15'' to 16'' wheel swap? Need Help

I have a 99 reg cab 4x4 with 15x7 wheels. Just got 2.5'' coilovers w/ billys all around and 2'' aals in the rear. I want to run 32'' tires but dont want to go much wider than 10.5. After researching i found that there is no 32x10.5x15. What i did find is the 265x75x16 close to a 32x10.5x16.

My question is 'What kind of offset/backspacing would i need to clear all wheel components(calipers, spindle towers, upper ball joint etc...) on a 16x8 wheel and also have minimal rubbing.

Any knowledge or suggestions would be helpful.
Thanks Matt
