CROSS REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation of application Ser. No. 09 / 501,408, filed Feb. 10, 2000, which claims priority under 35 U.S.C. § 119 from French Patent Application, No. 99 / 01766, filed Feb. 11, 1999, the disclosures of both of which are incorporated by reference herein in their entirety.SPECIFICATION

[0002] The present invention relates to the use of rubber compositions intended for the manufacture of tires as elastomeric internal filling compositions, also referred to as “cushion mixes”, in the bottom zone of a tire.

[0003] Radial-carcass tires for motor vehicles bearing heavy loads at greater or lesser speeds, in particular those for heavy vehicles, have a framework formed of reinforcements or plies of metal wires coated with elastomers. Such tires comprise in the bottom zone, one or more bead wires and a carcass reinforcement extending from one bead wire to the other and, at the crown, a crown reinforcement comprising two or more crown p...
