Invisible tire valves

Invisible tire valves are different in design from traditional tire valves. An inflator stem is not used; instead, a removable cap on a valve stem embedded in the tire rim is fitted, with only the cap visible. When inflating the tire, the cap is first removed, typically with a coin, and then a "portable" dedicated inflator stem is screwed onto the valve stem. Through the inflator the tire is inflated as usual.

Recent designs simplify use with some caps designed to be removed by the inflator stem itself, instead of a coin.

Function

Invisible valves are simple in appearance, and by removing the inflator stem can improve the balance of whole tire. Currently invisible tire valves are popular in Europe.
