TPMS Sensor Warning

[Lockout888]

Have a 2008 Tahoe LS. Just got some new wheels, tires and TPMS sensors installed and my DIC is giving me a warning to check tire pressures.

DIC shows RF=36, LF=38, RR=38 and LR=39. I have checked the tires with a manual pressure gauge, and all the tires are between 38-40psi.

New tires are 305/40/22 and say maximum pressure is 44psi.

Any ideas?

It is possible that one of the new sensors is bad, I have variations of your tire pressure with no problems on my 2013 Yukon.

when you install new tires you have to "marry" them to the vehicle, it will not pick them up automatically, i have two sets of rims/tires and i get this every time i switch them around

My sensors were acting up, went back, they forgot to "reset" the sensors they said, not sure what that means, the guy came out with a remote control looking device, big as his palm, went next to each sensor and reset them. The warning msg went away. I hope it's something as easy as mine. Good luck
