| A tire for a vehicle wheel, capable of withstanding the load at low pressure or zero pressure, includes a carcass, a crown, two axially opposed sidewalls, two bead cores, two compression-resistant annular reinforcing elements, and, optionally, a belt structure. The annular reinforcing elements are made of material having high rigidity and very low elastic hysteresis. Each annular reinforcing element is in or adjacent to a zone joining the crown to a sidewall and in a first plane parallel to an equatorial plane of the tire. Each bead core is in a second plane parallel to the equatorial plane. The distance between the first planes is greater than or equal to the distance between the second planes. A camber of an arc between a bead core and an intersection of a carcass ply line with a cylindrical surface passing through the reinforcing elements does not exceed 15% of the arc length. | ||||||

| 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 &agr; 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. | ||||||

| 32 | Pneumatic safety tire | US839014 | 1977-10-03 | US4365659A | 1982-12-28 | Akira Yoshida; Masanori Kan |
| The present invention relates to a pneumatic safety tire, which is provided with a ring-shaped projection of high rigidity along its circumferential direction, outside of at least one bead of the pneumatic tire, wherein the projection has a smaller diameter than the diameter of the rim flange to which the tire is fitted. The ring-shaped projection is designed so that it projects to the outside along the rim flange, and moreover, the tire is adhered integrally by vulcanization together with two ring-shaped elastic reinforcements and halogenated butyl rubber-containing protective layer in the inside of the tire at each position corresponding to the portion from the sidewall to the adjacent shoulder. Thus, the purpose of the invention is to provide a pneumatic safety tire, which can be driven safely without there happening such an accident as separation of the bead of the tire from the rim during running, even when the tire is run flat and moreover, has a good stability and durability in running also in such a state. | ||||||
