When did you last see one of these rare Mobilgas Mobiloil metal tire inserts? These 16.5-inch tire inserts are seldom seen in the wild, so here is your chance to own one! Tire inserts were very colorful and vivid, which drew attention to the tire on display at the service station. Mobil service stations used this tire insert in a Mobil tire as a sales tool for the brand. The colors and gloss on this metal insert are very sharp. Some scratches are on the piece, along with some minor bends in the upper right area of the curve. The reverse side retains the original tabs, which have been bent a few times to grip the inside of the tire. 21175-QPPP
