PROBLEM TO BE SOLVED: To provide a rubber composition for reinforcing sidewall sections improved in heat resistance and to provide a run flat tire with improved durability. SOLUTION: The rubber composition for reinforcing the sidewall sections has≤3.0 MPa dropping value of the dynamic storage elastic modulus ranging from 170°C to 200°C. While, the run flat tire is reinforced by reinforcing layers in the sidewall sections and the rubber composition is used in the rubber reinforcing layers. COPYRIGHT: (C)2010,JPO&INPIT |
