Component Rotational Speed Calculation: Notes
NOTE:
Tools Required: Electronic Vibration Analyzer (EVA) 2 (J-38792-A).
A size P235/75R15 tire rotates one complete Revolution Per Second (RPS), or one Hz, at a vehicle speed of 5 MPH. This means that at 10 MPH, the same tire will make 2 complete revolutions in one second, 2 Hz, and so on.
