Abstract
A tire for a heavy vehicle having beads, sidewalls and a crown, the crown having a reinforcement armature formed of at least two working plies, is provided with a protuberance for deflecting sprays. To deflect the flow of water ejected laterally by this tire during travel on water-covered ground, without adversely affecting the thermal level of said tire, provision is made to arrange on at least one of the sidewalls a protuberance which is limited by an upper wall radially to the outside and a lower, wall radially to the inside, the intersection of said walls being along a line joining points C which are located axially farthest to the outside of said protuberance, the angle &agr; between the axial direction and a straight line tangent both to the edge of the tread and to the protuberance being less than 45°. Furthermore, the upper profile of the protuberance intersects the sidewall profile at a point K located within the extension of the average profile of the radially outermost crown ply.
