Abstract: A pneumatic tire comprises a tread portion provided with a band layer disposed radially inside a tread rubber provided with a first circumferential groove. Cords of the band layer are a hybrid cord formed by twisting together a first filament and a second filament having an elastic modulus lower than that of the first filament. In a region radially inside the first circumferential groove, a maximum thickness t1 of topping rubber on the radially outer side of the band cords is not more than 1.0 mm; a minimum distance d1 from the bottom of the first circumferential groove to the radially outer surface of the band layer is not more than 2.0 mm; and a distance d2 from a groove edge of the first circumferential groove to the radially outer surface of the band layer is not more than 15.0 mm.

Abstract: A tire includes a tread portion 2. A middle land portion 7 of the tread portion 2 has a first middle lateral groove 11. The first middle lateral groove 11 includes a first groove portion 31, a second groove portion 32 inclined in the same direction as the first groove portion 31, and a third groove portion 33 located between the first groove portion 31 and the second groove portion 32 and inclined relative to a tire axial direction in a direction opposite to that of the first groove portion 31. The first groove portion 31 has a groove width increasing from the third groove portion 33 toward an outer side in the tire axial direction. The second groove portion 32 has a groove width increasing from the third groove portion 33 toward an inner side in the tire axial direction.

Abstract: A pneumatic tire includes a tread portion having a first tread edge, and a first buttress portion extending inwardly in a tire radial direction from the first tread edge. The first buttress portion is provided with a plurality of protectors protruding outwardly in a tire axial direction. The plurality of protectors includes a set of protectors including a first protector and a second protector arranged adjacent to the first protector via a groove extending in the tire radial direction. The groove is provided with a tie-bar connecting the first protector and the second protector. The tie-bar is partially formed in a tire radial region of the groove, and the tie-bar has a protruding height that is smaller than a protruding height of the first protector and a protruding height of the second protector.
