Abstract

A tire (1) for a vehicle has a tread surface having a transverse radius RT and comprises a crown layer (3) that comprises at least one undulation (312) in line with a rib (26). The undulation (312) is such that it is radially on the outside of the points of the undulated layer in line with the center of the bottom face of the circumferential furrow (25) closest to the undulation (312) and has an amplitude at least equal to 1 mm. The radial distance (da) between at least one contact edge corner of a rib (26) in line with which an undulation is located and the transverse radius RT of the rib is at least equal to 0.2 mm and at most equal to 2 mm.
