摘要： A pneumatic tire in which a block formed in a tread surface has, in a ground contacting surface thereof, a closed sipe which is formed so as to not open onto a groove. The sipe has a first opening formed in the ground-contacting surface of the block, a second opening formed at side surfaces of the block, and a hole which communicates the first opening and the second opening. In accordance with this structure, water taken-in into the sipe from the first opening at the ground-contacting surface of the block is discharged to the second opening contacting at the side surface facing to the groove. As a result, water drainability of the sipe is improved without lowering rigidity of the block. Thus, a ground contacting performance of the block improves. The pneumatic tire therefore has improved performance on wet roads and improved performance on snowy and icy roads without the rigidity of blocks decreasing.

摘要： A method of designing a tire which takes into consideration actual conditions in the presence of a fluid, such as drainage performance, on-snow performance, noise performance, and the like. A tire model and a fluid model including the shape, structure, and the like are constructed, and a road surface condition is inputted (steps 100 to 106). Boundary conditions during tire rolling or tire nonrolling are set (step 108), deformation calculation and fluid calculation of the tire model are performed (steps 110 to 114), and a boundary surface between the tire model and the fluid model is recognized to update the boundary conditions (steps 118 and 120). The result of calculation is outputted as the result of estimation, and based on this result of estimation, main travel paths of the fluid, i.e., streamlines, are adopted (step 122), grooves are formed along the determined streamlines so that a tire model with patterns is constructed (steps 124 and 126), and the draft design having satisfactory performance is adopted (steps 128 to 132).

摘要： The ground contact pressure on land portions 44 is uniformed so that drivability is improved and uneven wear is suppressed to improve wear resistance. The parts of the carcass layer 28 and belt layer 33 overlapping with the main grooves 42 are convexly curved toward the outside in the radial direction due to the internal pressure. The reinforcing layer 49 is arranged at the position spaced from the neutral axis of deformation in the compressed side in a certain distance, i.e. radially inside of the radially outermost carcass ply 30, and the steel cords 47 which extend in the direction including the tire width direction and its approximate direction and which act as supports for resisting against the compression force are embedded in the reinforcing layer. As a result, the above-mentioned curved deformation can be effectively suppressed.

摘要： When a single performance or a plurality of antinomical performances are to be obtained, the best mode of a tire is designed under a given condition. A basic shape model using one block as a reference shape is obtained (100). An object function representing a tire performance evaluation physical amount, a constraint condition for restricting the tire shape, and a design variable which is an angle of a wall surface which determines the block shape are determined (102). Next, the design variable is varied continuously by &Dgr;ri to determine a modified shape model (104 to 108). A value of the object function of the modified shape model and a value of the constraint condition are calculated, and a sensitivity of the object function and a sensitivity of the constraint condition are determined (110, 112). A variation amount of the design variable which minimizes a standard deviation of block rigidities is estimated, a modified shape model is determined, an object function value is calculated, and a block shape forming the tire is determined by using the value of the design variable (114 to 120).

摘要： The present invention aims to provide a pneumatic tire for a motorcycle capable of improving turning performance on a wet road surface as compared to that of conventional tires. The pneumatic tire for a motorcycle comprises a tread 28 consisting of a tread central portion having a width of 60% of a tread developed width and tread side portions located outside of the tread central portion in the width direction of the tire and a plurality of wide inclined grooves 42 and narrow inclined grooves 44 inclined at an angle of less than 90 degrees with respect to the circumferential direction of the tire formed in the tread side portion such that the grooves continuously extend over a region of 50% or more of a width of the tread side portion. A groove width of the narrow inclined grooves 44 is set within a range between 0.3 mm and 2.5 mm. A total area of the wide inclined grooves 42 is set to not more than 20% of an area of the tread side portion. Such configuration can satisfy both of drainage performance and block stiffness of the tread contact portion in turning at a high level to obtain a higher grip force in turning on a wet road surface than that of conventional tires.

Of the left and right dissimilar rubber layers (15b, 15c), made of a dissimilar rubber of a smaller tan δ than that of the rubber of a tread surface layer (15a), the width is within a range of 5% to 25% of the extended tread width, the position of the end on the tread edge (15z) side is within a range of 5% to 14% of the extended tread width as measured from the tread edge (15z), the position of the end on the center region (17) side is within a range of 15% to 30% of the extended tread width as measured from the tread edge (15z), and the thickness is 20% to 70% of the whole thickness of the tread. Also, the tan δ of the rubber constituting the left dissimilar rubber layer (15b) disposed on the more frequently used left side is smaller than the tan δ of the rubber constituting the right dissimilar rubber layer (15c) disposed on the less frequently used right side.
