Little help

[21-WHITE-6.4]

I just got a 21 2500 6.4 to replace my 05 2500 5.9. So far I love this truck. Definitely a step up. I’ve noticed when I’m driving the rear seems bouncy. It happens at lower speeds. It almost feels like wheel hop. Anyone experienced this?
Truck is completely stock. New tires from the dealership I bought it from and tire pressures are set at 70psi. Thanks for the help

You answered your own question. With the tires at 70 it will feel bouncy thats way to much air the rears at may payload only need to be at 60. So empty you should be around 45psi front and rear for a decent ride

Ok. I’ll adjust the pressure and see if it goes away. Thanks

The lower pressures will definitely help, but will cause your TPS to go off. I adjusted mine to a lower pressure threshold using a bypass cable and JScan (AlphObd works too). I’m currently using 48 psi front and 45 psi on the rears.

Here’s my tire pressure tag for my 2020 Ram 2500 with the 6.4. It says 60 psi for the fronts and 65 psi rears for max load.

Mine was bouncing like that this week as i aired my rears to 70 in prep for hauling my camper
