PURPOSE: To prevent plating corrosion by supporting a vehicle while axle moment load is externally being applied to the wheel bearing through a tyre.
CONSTITUTION: The tyre 2 is loaded on the pressurizing tool 4a which slides in the axle shaft direction of the tyre 2 on the bed 3a and the lower part of the tyre 2 is pressurized inside. The axle moment load is loaded to the wheel bearing of the tyre 2, as shown by dashed lines. By setting the moment load to the size which prevents fretting corrosion, the plate corrosion and Brinell identation can be avoided.
