Title:
三角形クラウン補強体を備えたタイヤ
Document Type and Number:
Japanese Patent JP4383662
Kind Code:
B2
Abstract:
A tire with a form ratio H/S between 0.3 and 0.8 has a carcass reinforcement (1) which is covered radially by a quasi-cylindrical crown reinforcement (3) and which is tangential at T to a holding circle C. The common tangent at T to the circle C and to the meridian profile of the carcass (1) makes an angle alpha of between +20° and -80° with respect to a line parallel to the rotation axis and passing through the tangency point T. In its portion located between the tangency point T and the point E of greatest axial width, the carcass reinforcement (1) is provided with a reinforcement armature (6) of circumferentially non-extensible elements. Viewed in meridian cross-section and when the tire is fitted and inflated to the recommended pressure, the carcass (1) has a meridian profile consisting of four circular arcs configured to improve the endurance of the tire while improving its rolling resistance.
