I have a 2021 Dodge Diesel 2500. Is there a way to reduce tire pressure gauge from 80 psi to 55 psi??

 

Let air out of the tire?

Or does that cause the tire monitors to whine?

 

Tire monitors whine.

 

Some trucks were sold with a Light Load switch on the dash, by 2021 im not sure if it would have a switch anymore or just be built into the radio if you have a higher package, or possibly built into the instrument cluster, and consult of the operators manual may provide some information
