My understanding is that when the TPMS light is reset, it creates a new baseline depending on the current tire pressure.

 

This came up before, but I couldn't find the thread. The FSM didn't specify a specific change; it just indicated when checking the system, drop the psi (or raise it) 5-6psi from where it was previously set. The system reacts to a change in pressure, not just a drop. So the psi going up should trip it too.

I keep mine at 35psi. Mostly because I tow frequently enough, and don't want to change between 30-35 psi every-time.

 

Open driver door, you will see your PSI...I keep mine above their recommendation +2PSI cold

 

I checked the tires and they are all around 25 psi. Is 30 psi the baseline the sensors use?

My observation has been 28 PSI is the threshold. BTW, screw the factory label, and IMO go with 35 PSI.

In the case of my '13 there are two stickers, side-by-side, and they don't agree! I stick with 35 too. That is actually where the dealer set mine when we rolled off the lot.

 

You can set the pressure to what you want using the reset, then when it falls outside of that range, the light goes off.

 

That's why I drop my spare at least once a year to clean it and top it off with air.

 

Dropped the spare a couple of days ago when the light came on. Both it and driver's front tire were down to 25 psi. Temps went from being in the 60's to the 20's in about a week. That's my excuse for it anyway.

 

At 1 PSI per 10 degrees or air temp, your tires must have been around 29 PSI before the cold snap. Shame on you, man, for letting them get that low!
