service tps...?
It's a fact that temperature affects pressure.
For every 10degrees drop in temperature, pressure drops 1psi.
I learned many years ago to raise my tire pressure to 38psi, and I never had a tpms light on during the winter since.
I check my tires when it is warm outside, so I do not recommend setting the pressure to 38psi when it is below freezing.
example: @70degrees 38psi
that same 38psi will be at 31psi @0 degrees
if you set to 38psi at 0 degrees then your tires pressure will go to 45psi at 70degrees.
tps stem is metal.
