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 t of topping rubber on the radially outer side of the band cords is not more than 1.0 mm; a minimum distance d 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 d 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.
