How to fix a tire valve stem ？

Choose a tire valve that suits your tire specifications and usage needs. Generally, there are rubber tire valves and metal tire valves. Metal tire valves are usually more durable and can better resist the influence of external factors, thus providing a good foundation for fixation.

When installing a new tire valve, be sure to tightly fit its threaded part with the mounting hole on the tire hub. Use the valve installation tool and rotate it clockwise to ensure that the tire valve is firmly installed on the hub to avoid loosening.

For tire valves with nuts, you can tighten the nuts appropriately after installation to increase the stability of the fixation. But be careful not to over-tighten to avoid damaging the tire valve or hub.

Here are the steps to replace the tire valve:

1. Prepare tools

You need to prepare tire valve removal tools, new tire valves, detergent water (for detecting air leakage), etc.

2. Determine the type of tire valve

Different vehicles may use different types of tire valves, such as rubber tire valves, metal tire valves, etc. Understand the type of tire valves on your vehicle so that you can choose a suitable new tire valve for replacement.

3. Remove the old tire valve

First, let the tire release some air to reduce the air pressure in the tire, which is convenient for subsequent operations.

Use the tire valve removal tool to clamp the old tire valve.

Rotate the removal tool counterclockwise to unscrew the old valve from the wheel hub.

4. Clean the installation area

Use a clean cloth to wipe the area on the wheel hub where the tire valve is installed to remove dust, dirt and other impurities.

Check whether the installation hole is damaged or deformed. If there is a problem, it needs to be dealt with in time.

5. Install the new tire valve

Apply a little tire-specific sealant to the threaded part of the new tire valve to increase the sealing.

Insert the new tire valve into the mounting hole on the wheel hub and tighten it clockwise. Make sure the tire valve is firmly installed and will not loosen.

6. Check for air leakage

Use an air pump to inflate the tire to the appropriate air pressure.

Apply some detergent water around the valve and observe whether bubbles are generated. If there are bubbles, it means there is a leak and you need to reinstall or check whether the valve is damaged.
