Abstract

PURPOSE: To prevent the convergence of shearing stress on a section tended to be brought into contact with a belt layer and a bead in a carcass by keeping the carcass from being affected by any force other than reaction from the belt layer arranged under the tread section when the tire is filled with air.
CONSTITUTION: A carcass 5 embedded in a tire is so ballanced in shape that a curve from an intersecting point P of a plane A-A including a bead resistor surface Pr roughly perpendicular to the rotary aixs Q-Q of the tire and the carcass 5 to a tread section 1 through a side section 2 cannot substantially be affected by any force other than reaction from a belt layer 7 produced by inner pressure when the tire is filled with air. A section of the carcass from the point P to a bead wire 4 is inverted in the curvature from that of the above curve thereof, and flollows the inside of a limb flange Rf in shape. With such an arrangement, the convergence of shearing stress on the both ends of the carcass curve can be prevented.
