Bouncing on certain interstates with stock tires

[DJElliL]

Hey everyone,

I have a 2020 Power Wagon and the bouncing at interstate speeds is almost undriveable (on some interstates only, I live in Salt Lake City and I-15 is the worst of all). I have some AirLifts with the internal trounce bumper that I run at 0 PSI, so I don't think that's causing it. I keep my tires between 55-60 PSI, and also have tired adjusting them as low as 50 and high as 70. Does someone have any ideas - or is there something I might be overlooking?

Try 40 PSI front, 35 rear. That's still slightly over inflated for an empty truck based on the vehicle weights and the tire inflation chart for the OEM Duratrac's.

as said above no need to be running even 50psi in an unloaded pw.

Is the road concrete or asphalt here in Edmonton the Anthony henday freeway is concrete and the expansion joints are terrible in a full size truck the missus hates it cuz it makes her ***** bounce lol

I will re-affirm , 35 in the rear, 40 in the front. World of difference!

Some concrete highways are incredibly bad when it comes to bouncing, especially when pulling an RV. Slowing down may help, but it's the fault of the highway more than the truck.

I have the same issue In Colorado with the concrete roads. I concur with the above. I run tire pressures at 40/35, but the biggest difference was made when I changed the stock Bilstein 4600 shocks. I tried the 5100 shocks first and that helped quite a bit, but when I upgraded to the Thuren springs and Fox shocks helped the most. Still bounces over the joints, but is smoother and doesn't rattle my teeth anymore.

I15 has some of the worst expansion joint problems I have seen in Utah. When they were first built they did not lock the joints together and they were really bad. Later they went back and tied them together to help keep the road smooth. With all the freeze / thaw cycles you get a concrete road will always heave in these condition. I drive the length of Utah several times per year and you can even feel the joints in places in my MB S550.

She may hate it but I am willing to bet you take that freeway as often as you can!
