Abstract
A rotary drum used in a tire testing machine has a road surface base material made of an aluminum alloy and provided with a road surface onto which a tire is pushed. The road surface is coated with a thermally-sprayed steel film having higher hardness than the road surface base material, and polished. With such a configuration, a favorable test result can be obtained.
