Alligator sens.it RS universal TPMS sensors now cover the all-new next-gen GM pick-up trucks – 1/2 ton (2019 and up Chevy Silverado 1500 and 2019 and up GMC Sierra 1500) and heavy-duty (2020 and up Chevy Silverado 2500/3500 and 2020 and up 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 pick-ups: tire-fill assist, a tire fill alert system that 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 overinflated, the vehicle will sound three successive horn chirps.
