Patent ID: 6938657

Claim:
A tyre for a vehicle wheel, capable of withstanding a load applied on the wheel by the vehicle at low pressure or zero pressure, comprising: a carcass; a crown; two axially opposed sidewalls; two bead cores; two compression-resistant annular reinforcing elements; and optionally, a belt structure; wherein the crown comprises a tread band, wherein the crown is radially external to the carcass, wherein each bead core is near a respective radially inner end of the carcass, wherein the belt structure, if present, is between the carcass and the tread band, wherein the annular reinforcing elements are made of material having high rigidity and very low elastic hysteresis, wherein each annular reinforcing element is in or adjacent to a zone joining the crown to a respective sidewall, wherein a geometric center of each annular reinforcing element is in a respective first plane parallel to an equatorial plane of the tyre, wherein a geometric center of each bead core is in a respective second plane parallel to the equatorial plane of the tyre, wherein a first distance between the first planes is greater than or equal to a second distance between the second planes, wherein a camber of an arc along an inner surface of the carcass between an axially inner edge of a respective bead core and an intersection of the inner surface of the carcass with a cylindrical surface passing through the geometric center of the two reinforcing elements does not exceed 15% of a length of the arc, and wherein the tyre comprises an aspect ratio greater than or equal to 0.3 and less than or equal to 0.7.
