    Abstract: This invention relates to high-speed radial tires, and more particularly to radial tires wherein the thickness ratio (Gc-Gs)/Gc, that is the ratio of the difference between the crown tread thickness Gc, which is a thickness of the tread on the equator of the tire, and the shoulder tread thickness Gs, which is a thickness of the tread of the ground contact surface at the outer edge in direction of the tire axis, to the crown tread thickness Gc is set to be 0 or more and 0.8 or less. By setting the ratio within a range of 0 to 0.8, the force Fs acting in the radial direction on the tread shoulder part, out of the total load acting to the tire, is decreased, thus, the deformation in the bead part is diminished and the permanence in the bead part can be improved. In a tire having the ratio of 0 to 0.8, by setting the angle of the belt cords to be 0 to 20 degrees, it can be used for aircraft and by setting the angle of the belt cords to be 20 to 40 degrees and the aspect ratio to be 60% or less, it can be used for high-speed passenger cars.

    Abstract: A radial tire having a carcass extending from a tread through sidewalls to a bead core in each of two bead parts and turned up around the bead cores. The tire includes a belt layer disposed on the outside of the tire in the tire radial direction of the carcass in the tread portion and a cut breaker disposed between the carcass and the belt layer. Each carcass ply has cords that are buried in topping rubber and arranged independently in parallel to each other within the same plane without linking wefts. In a region from the bead bottom to the turned up end of the carcass, the distance between cords in adjacent carcass plies is within a range of 1/4 to 2 times a diameter K1 of the carcass cord.

    Abstract: A high speed tire for heavy duty vehicles comprise a belt layer of a carcass with radial structure, wherein a profile of the outer circumference of the tire in the specified internal pressure state satisfies that the maximum width and radius ratio Ro/W is not more than 0.54. At this point, the ratio Ro/W is defined as the ratio of the radius Ro of curvature of the arc which passes through maximum width point C, a reference point Q and an intermediate height point M to tire maximum width W. The maximum width point C is defined as a point where the tire width is maximum W. The reference point Q is defined as a point which is apart from the bead bottom line by the length of 0.2 times the total sectional height H of the tire. And the intermediate height point M is defined as a point which is intermediate between the maximum width point C and the reference point Q.
