1. A tire comprising; a carcass reinforcement surmounted by a crown reinforcement, itself capped by a tread, the tread being connected to two beads via two sidewalls each having an exterior surface, at least one of the sidewalls comprising at least two circumferential protrusions, each sidewall comprising an equator point situated on the exterior surface of the sidewall radially at the same position as the axially outermost point of the carcass reinforcement in an unladen reference configuration, each circumferential protrusion being bounded by; a planar radially upper wall, a curved radially lower wall, and a connecting wall situated between the planar radially upper wall and the curved radially lower wall, wherein, for each circumferential protrusion: the connecting wall is substantially parallel to the carcass reinforcement considered axially facing the connecting wall, the planar radially upper wall is inclined relative to the radial direction, at least a portion of the curved radially lower wall is substantially parallel to the radial direction, the radially upper wall and curved radially lower wall are asymmetrically configured with respect to one another in the radial direction, the height (H) of each circumferential protrusion, measured in a direction substantially perpendicular to the carcass reinforcement from the exterior surface is greater than the smaller value of 0.8 times the total thickness (T) of the sidewall as measured at the equator (E) and 4 mm, and less than the greater value of 1.6 times the total thickness (T) and 8 mm, in the meridian plane at the center of the contact patch of the tire in a compressed configuration, an angle α formed by the planar radially upper wall with the radial direction is, in the case of the radially outermost protrusion, greater than 95°, and the radially innermost position of the connecting wall of the radially innermost protrusion is situated radially on the outside of the equator point (E).
