Lamborghini Miura Tires
The Miura was first revealed as a chassis only, wearing Borrani wheels and 205VR15 Pirelli Cinturato CN72 tires, happily both are still available for your car!
When low profile tires entered the scene in 1969 Lamborghini shifted to a 215/70x15 at the front and a 225/70x15 at the rear, again, both sizes are available from Michelin and Pirelli.
The later SV used cast wheels and 215/70VR15 Pirelli Cinturato CN12 at the front and 255/60VR15 Pirelli Cinturato CN12 at the rear.
