So, let's say you check your tire pressure (on a cold tire, of course) in July, when it's 90 degrees out. It's 30 psi. If you check it again in January, when it's 20 degrees, your tire.

Why Does My Tire Pressure Light Come On When It's Cold Outside?

It is a scientifically proven fact that pressure varies about 3-4% points at every temperature variation of 10°C (18°F) inside the tire. To put it simple: if temperature goes up.

Measure the air pressure when tires are cold. This means the vehicle has been parked for at least three hours, or driven less than 1 mile (1.6 km). If necessary, add or release. As a rule of thumb, every 10°C rise or fall in temperature affects a tyre’s pressure by between 1 and 2 PSI. So, the change in your tyre pressure from summer to winter can be up to a 15%.

Colder temperatures will cause tire pressure to drop about 1 pound per square inch for every 10° F drop in air temperature. If you don’t fill up at home, the warning light may.

Increased heat means increased air pressure, while the opposite is true for the cold. Think back to the first cold day in the Fall, or even late Summer. Your TPMS light. Why Does Tire Pressure Change? When air molecules experience cold temperatures, they move slowly and stick closer together — taking up less physical space. In.
