摘要： A pneumatic tire having an aspect ratio of not more than 55% and comprising: an axially protruding rib provided on each side of the tire to overhang a flange of a wheel rim; a carcass extending between bead portions through a tread portion and sidewall portions; a belt disposed radially outside the carcass; a tread rubber disposed radially outside the belt to define the ground contacting surface of the tire; a sidewall rubber disposed on each side of the tire and extending from the tread portion to the rib along the axially outside of the carcass; a clinch rubber disposed on each side of the tire and extending from the bead portion to the rib along the outer surface of the tire; and a wing rubber disposed axially outside the sidewall rubber and extending from the tread rubber to the rib along the outer surface of the tire, the wing rubber being softer than the tread rubber. In a tire meridian section, in a region defined between 45% and 70% of the tire section height, every boundary line between rubber layers which include the tread rubber, sidewall rubber, clinch rubber and wing rubber at least, intersects neither the outer surface of the tire nor the outside of the carcass.

摘要： A pneumatic tire including a carcass containing a ply of cords defining the innermost reinforcing cord layer extending between bead portions, and an airtight layer disposed inside the cords of the carcass ply along the inner surface of the tire, covering substantially the entire inner surface of the tire, wherein the airtight layer is made of air-impermeable rubber including at least 10 weight % of halogenated butyl rubber and/or halogenated isobutylene-paramethyl styrene copolymer in its rubber base, and the thickness of the airtight layer measured from the inner surface of the tire to the cords of the carcass ply is in a range of from 0.2 to 0.7 mm.

摘要： A pneumatic tire comprises a circumferential groove disposed in the axial center of the tread potion, circumferentially spaced main grooves disposed on both sides of the tire equator, the main grooves extending axially outwardly beyond the tread edges, while inclining to one circumferential direction and increasing the inclination angle of the groove center line with respect to the circumferential direction, auxiliary grooves each disposed between the circumferentially adjacent main grooves and extending from a middle portion of one of the main grooves towards the above-mentioned circumferential direction beyond the tread edge, each of the auxiliary groove having a part being equidistant from the adjacent main grooves and having a length more than 30% of the length of the auxiliary groove. The intersecting angle .beta. of the auxiliary grooves with the main grooves is in the range of from 20 to 60 degrees.
