Embodiment Construction

[0038] Figure 1 shows a tire 1 according to the invention mounted, inflated on a rim 2, for mounting on a passenger vehicle. When viewed in a meridian section, the tire comprises a crown 9 connected to the bead 3 and 3' of said tire 1 by two sidewalls 4 and 4', of which the first sidewall 4 is called the outer sidewall, And the second side wall 4' is called the inner side wall. The beads 3 and 3' of the tire 1 comprise, radially on the inside, an angled section open axially and radially outwards, these inclined sections are designed to come into contact with the seat 21, 21' of the rim 2, which is also inclined An angle γ, which is the same in both cases, which opens axially and radially outwardly, when the tire is mounted on its service rim, principally because of said tire pressurization, between the rim seat and the tire A mechanical compression effect is obtained between the bead. Additionally, as is known, the rim seat includes flanges 22, 22' for limiting axial movemen...

Abstract

A tire comprising two beads, a crown and sidewalls that connect the crown to said beads, the tire being reinforced by a carcass reinforcement anchored in each bead to at least one annular anchoring element, each sidewall comprising an additional, inextensible sidewall ring located axially inside the axially outermost carcass ply and a coupling section located radially between the annular anchoring element in the bead and said sidewall ring and positioned axially inside the axially outermost carcass ply. The tire is characterized in that the line segments passing through the centers of gravity of the sections of the annular anchoring rings in the beads and through the center of gravity of the sidewall rings on the same respective side, make angles respectively of beta1 and beta2 relative to the rotation axis, these angles being different.

Description

technical field [0001] The present invention relates to tires with a radial or radial carcass, particularly (but not exclusively) for mounting on vehicles traveling at high speeds. Background technique [0002] When a vehicle equipped with a tire with a radial or radial carcass is driven in a circle on a curve, the driving conditions change, especially the footprint (that is, the distance between the tread of each tire and the road the vehicle is driving on). The contour shape of the contact surface and its area change greatly. Given the contact forces between the tires and the road, this leads to driving situations that can produce borderline phenomena, which are difficult for the driver to control (especially at high speeds). [0003] In the structure adopted, when turning in a circle (turning) on ​​a curve, the tires of the vehicle on the outside of the curve are subjected to lateral forces of greater or lesser intensity, which originate from the contact between the grou...
