Yes, the GMC Canyon's trailering app, especially with the ProGrade Trailering System or the Trailer Tire Pressure Monitor System, supports GM's wireless trailer tire pressure monitoring sensors.
You can see real-time pressure and temperature readings for up to six trailer tires displayed in the cab.
These sensors are typically included as part of an option package or available as a genuine GM accessory.
So you'll need to install them on your trailer tires and then pair them with your truck's system, which usually involves a specific learn procedure.
