Why do tires go down in cold weather?

With the onset of winter, many drivers notice a low tire pressure warning indicator on the dashboard or see the tires look more flat than normal. The main reason is a decrease in temperature, which causes the air to become denser and the tire pressure to decrease. Over time, a decrease in pressure can lead to tire damage.

Tire Pressure Monitoring Systems (TPMS) significantly improve safety and driving comfort. Since September 2007, all new cars are required to be equipped with TPMS. This system alerts the driver to low tire air pressure using an indicator on the dashboard, allowing timely action to be taken.

How to maintain optimal tire pressure in winter?

When the temperature drops by every 10 ° F, the tire pressure decreases by about 1 psi. If the pressure indicator signals a low level in the morning, this does not necessarily mean that the tire is damaged. It is simply necessary to check and inflate the tires to the recommended level. Even if the indicator goes out after the tires warm up, it is recommended to use a pressure gauge to check.

For ease of control and maintenance of tire pressure, the use of a portable car pump will be an excellent solution. Modern pumps not only help to quickly inflate tires, but also are equipped with a pressure measurement function, which allows the owner to know exactly the condition of the tires and pump them up in a timely manner.
