Introduction
The Ferrari 225 Series represents a key step in Ferrari’s early V12 evolution, bridging the gap between the 212 and the legendary 250 lineup.
Models such as the 225 S (race-focused) and 225 Inter (road-going GT) continued Ferrari’s tradition of combining motorsport performance with coachbuilt luxury.
As a classic Ferrari from the early 1950s, the 225 Series features wire wheels, cross-ply tyres, and bespoke engineering, meaning modern tyre and wheel standards do not directly apply.
At AUTOSPORT TYREWORLD Adelaide, we provide expert guidance for both modern performance vehicles and classic Ferrari restoration fitment, helping maintain authenticity and safety.
