Provided is a motorcycle tire (1) for traveling on rough terrain, the tire having a block (10) provided to a tread section (2). The block (10) has the following: a block lateral surface body part (15) that extends straight from the edge of a tread surface (12) inward in the tire radial direction; and a skirt section (20) that connects the block lateral surface body part (15) and a groove bottom surface (9). The skirt section (20) has the following: a flat section (21) that extends in a straight line on the groove bottom surface (9) side; and a curved section (22) that connects, in a beveled arc, the area between the flat section (21) and the block lateral surface body part.

Claims6

Dependent claims

A motorcycle tire for running on rough terrain comprising:

a tread portion provided with a plurality of blocks protruding from a virtual block bottom which extends along a groove bottom;
in a block cross section passing a center of gravity of a ground contact surface of the blocks and being perpendicular to the virtual block bottom, the blocks comprising a block-sidewall main portion extending radially inwardly in a straight shape from an edge of the ground contact surface and a skirt portion that connects the block-sidewall main portion to the groove bottom;
and
the skirt portion comprising a planar portion extending in a straight shape on the side of the groove bottom and a curved portion so as to connect the block-sidewall main portion to the planar portion in a chamfered manner.
