Tire Inflation Tips for Better Fuel Economy, Safety and Longer-Lasting Tires

Tire Inflation Tips for Better Fuel Economy, Safety, and Longer-Lasting Tires

Tire pressure is very important, but many owners don’t give a second thought to their tires after they’re installed. By regularly following a few simple tire inflation tips, you won’t be caught off guard when your car’s tire pressure warning light comes on or you experience a blowout.

Underinflated tires can cause a number of significant problems, including:

  • Decreased fuel economy
  • Abnormal tire wear
  • Poor traction, especially when braking and cornering
  • Tire overheating, which can lead to blowouts

According to the National Highway Traffic Safety Administration (NHTSA),”there was an issue with a tire before the crash occurred in 1 of 11 crashes,” including underinflation and blowouts. Also, the U.S. Department of Energy estimates that, for every one psi beneath specification, the average car loses about 0.3 percent fuel economy.

Proper tire pressure will ensure that you get the maximum mileage out of your tires, too. Some tires may last up to 60,000 miles, but underinflated tires could become unusable after only 20,000 miles.

Tire Inflation Tips for a Safe and Economical Ride

1. Using a tire pressure gauge

Begin by taking the tire valve cap off of the valve stem. If you have steel wheels and wheel covers, you may have to remove the wheel cover for access to the valve. Then, align the opening of the tire pressure gauge with the tip of the valve stem and press firmly. You may hear a short hiss of air; if the air keeps hissing, you haven’t quite aligned the gauge to the valve stem. Try again at a slightly different angle until you get it right.

With the gauge in place, read the pressure. Depending on their design, some gauges retain the pressure reading even after removing it from the valve stem, which can be a helpful feature if the tire is in an awkward position.

2. How much air is enough?

Think again before inflating your tires to the maximum PSI indicated on the tire sidewall; this is not the correct pressure specification. Instead, look for the “Tire and Loading Information” sticker, located on the driver’s door or door jamb.

You should be able to find this information in your owner’s manual, which you should keep in the glove box with your shiny new tire pressure gauge.

3. When to check and adjust tire pressure

Given that tire pressure changes with temperature, usage, time and damage, the NHTSA recommends that drivers check pressure levels at least once a month. Tire inflation should always be checked and adjusted when the tires are “cold,” or when they haven’t been driven in at least three hours. First thing in the morning is usually the best time to check.

Following these tire inflation tips will probably be the cheapest maintenance you can do on your own car, takes just a few minutes and doesn’t require a high level of expertise. Why not try and fit tire pressure checking into your monthly car maintenance routine?
