How about just get 3.75" back spacing. Thats what most of us run and have no issues on or offroad, and alot of us run commonly 31's to 35's all on 15"x8" rims with 3.75" backspacing. I will not get into the whole geometry in it but there are many many threads on the thought/question of the supposed overstress with different back spacings.

By 3.75 do you mean the 4.5 backspacing that most people run?
