How is the valve of the vacuum tire installed

It comes out from the hub, and the small head goes through the inside, and is pulled with pliers.

There is a circular ring groove at the back so that the base will snap onto the circle of the hub.

It is not necessary to remove the tire to install the valve.

The air can be released at the position where the valve is installed to depress the tire.

Expose the nozzle base.

Cut off the base of the original air nozzle, and pull out the air nozzle.

It can be replaced.
