LJ rims are 0 offset, but they still hit the front springs at full lock even with 1 inch spacers (but not as bad without spacers).
7.50 16 fit OK on 6.5(?) Vit rims, but you would have to run 2 inch spacers because of the +25 offset.

I've seen 7.50s on 7 inch rims but they looked at bit funny, too much sidewall sticking out, plus the tyre shop didn't want to fit them to 7inch rims but was OK with 6.5s, go figure.
