Provided is a heavy duty tire 2 that can suppress a decrease in durability due to the provision of a band and can achieve improvement of uneven wear resistance. The tire 2 includes a reinforcing layer 20 and a tread 4. The tread 4 has shoulder circumferential grooves 34. The reinforcing layer 20 includes a belt 52 and a band 54. The belt 52 includes an inner belt ply 74 and an outer belt ply 76. The band 54 includes a full band 66. The full band 66 is located between the inner belt ply 74 and the outer belt ply 76. A distance UFc between the full band 66 and the inner belt ply 74 is longer than a distance SFc between the full band 66 and the outer belt ply 76 at an equator plane of the tire 2.

A tire comprises, in the central part of its crown, at least one undulation (51) of the radially outermost crown layer, having a radial amplitude A at least equal to 1 mm. At least one bead comprises, aside from the radial carcass layer and the bead wire, a radial reinforcing element that is such that the axial distance between the radial reinforcing element and the axially innermost carcass layer is at least equal to 1 mm and at most equal to 12 mm at the point of the radial reinforcing element that is situated 30 mm from the radially innermost point of the bead wire, for a better trade-off between the stiffness of the undulating crown and of the bead.
