Stick w/ 5. 5"-6" backspacing and no more than a 9" wide wheel w/o problems.
Centerlines I believe have a few to choose from w/ a reasonable price.
To answer your question. They should fit OK w/ 33" tires, but like bob4x4 said. They will stick out roughly 2". Not my flavor either, but some like it. Any tire bigger than 33". Then refer back to what I wrote in paragraph one above.
