Abstract: A tire for running on rough terrain for which an intended tire rotational direction is specified, comprises: a tread portion 2 provided with a first block 11 having a ground contacting top surface 16, and a base cross sectional shape 17. The ground contacting top surface 16 has a polygonal shape having a heel-side oblique edge 21 inclined with respect to the tire axial direction. The base cross sectional shape 17 is a polygon having a heel-side axial edge 22 extending in the tire axial direction. In the top view of the first block, an angle θa formed between the heel-side oblique edge 21 and the heel-side axial edge 22 is in a range from 5 to 45 degrees.
