No. A revolution is a revolution is a revolution. Two wheels of different diameters can have the same rotational velocity (in rpm) or angular velocity (in radians per second or degrees per second). Mark the outer edge of the wheel, and count the number of full revolutions it makes in one second. But I have a feeling your question is poorly worded. You should realize that a smaller wheel will rotate faster than a larger one for a given linear velocity. For example, if you are riding a bicycle, say, with a small wheel on the front and a large one on the back, the smaller front wheel will need to rotate faster -- that is, it's angular velocity will be greater -- than the larger back wheel.
