Abstract
A tire having a radial carcass reinforcement includes a crown reinforcement formed of at least two working crown layers of inextensible reinforcement elements, which are crossed from one ply to the other, forming with the circumferential direction angles of between 10° and 45°. The crown reinforcement is topped radially by a tread, which is joined to two beads by means of two sidewalls. The ratio of the thickness of the crown block at one shoulder end to the thickness of the crown block in the circumferential median plane is less than 1.20. The ratio of the axial width of the tread to the maximum axial width of the tire is strictly greater than or equal to 0.89.
