Introduction
The Ferrari 250 GT Series is one of the most iconic Ferrari lineups ever produced, including legendary models such as:
-
250 GT Berlinetta
-
250 GT Lusso
-
250 GT SWB
-
250 GTO
These vehicles defined Ferrari’s golden era of V12 grand touring and motorsport success.
As classic 1950s–1960s Ferraris, the 250 GT models use wire wheels, cross-ply tyres (later radial upgrades), and centre-lock hubs, meaning modern fitment standards differ significantly.
At AUTOSPORT TYREWORLD Adelaide, we provide expert advice for classic Ferrari restorations and safe modern tyre solutions, ensuring both authenticity and performance.
