Is the 3500 TPMS still a monitor only, or does it have set points? I like to run 52 front and 45 rear unloaded on my '06. Tires do very well at those psi's.

That's what I understand. I am at 59 all around in mine. I just brought it down from the 80 the dealer had in them. Try it.

I'm not aware of any way to change the tpms trigger pressures other than with the Witech diagnostic software. I have the dealer software for my fleet on the North Slope and have lowered the pressure threshold on a couple of the trucks. 14s and 15s. Min setting is like 30 psi iirc.

The TPMS settings are set by the TIPM if I recall. The scan tool from AutoEnginuity can raise or lower the set points if the dealer won't do it or tells you they can't do it.

AutoEnginuity can change TPMS thresholds and they are located in the Radio Frequency Hub section on the 13+ trucks when you connect.
