摘要： Driving stability and durability is efficiently improved.Since a protecting layer 43 embedded with reinforcing cords 41 is disposed between a tread 35 and a belt reinforcing layer 31, both of the protecting layer 43 and the belt reinforcing layer 31 decentrally bear a large bending force generated when a pneumatic tire 11 runs on a sharp projection or a difference in level. As a result, even if reinforcing elements 33 in the belt reinforcing layer 31 are extended by large tension due to fill internal pressure, increase of strain generated in the reinforcing elements 33 can be effectively suppressed.

摘要： In a pneumatic tire for a front wheel, turning performance on a wet road surface is improved compared with a conventional tire.In a pneumatic tire for a front wheel 10, a tread shoulder region 28S extends from a tread edge 20E toward a tire equatorial plane across a width of 20% of a developed width of a tread 28, and a land portion 56 defined by lateral portions 50 is disposed at the tread shoulder region 28S. Regarding the land portion 56, a wall surface 56K of the land portion at a trailing side is parallel to the tire radial direction; a wall surface 56H of the land portion at a leading side inclines from a groove bottom toward a groove opening, and an angle thereof relative to the tire radial direction is 35 degrees. It is effective especially for circumferential leaning deformation of the land portion 56 when braking force acts thereon, whereby lifting of an edge of the land portion at the leading side arisen from the tilting deformation can be suppressed. This makes it possible to secure a contact area with a road surface and in combination with drainage effect through the lateral groove 50, to improve turning performance on a wet road more compared with that of a conventional tire. In addition, on dry road, turning performance can also be improved.

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.

摘要： In a pneumatic tire for a motorcycle where grooves 30, 31 (inclined portion 32) extending generally in a width direction are formed on an outer surface of a tread portion 13 and a rotational direction is designated, driving performance or braking performance is improved. Driving force affects on a tire for a rear wheel during accelerated running, so that an entire land portion 35 between the inclined portions 32 is about to lean backwardly in the rotational direction. However, the inclined portion 32 is generally inclined forwardly in the rotational direction from a deepest point D toward an opening end K, so that a support portion 36 formed at a rear end of each land portion 35 in the rotational direction and having a substantially triangular shape strongly resists the leaning, thereby effectively suppressing the leaning of each land portion 35. As a result, grip force during driving is improved, thereby improving driving performance. And at the same time, ground-contact pressure is equalized, thereby suppressing non-uniform wear.
摘要翻译：在用于摩托车的充气轮胎中，指定在胎面部13的外表面上形成有沿宽度方向延伸的槽30,31（倾斜部32）和旋转方向，提高了驱动性能或制动性能。驱动力在加速行驶期间对后轮的轮胎产生影响，使得倾斜部32之间的整个陆部35围绕旋转方向向后倾斜。然而，倾斜部32通常从最深点D朝向开口端K沿旋转方向向前倾斜，从而形成在各凸台部35的后端的旋转方向上的支撑部36，该支撑部36具有大致三角形形状强烈地抵抗倾斜，从而有效地抑制每个陆部35的倾斜。结果，提高了驾驶时的抓地力，从而提高驾驶性能。同时，接地压力相等，从而抑制不均匀的磨损。

摘要： The ride comfort and driving performance of a pneumatic tire 11 are improved while maintaining the high-speed durability and steering stability, in which an inclination angle A of steel cords 26, 27 in all belt plies 24, 25 constituting a belt layer 23 is not less than 45° with respect to an equator S of the tire, and a belt reinforcing layer 35 embedded with reinforcing cords substantially in parallel to the equator S is arranged between a belt layer 23 and a carcass layer 18, whereby an out-of-plane bending rigidity of the belt layer 23 in a circumferential direction can be lowered to make a longitudinal spring constant of the pneumatic tire 11 and uniformize the diameter of the belt reinforcing layer 35, and further a deformation amount of a tread portion 15 having a high bending rigidity can be made small.

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： A pneumatic tire for a two-wheeled vehicle has further increased driving stability, particularly in turning. Pneumatic tire 10 for a two-wheeled vehicle has belt layer 16 and tread section 18 that are sequentially arranged on the outer side, in the radial direction of the tire, of a crown section 14C of a carcass 14. On the belt layer 16 is placed a spiral belt layer 20 formed by spirally winding a band-like rubber coated cord layer so as to form a cord angle in the range of 0° to 5° relative to the circumferential direction of the tire. With L the tread surface distance from tire center CL to tread edge T, spiral belt layer 20 is present only in the range of 0.65 L to 0.85 L from tire center CL, and intersecting belt layers 22A-22D are arranged in the range of from an edge in the lateral direction of the spiral belt layer 20 to tread edge T. Intersecting belt layers 22A-22D include organic material fiber cords intersecting with each other and having a cord angle of from 30° to less than 75° relative to the circumferential direction of the tire.

摘要： Auxiliary grooves 28 are formed in land portions 26 so that the wet performance is improved by the increase in the edge factors of the auxiliary grooves 28 and by the water absorbing actions of the auxiliary grooves 28. Since the auxiliary grooves 28 are arranged on the shorter diagonal lines of the land portions 26, the land portions 26 are divided into two triangles approximating equilateral triangles so that the reduction, as caused by providing the auxiliary grooves 28, of the rigidity of the land portions 26 can be suppressed to the minimum. As a result, the deformation of the land portions 26 is suppressed to maintain the dry performance.
