hmmmm 7 in wide wheel with 11.5 wide tires.......4.5 inches of overhang........NOPE not only is that a risk of in beeding the tire on pot holes but 11.5 will hit all your suspension parts with 4.5 inches if overhang and factory offset and backspacing...just no.
Considering the stock size is 31x10.5, i will say no it does. The 33" tire allows the tire to fit the rim better than a 31x10.5 if anything because it can stretch more.
I have already had a 285/75/16 on a 7" rims
285's measure 11.25".
It was impossible to break the bead, even when at 5psi.
i say go for it the only way you are going to learn is to do it but if the offset and backspacing on the wheel are wrong you will do nothing but scrape on suspension, frame and fender.
