How to Check and Maintain Proper Tire Air Pressure

Maintenance of proper air pressure can extend the life of your tires. It helps your tires retain traction with the road, even in adverse conditions, and can increase the fuel economy of your vehicle, so you can drive farther on the same amount of gas. Keep a few basic tips in mind as you regularly check the inflation of your tires.

Things You'll Need:
  • Pressure Gauge
  • Air Compressor

Step 1:

Check the inflation in the morning, before the car is driven and while the tires are cool. Set the pressure according to the vehicle manufacturer's recommended cold-tire pressure.

Step 2:

Adjust the pressure for extra-cool conditions. If the car has been parked in shade for many hours, check the pressure using the gauge and adjust the pressure higher by two pounds per square inch, or PSI.

Step 3:

Adjust the PSI to account for the amount of time you have driven the vehicle within the previous three hours. When driving short distances or speeds less than 45 miles per hour, set the pressure four PSI higher than the recommended cold inflation pressure. When driving for long distances, set the pressure six PSI higher than the manufacturer's recommended cold inflation pressure.


Tips:

Most tire pressure gauges have a stem on the back side. This stem can be pressed into the tire's valve stem to release air, in the event that you have added too much pressure.
