Alligator TPMS Sensor Covers Next-Gen GM Pickups

Order Reprints

Alligator RS universal TPMS sensors now cover the all-new, next-gen GM pickup trucks.

Alligator RS universal tire pressure monitoring systems (TPMS) sensors now cover the next-gen General Motors (GM) pickups -- 1/2 ton (2019-21 Chevy Silverado 1500 and 2019-21 GMC Sierra 1500) and heavy-duty (2020-21 Chevy Silverado 2500/3500 and 2020-21 GMC Sierra 2500/3500).

GM trucks have always used 315 MHz sensors, but the new models come equipped with 433 MHz parts and also have a feature that's new to the pickups: tire-fill assist.

The tire fill alert system indicates via audial and visual cues when a tire is being inflated. When filling a tire, the turn signal will flash on the corner that is being filled and inform the driver that the optimal tire pressure has been reached during inflation by sounding a single horn chirp. If the tire is accidentally over-inflated, the vehicle will sound three successive horn chirps.
