A method and apparatus for assembling a tire with a disc wheel under the optimum condition, in which inner diameter variation of the disc wheel, radial force variation of the tire proper, radial force variation of a wheel assembly body and existing assembled condition are displayed on separate channels of a display device, respectively. The radial force variation of the tire proper thus displayed is phase shifted by an angle at which the radial force variation of the wheel assembly body becomes minimum. The tire is then displaced with respect to the disc wheel by the above angle so as to obtain the optimum assembled condition.

An apparatus for assembling a tire with a disc wheel comprising means for rotating a wheel assembly body composed of a tire and a disc wheel assembled with each other for several rotations under a loaded condition; means for electrically measuring and memorizing radial force variation of the wheel assembly body and inner diameter variation of a disc wheel proper during the rotation of the wheel assembly body; means for deriving radial force variation of a tire proper by subtracting the inner diameter variation of the disc wheel proper from the radial force variation of the wheel assembly body and memorizing the radial force variation of the tire proper; means for effecting electrical simulation so as to relatively phase shift the inner diameter variation of the disc wheel proper and the radial force variation of the tire proper; means for determining the optimum assembled condition of the wheel assembly body by effecting a phase shift between the inner diameter variation of the disc wheel proper and the radial force variation of the tire proper and determining the amount of the relative phase shift; and means for correcting the assembled condition of the wheel assembly body on the basis of the amount of phase shift thus determined.
