reducing tire pressure when unloaded
Mostly, we drive our truck unloaded, since it's our everyday beater as well. Our truck is a Ram 2500 reg cab 4X4. How low can I safely lower the air pressure to improve the ride for my arthritic wife?

Just as easy to look at the profile.
To the OP , I don't know the answer ,but there is a way to not set off the alarm on air pressure on the 2500's. The Cummins forum has the answer .
As far as air pressure I run my front 60 all the time ,45 back when not towing 80 when towing .
Ya, shame on them :Bcummins2014 wrote:

Top row is for the newer RAM Dually trucks. 35psi will give 1,570# of carrying capacity per rear tire times 4 is 6,280# capacity for the rear axle. My rear axle weighs no more than 4k without RV. I can still load a 2k in the bed with room to spare.
YES the ride vastly improves when lowering for an unloaded to lightly loaded truck. 4wd trucks keep the fronts at 80psi!!!
No help for a 2500 SRW. No idea where you come up with 80 psi front. I have to believe his truck would be 60 psi front
I run mine as recommended on the door pillar 60 psi front , ALL the time.fj12ryder wrote:

Now I doubt I’ll reduce the pressure.
- It makes a huge difference on duallies. I just dropped mine per Cummins suggestion and was night and day. On your alarm it will just stay on as a light and won’t chime every time after awhile. I had that happen on my 2016 when I was out of spec for a bit.

Without knowing what year it is, how can you say that lowering the air pressure will set off an alarm. For all we know this is a 2000 Ram.Road Phantom wrote:

Sorry but your 2500 will set off an alarm when lowering! 3500’s not a problem.
His profile
"2014 3/4 ton dodge Ram, 5.7 Hemi"- My 2500 Dodge/Cummins NV5600 has LT265/70-17 E load range. I use 45 psi in the rears when not towing. I find 65 psi in the front towing or not works best for this trucks axle loads and 60k-70k miles of service.
