Answer engine summary
What should Adelaide drivers know about Ferrari 166 Series Tyre Size, Wheel Specs, PCD, Centre Bore & Torque Guide | Adelaide?
Adelaide drivers should match tyre choice, wheel fitment and service timing to the vehicle placard, actual driving use and local conditions. Hot SA roads, wet winter braking, Adelaide Hills corners and country touring can all affect tyre wear, grip and comfort, so professional fitment, pressure setup, balancing and wheel alignment matter as much as the tyre product choice itself.
Introduction
The Ferrari 166 Series represents the early evolution of Ferrari road and race cars, following the 125 S. Models such as the 166 Inter, 166 MM, and 166 Spyder played a major role in establishing Ferrari’s reputation in motorsport and grand touring.
Unlike modern vehicles, the Ferrari 166 Series used bespoke engineering, wire wheels, and period-correct cross-ply tyres, meaning modern tyre sizing standards do not directly apply.
At AUTOSPORT TYREWORLD Adelaide, we understand both modern performance vehicles and classic Ferrari heritage fitment, offering expert advice for restorations and collector vehicles.

Historical tyre size references
-
Early wheel specifications
