Ninebot Max Replace Valve Stem

If your tire no longer holds air and a soap bubble test leads you to believe it is caused by a torn valve stem, this page will show you how to replace it.

Begin by removing the valve stem cap (if it is still present), then press the center core to remove as much remaining air as possible.

Once you've done this, use tire irons to push down hard on the tire and get one under the rim near the center of the valve stem.

The tire still on the rim. You will need to debead the tire in order to access the valve stem and replace it.
