Just like most recent iterations of General Motors pickup trucks, the all-new 2019 GMC Sierra will offer a Tire Pressure Monitor System that monitors the tire pressure of the truck’s four. But the new Sierra extends that functionality to the trailer thanks to a new Trailer Tire Pressure Monitor System.
Let’s take a deep dive into the new trailer TPMS in today’s installment of the GM Authority Feature Spotlight.
The Trailer Tire Pressure Monitor system in the 2019 GMC Sierra is comprised of four wireless tire pressure sensors that are shipped with the truck and installed on the trailer’s wheels. This enables the sensors to relay tire pressure and tire temperature information to the “app screen.” In this case, the app in question is the myGMC smartphone application, which also includes other trailering assistants, including Trailer Light Test and Pre-Departure Checklists.
We’ve also reached out to GMC and verified that the trailer tire pressure will be available in a page of the Driver Information Center (DIC) – the digital screen that’s located between the gauges in front of the driver.
Notably, the high or low alerts provided by the trailer tire pressure monitor are based on the following two factors:
- The values input by the customer during the trailer TPMS setup process, and
- The reading of the trailer TPMS sensors based on #1
To note, the “normal” values for the trailer tire pressure are located on the placard of the trailer, provided by the trailer manufacturer.
The Trailer Tire Pressure Monitor System on the 2019 GMC Sierra is available on the SLE, Elevation, SLT, AT4 and Denali trim levels, typically in conjunction with other packages, as follows:
- SLE: included and only available with (ZL6) ProGrade Trailering System
- Elevation: included and only available with (ZL6) ProGrade Trailering System
- SLT: included with SLT Premium Plus Package and Texas Edition SLT Premium Plus Package
- AT4: included with AT4 Premium Package
- Denali: included with (PEC) Denali Ultimate Package
It doesn’t look like the trailer tire pressure monitor system can be retrofitted for units of the 2019 GMC Sierra that don’t come with the system from factory, as GMC states that the system “must be ordered with the vehicle and installed by the factory.”
GMC states that additional or replacement sensors will be available as a GM Accessory.
