A pneumatic tire including a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass extending between the bead portions through the tread portion and sidewall portions, wherein the tread portion is provided radially inside the carcass with a tread tape having a thickness of not more than 2.0 mm and having a tensile elastic modulus larger than any rubber existing between the tread tape and the adjacent carcass cords. A method of manufacturing the pneumatic tire includes vulcanizing a main body of the tire, excepting the tread tape, and attaching the tread tape onto the inside of the vulcanized tire main body.
