A rim mounting device configured in such a manner that, even if a permanent magnet breaks due to impact produced during mounting thereof by magnetic attraction, the rim mounting device can be handled easily after the breakage of the permanent magnet. The rim mounting device is provided to a tire testing device having a spindle for rotating a tire and is adapted that a rim is mounted to the tip of the spindle. The rim mounting device is provided with: a rim mounting section provided to the tip of the spindle, having a rim mounting surface capable of making contact with the rim, and having mounting recesses formed in the rim mounting surface so as to be arranged side by side; permanent magnets inserted in the mounting recesses, respectively, and generating magnetic force for attracting the rim to the rim mounting surface; and scatter suppressing members.
