摘要： In a tread-forming surface of a mold, a contour of a land surface-forming portion located between two projections among at least three land surface-forming portions can be represented by a single circular arc that is convex outward. In a case where, of the two projections, one projection is a wide projection and the other projection is a narrow projection, when a surface that has a contour represented by at least one circular arc and that is tangent to the at least three land surface-forming portions is defined as a reference surface of the tread-forming surface, a drop distance from the reference surface to an end on the wide projection side of the land surface-forming portion can be longer than a drop distance from the reference surface to an end on the narrow projection side of the land surface-forming portion.

摘要： In a tire, a shape index of a reference ground contact surface is not less than 1.20 and not greater than 1.50. In the tire, a tread includes a cap layer, an intermediate layer formed such that a loss tangent of the intermediate layer at 30° C. is less than a loss tangent of the cap layer at 30° C. and a base layer formed such that a loss tangent of the base layer at 30° C. is less than the loss tangent of the intermediate layer at 30° C. In the radial direction, the intermediate layer is disposed outwardly of the base layer and the cap layer is disposed outwardly of the intermediate layer. In a shoulder land portion of the tread, a thickness of the cap layer at a center of an axial width is less than a thickness of the cap layer on the shoulder circumferential groove side.

摘要： A pneumatic tire includes a tread portion including an inboard shoulder land portion defined between an inboard tread edge and an inboard shoulder main groove. The inboard shoulder land portion is provided with inboard semi-open shoulder lateral grooves and inboard shoulder sipes extending axially inwardly from the inboard tread edge and terminate within the inboard shoulder land portion.

摘要： In a tire, a tread includes a cap layer, an intermediate layer formed such that a loss tangent of the intermediate layer at 30° C. is less than a loss tangent of the cap layer at 30° C., and a base layer formed such that a loss tangent of the base layer at 30° C. is less than the loss tangent of the intermediate layer at 30° C. The intermediate layer is disposed outwardly of the base layer and the cap layer is disposed outwardly of the intermediate layer, in the radial direction. An outer end of the intermediate layer is disposed outwardly of an outer end of the base layer and an outer end of the cap layer is disposed inwardly of the outer end of the intermediate layer, in the axial direction. A difference between an axial width of the cap layer and an axial width of the base layer is not less than −10 mm and not greater than 10 mm.

摘要： In a tire 22, a length from a center PM in an axial direction of a boundary 60 between a core 48 and an apex 50 to an outer edge PA of the apex 50 is not less than 10 mm and not greater than 15 mm. In a state where the tire 22 is mounted on a normal rim and an internal pressure of the tire 22 is adjusted to 10% of a normal internal pressure, a main body portion 54 of a carcass ply 52 extending along an inner surface 62 of the apex 50 is tilted relative to the axial direction, and an angle of the main body portion 54 relative to the axial direction is not less than 40° and not greater than 60°.

摘要： A tire 2 includes a tread 4, a pair of sidewalls 6, a pair of beads 10, a carcass 12, a belt 14, an inner liner 20, and a pair of insertion layers 22 disposed between the carcass 12 and the inner liner 20. Each insertion layer 22 is disposed between an end of the belt 14 and an end PB of the bead 10. Each insertion layer 22 has a volume resistivity of less than 108 Ω·cm. A complex elastic modulus of the insertion layer 22 is equivalent to or higher than a complex elastic modulus of the inner liner 20. A thickness of each sidewall 6 at a maximum width position PW is not greater than 5.0 mm.
