Tire Fill Alert ?

[odinjunior]

So is Tire Fill Alert the same as TPMS?
If I uncheck the display can I run tires without sensors ?

Sorry if this is common knowledge but this is my first 3500. My 2500 would tell me how much the Tire Pressure was.

All 3500's have is a monitoring system, no alarm. I "ASSUME" you can run without sensors but I like to keep an eye on mine.

I have been running since 2016 without TPMS sensors in my summer towing tires on my 2500HD truck. I do get the idiot light and 4 dings upon start up, but no other issues. I run these at a different air pressure than the factory preset so, I would still get a low tire pressure alert. So, I saved money by not installing them. When I install my winter tires which have the TPMS sensors in them, the idiot light goes away and the dings are gone until towing season.

Reason I ask is folks around here like to put new wheel packages on their trucks and a set of wheels and tires without sensors can be had for $1k.

Sensors are cheap, buy them and have them installed.

You won’t get an alarm without them, but TPIS is a great tool to maintain.

Tire Fill Alert is different. When activated the hazards will turn on and you can start filling a tire. The horn will chirp when the recommended pressure is met.

From a 2020 Owners Manual:

Tire Fill Alert This feature notifies the user when the placard tire pressure is attained while inflating or deflating the tire. The customer may choose to disable or enable the Tire Fill Alert feature through use of the customer settings in the radio. NOTE:  Only one tire can be filled at a time when using the Tire Fill Alert system.  The Tire Fill Alert feature cannot be entered if an existing TPMS fault is set to “active” or if the system is in deactivation mode (if equipped). The system will be activated when the system detects a increase of tire pressure, while filling the fire. The ignition must be in the RUN mode, with the transmission in PARK (P). NOTE: It is not required to have the engine running to enter Tire Fill Alert mode. The hazard lamps will come on to confirm the vehicle is in Tire Fill Alert mode. If the hazard lamps do not come on while inflating the tire, the TPM sensor may be in a inoperative position, preventing the TPM sensor signal from being received. In this case, the vehicle may need to be moved slightly forward or backward. When Tire Fill Alert Mode is entered, the tire pressure display screen will be displayed in the instrument cluster. Operation:  The horn will chirp once to let the user know when to stop filling the tire, when it reaches recommended pressure.  The horn will chirp three times if the tire is over filled and will continue to chirp every five seconds if the user continues to inflate the tire.  The horn will chirp once again when enough air is let out to reach proper inflation level.  The horn will also chirp three times if the tire is then under-inflated and will continue to chirp every five seconds if the user continues to deflate the tire.​

What a cool feature this is.
