How to adjust the air valve of minivan?

1. First, we need a barometer and an air nozzle tool to check the current air pressure of the tire with the barometer. The barometer has a contact that can be inserted into the gas nozzle to measure the air pressure. Make sure to determine the correct air pressure value.

2. Secondly, use the air nozzle tool to easily rotate the air nozzle cap and open it completely.

3. Then insert the contact of the barometer into the gas nozzle to ensure that the contact is closely connected with the gas nozzle. Observe the reading on the barometer. If the air pressure is lower than the required value, you can gently press the air nozzle with the needle or mouth on the air nozzle tool to release air slightly. If the air pressure is too high, you can gently press the air nozzle with the needle or mouth on the air nozzle tool to release air until the required air pressure is reached.

4. After finally adjusting the air pressure, measure it again with the barometer to ensure that the air pressure reaches the required value. Close the valve cover with the valve tool.
