Thanks, Chris.

By my math, if a 10.5 will work with a ~ .7" negative offset, then putting on a 12 with .75" more tire on the outside of that MIGHT work. That's assuming that I don't run into trouble with the "more" tire on the inside.

That said, my new question: has anyone has run a 33x12 on the "Wide Tire" (7" wide, 0 offset/3.5" BS) rim on the 88-91 with no lift...
