ABSTRACT:
A phase θc of a correction unbalance found by the following formula (1) is determined by using a Radial Runout (RRO) value Wr1in a primary component of the RRO of the wheel rim, a phase θr1(unit: °) of a peak position thereof, an unbalance level Wub of a heavy point of the wheel rim, a phase θub thereof, a distance L of a balance weight sticking position, a weight Tt of the tire, and a phase αt of a light point of the tire. The tire and the wheel rim are assembled in a state of aligning the phase θc of the correction unbalance with the phase αt of the light point of the tire.in-line-formulae description="In-line Formulae" end="lead"?θc=Tan−1[[Wub×Sin θub+{(Wr1×Tt)/(2×L)}×Sin θr1]/[Wub×Cos θub+{(Wr1×Tt)/(2×L)}×Cos θr1]]  (1).in-line-formulae description="In-line Formulae" end="tail"?
