Abstract
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.
