The present invention provides a motorcycle tire (2) for running on rough terrain, which can improve traction performance without impairing durability. A tire (2) is provided with a tread (4). The tread (4) is provided with a plurality of blocks (18). The plurality of blocks (18) includes a plurality of central blocks (28) located on the equatorial plane. The plurality of center blocks (28) include main center blocks (28m) having a center of gravity (CG) of the land surface (20) within the land surface (20). At the center of gravity (CG) of the land surface (20) of the main center blocks (28m), the axial length (a) of the main center blocks (28m) is at least twice the circumferential length (b) thereof. The hardness of the main center blocks (28m) is 70 or less. The main center blocks (28m) have a 300% modulus of 8.5 MPa or more.
本发明提供能够提高牵引性能而不损害耐久性的不平整地面行驶用的摩托车用轮胎(2)。轮胎(2)具备胎面(4)。胎面(4)具备多个花纹块(18)。多个花纹块(18)包括位于赤道面上的多个中央花纹块(28)。多个中央花纹块(28)包括主中央花纹块(28m),该主中央花纹块(28m)在陆地面(20)内具有陆地面(20)的重心(CG)。在主中央花纹块(28m)的陆地面(20)的重心(CG)处,主中央花纹块(28m)的轴向长度(a)是其周向长度(b)的两倍以上。主中央花纹块(28m)的硬度为70以下。主中央花纹块(28m)的300%模量为8.5MPa以上。
