A sectional width SW (mm) and an outer diameter OD (mm) of the tire satisfy a predetermined relational expression. At least one noise reducer is provided on an inner surface of the tire. The noise reducer is provided at least in the center region and the shoulder region. Among thicknesses of the noise reducer measured in a direction perpendicular to the inner surface of the tire, a maximum thickness Ts in the shoulder regions is larger than a maximum thickness Tc in the center region.

A pneumatic tire comprises a tread portion which has, on each side of the tire equator, a first tread edge, a second tread edge and a third tread edge which are occurred under tire loads of 100%, 75% and 50% of a regular tire load, respectively. Between the third tread edge and the tire equator, a circumferentially continuously extending main groove is disposed. A shoulder region between the main groove and the first tread edge is provided with a first inclined groove which extends so as to intersect with the first tread edge, the second tread edge and the third tread edge. The depth of the first inclined groove at the first tread edge is smaller than the depth at the second tread edge and the depth at the third tread edge.

Provided is a tire for a motorcycle for uneven ground traveling capable of continuously exhibiting good grip performance. The tire for a motorcycle for uneven ground traveling includes a tread part on which plural crown blocks are formed, and at least one of the crown block has a wheel tread, a first side surface, a first edge arranged between the wheel tread and the first side surface, a concave part that opens on the wheel tread and the first side surface, and a second edge arranged between the wheel tread and the concave part. The wheel tread has at least one external corner part in which an angle between the first edge and the second edge is an acute angle.

A pneumatic tire includes at least four circumferential main grooves extending in a tire circumferential direction and at least five land portions defined by the at least four circumferential main grooves. A center land portion includes a plurality of center lug grooves extending through the center land portion in a tire lateral direction and disposed at predetermined intervals in the tire circumferential direction, and a plurality of center blocks that are defined by the plurality of center lug grooves. The center blocks each include a narrow shallow groove that extends through the center block in the tire lateral direction and that remains open when the tire comes into contact with the ground.

A motorcycle tyre for traveling on rough terrain, the tyre includes a tread portion provided with blocks. The at least one of the blocks includes a ground contact surface having a pair of lateral edges extending in a tyre axial direction. The at least one of the blocks is provided with a pair of lateral narrow grooves extending in the tyre axial direction on the ground contact surface to form a pair of edge-side portions defined between the pair of lateral narrow grooves and the pair of lateral edges.
