Claim Text:
1. A tire configured for at least one of a truck and a bus having an aspect ratio H/S strictly greater than 0.55 and less than 0.75, said tire having a radial carcass reinforcement comprising a crown reinforcement formed of at least two working crown layers of inextensible reinforcement elements, crossed from one ply to another forming angles of between 10 and 45 with a circumferential direction, said crown reinforcement being topped radially by a tread, said tread being joined to two beads by means of two sidewalls, the crown reinforcement comprising at least one layer of circumferential reinforcement elements, wherein the ratio of a thickness of a crown block at one shoulder end to a thickness of the crown block in a circumferential median plane is less than 1.20 and greater than 1; wherein the thickness of a crown block at one shoulder end is defined by a length of an orthogonal projection of the shoulder end on a radially innermost layer of rubber mix of the tire from the shoulder end on the outer surface of the tire to the radially innermost layer of rubber mix; and wherein the shoulder end is defined, in a zone of the shoulder of the tire, by the orthogonal projection orthogonal to an outer surface of the tire of an intersection of tangents to surfaces of an axially outer end of the tread and of a radially outer end of a sidewall, wherein the ratio of the axial width of the at least one layer of circumferential reinforcement elements to the axial width of the tread is greater than 0.65, wherein a ratio of the axial width of the tread to a maximum axial width of the tire is greater than or equal to 0.80.
