OK, I'm going to be getting some fabtech spindles, it says that you can run 32/11.5x15 with 3 3/4" BS. now, if I'm thinking right, I can run 35/12.5x15 with 4 3/4" BS, or is it 2 3/4" BS?

I know I've seen several folks on here running 35's with the fabtech spindles, so any help would be appreciated.

 

The smaller BS the farther it will stick out. You have a better chance of fitting bigger tires with a smaller BS. I've never seen a rim with under 3" of backspacing though.

 

3 3/4" back spacing is what im running and its just about perfect imho... you can run 12.5 wide tires with no problem too
