When temperatures drop, tire pressures often drop due to a change in air density.

Driving on underinflated tires can have serious consequences. According to Edmunds.com, underinflated tires can result in a blowout while you're driving, which can put you at risk for a serious auto accident. Underinflated tires can also cost you money. Tires also wear out more quickly when they are underinflated, causing you to have to replace your tires more often. To make sure your tires are properly inflated, make sure you check your tire pressure regularly.
