TPMS help

I have noticed on colder days (35 and below) my TPMS will kick on...sometimes. It's very inconsistent and usually after the car warms up and I put around 10 miles on it the warning light kicks off. Any ideas?

Tire pressure seems fine, stock wheels. Any help is appreciated.

When it's cold your pressure in ur tires gets less becasue the molecules are tight together after driving the tires warm up and heat up the molecules and they expand to put more pressure! What is ur pressure ur runningnow!.

I ran into this same problem and i upped my pressure like 2psi and never ran into this problem i'm at like 35 now if ur 32 psi put it up some and should never run into any problems!

Heat from driving a few minutes expands the air, raising the pressure back up above the threshold to turn the light off.

You should still add some air because of the cold days. in my opinion.

You want to have 32psi at the coldest possible ambient temperature. I'm actually running closer to the 34psi right now with it being between 20-40 degrees outside.

Remember every 10 degree drop in temp you lose 1psi.

on the cold side the tpms will kick on at 26 psi..

cold will set it off.. it it goes off when you drive it, your really need to check the pressure..
