Introduction
The Ferrari 275 GTS is the open-top grand touring variant of the 275 series, designed with a stronger focus on comfort and cruising compared to the more aggressive 275 GTB.
Featuring elegant Pininfarina styling and a smooth V12 engine, the 275 GTS is a classic Ferrari convertible that blends performance with luxury.
As a mid-1960s Ferrari, it uses wire wheels, early radial tyres, and centre-lock hub systems, meaning modern tyre fitment standards differ significantly.
At AUTOSPORT TYREWORLD Adelaide, we specialise in both modern performance vehicles and classic Ferrari restorations, ensuring correct fitment, safety, and authenticity.
