How far will my tires stick out?

Hey guys this is my 2nd post on TW since buying my tacoma and I had a question about some wheels and tires as well as a lift I was thinking about getting. I was looking at getting pro comp series 51 in 15x8 with 3.75 bs and a 3" fabtech basic coil over lift as well as some 32x11.5x15 BFGs down the road. I currently have the stock 15x7 wheels with 31x10.5x15 BFGs and I was wondering how far those pro comp rims would make my tires stick out past the fenders. I was researching this earlier and I guess the 1" wider rim with the .75" more bs from stock (4.5" i think) would make the current 31" tire stick out 1.75" right? When I get the 32x11.5x15 tire will it stick out 2.25 inches past the fender since the tire is 1" wider? Would this setup work and look good? My goal is to have the tires stick out 1.5" from stock just like if I put a 1.5" wheel spacer in there. Any help or advice would be greatly appreciated, Thanks!

 

look at the offset of the wheel. thats what makes it stick out. backspacing just tucks it under the wheel well
