Why does my tire pressure go up by itself?
As temperature levels change, so does the air pressure in your tires. It’s the same as when you drive at higher speeds for an extended period: the tire warms, and the air within expands and increases pressure. Once you start driving and the tires heat up, pushing the pressure above the threshold, the light will go out.
