<p>The invention provides a pneumatic tire which prevents a belt end from separation and is improved in uneven wearing performance. A buttress region is provided with first and second transverse line grooves extending from buttress vertical grooves extending along the periphery of a tire toward the inner side of the axial direction of the tire. The inner end of each first transverse line groove is closer to the inner side of the axial direction of the tire than a tire tread grounding rim, and a tail end is formed in a tire shoulder vertical strip. The inner end of each second transverse line groove enables a tail end to be formed in a position of being closer to the outer side of the axial direction of the tire than the tire tread grounding rim. The tire shoulder vertical strip includes vertical cutter groove columns and vertical cutter grooves. The vertical cutter groove columns are arranged to be a line at intervals along the periphery of the tire via vertical cutter groove sheets extending peripherally among the first transverse line grooves. The vertical cutter grooves pass between the vertical cutter groove columns and the outmost vertical grooves and extend along the periphery of the tire.</p> |
