Rubber composition suitable in vulcanised state as safety support for tyre and such a support

摘要

Rubber composition useful for producing a vulcanized safety support for mounting on the inside of the side wall of a pneumatic tire comprises, per 100 parts by weight (pbw) diene elastomer(s): at least 60 pbw natural rubber or synthetic polyisoprene, more than 60 pbw white reinforcing filler and 3-8 pbw sulfur. Independent claims are also included for the following: (1) a safety support that is made from the rubber composition and is designed to be mounted on the inside of the side wall of a pneumatic tire so as to support the tire tread in the event of a drop in inflation pressure; (3) a tire including the safety support.
