Okay, after completing the 100 other things on my list, I went down and had a look at walmart. They had one of those application charts, and then I had a thought.

If I just measure the stock backspacing, and get a wider set with the same backspacing, they should fit fine, right? The offset would be totally different, but that shouldn't matter much, as I'll just be filling out the fenders, but probably not enough to rub.

I think my stock wheels are 14x6, but I'm not sure. The van came with a set of 225/14s, I don't know the sidewall offhand. If the 225s work now without rubbing, and I get a set of wheels with the same backspacing, but in 16x7", and the same overall tire height, the tire should take up the same space as with the 14" rim, right? Correct me if I'm being a blithering idiot please.
