A shield for a rim of a vehicle wheel for covering a rim during treatment of a tire mounted on the rim includes a panel that is circularly shaped and rigid. The panel is dimensioned such that the panel is configured to abut to a rim of a vehicle wheel to substantially cover the rim while leaving a tire attached to the rim exposed for treatment. A brace is pivotally coupled to the panel proximate to a center of the panel. The brace is configured to extend between the panel and a surface upon which the vehicle wheel rests, retaining the panel in abutment to the rim of the vehicle wheel. The improvement is the brace positioned on the panel, allowing the panel to be retained in abutment to the rim without further action by a user.
