Patent ID: 8770246

Claim:
A tire with a radial carcass reinforcement comprising a crown reinforcement formed of at least two working crown layers of inextensible reinforcing elements, crossed from one layer to the other making angles of between 10° and 45° with the circumferential direction, itself radially capped by a tread, the tread being connected to two beads via two sidewalls, the crown reinforcement comprising at least one layer of circumferential reinforcing elements distributed axially at a variable pitch, wherein the layer of circumferential reinforcing elements comprises five parts, these being a central part, two intermediate parts and two axially exterior parts, wherein the pitch in the central part is in the range between 1 and 1.5 times the pitch of the axially exterior parts and wherein the pitch in an intermediate part is in the range between 1.6 and 2 times the pitch of the axially exterior parts, wherein the axial width of the central part of the layer of circumferential reinforcing elements is in the range between 30 and 40% of the axial width of the layer of circumferential reinforcing elements.
