  • Publication number: 20220016933
    Abstract: A tire comprises a tread portion provided with a band composed of at least one band cord wound spirally and circumferentially of the tire and embedded in the tread portion. When a band cord piece is taken out from the above-said at least one band cord embedded in the tread portion and measured for the length, a length Lb is equal to or smaller than a length La at least in a part of the tread portion, where the length Lb is measured at a first point of time after the band cord piece has been taken out, and the length La is measured at a second point of time after the first point of time.

  • Publication number: 20180312007
    Abstract: A tire 2 includes: a tread 4 forming a tread surface 20; a band 14 disposed inward of the tread 4 in a radial direction; and a belt 12 disposed between the tread 4 and the band 14 in the radial direction. The tread 4 includes a center region 22 disposed at a center in an axial direction, and a shoulder region 24 disposed on an outer side in the axial direction. The band 14 includes a band cord. The band cord is helically wound and extends in a circumferential direction. The belt 12 includes a belt cord. The belt cord extends so as to be tilted relative to an equator plane. An absolute value of an angle of the belt cord relative to the equator plane is not less than 70° and not greater than 90°.

  • Patent number: 9162531
    Abstract: A motorcycle tire comprises a tread portion provided with a plurality of inner inclined grooves and inclined narrow grooves in both sides of a tire equator, wherein each inner inclined groove extends from an axially inner end to the outer end with an angle of 0-20 degrees with respect to a tire circumferential direction, the inner end of the inner inclined groove is located in a developed length within 5% of a tread half developed-width from the tire equator, each inner inclined groove has a circumferential length of 70-85% of a first pitch, each inclined narrow groove with a groove width of 0.5-2.0 mm is provided between circumferentially adjacent inner inclined grooves and has an angle with respect to a circumferential direction of the tire larger than that of the inner inclined groove.

  • Publication number: 20080017290
    Abstract: A tire (22) according to the present invention includes a pair of beads (28), a carcass (30) and a belt (32). An absolute value of an angle formed by a carcass cord of the carcass (30) with respect to a circumferential direction is equal to or greater than 60 degrees and is equal to or smaller than 90 degrees. A belt ply (50) of the belt (32) is constituted by a center portion (52) and a pair of side portions (54) positioned on an outside in an axial direction of the center portion (52). A ratio of a perimeter of the center portion (52) to that of the side portion (54) is equal to or higher than 10% and is equal to or lower than 50%. The center portion (52) includes a center cord which is spirally wound in a substantially circumferential direction and is formed of steel. The side portion (54) includes a side cord which is spirally wound in the substantially circumferential direction and is formed by an aramid fiber.
