Tyre Diameter: 16, Profile: 50, Width: 225/50 | Porsche 930 Turbo 1975 to 1977

The original 3 litre turbo 911. Built from 1975 to 1977. Originally fitted with a 205/50VR15 radial front tyre and a 225/50VR15 rear. There was the option of 205/55VR16 front and 225/50VR16 rear tyres on 16 inch rims in 1977.

A new concept in supercars on its release, the Turbo rapidly became a "thing" for Porsche (even its Taycan EV has a Turbo spec) and the world of 80s motoring. Offering the same performance as much more expensive cars, with race-proven technology, and not a little terror-related machismo, this car made Porsche's long-term motorsport led marketing look like genius.
