Denali with max trailering package

[Samuel Ross]

I just picked up a new 2021 Denali with max tow package. I see that it is capable of monitoring the trailer tire pressures but does anyone know how it works? I cannot seem to find any information on the system. Do I need special caps on the valve stems? or do the wheels need TPMS installed?

Thank you, this site has been very helpful

I have no idea but that's a super cool feature I'm interested in knowing how it works too!

Look in the glove box -- pretty sure there should be some sensors for the trailor.

Correct and then check the manual for how to set them up.

Correct, your vehicle should have come with the sensors and you would need to get them installed on your trailer. If not you can buy them from the dealer or online.

The sensors don't come with max trailering, they are $50 though if ordered with the vehicle, else it is $150 for 2 trailer tires.

Ah okay! Seems like my dealer added them in there for $50 when we put the order in. Just confirmed it on the order sheet they gave me. Good thing they followed through and put them in the glove box!

I'd probably shop around and check for used too. Looks like it is the same for 2019-2021. $75 per sensor is kinda high and I am not paying that for my small trailer when the trailer was only $500.

$114 for 2 sensors isn't bad with the coupon code and GMC points. Still would like to get it a little lower.
