Backspace/Offset?????
I have an 87 Ramcharger I'm about to lift 8 inches. I just bought some Super Swamper Radials size 37x12.5x16.5. I need to know if anyone knows or had experience on how much offset/backspace I need on my new rims so the tires won't rub while turning or interfere in general. PLEASE HELP!!!!

Yea Back spacing is from back of the center of the rim to the edge of the rim, Offset is from the front of the rim in the center to the edge of the rim... rightCLRracer said:how much lift do u have? also, do u know the difference between offset and backspacing? not trying to be rude, just dont want u to be confused by the answers given.

?Backspacing is the distance from where the rim physically mounts to the inside bead edge. Offset is the distance between where the rim physically mounts to the center of the rim widthwise.
EG: A 10" wide rim with 4" backspacing has 1" offset. (I forget the convention for positive or negative offset, I believe this is positive offset)
An 8" wide rim with 3-1/2" backspacing has 1/2" offset.

SM got it, although i cant remember if it is positive or negative offset either. anyway, 3.5-4 is what most people run, but the more lift u have the farther out u can go.

And don't forget, the higher the offset the more stress you are putting on your axle bearings and front u-joints, steering components, lugs, etc. If you can, try not to go over 1-1.5" offset. Most factory rims have zero offset, for durability.

Typically fwd cars use positive offsets and rwd trucks etc use negative offsets.
