ABSTRACT:
The radial pneumatic tire of this invention has a reduced bead mass and improved rolling resistance. This is accomplished with less than a 5 percent reduction in the ability of the tire to sustain nominal loads and maintain tire endurance. The bead area has a profiled single bead filler that extends radially outward from the apex portion with an essentially constant thickness portion and a tapered portion. An outer filler strip extends from a point radially inward of the design rim flange near the bead core radially outward to a position near the mid height of the tire when the tire is mounted on the rim. The end result is a tire with smaller standard architectural components but very efficient load supporting and endurance capabilities. In one embodiment the outer filler strip extends radially outward beyond the radial extent of the single bead filler. In an equally effective embodiment the single bead filler extends radially outward beyond the radial extent of the outer filler strip. The total bead mass is reduced by as much as 15 percent and rolling resistance is reduced by as much as 5 percent for the reduced bead mass tire of this invention.
