LANHAM, Md. (CBSDC) — AAA Mid-Atlantic is reminding drivers to be aware of their tire pressure as temperatures fall this winter.

With the blast of winter weather the D.C. region received this past week, AAA received more than 4,000 flat tire calls. Cold weather can cause tires to become under inflated, more so for cars parked outside all night than those kept in a garage.

AAA reports, on average, that the estimated annual number of highway fatalities caused by under-inflated tires is 660 people per year.

About 70 percent of the vehicles on the road have at least one tire that is either over or under inflated by more than 10 percent, according to AAA.

Proper tire pressure levels can be found in the owner’s manual or on a sticker that can be found on the driver-side door jamb. AAA says the pressure levels on some cars are different for the front and rear tires.

“Check the tread depth on each tire by placing a quarter upside down in the tread grooves. If the top of Washington’s head is exposed at any point, it’s time to start shopping for new tires. Also, look for uneven tire wear when checking the tread, the auto club advises. This can be an indication of suspension, wheel balance or alignment problems that need to be addressed,” AAA advises.

With a wintry mix making a return to the D.C. region again Saturday, AAA has a step-by-step video that shows how to prepare for and repair or replace a flat tire:
