    Abstract: A tire comprising a carcass reinforcement (2) surmounted radially on the outside by a crown reinforcement (3), itself radially on the inside of a tread (4) having two axially outermost ends. The crown reinforcement (3) has a layer of reinforcing elements. The tread is connected to two beads (5) by two sidewalls (6), each bead (5) comprising at least one circumferential reinforcing element. Sidewalls (6) comprise, on their exterior surface, a series of protuberances (8) alternating with voids (9). The tread (4) comprises, at least at one axially outermost end (4a), a circumferential groove (10), wherein each protuberance (8) is positioned at the surface of a sidewall, the different protuberances being arranged regularly or irregularly and continuously between a point A and a point E, and wherein at least one protuberance (8) partially or completely interrupts or does not interrupt the circumferential groove (10).

    Abstract: The invention relates to a tire having at least one carcass reinforcement (2) comprising reinforcers, surmounted radially on the outside by a crown reinforcement (3) comprising two axial ends S, itself radially on the inside of a tread (4), said crown reinforcement (3) being made up of at least one layer of reinforcement elements, said tread (4) being connected to two beads (5) by way of two sidewalls (6), said beads (5) being intended to come into contact with a rim flange having a rim flange top C, each bead having at least one circumferential reinforcement element (7) known as a bead wire, said carcass reinforcement (2) comprising an end (8) at each bead (5), the end (8) of the carcass reinforcement (2) being turned up once in an outward radial direction of the tire and about said bead wire, so as to form a turnup, then being folded in the radially outward direction so as to form a fold of the carcass ply (2), said fold forming a radially external end (12a) and three adjacent parts along an axial axis made up of a central part (10), of an axially internal lateral part (11), and of an axially external lateral part (0), the fold being executed in an outward axial direction with respect to the center of the tire, characterized in that a decoupling elastomer composition (14) having a secant modulus at 10% extension of greater than or equal to 10 MPa and preferably greater than or equal to 30 MPa and less than or equal to 60 MPa is present between the axially internal lateral part and the central part of said turnup, and at the radially external end (12a) of said turnup (12), said elastomer composition being present along a radial length comprised between the radially external end of the turnup and a radially internal point F with respect to the end of said turnup, said point being situated on the sidewall and at a distance from said radially external end by a length greater than 10 mm, and in that the radially external end (12a) of the turnup (12) is disposed between the rim flange top C and a point D, said points C and D being situated at the surface of the sidewall (6) and disposed on either side of a point E situated on the sidewall corresponding to the nominal section width, said point D being disposed at a maximum radial length equal to 85% of the length present between the axial end S of the crown reinforcement (3) and the rim flange top C.
