Tires out of balance
It is the engine that is vibrating and it is just being felt in the steering wheel. Can be a vacuum leak, or miss in the engine.
If it is vibrating on the steering wheel, you may need an alignment. If it is vibrating at the tire area you may have a bent wheel or need to have your tires check, take it to any tire shop and they can test. I had the same problem and it was a bent wheel.
Your rims are bent and/or your alignment is off. Bent rim, bad tire, loose suspension/steering component.
