Ok folks here is the latest on this issue. There are ALOT of Ram owners that take issue with this 60/80 PSI BS. From the Cummins/Ram forums:
How to set TPMS to ANY pressure - Dodge Cummins Diesel Forum
HD Tire Pressure Monitoring System Reset - DODGE RAM FORUM - Dodge Truck Forums
Apparently dealers were able to lower TPMS thresholds until FCA released an update to their scan tools taking the option away earlier this year. This is all thanks to the federal government regulating every vehicle under 10000 GVW. 3500s have a TPIS; just an indicator system, no alarms.
There are apparently a few ways to work around this:
-There is a shop owner/tech in Birmingham, AL that spent thousands on code software and has a fix. He no longer charges $100 to change it, he will do it for free if you bring your truck to his shop. You will need your trucks PIN(key) number obtainable from the dealer parts dept. He has done TPMS tours of parts of the country fixing peoples trucks.
-Find a willing dealer that still has WiTech1 equipment that has not been updated. WiTech2 equipment will not work.
-Use a Bully Dog tuner to change the thresholds yourself, then bring the truck to dealer to do a "RFH Replace" reset (WiTech2 can do this).
I go through Mobile, AL a few times a year and plan to detour to Birmingham next trip out.
