Tire valve check

Unscrew the dust cap from the tire valve.

Apply a little soapy water to the valve. If a soap bubble forms, close the valve by turning the protective cap.

Attention! Only metal protective caps are used to tighten the valves.

Check the valve again. If a soap bubble forms again and the valve cannot be tightened any further, replace it.

Be sure to screw the protective cap back on.
