TPMS limit

[Viking Truck]

I noticed some strange alerts with TPMS today and am wondering if anyone has been successful in lowering the threshold for alerts. Does that take dealer cooperation? This is not a discussion about how much pressure I should be running in my truck tires. Only one opinion is relevant there.

Today as I drove I took these three pictures of the TPMS display as I was driving and the tires were getting warmer, increasing pressure. In the first pic 56 psi is ok for drivers rear and 55 is not ok for passenger rear. In the second pic 56 is still not enough for the passenger side but fine for driver. In the third pic now 57 is not even enough for the passenger side but before 56 was fine for driver side.

Yes, I reprogrammed the low limit on both HD's.

But I don't believe that is your problem. I don't have any idea what to say, but maybe a bad sensor? But it seems to be working. I'm clueless, sorry.

How did you lower the limit? I can live with these quirks but I would like to lower the limit to keep the lights off. I dont often need the cargo capacity that the door sill sticker applies to.

I agree. 80psi is too much, empty.

I used this, just the '23 version...

My truck was fine when running 43PSI, then following the most recent update, it complains about low pressure; so annoying. Can the dealer reprogram it? I'm not a cheapskate but $220 seems high; I don't grow enough corn like you @gemarsh

 

[gemarsh]

When you reprogram the truck, it also reprograms onstar/gmc app. Which I find odd, but whatever. I haven't taken them in for service, so I don't know what would be said. Probably nothing but to fill the tires up to basketball bounce!

Notoriously inaccurate use a good manual tire gauge.

My dashboard TP is pretty accurate and consistent, especially when cold and readings compare to an external TP guage. A change in tire pressure can take a while to permeate via tpms to the dashboard.
