    Abstract: Provided are: a tire reinforcement member having an improved durability; and a tire whose weight is reduced and durability is improved by using the tire reinforcement member.The tire reinforcement member is a tire reinforcement member 1 formed by winding a rubber strip 2 at an inclination with respect to the longitudinal direction of the member without any gaps while folding at width direction ends of the member, the rubber strip 2 being obtained by rubber-coating one reinforcing cord or a plurality of paralleled reinforcing cords. The rubber strip 2 substantially forms two reinforcing layers having different inclination directions. At a folding part T closest to a winding finish end 2e of the rubber strip 2, the rubber strip 2 is passed under an already wound rubber strip 2A and then folded, the already wound rubber strip 2A has been wound previous to the rubber strip 2 in an inclination direction different from that of the rubber strip 2.

    Abstract: It is an object to provide a reinforcing member for a tire that can further improve tire durability by enhancing durability of members themselves used for a tire reinforcement use, and a tire in which durability is further improved by using this reinforcing member for a tire.The reinforcing member for a tire includes a network structure made of a plurality of reinforcing materials, in which the network structure is made of a knotted net or a knotless net. The tire is reinforced by this reinforcing member for a tire.

    Abstract: A pneumatic tire according to the present disclosure includes a pair of bead cores, a carcass ply including a main body positioned between the bead cores and a turn-up portion connected to the main body and formed by turning up around each bead core from inside to outside in a tire width direction, a cover rubber covering the main body of the carcass ply and an outer side of the turn-up portion in the tire width direction and configuring a tire outer surface, and a reinforcement layer located inward from the tire outer surface of the cover rubber and covering an outer side, in the tire width direction, of at least a portion of the turn-up portion of the carcass ply. The reinforcement layer is configured by a non-woven fabric including metal fibers or a rubber sheet material having metal fibers embedded therein.

    Abstract: A pneumatic tire according to the present disclosure includes a ply including a plurality of cords arranged in parallel to each other, a cover rubber covering the ply and configuring a tire outer surface, and a reinforcement layer that, at a position of a cut edge of the ply, covers the cut edge of the ply on one side or both sides in a ply thickness direction. The reinforcement layer is configured by a non-woven fabric comprising metal fibers or a rubber sheet material having metal fibers embedded therein.
