Does the tire pressure light go off with a spare?
Here’s what you need to know: The spare tire is not equipped with a TPMS sensor, so the TPMS light on the dash comes on because it cannot get a reading from that tire. The light will stay on until you have the normal wheel replaced. This will go away after you have the regular wheel reinstalled on the car.
Can I drive with a tire pressure of 25?
If you have standard passenger tires (ninety percent of vehicles do) the lowest tire pressure you can generally drive with is 20 pounds per square inch (PSI). Anything under 20 PSI is considered a flat tire, and puts you at risk for a potentially devastating blowout.

What to do if your tire pressure is below 25%?
Alternatively, go to the tire shop and determine the air pressure. If your tire pressure is below 25 % of the recommended pressure, the lights will illuminate. Cold weather may compromise the tire pressure. As you take a short drive, the tires may heat up and restore the pressure.
