Provided is a tire in which low rolling resistance is improved by using reinforcing cords containing polyamide multifilaments as reinforcing cords of a reinforcing member of the tire. In a tire (10) that includes at least one belt reinforcing layer (3) covering the full width of a belt (2), the belt reinforcing layer (3) includes, as a constituent, a rubber-cord composite that is formed of a rubber and reinforcing cords containing multifilaments of a semi-aromatic polyamide composed of a polycondensate of an aromatic dicarboxylic acid-containing dicarboxylic acid and a non-aromatic diamine, or a polycondensate of a non-aromatic dicarboxylic acid and an aromatic diamine-containing diamine acid; and, when the width of a maximum-width belt layer constituting the belt (2) is defined as W, a region of at least more than 0.35 W from a tire equatorial plane is a sparse region in terms of the end count of the reinforcing cords in the belt reinforcing layer (3), while regions on the tire width-direction outer side of the sparse region are dense regions.

A plurality of CNTs are drawn out of VACNTs so as to be continuous in lines and are bundled into a thread shape, and a temporary thread bundled into a thread shape is temporarily wound on the first winder. The first winder is then rotated about an axis along a feeding direction of the temporary thread to twist the temporary thread while the temporary thread is fed from the first winder.

A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and embedded in the belt body. The belt tension T.sub.0.2 per 1 mm belt width at 0.2% of a belt extension rate is 70 N/mm or more. The belt tension T.sub.0.5 per 1 mm belt width at 0.5% of the belt extension rate is 220 N/mm or more. The ratio of the belt tension T.sub.0.2 to the belt tension T.sub.0.5 is 0.33 or more.

A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and provided to be embedded in the belt body and to form a helical pattern having a pitch in the belt width direction. When the cord is viewed from a side orthogonal to its length direction, an angle 0 of an outermost filament in the filament bundle of the carbon fibers forming the cord with respect to the length direction of the cord is 8° or more to 20° or less.
