Master disk, master disk mounting method, and master disk removal method

In a tire removal processing, a clamping step and a tire removing step are executed. In the clamping step, a tire is clamped by an upper support and a lower support by bringing the lower support into contact with a lower side wall of the tire in a state where a lower rim is fitted in the tire and the upper support is in contact with an upper side wall of the tire. In the tire removing step, the tire is detached from the lower rim by relatively moving the lower rim vertically downward with respect to a lower support while the clamping step is maintained.

A tire balance measurement device includes a rotation drive portion, an eccentric force measurement unit, a calculation unit, and an evaluation unit. The eccentric force measurement unit measures an eccentric force generated in a main shaft. The calculation unit calculates an eccentric amount of the main shaft based on the eccentric force measured by the eccentric force measurement unit. The evaluation unit evaluates the eccentric amount of the main shaft based on a correlation between the eccentric force measured by the eccentric force measurement unit when the main shaft is rotated at a predetermined rotation speed, and the rotation speed.
