Abstract: The crown of a radial tire designed for high speeds has two lateral portions and a center portion, the lateral portions being narrower and more rigid than the center portion. The tire tread comprises, starting at the edges and proceeding towards the center: (a) two circumferential lateral ridges cut over their entire width by transverse grooves, (b) two circumferential lateral grooves substantially centered on the median lines of the comparatively rigid lateral portions of the crown, (c) two circumferential intermediate ridges substantially centered on the lines of junction of the comparatively rigid lateral portions and the less rigid center portion of the crown, (d) two circumferential center grooves, and (e) one circumferential center ridge at least as wide as the intermediate ridges.
