    摘要： A pneumatic tire with a low aspect ratio of 0.55 to 0.70 comprising a tread provided with four circumferential grooves disposed symmetrically about the tire equator plane to divide the tread into axially spaced five land portions, at least one of the five land portions having a set of lateral grooves crossing the land portion. A sea area ratio Ss/S of a total area Ss of grooves to a total area S of a tread surface is 0.20 to 0.27. A distance La from the tire equator plane to the inner groove edge of the inner circumferential groove among the four circumferential grooves is 0.090 to 0.125 times a tread width TW, and a distance Lb from the tire equator plane to the inner groove edge of the outer circumferential groove among the four circumferential grooves is 2.5 to 3.0 times the distance La.

    摘要： A pneumatic tire comprises 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 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 comprises: 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.
