on the highway badly. Dropped to correct pressures and now it drives like it should on highway.

I too had the same problem as op. I lowered pressure to 50 front 45 rear. Much better but still not as solid as any of the past 10 trucks I have owned including my 2018 ram. I’m going to try the wheel spacers too and see if the wider track helps.

My wife’s suv has adjustable steering wheel weight which makes the wheel easier or harder to turn. Could it be the power assisted steering need a tweak at highway speeds to make it a little less twitchy.

Not yet. I just got the truck. Its going back to dealer later today which is 100 miles away. After buying 3 new rides a yr (on avg) for the last 15+ yrs, an aliment needed and\or wrong tire pressure from delivery is a 1st.

I needed an alignment on my last brand new Toyota as back tire alignment was way off. They covered it and did front while they had it and the front was a little off as well. So it does happen from time to time. Checking and adjusting tire pressure is a dealership thing that they are supposed to do some do it some forget or don’t bother not sure which.

Yea, it should be part of the PDI

why is there less air required in the rear? I have mine set at 58 al four corner and drives perfect, and I tow a 7000lb trailer. any other truck Ive seen always runs more in the rear, not less? reasoning??

Yes, that is the way I have always thought of it, When you add tongue weight of a trailer and the payload in the bed, I would assume you would have more weight over the rear axle than front.

This truck has a 1970 lb payload, and its intended purpose is toe be my winter ride that has a sled deck and 2 sleds in the bed, so I will be using all the payload. Load range E tire that max out at 80, I would assume I would want at 80 with that load..

I'm not trying to jump on anyone here, but the OP stated that it was "borderline unsafe". So are some of you people saying that a difference of 15 psi on the rear tires is going to cause a "borderline unsafe" drive condition? A solid axle, body-on-frame truck, capable of towing 11,000 lbs, 1500 lbs payload, go up Cliffhanger 2.0, and take on any number of situations is going to be severely hampered by 15 psi of tire pressure?

If you were telling me that it's tire pressure on a McLaren 675LT set up for max attack on the Nurburgring... fine. If you're running <25 psi on the street... ok. But 60 psi vs 45 psi on a truck designed to haul heavy loads down dirt roads, etc? Sorry, but saying this can all be solved by changing air pressure and no need to take it to the dealer to have it checked out is a little irresponsible. Please, drive the 100 miles and get it addressed. If I'm wrong... awesome. Happy to be wrong. But 15 psi of tire pressure difference should not degrade vehicle dynamics to an unsafe condition. Certainly not the case on my truck, which hauls my wife and kids every day.

Captain CJ35..... I agree with you 110%. It is so bad I asked them to bring a flatbed to come pick it up. Even if the air pressure change makes some improvement, just as you say, what happens when I do have that load?

The reason I was driving the Rebel yesterday was to pick up a Sled Deck. It weights about 400 lbs and I felt that it was unsafe to transport, so I decided against loading it up.

The correct tire pressure any tire will be determined by the weight it is carrying. So if your towing 8000lbs with 800lb tongue weight you should up your tire pressure accordingly. When truck is empty reduce air pressure accordingly. When your contact patch is the whole width of tire (from edge to center)your tire pressure is correct for said tire/weight ratio.

The tag in truck stated the tire press for GVWR , which I assume is loaded, is 55/45. There is no stipulation on the tag for towing and airing up

Something is decidedly wrong if that's the case. Is it pulling one direction more than another? Any clunks or noises from the suspension? Does everything look right under the truck? If it's that bad, you might be able to see what the issue is.
