Abstract: A tyre for a motorcycle for rough terrain comprises a tread portion. In a region between at least one of tread edges and a tyre equator, the tread portion is provided with middle blocks, shoulder blocks, and tie bars each connecting between one of the middle blocks and its adjacent one of the shoulder blocks. The shoulder blocks include first shoulder blocks forming the one of the tread edges and second shoulder blocks arranged on an inner side in a tyre axial direction of the one of the tread edges. The tie bars include first tie bars each connecting between one of the middle blocks and one of the first shoulder blocks and second tie bars each connecting between one of the middle blocks and one of the second shoulder blocks.

Abstract: In a tire 2, each crown block 22c has a laterally extending shape that is longer in an axial direction and shorter in a rotation direction. A top surface 32c of the crown block 22c includes a crown front edge 46c. The crown front edge 46c has a bottom BC located on a heel side with respect to both ends thereof in the rotation direction. Of the crown front edge 46c, a portion connecting the bottom BC and each end forms an inclined edge 54c extending from the bottom BC to the end and inclined to a toe side in the rotation direction. The inclined edge 54c of the crown front edge 46c includes at least three edge components 58c.

Abstract: A tire 1 for motorcycles comprises a carcass 6, a belt layer 7, and a tread rubber 2G. The belt layer 7 includes at least one reinforcing cord coated with rubber and spirally wound. In a meridian section passing through a tire rotational axis of the tire 1 in a standard state, a width BW of the belt layer 7 in a tire axial direction is in a range of from 60% to 80% of a tread width TW. The tread rubber 2G has a thickness at a tire equator (C) in a range of from 70% to 90% of thickness at tread edges (2t).
