  • Publication number: 20240227450
    Abstract: A tire includes a tread portion; a pair of bead portions; a pair of sidewall portions, each of which extend between the tread portion and a respective bead portion; a carcass that extends from one bead portion to the other, through the sidewall portions and tread portion; and an inner surface that defines a tire cavity; wherein the tread portion comprises a belt disposed outside of the carcass in a radial direction of the tire, the belt comprising one or more belt plies that extend in an axial direction of the tire; wherein each sidewall portion comprises an intermediate layer arranged inward in the tire radial direction from the carcass, wherein each intermediate layer comprises an outer edge that overlaps the belt and an inner edge arranged in the sidewall portion or bead portion; wherein the tire further comprises an inner layer arranged inward in the tire radial direction from the tread portion, the inner layer having a thickness in the radial direction defined by the carcass and inner surface; and wherei

  • Publication number: 20240227446
    Abstract: A pneumatic tire comprises: a tread portion having a ground contacting surface; a sidewall portions having an outer surface; a bead portions; a carcass extending between the bead portions; and an inner rubber extending between bead portions. The inner rubber comprises a first portion extending through the tread portion with a first thickness t1, and a second portion extending through the sidewall portion with a second thickness t2. The first thickness t1 is more than the second thickness t2. In a meridian cross section of the tire under its normal state, when a first reference point (Pb1), a second reference point (Pb2), a shoulder reference point (Ps), a reference line segment (Lb), and a shoulder line segment (Ls) are defined, then a length (L1) of the shoulder line segment (Ls) is 85.9% to 89.3% of a length (L2) of the reference line segment (Lb).

  • Publication number: 20240227445
    Abstract: A pneumatic tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, a carcass extending between the pair of bead portions, and an inner rubber extending between the pair of bead portions on an inner side of the carcass. The inner rubber includes a first portion extending in the tread portion with a first thickness and a second portion extending in each of or one of the pair of sidewall portions with a second thickness. The first thickness is greater than the second thickness. In a tire meridian cross-section, a cross-sectional area of the inner rubber is in a range from 1.5% to 10% of an inner-cavity cross-sectional area of the pneumatic tire.

  • Patent number: 11618283
    Abstract: In a tire 2, a length from a center in an axial direction of a boundary between a core 30 and an apex 32 of each bead 10 to an outer end PA of the apex 32 is not less than 10 mm and not greater than 15 mm. In a state where the tire 2 is mounted on a normal rim and an internal pressure of the tire 2 is adjusted to a normal internal pressure, a shape of a main body portion 36, of a carcass ply 34, which is located in a zone from a boundary portion between a tread 4 and each sidewall 6 to the outer end PA of each apex 32 is represented by a single circular arc, and a diameter of the circular arc is not less than 75% and not greater than 90% of a cross-sectional height of a carcass 14.

  • Patent number: 9744810
    Abstract: A pneumatic tire includes a tread having a center main groove and a pair of shoulder main grooves. A pair of middle land sections in the tread is positioned between the shoulder and center grooves. Each of the shoulder and center grooves has a groove width set in range of 7 to 9% of width of the tread footprint. An outer middle land portion is divided into first and second middle land portions by a middle narrow groove. The first land portion forms rib. The second land portion has outer middle lateral grooves connected to the center groove and the narrow groove. Each lateral groove includes first portion, second portion having the opposite inclination to the first portion and connection portion between the first and second portions. The connection portion is positioned on the center groove side from the center of the outer land portion in the axial direction.
