so I went to a tire shop with one of the X3 wheels to ask if they could balance it only on the outside portion of the inner portion of the rim. They said no problem - it won't be quite as acurate as using an inner and outer weight, but should balance just fine.

So at this point I am leaning towards sticking with these wheels despite the tight clearance. I really need to put one rim on there again without the weight to make sure there is enough clearance.
