Hi, Ben. I'm probably running about the same suspension as you with 34" LTB's. I'm running steel rims w/ 4" of BS. My rubbing issues have more to do with the fender flares than I think you would have on stock rims. You may have troubles with the wheel wells though. fyi- LTB's are loud, hard to balance, and HEAVY.
8-track, gun rack, spittoon, gimbal mounted beer buoy, blah, blah, blah, blah......
