摘要:
A tire and method of building a tire is described wherein the tire has a carcass having a pair of sidewall plies and a bridge ply, each ply being reinforced with cords, the sidewall plies each having a first end which is received between the bridge ply and a belt reinforcing structure; wherein each sidewall ply extends axially outward along the sidewall and extending radially inwardly to the bead core and folded from a position axially outside the bead core to a position axially inside and around the bead core to an axially inner turnup end; said bridge ply having ends which overlap with a respective inner turnup end of said sidewall ply.
摘要:
The tire includes a first and second axially-spaced bead core, a carcass having at least one belt extending under a tread, and a first ply layer having first and second ends, a first end is located axially outside and adjacent a first bead core, and a second end that is located axially outside and adjacent a second bead core. The carcass further comprises first and second shoulder ply layers each shoulder ply layer having first and second ends, a first end is located under the tread belt, the shoulder ply extending down the side wall region with the second end folding from a position axially outside a respective bead core to a position axially inside and around the bead core. The carcass further comprises an additional reinforcement layer which wraps around the bead and is preferably positioned between the shoulder ply and the first ply layer, although not required.

A tire carcass to be used with any type of tire is shown herein. A tire carcass includes a first ply portion, a second ply portion, each ply portion having an inner sidewall ply, an outer sidewall ply, a first end, a second end, and a bead core, a bridge portion, wherein the first ends of the ply portions are separated by the bridge portion, and at least two bridge plies, wherein the bridge plies span the bridge portion, wherein each of the bridge plies have a first end and a second end.

A carcass for a pneumatic tire includes a first annular bead, a second annular bead, a first continuous radial ply, a second continuous radial ply, and a third non-continuous radial ply. The first radial ply has two shoulder portions and two lateral edge portions. One lateral edge portion of the first ply extends from one shoulder portion of the first ply radially inward to a location proximal to the first annular bead. The other lateral edge portion of the first ply extends from the other shoulder portion of the first ply radially inward to a location proximal to the second annular bead. The second continuous radial ply has two shoulder portions and two lateral edge portions. One lateral edge portion of the second ply extends from one shoulder portion of the second ply radially inward to a location proximal to the first annular bead. The other lateral edge portion of the second ply extends from the other shoulder portion of the second ply radially inward to a location proximal to the second annular bead. The third non-continuous radial ply has a first portion and a second portion separate and distinct from the first portion. The first portion of the third ply extends from a location proximal to one shoulder portion of the second ply to a location proximal to the first annular bead. The second portion extends from the other shoulder portion of the second ply to a location proximal to the second annular bead.

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.

A pneumatic tire has a carcass structure extending through a pair of opposing bead portions and an inner liner located inward of the carcass structure, each bead portion comprising a bead core about which is wrapped the carcass structure and a toeguard. Each bead portion has a bead toe, a bead base, and a bead heel, the bead base extending between the bead toe and the bead heel. The bead heel has a profile corresponding to a sector of an ellipse or approximates a sector of an ellipse by having a dual radius structure. The bead base may have a dual taper configuration. The bead core may be substantially centered in the bead portion, as determined by the material thickness at three locations about the bead core.
