Hey all, i have a ZR2 blazer, 2.5" suspension lift and 2" BL. Im going with a 33 12.5 15 MT tire, i need help with the backspacing of the rim and what i should running? i want the tires to stick out enough to make it more aggresive but not to much 2-3". Would a 4.5" BS on a 15 X 8 rim work or would a 15 X 10 with a different BS work better?
Thanks in advance for the help!!!

 

4.5 backspace would have you stick out about 4 in with the 15x10 (front)
1.25 spacer in rear would have the rear stick out the same amount

you may have rub issues with a 33

question for you... why would you want to run a 12.5 tire on a 15x8?
