Abstract: Tire (1) for a vehicle, comprising a radially outermost working layer (41) which comprises at least one undulation (412) in line with a rib (26). The undulation (412) is such that it is radially on the outside of the points of the working layer (41) that are in line with the centre of the bottom face (243) of the circumferential groove (25) closest to the undulation (412) and that the minimum radial distance (do), between the radially outer surface of the radially outermost working layer (41) and the tread surface (21) is at least 1 mm less than the radial distance (dc) between the radially outer surface (ROS) of the radially outermost working layer (41) and the tread surface (21), which is the distance in line with the circumferential groove (25) closest to the undulation (412) concerned.

Abstract: Tire comprising major grooves with a depth at least equal to 4 mm and with a width at least equal to 1 mm. The radially outermost working layer (41) comprises at least one undulation (412). The undulation (412) is such that the undulation (412) portion of the working layer (41) represents at least 10% of the surface of the working layer (41), has an amplitude of at least 1 mm and is radially on the outside of the points of the working layer (41) that are in line with the bottom face (243) of the major groove (24) closest (412). All the layers of material (3, 6, 7) making up the radial stack of the crown structure (S) have mean surfaces parallel to that of the radially outermost working layer (41).

Abstract: Tire comprising at least one working layer (41). The radially outermost one thereof comprises at least one undulation (412) radially on the outside of the points of the working layer (41) that are in line with the centre of the bottom face (243) of the major groove (24) closest to undulation (412). The undulation (412) of the radially outermost working layer (41) is such that, over at least 10% of the radially outer surface (ROS) of the said working layer (41), the radial distance (do) between the radially outer surface (ROS) and the tread surface (21) is at least 1 mm less than the radial distance (dc) between the radially outer surface (ROS) and the tread surface (21), which is the distance in line with the centre of the bottom face (243) of the major groove (24) closest to the said undulation (412).
