Abstract:
A safety assembly (1) for a tire allowing running at reduced pressure. A rim (2) is equipped with a valve, and a tire (4) is mounted on the rim. A structural support (3) rests on the rim (2) and is enclosed in the space between the rim and the internal wall of the tire. The two axially opposed ends (31, 32) of the base (30) of the support (3) form an airtight joint with the part of the rim (2) on which they rest. The space between the rim (20) and the base of the support (30) and situated between the two airtight joints communicates with atmospheric pressure by means of a duct (26).
