991.2 GTS
had to get the rears replaced this week and the orange tire warning light won’t go away. The TPMS keeps doing the “measurement runs”. After two days and about 50-60 miles of driving, I deflated my rears down to 38psi cold and fronts at 33psi, I set it to “comfort” setting and marked it as a “partial”. Have driven about 10 miles with that but still can’t get rid of the message. Any ideas?
I don’t drive 165mph so that’s not a concern.
My previous pressures were 40/34 and that served me just fine.

 

Maybe switch to winter partial and see if it gets a reading. Then switch to summer partial. And then ultimately to whatever you want.

TPMS batteries do die after a while...

 

Go back to the tire place and they can see if all the sensors are broadcasting with their little handheld device.
