Poorly inflated tires reduce your fuel economy and cause premature wear. In fact, tires can lose up to 1 psi (pound per square inch) every month. Ideally, you should check all your tires, including your spare, once a month. Be sure to check them before any long road trips.
While many people are comfortable testing and adjusting their air pressure on their own, it can be intimidating if you’ve never learned. Here’s how to check your tire pressure in six steps*:
- Purchase a trusted tire pressure gauge.
- Remove the tire air valve end caps. (Put them somewhere so they don’t get lost.)
- Press the tire pressure gauge into the valve stem to get a reading.
- With a digital gauge, the reading should appear almost immediately
- With a pencil-style gauge, the indicator will pop out to show you the reading
- Be careful if using a gas station’s gauge connected to the air pump. These are notoriously abused and can often be inaccurate.
- Check the measured PSI reading. Compare that to the recommended PSI found in your owner’s manual or inside the driver’s door.
- Is the PSI above the recommended number? Let out some air and measure again.
- Is the PSI below the recommended number? Fill your tire with air. Remeasure and repeat until you get the right reading.
Always follow the placard on the inside of your car door for exact inflation instructions.
