PROBLEM TO BE SOLVED: To provide a tire for a two-wheeled automobile tire which can exhibit sufficient grip force.SOLUTION: A tire for a two-wheeled automobile is equipped with a tread 4 of which an external surface forms a tread surface 20, and the tread 4 has a center region 22 including an equator face EQ in a tire axial direction, and a pair of shoulder regions 24 which are positioned both outer sides of the center region 22. Each shoulder region 24 has a reinforcement layer 34 of plural strips extending in a direction inclined with respect to the equator face EQ, and a coating layer 32 which covers all reinforcement layers 34. A rubber strength Hsc of the center region 22 is higher than a rubber strength Hss of the coating layer 32 in the shoulder region 24, and a rubber strength Hsr of the reinforcement layer 34 is higher than the rubber strength Hss of the coating layer 32.
【課題】グリップ力を十分に発揮しうる二輪自動車用タイヤの提供。【解決手段】その外面がトレッド面20をなすトレッド4を備えており、このトレッド4が、タイヤ軸方向において、赤道面EQを含むセンター領域22と、このセンター領域22の両外側に位置する一対のショルダー領域24とを有しており、各ショルダー領域24が、赤道面EQに対して傾斜した方向に延在する多数条の補強層34と、全補強層34を覆う被覆層32とを有しており、センター領域22のゴム硬度Hscが、ショルダー領域24の被覆層32のゴム硬度Hssより高くされており、補強層34のゴム硬度Hsrが、上記被覆層32のゴム硬度Hssより高くされている。【選択図】図1
