GMC TPMS

Are those wheels and tires 17.5's? Just trying to understand how your set up requires 110 psi.

The wheels are 16," and are required to run at 110 psi per the manufacturer. I will probably just continue to use my aftermarket TPMS on the 5th wheel if I can't set them to the correct pressure in the truck.

Silliest thing I’ve heard in a while.
You really want your TPMS to alarm you at 109 psi? 1 psi under what you think it should be?

ROFL

I don’t know if they are the same system but on my 2009 we raced the truck and ran tire pressure as low as 20psi, I had the dealer reset the tire pressure settings in the TPMS so we wouldn’t get the dashboard warning.

Been the better part of 10 years since ANY dealer would adjust TPMS thresholds, on the books, at least. But there is aftermarket equipment that will.
However in the OPs case he doesn’t understand what he’s dealing with or he’d realize it’s a non issue in his case and he has a great solution already.

No, he does NOT want it setting off the alarm constantly because the tires are 10PSI over pressure.

Ohhhh, ok.... my bad.

I've only had about 15 or 20 GM's, Fords and Dodge/Rams 1/2 tons and 3/4 tons (1 tons have informational monitoring but no preset limits) in the last 15 years or so since 2008? when TMPS became mandatory and standard.

But NONE of them had an upper limit alert on the TPMS. Only a lower limit.

But ICBW, or maybe the trailer systems work differently?
