Exterior surface of tire sidewalls have protuberances alternating with voids. The protuberances are arranged between points A, B and C, D. Point A is at the intersection of the radially exterior surface of the tire tread and of the sidewall. Radial axis ZZ′ is distant from equatorial plane AA′ by length LA of between ½ (L−20 mm) and ½ (L−80 mm), L being the external section width. Point B is at a radius greater than or equal to [R1+0.1 (RA−R1)] and less than RA, R1 being the radius at the external section width and RA being the radius at the point A. Point C is at a radius less than or equal to [R1−0.1(R1−R2)], R2 being the radius of the top of the rim flange. Point D is at a radius in the range R2
