Abstract
The tire comprises a tread, a crown reinforcement and at least one crown layer. The crown layer has an axial width (L2) that is at least two-thirds of a maximum axial width (L1) of the tire and has a concave portion with axial limits (M2, M′2) on either side of an equatorial plane (XZ). The tire further includes a carcass reinforcement which has at least one carcass layer with a concave portion that has axial limits (M3, M′3) on either side of the equatorial plane (XZ). The radial distance (d) between the respective concave portions is at a maximum in the equatorial plane (XZ) and decreases continuously from the equatorial plane (XZ) as far as the axial limits (M2, M′2) of the said concave portions axially closest to the equatorial plane (XZ), where it reaches a minimum value (dM).
