Yes and Yes on tires and T-Bar crank, there are many people that have a similar setup on there with no rubbing. I believe that the stock backspacing on the Rangers is close to 4" but not sure. Seeing hose most guts go 3.25" pr
3.75 and the sit out further.
Quoted from Bob in another post
Backspacing on a 7" wheel with +12mm offset is ~4.5 (factory Ranger)
