With single-digit temperatures and below-zero wind chills expected to hit Michigan starting Thursday night, Jan. 22, some Michiganders may wake up to a low tire pressure warning light on their dash.
The reason, according to Consumers Reports, is due to the cold weather causing air to become denser, reducing the tire pressure.
Additionally, tires naturally lose pressure over time, which can lead to a low-pressure warning.
According to Consumer Reports, cold temperatures cause tire pressure to drop about 1 pound per square inch for every 10 degrees drop in air temperature.
How often should I check my tire pressure?
You should check your tire pressure at least once a month, according to the American Automobile Association (AAA).
Most modern vehicles have a tire pressure monitoring system that triggers an indicator light on the dash when pressure is significantly low. The systems also show the pressure in each individual tire, allowing you to pinpoint the issue.
What should I inflate my tires to?
The ideal tire pressure for most vehicles typically falls between 28 and 36 PSI, AAA says.
Specific air amounts can be found on the inside of the driver’s door. You also can check the owner’s manual for the correct PSI.
Avoid filling up your tires to the sidewall’s maximum unless you’re carrying a heavy load (and even then, be cautious).
How to inflate your tires
According to AAA, when inflating your tires, follow these steps:
