Hey everyone, new guy here,just found this forum and looks interesting.Tried searching for answer to this question but no luck. I have an 08 sierra 1500 bought new,my second one and first vehicle with TPI system. Just recently put a second set of tires on it and that's when the problem started. The new tires need 55lbs not the 35 that were OEM.Tried to reset the system per manual and it works for awhile then I get a warning to check all tires, apparently that procedure does not let the system relearn a new pressure value just a new position.Took it to my dealer and their telling me the pressure can not be reset.So I guess I have two questions,one is the dealer giving me the right info and if that's the case,is there anyway to turn off the warning system off so I can drive it like every other truck I've driven for the last 40 years,LOL
