摘要:
A pneumatic tire has a puncture sealing layer radially inward of the tire carcass layer. The puncture sealing layer is formed by co-extruding a sealant material and an skin compound.

A tire 10 has a composite ply 40. The composite ply 40 has a primary ply 40A reinforced with parallel inextensible cords 41 and a pair of ply extensions 40B having synthetic cords. The method of manufacturing the tire 10 is described. The tire 10 can be made as a runflat type tire.
摘要:
A pneumatic radial ply tire (50) having a tread (52), a carcass (60) with two sidewalls (77, 78), one or more radial plies (70, 72), two annular beads (36a′, 36b′), a belt structure (56) located radially between the tread and the radial ply structure (58), a fabric underlay (54), deployed radially inward of the belt structure, and a tread insert (66) deployed between the belt structure and the fabric underlay. Said underlay (66) contains circumferentially aligned high-modulus fibers or cords (88) which, in combination with metal belt structure (56) and the tread insert (66), contribute to circumferential tread rigidity. Insert (66), in conjunction with the belt structure (56) and the radial ply structure (58), contributes to lateral tread rigidity. The circumferential and lateral stiffening of the tread (52) enhances high-speed runflat handling and contributes to improved runflat operational life.

摘要:
A pneumatic tire comprising a belt structure and a torus shaped carcass having a first inner radius and an outer radius, wherein the carcass is comprised of three or more layers of ply, wherein each layer of ply is formed from a rubberized strip of one or more cords, the strips being wound in an geodesic pattern having the cord extend across the carcass from a first shoulder to a second shoulder in a path that has at least one point tangent to the first inner radius located in the bead area of the tire.

A medallion assembly for a pneumatic tire, in accordance with the present invention, includes a protruding portion, a fastener, and a medallion. The protruding portion is integrally formed with a sidewall of the tire and extends away from the sidewall of the tire. The protruding portion has an annular tapered outer surface. The fastener has an annular tapered inner surface and an annular outer surface. The annular tapered inner surface engages the annular tapered outer surface of the protruding portion. The medallion has an annular inner surface for engaging the annular outer surface of the fastener such that the medallion is secured to the fastener and both the medallion and the fastener are secured to the protruding portion of the sidewall of the tire.
摘要:
The invention relates to a tire having a rubber tread comprised of cap/base construction where the tread cap layer provides the running surface of the tread and the tread base layer underlies the tread cap layer and thereby provides a transition between the tread cap layer and the tire carcass. For this invention, the tread cap layer is comprised of a plurality of individual circumferential load-bearing zones of rubber compositions, which exhibit graduated physical properties, and which extend from the outer running surface of the tread cap layer radially inward to said tread base layer. In one aspect, the zoned rubber tread cap layer and rubber tread base layer are co-extruded together to form a unit as an integral tread rubber composite.
