looks like my 15x10 with 4" backspacing... your tire would be out about 5.5" from the body in the rear with 3" back spacing... it looks like 4'' or 4.5'' backspacing to me

think of it like this, less backspacing = more clearance/ tire getting set out more from the WMS (wheel mounting surface). more backspacing = tires inside the fender wells, hitting control arms, coil springs, sway bar, inner fender guard....

less back spacing = a hurting on your unit bearings.

i want to eventually go with a with a more narrow wheel so i can run less psi and also bring the wheels in a little bit. i have plenty on clearance. i have alot of trimming done and i plan on going with a 33/1050 or 32/1150 so i can stuff them rather then hitting my quarters. so should i go with a 15x8 with 3 bs?
