- If you want innertubes for these tyres the Michelin 15/17H will provide the best fit.

- Tyre pressure for the early Ferrari BB 512, we suggest 36psi in the front and 39psi in the rear.

Ferrari 512BB and 512BBi Wheels
The wheel situation with the Ferrari Berlinetta Boxer classic cars can be a little confusing.
The first Berlinetta Boxer, the 365GT/4 BB had 7” wheels front and rear, with 215/70VR15 tyres front and rear.
When they upped the engine size from 4.4 litres to 4.9 litres and called the car the 512 BB they maintained the same front 215/70 VR 15 tyre on the same size 7” wheel. However they fitted a very wide 9” wheel on the rear with a 225/70 VR 15 tyre. Both the 7" and the 9" wheels have Borrani wire wheel fitment options (see below).
Then when they updated to the BB512i with fuel injection and millimetric Michelin TRX classic tyres, they continued to have different size front and rear wheel widths (180mm front & 210mm rear) however they did fit the same size 240/55VR415 Michelin TRX vintage Ferrari tyres.
Confusion can be caused because the continuation, if you like, the next rear engine 12 cylinder classic Ferrari to take over from the Berlinetta Boxer 512i was the Ferrari Testarossa. The Testrossa carried on with millimetric TRX wheels, this later generation of Ferrari, did also fit a larger rear wheel than the front wheel. However unlike the 512BBi, the Testarossa did have different size front and rear tyres.
