Any tire shop will be able to pick up on a wheel or tire error. If the wheel/tire is asking for to much weight. The tech will then road balance the tire, and the road balance will find any imperfections. Then allow you to correct them; with various methods; e.g.. Re-locate tire. I remember reading something about the steering linkage or stabilizer causing steering wheel vibrations. Can't remember the exact term but its cheap, and a common issue with crossfires. I will do more digging. Its not a wheel tire issue...
