First responder has hashed his units. The correct result: the circumference of the tire is 0.58 pi meters, the speed is 17 meters per second, so the rotation speed is 17/(0.58 pi) revolutions per second. The point at the top edge of the tire is moving at 34 meters per second.

58 cm / 17 m/s = 3.41 per second. There are sixty seconds in a minute so 3.41 * 60 = 205 per minute.
