Abstract: A tread for bonding to a tire carcass to form a retreaded tire having a length, a width, a top side and a bottom side. The tread also includes a central portion and a pair of wing portions extending laterally from the central portions. The top sides of each wing portion include one or more discontinuities having a longitudinal component and configured to resist deflection when subjected to a force from the bottom side and to deflect downwardly when subjected to a force from the top side. In particular embodiments, the one or more discontinuities are arranged within each wing portion are arranged within a thickened portion of each wing portion.

Abstract: A method for designing tires for reduced cavity noise is directed to tires of the type having architectural elements comprising at least one carcass structure anchored in each side of the tire in a bead, each bead having a base which is intended to be mounted on the tire's design mounting rim, a side wall portion extending radially upward from each bead, a reinforced summit comprising reinforcement cords disposed at a given angle, and the side wall portions joining the summit. The method includes the step of arranging the architectural elements to provide a flexibility level of at least a portion of the summit to allow said portion to vibrate at a frequency substantially corresponding to the cavity mode.

Abstract: A device for attenuating noise generated in a rolling tire and wheel assembly includes strips arranged as a circumferential ring in the tire/wheel cavity. The strips are spaced circumferentially to provide a profile of ridges and gaps in the ring. The rings may be placed on the interior surface of the tire or the wheel or both. Preferably, two rings are formed, and the gaps of the rings are in staggered relationship about the circumferential direction.
