Tubeless tires use a valve attached to the wheel to control air pressure. The valve provides an inlet to add air and an outlet to relieve air pressure in the tire. The valve stems are inserted into a hole in the wheel rim designed for the stem. Usually, the hole is threaded and the stem screws into the hole. The stem could also be retained with a threaded nut, depending on the valve model. If there is no threaded nut, it is the pressure in the tire that keeps the valve in place. There will be a rubber grommet between the valve and the wheel to seal the connection.

Deflate the tire. The tire must be deflated before proceeding with valve removal for safety reasons and because the air pressure will prevent the valve removal.
Separate the tire from the rim. The tire does not need to be removed, but it needs to be moved over enough to access the inner side of the valve.
Use a wrench to unscrew the retaining nut, if there is one on the valve. Many valves do not have a retaining nut, but some do.
Push the valve inward into the tire area of the wheel rim, if it is not a threaded hole. If the valve does not push in easily, use a lubricant like dish soap to loosen the connection. Do not use an oil-based lubricant because residue can break down the rubber grommet used to seal the connection. If the valve is not being reused, a gentle tapping on the valve tip with a hammer can loosen the valve. Do not hammer any harder than gently because you can cause damage to the wheel rim.
Unscrew the valve, if it is mounted in a threaded valve hole. If the valve is not being reused, use a pair of pliers to unscrew the valve. Otherwise, use a valve stem tool to connect to the valve and unscrew it from the valve hole. Push the valve inward into the tire area of the wheel rim once the valve is fully unscrewed.
Remove the valve once it has been pushed into the tire area of the wheel. If replacing the valve, check if it is a low-pressure or high-pressure valve and use the same type of replacement valve.
Tips and warnings
- Check if the vehicle is equipped with valve-mounted tire pressure monitoring sensors (TPMS) before removing the valve. If the vehicle has TPMS, dismount the wheel and fully remove the tire before removing the valve.
