How to Check Tire Air Pressure

Maintaining proper tire pressure is a basic but often overlooked part of car maintenance. Properly inflated tires mean better vehicle performance, safety and fuel efficiency.

Checking and maintaining tire pressure is easy too. All that is needed to keep those tires rolling is a good air pressure gauge and an air source.

The first thing to track down is a tire air pressure gauge. These are available at auto part stores and most gas stations. Air pressure gauges come in a few varieties including dial gauges, digital gauges and the pen-like gauges most people are familiar with.

They all work equally well, so it really comes down to personal preference, but keep in mind that digital gauges need batteries.

Tire air pressure is measured in pounds per square inch, or PSI. Every tire has a recommended PSI level which is noted in raised letters on the side of the tire.

Typically, passenger car tires have a PSI level between 30 and 40. Larger tires, like those on trucks or vans, have higher PSI levels of around 45 or 50. It’s a good idea not to go five PSI above or below the manufacturer’s recommendation.

Both under-inflated and over-inflated tires wear out faster and are dangerous to drive on.

To get an accurate PSI reading, firmly press the tire air pressure gauge onto the valve stem on the side of the tire. Once the gauge is correctly pressed into the stem, air will stop escaping from the stem.

At this point, the air tire pressure gauge should provide an accurate reading of the tire pressure. If it is low, the tire needs more air. An air compressor, found at most gas stations, is necessary to inflate the tire.

When adding air to the tire, make sure to stop and recheck the pressure often to avoid over-inflating it.
