Abstract

A support (1) according to the invention comprises a rubber article. The support comprises: - a substantially cylindrical base (2) which conforms to the wheel rim wheel, -a substantially cylindrical crown (3) which comes into contact with the inside of the tire summit in the event of a drop in inflation pressure, but to leave a clearance relative to the summit at nominal inflation pressure, and -an annular body (4) connecting the base (2) to the crown (3). The rubber article comprises a rubber, preferably a mix of natural rubber and polybutadiene, a metal salt of a carboxylic acid, preferably zinc dimethacrylate, an effective amount of carbon black or silica, or both, and a peroxide for curing of said support. The support (1) of the present invention provides weight reduction, reduced hysteresis, enhanced thermal stability, and enhanced thermo-oxidative stability, therefore providing longer service life.
