摘要： A pneumatic tire having sufficiently improved wet performance is provided. A pneumatic tire comprises a tread rubber that includes: a tread surface rubber layer located at an outermost surface of a tread; and a tread inside rubber layer located on a tire radial inner side of the tread surface rubber layer. A 100% modulus of the tread surface rubber layer is higher than a 100% modulus of the tread inside rubber layer, and the tread surface rubber layer is made of a rubber composition including: a rubber component (A) containing 50 mass% or more of diene-based rubber; and, with respect to 100 parts by mass of the rubber component (A), 5 to 50 parts by mass of at least one additive component (B) selected from: thermoplastic resin; oil; and an aromatic vinyl compound-conjugated diene compound copolymer whose polystyrene-equivalent weight-average molecular weight measured by gel permeation chromatography is 5,000 to 200,000.

摘要： By forming a ground contact edge side of lug grooves (16) such that the groove depth becomes shallower in groove depth from the tire equatorial plane side toward the ground contact edge, and by setting an average angle of inclination (¸1) formed between a tread face (12A) and a groove bottom (16B) to be not more than 5°, water expulsion is performed smoothly in the vicinity of the ground contact edge while securing the rigidity of land portions in the vicinity of the ground contact edge. This enables a high degree of both wet performance and dry performance to be achieved.

When viewed in cross-section orthogonal to a length direction of the lug groove (16): A1 is an area of a region enclosed by an imaginary line (FL3) passing through an end portion on a tread face side of the tread-in side first inclined portion (16Fa) and perpendicular to the tread face (12A), by an imaginary line (FL5) passing through an end portion on a groove bottom side of the tread-in side first inclined portion (16Fa) and orthogonal to the imaginary line (FL3), and by the tread-in side first inclined portion (16Fa); and B1 is an area of a region enclosed by an imaginary line (FL4) passing through an end portion on a tread face (12A) side of the tread-in side second inclined portion (16Fb) and perpendicular to the tread face (12A), by an imaginary line (FL6) passing through the deepest portion of the lug groove (16) and parallel to the tread face (12A), and by the tread-in side second inclined portion (16Fb).
