The entrepreneur and Formula V driver saw a need for aluminum wheels. Wirth thus became one of the pioneers of light alloy wheels on the global market. The first factory was opened back in 1978 in France. In 2007 Ronal AG purchased Italian wheel manufacturer Speedline, which covers the commercial vehicle segment including trucks, trailers and buses. This helped the group expand into the racing and Formula 1 sectors as well as into weight-optimized flow forming technology. 83 FIA titles have been won on Speedline Corse wheels. In 2012, Ronal expanded its range to include forged wheels with the majority stake in Fullchamp in Taiwan.
