So I'm trying to determine the frequency of a vehicles tire which is 3 ft in diameter, traveling 65 mph.(adsbygoogle = window.adsbygoogle || []).push({});

This is what I have determined so far.

r = 1.5 ft v = 65mph = 95.34 ft/s

circumference = 2*pi*r = 9.42 ft

T = distance/speed = 9.42/95.34 = .0988 so f should be the inverse of that right

so does f = 10.12 hz or rev/s

i found omega to be 607.26 RPM or 63.6 rad/s Am I missing anything. Or just making this too complicated.

suggestions would be appreciated.
