Try swapping your front and rear alloys - you might just be shifting the problem from the front to the back, but it may stop the steering wheel wobble and give you some clues as to the cause.
The steering wheel wobble I experienced on my old Focus was down to a buckled alloy, which looked fine from the outside and even passed a couple of MOTs, but the flat spot was pretty severe when viewed from the inside and gave a definite bulge to the tyre, which was visible when the wheel was spun.
