Dunno if it was the cold, but my tpms light went on-then I checked 'em cold. 2 were at 33 psi and 2 at 32 psi-I have 18" oem's for my current winter setup-my q is: is that enough of a drop to have the sensor go off-is it that sensitive?
I had a set of 4 sensors put on at the dealer-so it can't be b/c the sensors aren't on (unless the dealer didn;t install them). Any suggestions besides filling up to 35 psi all around if the light doesn't turn off?

 

Shouldn't OEM's be 35 psi?.. and I thought the warning came on below 30.

doulble check your pressures and see at what pressure the warning is activated. If it's still above 30, have the dealer check and adjust the system for you.

Mines coming on a 32-33 psi as well. It's pissing me off.

 

i didnt check but the temp dropped suddenly here, from maybe 80-90 to like 60-70. i think my light went on at 32. anyway i just aired back to 34-35 and all is well again
