It's also a skinny tire. It's only 5.60" through the sidewall, whereas a 185 is
7.28". My calculations were based on an aspect ratio of 82%, which might not be
correct.
But I did find a road test from Nov 1967 Road & Track that claimed 2730 engine
rev/mi in 5th. Working backwards from that gives 866.0 tire rev/mi and a tire
diameter of 23.28".
