I am trying to find out if my 2020 Silverado High Country dually was supposed to come with trailer TPMS sensors. I have seen posts on other forums that say yes and no.

 

My 2019 LT Z71 came with them. I wouldn't see why a High Country wouldn't come with them! Heck, for those prices, they should throw in a lifetime supply! Contact your dealer to be sure.

 

thought tpms was mandated in the states.

 

The OP was referring to the extra set of four TPMS that came with my truck that are to be used in a trailer if you tow one. Mine were in a plastic bag in the lower glove box. I have not used them yet but I suspect they are already paired to the truck system.
