  • Radial tire
    Patent number: 5388626
    Abstract: A radial tire which mitigates reactions when running across protrusions to thereby avoid damage to the vehicle. The tire prevents rim touch, an indirect contact of the inner face of the tread portion with a flange of the rim or a direct contact of the tread portion with the bead portion. The tire has sidewall portions which are bulged-out to satisfy certain equations. An increase in sidewall thickness and carcass rigidity is avoided with the radial tire.
