Just wondering if it is possible to have the settings changed on the TPMS. My new truck wants 80lbs. and I don't, and the messages really get on my nerves.

 

Probably the dealer has to reprogram the system, unless there is a tuner out there that can do it.

 

80 psi seems really high for a pickup tire, all mine have a much lower maximum safe operating pressure rating.

 

80psi would be an E rated tire - normally you see them on 3/4 or 1 tons.


Hopefully he switched to a rim that was rated for the extra weight that an E rated tire can carry.

 

There has been talk on other forums that dealers cannot change this. I cannot confirm this myself as my 2013 has a button to change between the low pressure setting as well as the high setting at 80 psi.

 

I dont know about changing the TPMS but I recently had a similar conversation with a dealer mechanic.
Just yesterday I had new tires put on my 2012 1500 QC 5.7 Hemi 4x4 Outdoorsman.
The truck had E rated tires from the factory and I replaced them with an E rated tire. The door jamb lists the tires as LT 265 70 17 E and recommends 42 lbs.
The E rated tires will hold UP TO 80 lbs but you don't run with that much on an everyday basis.
If you are towing you up the pressure.
The recommended tire pressure is where the TPMS is set. So my E rated tires at 42 lbs never gave a code and never had an issue. And it is the same with the new ones.
I considered a P rated tire instead of the LT. The P rated tire is a max inflation of somewhere around 38 lbs depending on tire brand and a few other things. But that would set off the TPMS and to get the pressure up high enough to satisfy the TPMS would be running the tire at its max pressure all the time. And it would ride awful.
