A couple years before Enzo died, there was a TV tire commercial which asked "Why do Ferraris come with Firestone tires? Because Mr. Ferrari wants it that way." and then showed a picture of Enzo smiling.
It was Goodyear, specifically the Eagle VR50. The advertisement featured a Ferrari 308 GTB.
Ferrari had only adopted radial tires in racing a decade earlier. I'm curious as to what deal they got with Goodyear at the time, as radial tires (including high performance versions) were already long ubiquitous in the United States by the time that commercial came out, which I believe was actually after the end of the 308's production run.
(I don't recall if it was Firestone or Goodyear.)
