Patent ID: 10647158

Abstract:
The pneumatic tire of this disclosure includes on a tread surface four or five circumferential grooves, and includes a pair of shoulder land portions, a pair of intermediate land portions, and one or a pair of central land portions partitioned thereon, wherein: in a tread widthwise cross sectional view at an unloaded condition when the tire is mounted to an applicable rim and applied with a prescribed internal pressure, when drawing a virtual arc R1 protruding to a tire radial outer side, of which a center of curvature is located on a tire equatorial plain, across four tread widthwise edges adjacent to the circumferential grooves of outlines of the pair of intermediate land portions, a correlation among each protrusion amount t1, t2 and t3 of outlines of the central land portions, the intermediate land portions and the shoulder land portions from the virtual arc R1 satisfies: t1<t2, and t3<t2.
