Abstract
Provided are a method and a device for fixing a run-flat support body to a pneumatic tire. The method and the device can achieve the prevention of unevenness in the distribution of the lubricant applied to the inner surface of the tire in which the run-flat support body is used, and thus of deterioration in the weight balance of the wheel. In the fixing method, the run-flat support body configured of a pair of elastic rings to be arranged around a rim and an annular shell installed across these elastic rings is fixed to the pneumatic tire which is to be fitted to the rim with the run-flat support body inserted into a hollow part of the tire. The fixing device, for restricting the radial movements of the run-flat support body inserted into the hollow part, is fitted to at least one of bead parts of the pneumatic tire before the pneumatic tire is fitted to the rim so as to coaxially hold the pneumatic tire and the run-flat support body.
