<p>A tire with radial carcass reinforcement comprises a crown reinforcement including a layer of circumferential reinforcing elements distributed axially at a variable pitch. The layer of circumferential reinforcing elements is radially crowned by a tread strip, which is connected to two beads by two sidewalls. The layer of circumferential reinforcing elements comprises five parts, including a central part, two intermediate parts and two axially outer parts. The value of the pitch in the two intermediate parts is less than a value of the pitch in the two axially outer parts. Each axially outer part is axially separated from the central part by a corresponding intermediate part. The value of the pitch in each intermediate part is less than a value of the pitch in the central part, and the value of the pitch in each axially outer part is less than the value of the pitch in the central part.</p> |
