  • Patent number: 10343459
    Abstract: [Object] A pneumatic tire that allows reduction of the occurrence of a TGC and, at the same time, allows reduction of rolling resistance, is provided. [Solution] The tire 12 includes a band 26 disposed radially inward of a tread 14, and a belt 24 disposed radially inward of the band 26. The band 26 includes a cord that is helically wound and extends substantially in a circumferential direction. The belt 24 includes an inner layer 24a, and an outer layer 24b that is layered over the inner layer 24a and disposed radially outward of the inner layer 24a. The inner layer 24a and the outer layer 24b each include multiple cords aligned with each other. The cords in the inner layer 24a and the cords in the outer layer 24b are inclined relative to an equator plane. A direction in which the cords in the inner layer 24a are inclined relative to the equator plane is opposite to a direction in which the cords in the outer layer 24b are inclined relative to the equator plane.

  • Publication number: 20190135051
    Abstract: A pneumatic tire includes a carcass includes at least one carcass ply of cords extending between bead cores of bead portions through a tread portion and sidewall portions, wherein both ends of the carcass ply are turned up around the respective bead cores, and a pair of bead apex rubbers each extending radially outwardly to a radially outer end from a radially inner surface that is connected to the respective bead cores. In a tire meridian cross-section under a standard inflated state, in each of the bead portions, an angle of a bead reference line that passes an axially center point of the inner surface of the bead apex rubber and the radially outer end of the bead apex rubber is in a range of from 28 to 35 degrees with respect to a tire radial line.

  • Patent number: 10195900
    Abstract: A pneumatic tire includes a carcass extending between bead cores of bead portions through a tread portion. A tire section width Wt (unit: mm) in relation to a bead diameter Db (unit: inch) satisfies the following equations, Wt??0.7257×(Db)2+42.763×Db?339.67, and Wt??0.7257×(Db)2+48.568×Db?552.33. In a tread thickness distribution curve f(y) represented by equation f(y)=1?t(y)/t(0), when y=0.4, the value of f(y) is of from 0.03 to 0.06, and a rate of change of the value of f(y) increases to y=0.4 and decreases thereafter, where t(y) denotes a tread thickness at each tire axial position Py, and y represents a ratio of an axial distance from the tire equatorial plane, to the maximum-width L of the carcass.

  • Patent number: 10155417
    Abstract: A pneumatic tire excellent in resistance to uneven wear, and crack resistance of a groove is provided. A position, on an equator plane, of a tread surface 20 of a tire 2 is represented as a point Pc. A position, at a maximum width, of an axially outer side surface 6a of a sidewall 6 is represented as a point Pe. A position that is a mid-point, in the radial direction, between the point Pc and the point Pe, and that is on the axially outer side surface 6a, is represented as a point Pd. When an internal pressure is enhanced from an internal pressure that is 0.05 times a normal internal pressure P to the normal internal pressure P, a value Fs of difference in amount of protrusion between an amount of protrusion Dd (mm) at the point Pd and an amount of protrusion De (mm) at the point Pe is calculated according to mathematical expression (1) in which a nominal width is represented as W (mm). The value Fs of difference in amount of protrusion is greater than ?0.4 and less than 0.5.

  • Patent number: 10071597
    Abstract: [Object] A pneumatic tire 2 that allows achievement of reduction of rolling resistance without taking influence on a mass into consideration, is provided. [Solution] A profile OL of the tire 2 includes a ground-contact surface 46 and a pair of side surfaces 48. In the profile OL, a zone from a point PB to a point PW is formed by three arcs. The arcs are a first arc, a second arc that extends almost outward from the first arc in the radial direction, and a third arc that extends almost outward from the second arc further in the radial direction. A ratio of a radius R2 of curvature of the second arc to a radius R1of curvature of the first arc is greater than or equal to 1.45 and not greater than 3.26. A ratio of a radius R3 of curvature of the third arc to the radius R1 of curvature of the first arc is greater than or equal to 0.45 and not greater than 0.56. Each sidewall 8 of the tire 2 has a first recess 50a and a second recess 50b that are recessed inward from the side surface 48.
