<p>PROBLEM TO BE SOLVED: To provide a motorcycle tire for running in a rough terrain exerting an excellent running performance on both of soft road and hard road.SOLUTION: A crown block 21 and a middle block 41 are arranged in a position where at least a part of respective wall surfaces face each other in tire axis direction. The crown block 21 has a horizontally long rectangular shape in which the width in tire axis direction is larger than the length in tire circumferential direction. The tread of the middle block 41 has an approximately pentagon shape comprising: an inner side 45; a pair of axis-direction sides 46 extending to outside in the tire axis direction while tilting in a direction in which the length in the tire circumferential direction, of the tread 44 on the middle block 41 from the inner side 45 is gradually increased; and a pair of outer side 47 extending to outside in tire axis direction while tilting in a direction in which the length in the tire circumferential direction, of the tread on the middle block 41 from outer end 46o in tire axis direction, of the a pair of axis direction sides 46 is gradually decreased. At least a part of the tread of the middle block 41 contacts with the ground in a regular load state.</p> |
