Just for my own information, are the TPM systems built into the latest vehicles user adjustable? I have heard that the OEM setpoint is based on the manufacturers recommended tire pressures. As the majority of us agree, to run an empty truck with 80psi in the rear tires is dangerous (I run at 50 psi), which means that the TPM will always show an alarm condition therefore providing me with no indication if pressures are below 50 psi.
I see that there are aftermarket TPM systems that enable the user to adjust the set point. For those of us that tow 5th wheels, it would seem that the OEM TPM system is useless.
I understand that the OEM system can be adjusted by your friendly GM dealer who has the necessry tools and equipment, namely a Tech II. So when trailering, it is no problem! After arriving at the campsite uncouple the trailer, go to the nearest GM dealer, deflate the tires to 50 psi, pay the dealer $90 to reset the setpoint. Before leaving the campsite, go back to the dealer, inflate the tires to the towing pressure and pay him another $90 to reset the setpoint again.
On a six week trip to Arizona from the frozen North, we stay at about 12 different sites, thus the cost would be about $2000 in dealer fees. Cheaper to buy your own Tech II, even cheaper to buy an aftermarket adjustable TPM system.
