Tire pressure gauge

Tires normally lose some air in day-to-day use, and you may have to add a air periodically and usually it is not 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 leak as you begin and more will leak 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 see whether the tire pressure is low or high.

5. Adjust the tire pressure to the specified pressure. Refer to "Tires and wheels" section in chapter 2.

6. Reinstall the inflation valve cap.
