Document Type and Number:
WIPO Patent Application WO/2014/038378
Kind Code:
A1
Abstract:
In order to improve uneven wear resistance and wet road performance, a pneumatic tire, having a symmetric tread pattern, comprises: a circumferential narrow groove (5) that is formed with a groove depth shallower than a circumferential main groove (3) and extends in the tire circumferential direction and within a range of 40 to 60 [%] of the tire width direction measurement of a lateral rib (41) from one side of the lateral rib in the tire width direction, where a center main groove (31) is the circumferential main groove on the tire equatorial plane (CL), and the lateral rib is a rib (4) adjacent to either side of the center main groove in the tire width direction; and a tire-width direction narrow groove (6), a plurality of which are disposed in the tire circumferential direction, that is formed with a groove depth shallower than the circumferential main groove and is provided extending in the lateral rib while intersecting with the tire circumferential direction, with one end linked to and terminating in the circumferential main groove that is adjacent to the lateral rib on the exterior side in the tire width direction and the other end linked to and terminating in the circumferential narrow groove.
