With properly inflated tires...
  1. Americans could save 4 million gallons of gas each day.
  2. Americans could save hundreds of dollars each year on gas and extend the life of their tires by 25%.
  3. Americans could all breathe cleaner air because we?d be burning less gas.
  4. Americans would be able to protect the Arctic National Wildlife Refuge forever!
How To:

Always use the inflation recommended by the vehicle manufacturer. You can find this information in several places; in your car owner's manual, on the inside of the glove box door or posted on the edge of the driver side door.

Use a reliable gauge. This is very important!

For those of you who have radial tires, they are supposed to have a slight bulge in the sidewall at their proper inflation pressure.

Make sure to check your tire pressure every month and especially before a long trip or pulling a heavy load.

To get a true tire pressure reading, check the tires when they?re cold ? when your vehicle has been idle for at least three hours.
