Borrani wire wheels were the standard for the early Ferraris until the introduction of the cast alloy wheels on the 275 and 330 models. The wheels were made under license of the English company Rudge-Whitworth until the early 1950s when the name Carlo Borrani was adopted. In 1961 the company was sold and the markings were changed to Ruote Borrani. The Knock-off hub caps were manufactured by a company outside of the wheel factory and the old stock of Carlo Borrani hub caps was used up sometime in early 1963 before they were changed to the Ruote Borrani stamping also.
