Yet, one in four cars has at least one significantly underinflated tire - a major safety risk and a big drain on your gas mileage.
"Underinflated tires contribute to thousands of crash-related injuries each year. Not only can they lead to blow-outs, they can also negatively affect your car's handlin," said Jon Linkov of Consumer Reports. "Underinflated tires also waste fuel and they wear out a lot faster."
To make it easier to check tire pressure, Consumer Reports tested 14 gauges - costing anywhere from $4 to $56.
The digital Accutire gauge for $10 is one of the top-rated.
"You want to make sure that you have the correct recommended tire pressure. A common mistake is going by the tire pressure listed on the tire. That's actually the pressure for the car's maximum carrying load," said Linkov.
So, look for a sticker on the driver's-side door or consult your owner's manual and check tires when they're cold - not just after driving on them.
