You start the car.
Check your power steering fliud, if it is low this could cause the vibration you are feeling.
Is the steering lock on? Jiggle the wheel when you turn the key.
Vibration of the tire is caused by a uniformity parameter called "variation of radial force". Usually a vehicle's steering wheel will vibrate (called torsional nimble) at a certain speed. This vibration is caused by the harmonics of this radial force. Picture the side view of a tire with different size springs within it. The force of these springs cause a distortion of this force and you feel this distortion in the steering wheel.
