Abstract
Apparatus and method for manufacturing a vehicle wheel rim and disc assembly with controlled lateral runout characteristics, as well as the resulting wheel and a pneumatic tire and wheel assembly having overall improved ride characteristics. The method and apparatus of the invention contemplate fixturing of a preformed rim so that the average plane of the rim bead seats is at preselected orientation with respect to the axis of interference pressfit of a preformed disc therein, and thus at preselected orientation with respect to the wheel mounting plane defined by the inboard disc surface. In one implementation of the invention, the average bead seat plane is made nominally parallel to the wheel mounting plane by selective adjustment of the fixturing bead seat locators, so as to minimize lateral runout of the resulting wheel. In another implementation of the invention, the average bead seat plane is intentionally angulated with respect to the disc mounting plane so as to locate a peak of the first harmonic of lateral runout circumferentially adjacent to a selected location on the wheel rim, such as the rim valve hole. In the latter implementation, the wheel so formed may be assembled to a pneumatic tire which is pretested and marked to identify location of a complementary peak of the first harmonic of lateral force variation, so that the respective harmonics are out of phase and tend to cancel each other, and thereby obtain overall improved ride in the tire and wheel assembly.
