  • Method of wheel manufacture for correcting rotational non-uniformity of a pneumatic tire and wheel assembly and apparatus for performing such method
    Patent number: 4354407
    Abstract: A method of punching a wheel for a pneumatic tire and wheel assembly manufactured with mounting holes offset from the geometric center to locate the low point of the first harmonic of radial runout adjacent a given angular location, such as the valve hole, so that, when a tire is mounted thereon with the high point of the first harmonic of radial force variation aligned with the valve hole, the respective harmonics cancel each other to provide a tire and wheel assembly with enhanced rotational characteristics. In an apparatus for forming the wheel mounting holes by axially reciprocating a piercing tool against a wheel disc while the bead seats are clamped between wheel locating jaws, axially opposed jaw pairs are centered on an axis offset from the axis of reciprocation such that the centerline of the mounting holes is correspondingly eccentrically offset from the average bead seat axis.
    Type: Grant
