11.5" wide tire on 15x7" factory wheels?

I've researched all over the interweb, and no one has a good answer. I have an '01 with 4.5" RC lift. The previous owner put a set of Soft 8 15x8 wheels with 4" of backspacing. This has become an issue for me for more than one reason. What I want to know is if I can run a 32x11.5x15 tire on a factory 15x7 wheel without any rubbing, issues, or premature tire or sidewall wear

I ran the same way back when, rubbed on the control arms on sharp turns but no big deal.

Same.
