PNEUMATIC REINFORCED FLANKS RESISTANT TO CHEMICAL ATTACKS

摘要

The invention relates to a tire for a wheel assembly comprising a rim and a tire, said tire comprising at least one carcass reinforcement (2) surmounted radially on the outside of a crown reinforcement (3), itself radially the interior of a tread (4) having two axially outermost ends, said crown reinforcement (3) consisting of at least one layer of reinforcing elements, said tread (4) being connected with two beads (5) via two sidewalls (6), said beads (5) being intended to come into contact with a rim (7) having rim hook tops (7b), each bead (5) having at least one circumferential reinforcing element, said sidewalls (6) having, on their outer surface, a series of alternating protuberances (8) with recesses (9), the protuberances (8) being arranged on the surface of the sidewall (6). ) regularly or in which each protuberance (8) extends continuously at least between a point A and a point D, and wherein each protuberance (8) comprises at least one cutout (11) positioned between the point A and the point D , the at least one cutout (11) being formed transversely to the protuberance (8) at a zone where the extension stress of the material of said protrusion (8) is maximum under load conditions and nominal pressure.
