The overlay ply includes cords oriented between −5° and +5° relative to the equatorial plane. | 04-24-2014 |
20140110034 | Pneumatic Tire and Method of Manufacturing Pneumatic Tire - A pneumatic tire includes: an annular structure that is cylindrical and metal where at least an outer side surface in the radial direction is a rough surface; a tread rubber layer that will become a tread portion provided along a circumferential direction of the annular structure on an outer side of the annular structure; and a carcass portion including fibers covered with rubber, provided on at least both sides in a direction parallel to a center axis of the cylindrical structure including the annular structure and the tread rubber layer. | 04-24-2014 |
20140216625 | PNEUMATIC TIRE CARCASS HAVING AIR BLOCKING STABILIZING FABRIC SYSTEM - A pneumatic tire carcass having a radial direction and a circumferential direction. The tire carcass comprises at least one ply of stabilizing fabric and an air-blocking layer attached to the stabilizing fabric. The stabilizing fabric contains a plurality of reinforcing yarns and is disposed within the carcass such that the reinforcing yarns are arranged in the radial direction of the carcass. The reinforcing yarns comprise monoaxially drawn tape elements having a rectangular cross-section, an upper surface, and a lower surface. The tape elements contain at least a first layer having a draw ratio of at least about 5, a modulus of at least about 2 GPa, and a density of at least 0.85 g/cm | 08-07-2014 |
20140216626 | PNEUMATIC TIRE CARCASS HAVING AIR BLOCKING STABILIZING FABRIC SYSTEM - A pneumatic tire carcass having a radial direction and a circumferential direction. The tire carcass comprises at least one ply of stabilizing fabric embedded into an air-blocking layer. The stabilizing fabric contains a plurality of reinforcing yarns and is disposed within the carcass such that the reinforcing yarns are arranged in the radial direction of the carcass. The air-blocking layer contains a polymer selected from the group consisting of polyolefin, ethyl vinyl acetate, polyisobutalyene or polyurethane, polyamide, polyester, co-polymers of PA and PES, dynamically vulcanized alloy resin, co-polymers, and mixtures thereof. | 08-07-2014 |
20150027612 | Vehicle Tire Comprising a Layer of Circumferential Reinforcing Elements - A tire with radial carcass reinforcement comprises a crown reinforcement including a layer of circumferential reinforcing elements distributed axially at a variable pitch. The layer of circumferential reinforcing elements is radially crowned by a tread strip, which is connected to two beads by two sidewalls. The layer of circumferential reinforcing elements comprises five parts, including a central part, two intermediate parts and two axially outer parts. The value of the pitch in the two intermediate parts is less than a value of the pitch in the two axially outer parts. Each axially outer part is axially separated from the central part by a corresponding intermediate part. The value of the pitch in each intermediate part is less than a value of the pitch in the central part, and the value of the pitch in each axially outer part is less than the value of the pitch in the central part. | 01-29-2015 |
20160059629 | METHOD OF MAKING A DUAL PLY TIRE AND TIRE CARCASS - A method of making a tire carcass is described. The method includes providing a first and second bead; aligning the first and second bead in parallel relationship to each other, and aligning the centers of each bead on a central axis; winding a strip of ply about the first and second bead so that the strip of ply extends between the beads in parallel relationship to the central axis forming a first stage tire carcass having two layers of ply. The method results in a tire having a carcass formed of a dual wrapped ply that is continuous in nature. | 03-03-2016 |
