A pneumatic tire includes a strip member which extends in a tire circumferential direction, with both ends thereof reaching each bead portion, and a belt layer disposed in a tread portion on an outer side in the tire radial direction of the strip members. The strip members are divided in the tire width direction, with each of the divided strip members having joints that join in the tire circumferential direction. The relative positions of the joints are disposed at less than 20 in the tire circumferential direction within the region of the maximum width TW in the tire width direction of the belt layer.

A tire including: a circular tire frame containing a resin material; and a metal-resin complex wound around an outer circumferential portion of the tire frame, which includes a metal member, an adhesive layer and a resin layer in this order, and in which a tensile elastic modulus of the adhesive layer is less than a tensile elastic modulus of the resin layer.

The device for producing a tire component by winding, comprises: a helicoidal external wall, and means for adjusting a diameter of the wall.

Provided are: a rubber-reinforcing fiber, in which adhesion between a rubber and a fiber is enhanced and which is thereby capable of further improving the durability than before when used as a reinforcing material; a rubber-fiber composite; and a pneumatic tire using the same. The rubber-reinforcing fiber includes a core-sheath type composite fiber whose core portion is composed of a high-melting-point resin (A) having a melting point of 150 C. or higher and sheath portion is composed of a resin material (B) having a melting point lower than that of the high-melting point resin (A). The resin material (B) contains an olefin-based polymer (X) and a vulcanization accelerator (F).

A tire comprises: a tire frame member made of resin and including a bead portion and a side portion positioned on a tire radial direction outer side of the bead portion; and a reinforcing layer including an organic fiber and a resin material with which the organic fiber is coated, wherein the organic fiber comprises: a cord member including at least one of an aramid fiber material or a polyester fiber material; an undercoat layer provided on the cord member and formed from a first composition including at least one of an epoxy compound or an isocyanate compound; and an adhesive layer provided on the undercoat layer and formed from a second composition including a resorcinol-formaldehyde resin.

A tire includes: a ring shaped tire frame member that is made of a resin with plural tire pieces joined along a tire circumferential direction; a joint portion reinforcing belt that is adhered to the tire frame member, that extends around the tire circumferential direction, and that covers a joint portion of the plural tire pieces; and a tread layer that is provided further to the tire radial direction outside than the tire frame member and the joint portion reinforcing belt.

A method of making a tire comprising the steps of providing a core; forming a first layer of ply by winding a strip of one or more rubber coated cords onto the core in a geodesic pattern extending from a first shoulder to a second shoulder opposite said first shoulder and being tangent to the bead at a location between said first shoulder and said second shoulder.

The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.

The provide is an tire and an tire production method for the tire, wherein the carcass ply is comprised of tape-like members arranged in the tire circumferential direction, in which a plurality of carcass cords arranged parallel to each other are coated with rubber; the tape-like member has a tape width of 1 to 10 mm; on the tire equatorial plane, two of the tape-like members adjacent to each other in the tire circumferential direction are butted against each other at tire circumferential ends thereof; and at the end portions of the carcass ply, two of the tape-like members adjacent to each other in the tire circumferential direction overlap each other only at rubber portions thereof.

In a pneumatic tire that includes strip members which extends in a tire circumferential direction, both ends thereof reaching each bead portion, a belt layer is disposed in a tread portion on an outer side in a tire radial direction of the strip members. The strip members are divided in the tire width direction, and the divided strip members have joints that join together in the tire circumferential direction. Relative positions of the joints are disposed deviated by not less than 20 in the tire circumferential direction within a region between an edge of a maximum width in the tire width direction of the belt layer and a maximum tire width position.
