Tire Sensor

[Tukozin]

This morning when I was getting in the Jeep, it was 37F at 620 and my tire sensor light appeared.
Should I air up my tires more, or change my tpsm?

Any thoughts?

Well since it’s cold your pressure is naturally going to be lower now that the air is more dense. Factory has the sensors set at 28psi (or there about) for the light to come on. Just check your pressures and make sure they are where you want them to be set at.

Gotcha, I'll do that when I get off work. Would it be a problem if I air my tires 5 more PSI? Since it's going to be colder now due to fall (we got winter like season up here).

I’m pretty sure the factory is set to 35. The lower the go the more it will come on when it gets cold.

The sidewall of the tire shows the maximum recommended inflation pressure, which is usually around 45 psi i think. Just keep it below that value by 5-10 psi for safety, and above the 35 psi TPMS limit. I usually need to top off the pressures going into the winter months up north, and i vent a little pressure going to the texas summer heat.

Better advice than this ☝️would be for the OP to find out what is the right pressure for his rig. The above post is just bad advice, IMHO

Chalk test your tires to find out what is right, and run that for maximum tread life as well as maximum traction on the highway.

Here is a good thread to read up on.

Yes factory setting is 35 psi but the Lowest setting for when the tpms light comes on is 28 psi I believe.

Set them to pressure at what ever temperature you are at, if it calls for 35, do 35 whether it’s 90° or -25°

Also, like above - set the pressure for even wear across the tread of the tire (realizing they will need more air if you add weight). If your correct pressure is close to, or below, 28# get a programmer to lower the tpms set points

Good point. This is definitely a better approach. I learned something new, so thank you!
