Yup. I was thinking of CapriRacer, too. And I still suspect that the BMW i3's super-narrow & super-tall OEM tire/rim is a sign that some portion of the benefits of wider can be accomplished with larger diameter while avoiding the aero penalty of greater width. The i3 has what 19" wheels with like a 145 or 155 tire?

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
