摘要： A motorcycle tyre comprises a tread portion (2) curved convexly such that the maximum cross section width TW of the tyre lies between the tread edges (E), a carcass ply (6) of cords arranged radially at an angle of 70 to 90 degrees to the tyre equator, and a belt ply (7) of at least one cord laid at an angle of 0 to 35 degrees disposed radially outside the carcass ply (6) in the tread portion. When the tyre is mounted on a standard rim and inflated from 10 % of a standard inner pressure to 100 % thereof, the tread portion swells such that the amount of swelling is larger in a shoulder region than a crown region of the tread portion. The carcass cord tension Tcs in the shoulder region is 2.0 to 3.8 times the carcass cord tension Tcc in the crown region, and the belt cord tension Tbs in the shoulder region is 1.2 to 2.0 times the belt cord tension Tbc in the crown region.

摘要： A pneumatic tyre comprises a tread-sidewall reinforcement (6a,7a,7b) extending between the tyre sidewall portions (4) through the tread portion (2) which has a symmetrical cord arrangement to prevent ply steer. The tread-sidewall reinforcement is made of a series of loops of at least one reinforcing cord (11)which loops spread over the circumference of the tyre. The tread-sidewall reinforcement can be formed as a carcass or a reinforcing layer disposed outside a carcass. When viewed in the radial direction, the inclination angle θ of the reinforcing cord with respect to the tyre circumferential direction is substantially 90 degrees at the tyre equator and decreases to substantially 0 degree gradually from the tyre equator towards the bead portions. When viewed in the axial direction, the inclination angle of the reinforcing cord with respect to the radial direction is in the range of from 60 to 90 degrees.
摘要翻译：一种充气轮胎包括通过胎面部分（2）在轮胎侧壁部分（4）之间延伸的胎面侧壁加强件（6a，7a，7b），胎面部分（2）具有对称的帘线布置以防止帘布层转向。胎面侧壁加强件由至少一个加强帘线（11）的一系列环形物制成，所述加强帘线线在轮胎的圆周上展开。胎面侧壁增强件可以形成为布置在胎体外部的胎体或增强层。从径向观察时，补强帘线相对于轮胎周向的倾斜角度θ在轮胎赤道处大致为90度，并且从轮胎赤道向胎圈部分逐渐减小至大致0度。从轴向观察时，补强帘线相对于径向的倾斜角度在60〜90度的范围内。

摘要： A thin gauge, fine diameter steel cord reinforced tire ply fabric (2) is disclosed which can be effectively lap spliced without detrimental effect. The steel cord (1) has one or more filaments (9), each filament has a percent elongation of over 2.5 % and tensile strength of at least (-2000D + 4400 MPa) x 95 %, where D is the diameter of the filament in millimeters. For passenger and lightly loaded trucks the fabric (2) is manufactured using a preferred cord (1) which is a 1 + 5 x .18 mm wire spaced 14 ends per inch, for heavier loaded vehicles such as light trucks load rated E or greater the number of cords (1) is increased to 28 ends per inch. The fabric (2) used as a single radial ply for a pneumatic tire (20) can be spliced using a lap splice technique due to the strength and fineness of the cord (1) in combination with the very thin gauge (g) between the adjoining surfaces (10).

摘要： The pneumatic tire has a single carcass ply reinforced with parallel metallic cords, each cord composed of at least one filament having a tensile strength of at least (-2000 x D + 4400 MPa) x 95 %, where D is the filament diameter in millimeters. The turnup portion of the single carcass ply (12) in the bead portion of a pneumatic tire is interposed between the bead core (11) and a toe guard (18), and the radially outer edge of each turnup portion being in contact with the main portion of the carcass ply and extending to an end point 0.5 to 4.0 inches (12.7 to 101.6 mm) radially outward of the bead core as measured along the main portion of the carcass ply of the tire. A toe guard (18) associated with each bead core (11) has a first and second end and each end is disposed directly adjacent to the carcass ply. The first end (18a) of the toe guard is located on the axially inner side of the main portion of the carcass ply at a location about 0.4 to 3.5 inches (10 to 89 mm) radially outward of the bead core as measured along the main portion of the carcass ply and the second end (18b) is located at a point ranging from substantially the axially outermost point of the bead core (11) to a location about 3.5 inches (89 mm) radially outward of the bead core as measured along the turnup portion of the carcass ply. The first end (18a) and second end (18b) of the toe guard is a shorter distance from the bead core than said end point (12a) of the turnup portion of said carcass ply.
