Abstract:
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.
Abstract:
The invention relates to a tire having a lug and groove configured rubber tread having an outer rubber cap layer with a running surface and an underlying specialized transition rubber layer. The transition rubber layer is specialized in a sense of containing at least one of partially depolymerized rubber, particulate pre-cured rubber and coal dust. The outer tread cap layer is comprised of ground-contacting tread lugs with the tread running surface and associated tread grooves positioned between said tread lugs. The tread grooves may extend radially inward through the outer tread cap layer and, optionally, into the transition tread layer. The rubber tread configuration may also optionally also include a tread base rubber layer underlying the transition rubber layer.
Abstract:
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.

Abstract:
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.
Abstract:
A tire carcass is disclosed herein which includes a first radial ply, first and second sidewalls, a carcass crown portion, the carcass crown portion having a first edge and a second edge, and a non-continuous second radial ply, the second radial ply having a right side extending from approximately the first edge of the carcass crown portion, and extending approximately to at least the first bead core and a left side extending from approximately the second edge of the carcass crown portion, and extending approximately to at least the second bead core, wherein at least one of the sidewalls and the carcass crown portion are made of dissimilar material.
Abstract:
The invention relates to a tire with a tread which is quantitatively reinforced with silica where the tread is composed of three basic elastomers, namely, emulsion polymerization prepared styrene/butadiene rubber, cis 1,4-polybutadiene rubber and high vinyl polybutadiene rubber. Optionally, the basic elastomer composition can also contain a minor amount of cis 1,4-polyisoprene natural rubber.
