摘要： A motorcycle tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass extending between the bead portions in a toroidal manner. Each of the sidewall portions is provided with a sidewall rubber. In each of the sidewall portions, a minimum thickness (Ts) is 50% or less of a minimum tire thickness (Ta) from a respective one of tread edges to a tire inner cavity surface. A minimum thickness (Ds) of the sidewall rubber is from 0.3 to 1.9 mm.

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： A pneumatic radial tire for passenger vehicles that satisfies a defined relationship between sectional width SW and outer diameter OD of the tire and includes one or more circumferential main grooves extending in a tire circumferential direction on a tread contact surface. A negative ratio of a half portion of the tire on a vehicle-mounted outward side, which is one side of the tire in a tread width direction with the tire equatorial plane as a boundary, is greater than a negative ratio of the other half portion of the tire on a vehicle-mounted inward side, which is the other side of the tire in the tread width direction with the equatorial plane as the boundary. A drop height (or ground contact length relationship, or tread gauge relationship) is also defined.

摘要： A pneumatic tire comprises a tread portion, a pair of sidewall portions, a pair of bead portions, a carcass extending between the portions, and an inner rubber extending between the portions, on the inner side of the carcass. The inner rubber comprises a first portion extending through the tread portion with a first thickness and a second portion extending through the sidewall portions with a second thickness smaller than the first thickness. The land ratio of the tread portion 2 is 65% or more.
