    摘要： A pneumatic tire (10) is disclosed comprising a carcass (22) and a belt structure (40). The belt structure (40) comprises a plurality of belt layers that include at least one spiral belt layer (60) and at least one zigzag belt layer (70). Each of the at least one spiral belt layers (60) has cords arranged at an angle of 5° or less with respect to an equatorial plane of the pneumatic tire (10) and each of the at least one zigzag belt layers (70) has cords arranged at an angle in a range of from of 2° to 40°, alternatively from 5° to 30°, with respect to the equatorial plane of the pneumatic tire (10) and extending in alternation to turnaround points at each lateral edge of the belt structure (40). A first belt layer of the plurality of belt layers located radially outward of the carcass (22) is one of the at least one spiral belt layers (60). The first belt layer has an axial width less than the axially widest belt layer of the plurality of belt layers. The pneumatic tire (10) further comprises a tread (20) comprising two or more main grooves (17a, 19a, 17b, 19b) extending circumferentially continuously around the pneumatic tire (10) and defining a plurality of ribs (25a, 23a, 21, 23b, 25b) that include an axially outermost rib (25a, 25b) on each lateral side of the tread (20). At 10% to 100% of the rated inflation pressure of the pneumatic tire (10) and no load, each of the two axially outermost ribs (25a, 25b) is radially raised in relation to a respective next nearest rib (23a, 23b) located axially inward of the respective axially outermost rib (25a, 25b).

    摘要： A motorcycle tire includes a tread portion between a pair of tread edges. The tread portion includes a tread rubber forming a tread surface. The tread rubber includes a first rubber layer comprising a first rubber and forming the tread surface, and a second rubber layer comprising a second rubber and being adjacent inwardly in a tire radial direction of the first rubber layer. A loss tangent tan δa of the first rubber at 100 degrees C is smaller than a loss tangent tan δb of the second rubber at 100 degrees C. A glass transition temperature of the first rubber is lower than a glass transition temperature of the second rubber.

    摘要： Provided is a pneumatic tire (10) having a tread (20) including a block (30) in which a waveform sipe (41) is formed. The waveform sipe (41) is formed such that the pitch (P) increases and the amplitude (A) decreases from a block surface side to a block bottom side. The pitch (P) increases towards end sides the block (30) with respect to a center of the block (30) in a tire axial direction (W).
