Problem with the new Ram 2500's IIRC the TPMS won't allow you to air down to 45 PSI. With my 12 Ram 2500 CTD the front weighs 4800 lbs. Door sticker says 65psi. Rear weighs around 28-2900lb. Door sticker says 45 psi. I have upgraded the tires to a larger tire with a higher load rating. I still run what the door sticker says. 65F, 45R. Last time I went to Discount for a rotate they said they were wearing perfect.
You don't need big psi in the rear. It weighs almost 2000lbs less than the front.
But if you can't lower the psi in the rear then what do you do? I doubt shocks
will help all that much if you can't run a lower psi in the rear.
You can, you just get the tire light on.
Dealer software can't re program thresholds anymore but there is one aftermarket product that will now but it's spendy.
