    摘要： A pneumatic tire for a two-wheeled vehicle, including a pair of sidewalls, a tread, a carcass, bead rings embedded in radially inner ends of the pair of sidewalls and stiffeners including tapered rubber fillers. According to the invention, the tire comprises a belt layer between the tread and the carcass. The belt layer consists of at least one ply whose width is at least 0.5 time of a width of the tread. Cords of the ply have a modulus of elasticity of at least 600 kg/mm.sup.2 and are arranged substantially in parallel with an equatorial plane of the tire.The tire according to the invention maintains a hoop effect of the belt layer to sufficiently exhibit characteristics as a radial tire and eliminates an extreme difference in bending rigidity in radial directions over from the tread to the sidewalls to obtain smooth turning of the two wheeled vehicle at a corner.

    摘要： A heavy duty pneumatic radial tire comprises a tread continuous at its round-shaped shoulders with sidewalls and formed with a plurality of main tread grooves extending circumferentially thereof. The tread is formed with a circumferentially extending narrow groove in zigzag in each end zone of contact surfaces of the shoulders with a road surface under a standard load. The zigzag grooves have a width of 15-30% of that of the main tread grooves, an amplitude of 0.5-2.0% of the tread width and a pitch of 2.0-7.0% of the tread width. Each of the shoulders is formed in its side surface with a series of intermittent circumferential caved portions, such that a distance in an axial direction of the tire between the deepest bottoms of the caved portions is 105-110% of the tread width and the deepest bottoms are located in a circle having a diameter less than that of a circle passing through the bottoms of the main tread grooves. With the arrangement, the tire according to the invention does not cause any irregular wear at the shoulders and can reduce and prevent the railway wear and growth thereof toward the center of the tread, so that the wear-resistance of the tire is remarkably improved.

    摘要： A pneumatic belted tire for use in motorcycles is disclosed, which comprises a toroidal carcass, a tread superimposed about a crown region of the carcass at a width corresponding to the maximum width of the carcass and provided on its surface with a tread pattern, and a belt arranged on the crown region over the width of the tread and composed of plural rubberized layers each containing inextensible cords inclined at an angle of not less than 30.degree. with respect to the equatorial plane. In this type of the tire, the inclination angle of cords in the belt gradually enlarges within a range of 7.degree.-20.degree. from the center of the crown region toward the tread side edge, and the tread is provided on each side edge portion with a substantially continuous rib having a width corresponding to 5-25% of the tread width.
