<p>A pneumatic tire capable of suppressing the occurrence of heel and toe wear in shoulder blocks while well maintaining water-discharge property and traction performance until the last of the wear. The shoulder blocks (13) forming shoulder block rows (12) are partitioned by both side main grooves (3), tread ends, outer side lug grooves (9), shoulder lateral inner side sipes (10), and shoulder peripheral side sipes (11) connecting the shoulder lateral inner side sipes (10) to the outer lug grooves (9). The shoulder blocks (13) adjacent to each other in the tire peripheral direction complement their rigidities each other by the sipes to suppress the deformation of the tire so as to increase partial wear resistance. Also, since a timing at which the shoulder blocks (13) tread on a road surface and a timing at which the shoulder blocks (13) kick off the road surface are displaced between tread end side parts and a tread center side part and the displacement arrests their movements each other to suppress the deformation of the shoulder blocks.</p> |
