2014 ccsb 3500 Laramie manual trans. No tpms light. Picked up a screw in the right front, pressure was all the way down to 32psi, and no light or warning message. Thoughts?

Perhaps the sensor was still “asleep” and had not been driven enough to communicate with the module.

Truck was driven at least 5 miles, and dash was showing that low of an air pressure

I thought 3500’s only show pressure. Thought warning light was on 2500 only.

Great eye......I overlooked the fact that it is a 3500.

3500’s actually have TPIS (tire pressure information system) and do indeed simply report the current air pressure WITHOUT throwing any notifications if a tire gets low.

Since the GVWR of any 3500 is greater than the 2500’s GVWR of 10,000 lbs, TPMS is not required by Federal Law.
