[Healeys] High rpm's plus COOLING UPDATE

[Richard Hosmer]

Mike,

I believe you are correct so far as the resting imprint is concerned, and
that the nominal computed circumference is "close enough" at modest speeds -
however, at very high speed the tire will have "expanded" enough to make a
small difference in theoretical MPH calcs. I also suspect that this effect
is significantly less with our modern radials than it used to be with the
bias-ply Roadspeeds.
