Abstract: A method forms a butt joint between ends of first and second plies and splices the first and second plies together. The method includes the steps of: positioning a first splice edge of a first ply at a first location; positioning a second splice edge of a second ply at a second location, the second splice edge being left bare; wrapping a gum strip around the first splice edge such that the first gum strip forms a U-shaped structure in section that allows the first gum strip to extend from a first planar side of the first ply over the first splice edge to a second opposite planar side of the first ply; not wrapping a gum strip around the second splice edge; placing the first splice edge in abutting relationship to the second splice edge; and stitching the first splice edge to the second splice edge such that stitches each extend from the first planar side of the first ply, through the gum strip, to the first planar side of the second ply.

Abstract: A carcass for a pneumatic tire may include a continuous ply and a non-continuous ply having first and second portions. The first and second portions may be positioned in the bead areas of the tire. Each end of the continuous ply may be positioned between the respective first and second portions of the non-continuous ply.

Abstract: A two-piece tire assembly with a removable tread belt for installing about the circumference of a tire carcass is provided. The inner surface of the tread belt follows a non-linear, preferably arcuate profile with a radius of curvature R across the tread belt wherein the distance DL as measured from the axis of rotation to the inner surface of the tread belt extends a distance DO at the equatorial plane and curves radially inwardly to a distance DE at each belt edge such that DE?0.9*DO.

Abstract: A tire carcass to be used with any type of tire is shown herein.

Abstract: 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.

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: The invention relates to a tire having a rubber tread configuration comprised of a circumferential non-cellular outer rubber cap rubber layer which contains a tread running surface, a circumferential internal, intermediate closed cellular rubber transition rubber layer positioned between said outer tread cap non-cellular rubber layer and a circumferential tread base non-cellular rubber layer. Said internal cellular rubber layer is thereby exclusive of said tread running surface and thereby abridges and joins said outer non-cellular rubber cap layer and said non-cellular base rubber layer of said tread configuration.
