- An estimated 32 million cars and trucks in the U.S. have at least two tires that are underinflated. If these were properly inflated, it would result in saving of nearly 560 million gallons of gas each year, which equates to more than $777 million. For an individual, that’s an estimated savings of 19 gallons, or $30 per year.
- Proper tire inflation pressure is the specified air pressure given by the carmaker for a certain tire on a certain car.
- Each car’s tire pressure differs and can differ even still between front and back tires.
- Correct tire pressure is critical for good fuel economy, safety, maximum tire life, and proper vehicle handling performance.
- One of the best time investments you can make is to check your tire pressure at least once a month to get the maximum life out of your tires.
- Check tire pressure more often in the winter because for every 10 degree drop in temperature, tire pressure decreases by one pound.
- Americans waste two million gallons of gas each year because our tires are underinflated.
- Gas mileage drops about 1% for every pound of tire pressure below recommended level.
- Over-inflation can lead to handling problems and uneven wear on tires.
- Keep an accurate tire pressure gauge in your car and check tire pressure when tires are cold. Tires heat up while driving. Warm tires will have a higher air pressure than cold tires. Air pressure recommendations are based on air pressure in cold tires.
- Never trust the appearance of a tire as a gauge for inflation.
- Check owner’s manual for recommended tire pressure or sometimes it’s located on the inflation sticker on the door jamb.
- Don’t forget to check the spare too!
