Abstract:
1. A method of assembling a tire and a wheel rim, comprising the steps of: (1) determining a Radial Runout (RRO) value (Wr (2) determining a phase (θc) of a correction unbalance (Wc) found by the following formula (1), by using the RRO value (Wr  θ c =Tan −1 [[Wub ×Sin θ ub +{( Wr 1 × Tt )/(2 ×L )}×Sin θ r 1 ]/[ Wub ×Cos θ ub +{( Wr 1 × Tt )/(2 ×L )}×Cos θ r 1 ]]  (1) (3) assembling the tire and the wheel rim in a state of aligning the phase (θc) of the correction unbalance Wc with the phase (αt) of the light point of the tire.
