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 DEG C of between 8 MPa and 10 MPa.
