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.
