Abstract: Run-flat tires having a sidewall support that is manufactured from particular rubber composition. These compositions are based upon a cross-linkable elastomer composition having, per 100 parts by weight of rubber, a polybutadiene rubber having a Mooney viscosity of between 55 and 85 and a low-surface area, high-structure carbon black. An additional second rubber component may also be included in the elastomer composition. The low-surface area, high-structure carbon black may be characterized as having a nitrogen surface area of between 15 m2/g and 25 m2/g and a COAN of between 65 ml/100 g and 85 ml/100 g.

Abstract: Particular embodiments include run-flat tires having sidewall supports that are manufactured from a rubber composition that is based upon a tin end-functionalized polybutadiene rubber as well as an additional second rubber component and a mixture of carbon blacks. The first carbon black may be characterized as being a low-surface area, high-structure carbon black and the second carbon black may be characterized as a low-surface area carbon black. The low-surface area, high-structure carbon black may be added to the rubber composition in an amount that provides a modulus of elongation at 10% measured at 23° C. of between 8 MPa and 10 MPa.
