Abstract:
1. A tire for a two-wheeled motorized vehicle comprising at least one carcass-type reinforcement structure, formed of reinforcement elements forming with the circumferential direction an angle of between 65° and 90°, anchored on either side of the tire to a bead whose base is intended to be fitted on a rim seat, each bead being extended radially towards the outside by a sidewall, the sidewalls meeting up, radially towards the outside, with a tread whose Ht/Wt ratio is greater than 0.15, said carcass reinforcement being radially surmounted at least in the zone of the tread by a crown reinforcement formed of at least one layer of circumferential reinforcement elements, wherein said circumferential reinforcement elements are distributed in the transverse direction with a variable pitch, wherein said pitch is smaller at the centre (crown) of the tread than at the edges of said layer and wherein the value of the pitch in the transverse direction follows an increasing mathematical progression over at least part of the axial width of said layer.
