Abstract
A non-pneumatic wheel (1) comprises a crown reinforcing region (10) itself radially on the inside of a tread (7), the crown reinforcing region (10) comprising a plurality of reinforcing strips (12, 14) arranged in at least three layers of strips (12, 14) arranged in such a way that a virtual axis C-C substantially perpendicular to the strips intersects at least two strips in any axial position of the virtual axis in the crown reinforcing region.

A non-pneumatic wheel comprising an annular reinforcing structure produced from at least one elastomer compound, arranged radially on the inside of a tread, the annular reinforcing structure comprising a plurality of reinforcing strips arranged in layers, the reinforcing strips of each of the layers being arranged in an axial juxtaposition and being oriented in a substantially circumferential direction, the reinforcing strips being made of a thermoplastic film having a modulus higher than 0.9 GPa in the main direction and in the transverse direction, and the reinforcing strips being coated with an elastomer composition,
- wherein the annular reinforcing structure comprises N radially superposed layers of reinforcing strips, N being greater than or equal to three, and
- wherein a virtual axis C-C substantially perpendicular to the reinforcing strips intersects at least N−1 reinforcing strips in any axial position of the virtual axis in the annular reinforcing structure.
