Introduction
The Ferrari 340 Series marked Ferrari’s move into larger-capacity V12 engines, with models like the 340 America and 340 Mexico built for endurance racing and high-speed grand touring.
As early 1950s Ferraris, these vehicles feature bespoke chassis engineering, wire wheels, and cross-ply tyres, meaning modern tyre sizing and fitment standards do not apply.
At AUTOSPORT TYREWORLD Adelaide, we provide expert support for both modern performance vehicles and classic Ferrari restoration projects, helping maintain authenticity while ensuring safe tyre solutions.
