The invention relates to a tire for running on uneven ground, which can improve traction performance on the uneven ground. A tire (1) for running on rough terrain is provided with a tread portion (2). The tread portion (2) is provided with pattern blocks (4) protruding from a tread base portion (2R). The pattern block (4) comprises a first side wall surface (11). The first side wall surface (11) includes: an outer portion (13) extending in a straight line and inclined toward a rear landing side in a tire rotation direction N; and an inner part (14) which is bent into an arc shape and connects the outer part (13) and the tread base part (2R). The length (H1) of the outer portion (13) in the radial direction of the tire is 30-70% of the height (Ha) of the pattern block.
