充气轮胎
摘要：
一种充气轮胎(10)，其胎肩陆地部(42)具备：形成在沿轮胎周向延伸而设置在接地端(E)的轮胎宽度方向内侧(Wi)的细沟(60)与胎肩主沟(36B)之间的主体陆地部(421)，主体陆地部具备：与沿轮胎周向而设置的胎肩主沟(36B)邻接的接触区域(421A)、以及沿轮胎周向(C)而设置在细沟与接触区域之间的非接触区域(421B)。接触区域是在正规载荷状态下与路面接触的区域，非接触区域是：轮胎宽度方向外侧(Wo)以在细沟呈开口的方式而向比胎面表面更靠轮胎径向内侧凹陷，且在正规载荷状态下不接触路面的区域。当非接触区域的沿轮胎宽度方向的长度为W1，主体陆地部的沿轮胎宽度方向的长度为Rw时，0.2Rw≦W1≦0.5Rw。
摘要（英）：

The invention provides a pneumatic tire (10), and a shoulder land portion (42) includes a main body land portion (421) formed between a thin groove (60) extending in a tire circumferential direction on a tire width direction inner side (Wi) of a ground contact end (E) and a shoulder main groove (36B), and the main body land portion (421) includes a contact region (421A) adjacent to the shoulder main groove (36B) provided along the tire circumferential direction and a non-contact region (421B) provided along the tire circumferential direction between the thin groove (60) and the contact region(421A). The contact region contacts a road surface in a normal load state, and the non-contact region is recessed to a tire radial direction inner side from a tread surface. The non-contact region does not contact the road surface in the normal road state, and when a length of the non-contact region is W1 and a length of the main body land portion both along the tire width direction is Rw, 0.2Rw<=W1<=0.5Rw.
