  • Low noise run-flat tires
    Patent number: 8746302
    Abstract: A tire includes a pair of sidewalls in spaced apart relation and extending substantially radially from a respective inner circumferential portion to a respective outer circumferential portion, a tread extending between and connecting outer circumferential portions of the sidewalls, at least a portion of a tire cavity defined by the tread and sidewalls, and a bead portion on the inner circumferential portion of each radially extending sidewall, the bead portion providing an engagement surface for engaging a wheel on which the tire is to be mounted, and a noise reducing foam disposed in at least a portion of the tire cavity.
