Tires normally lose some air in dayto-day use, and you may have to add a few pounds of air periodically and it is not usually a sign of a leaking tire, but of normal wear. Always check tire pressure when the tires are cold because tire pressure increases with temperature.

To check the tire pressure, take the following steps;

1. Unscrew the inflation valve cap that is located on the rim of the tire.

2. Press and hold the gauge against the tire valve. Some air will escape as you begin and more will escape if you don't press the gauge in firmly.

3. A firm non-leaking push will activate the gauge.

4. Read the tire pressure on the gauge to know whether the tire pressure is low or high.

5. Adjust the tire pressures to the specified pressure. Refer to More Details.

6. Reinstall the inflation valve cap.
