Help - vibrations from front end on new 14s not there with the 13s on

I picked up a wobble when I went from my 13" wheels to 14 inch MOPAR ralley wheels. I have had them balanced twice and the front end checked out, it is mostly new. One thing that I have wondered is whether the later ralley wheels (still 5 on 4) might have been set up for larger lugs than my 7/16 and that it might be possible of have the wheels not center correctly. The wheel holes do not look all egged out. I did get some tapered closed lug nuts new for these wheels. I am not running washers on the lug nuts. The comments on the weights brushing the control arm is very possible. If they hit very hard you will really notice it and it won't only be at low speeds. Now that they use steel weights instead of lead the weights won't "self clear". Assuming the wheel lug holes are not egged out and that the wheels are are not bent or tires separated something has to be moving around. What about some liquid or fix a flat in the tires? Last comment, a rear wheel out of balance can feel like a front wobble. The difference is you won't be feeling it in the steering wheel like an out of balance front tire. The balance it on the car comment is a good one. I can't find anyone who does that around here. My wobble is very mild and at just about exactly 32 mph. I am going to try some of the suggestions here.
