TPMS adjustment ??

Has anyone had any luck adjusting the 2019 Ram 2500/3500 TPMS system ? The Ram 3500 DRW wants 80 psi in the front / 65 in the rear. Absolutely ridiculous for the front ride quality. Anyone ??

Did they add TPMS to the 3500ís? 13-18 only had TPIS which didnít have a low warning.

The 3500s do not have TPMS.

Lower the front tire pressure until it's soft enough for you.

Every 3500 I test drove, even at different dealers, had 80 to 90 psi in all six tires. I had the dealer lower the pressures before I left.

The two earlier posts are correct, the 3500 does not have TPMS, only TPIS. You will never get an alarm. 90psi is the shipping and storage pressure to help keep the tires from getting flat spots. Definitely check that before you leave the lot. My dealer did not adjust the tire pressures at all. I have all 4 on my 3500 SRW at 55psi cold for driving unloaded and a just accordingly for payload/towing.

So that explains why mine also had 90PSI on delivery. So much for PDI...
Also RAM's website now offers a feature called Selectable TPMS Alert on the 2500's, which chirps the horn when you are adding air and the correct pressure is reached. Based on that I would guess the TPMS is adjustable.

For what it's worth, my truck was delivered with 90 pounds of air in each tire too.

I agree, nice PDI.

Oh geez, I thought TPIS was TPMS. Stupid question, so how does that actually work?

Tire Pressure Information System (TPIS) allows you to check the pressures in the tires, but there is no alert when tires get too low.

Tire Pressure Monitoring System (TPMS) allows you to check the pressures in the tires, but it will alert you if the pressures are not within a certain threshold. Can be very annoying because if you change the pressure to be conducive to ride quality and not max payload, the light on the dash comes on and the truck will ding at you.

The TPMS is NOT adjustable. I am working on getting a cable that will work on the 19s so I can see if the Autel will adjust the settings.
