Ferrari 512 Berlinetta Boxer Tyres

  • The first of the 512 Berlinetta Boxer cars of 1976 fitted 7.5”X15” Wheels and 215/70 WR 15 Michelin XWX the front.
  • Unlike the earlier 365 GT/4 BB the 512BB had wider 9” rear wheels with 225/70 WR 15 Michelin XWX until 1981.
  • Our period Innertube Guides suggest that the 512 Berlinetta Boxer was released on wheels suitable for tubeless tyres. Providing your wheels are OE and in good condition, you do not need innertubes on these wheels.
  • 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.
  • In 1981 Ferrari added the fuel injection and 415mm Wheels and 240/55R415 Michelin TRX tyres to the BB512i.
  • Tyres with a profile below 70% (e.g 240/55R415 Michelin TRX) cannot fit innertubes.
  • The front Wheels of the 512BBi were 180mm and the rears 210mm. However, the Ferrari BB 512i fitted 240/55VR415 TRX front and rear until 1984.
  • Ferrari Berlinetta Boxer 512i tyre pressures are suggested to be 45psi for both the front and the rear.

Ferrari 512BB and 512BBi Wheels

Ferrari 512BB on Michelin XWX

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.
