Abstract
A method for assembling a tire on a wheel without causing any detrimental deformation of bead portions of the tire. The tire is obliquely arranged on a wheel cap-shaped jig provided on the upper side surface of the wheel located on a flat surface to arrange the lower part of the lower bead portion loosely around the wheel. The lower part of the tire is inwardly urged, while the other part of the lower bead portion is radially outwardly expanded to arrange it along its circumference around the wheel, progressively. Moreover, the part of the upper bead portion is radially outwardly expanded and is urged downward toward the support surface to arrange it loosely around the wheel. The part of the tire corresponding to the part of the upper bead portion is inwardly urged, while the remaining part of the upper bead portion is radially outwardly expanded and is urged downward toward the support surface along the circumference of the upper bead portion to arrange it around the wheel, progressively.
