Proper Tire Pressure for Winter
You can’t always tell if your tires are losing air just by looking. Slippery roads and icy precipitation aren’t the only winter driving danger. The changes in your tire pressure can significantly affect the safety and efficiency of your vehicle.
All gases contract and become denser during colder temperatures, and the air in your tires is no different. In fact, for every 10 degree Fahrenheit drop in temperature, the pressure in your tires drops by 1 lb. per square inch. In addition, tires lose 1 lb. naturally every month.
