Abstract:

A valve for a safety tire, the valve enabling air to be individually supplied to an inner air chamber and outer air chamber of a double structure tire and also enabling the air to be individually released from the chambers. In a first hollow stem (22) of a valve (20) are provided a hole (34) communicated with an inner air chamber (14) and a hole (35) communicated with an outer air chamber. The holes (34, 35) each have a valve core (41). A removal restriction adapter (105) is screwed in the hole (35), on the opposite side of a tire. The structure above makes it possible that air supply to and air release from the inner air chamber (14) and air supply to and air release from the outer air chamber (15) are individually performed with a simple structure.
