Lower TPMS pressures on 2015 GM 2500HD???
 

Can you lower the TPMS threshold on the 2015 trucks and if so, how and how low???Factory is 60psi F and 70psi R which can be lowered by about 25% before the alarm goes off but it still rides like a dump truck..... When not towing I usually run about 45lbs or so. Having to reset the dash is a PITA with the lowered pressure. It goes off every few minutes and requires clearing or you can't change the radio, make calls, use NAV etc.

As a plan B, does anyone know if the TPM sensors need to show movement? If not, the work around like other vehicles is to remove the sensors and put them in your spare tire or pressurize a PVC tube and install the sensors in it at the appropriate PSI.

Someone must have done this already.... Any help would be greatly appreciated.....

Thanks

Yes sir, the dealer should be able to change the tire psi settings with the GDS2 no problem.

Thanks:

Yes as it turns out it comes down to whether or not the dealers wants to do it for you.....
