And the traction performance and the operation stability performance on the uneven ground are improved. A tire (1) for running on rough terrain is provided with a tread portion (2). The tread portion (2) is provided with crown blocks (5), middle blocks (6), and grooves (7). The crown pattern block (5) includes a tread surface (10) and a first wall surface (11) located on a first landing side in a tire rotation direction (R). The first wall surface (11) is inclined toward the rear landing side in the tire rotation direction (R) from the tread surface (10) toward the inner side in the tire radial direction. The axial length La of the groove part (7) is 5%-70% of the axial length Lm of the middle pattern block (6).

    提高不平整地面上的牵引性能以及操纵稳定性能。不平整地面行驶用轮胎(1)具有胎面部(2)。在胎面部(2)设置有胎冠花纹块(5)、中间花纹块(6)和沟部(7)。胎冠花纹块(5)包含踏面(10)和位于轮胎旋转方向(R)的先着地侧的第一壁面(11)。第一壁面(11)随着从踏面(10)朝向轮胎半径方向的内侧而向轮胎旋转方向(R)的后着地侧倾斜。沟部(7)的轮胎轴向的长度La为中间花纹块(6)的轮胎轴向的长度Lm的5%~70%。
