In the present invention, an .alpha. value is introduced as indicating the properties of the car and the tread rubber of the tire is selected according to the .alpha. value. Accordingly, the present invention provides a radial tire which comprises a tread and sidewall, wherein the tread has the claimed relation between a viscoelasticity (tan .delta.) peak temperature (Tp) and an .alpha. value which indicates the properties of a car, and a one side half width (w/2) of 25.degree. C. or less, the one side half width (W/2) being defined with respect to a viscoelasticity distribution curve as the distance along the 1/2 peak tan .delta. viscoelasticity line from the perpendicular line representing (Tp) to the intersection with the viscoelasticity distribution curve to the right of the perpendicular line.

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.

Abstract: The present invention relates to a radial tire and a radial tire-rim assembly. The radial tire (1) has a pair of beads (2), each bead having a bead core (3) and a bead apex (5), a carcass (4), with both edges thereof folded back around said bead core and fastened to said bead core, a tread (6), a belt layer (7), and an aspect ratio smaller than 60%. The tread is wider (in the axial direction) than the maximum width of said carcass and the edges of said tread are positioned within a range of 50-100% of the height of the cross-section of the carcass. This structure provides the tire side with rigidity and permits the tread to deform so that is supports the weight of the car and runs safely even when the tire pressure is decreased.
