How Much Air is in that Tire? It looks a little low.

Now that we have had a few good winter storms and colder temperatures for a couple of months it is a good time to check the tire pressure in our tires. Many newer vehicles come equipped with a Tire Pressure Monitoring System that checks the tire pressure automatically. Some TPMS will only notify you if there is a significant difference in air pressure in different tires. If all tires lose pressure at the same rate the system will not offer a warning.

For vehicles without Tire Pressure Monitoring Systems or if sensors were not installed in a  Winter Tire Package an air gauge is the only way to know if your tires are properly inflated.  We may have let the tire pressure checking slip because it's been so cold out!  Well now is the time to get the air gauge out and check things over.

Typically a tire will lose 1psi of pressure a month however when the temperature drops they will lose even more depending how cold the temperature is. Your tires will lose about 1 psi per 10 degree drop in temperature.   The best time to check tire pressure is first thing in the morning, however if have pulled the car in the garage I could recommend putting a 2-3 extra psi to compensate for the higher temperature in the garage.
