wheel offset question

[nortex]

im buying wheels sunday and need to know what the diff would be between a 20x8.5 +12 and a 20x8.5 +25

All other things being equal, the wheels with +12 offset would stick out about a 1/2" more and give you about 1/2" clearance inside.

you shouldnt need a +25 on a 8.5" wide as that is more of a front wheel drive. the +12 should be fine if your lowering it as the +25 would suck it in a whole 1/2" extra inside the fender.

The offset on those wheels are definitely a positive number, most likely a +25 or larger and the backspacing is probably 5" or larger. Just a guess. Remember, backspacing is measured in inches, offset in millimeters.

The backspacing comes into play too. The backspacing is just the measurement from the mounting point on the wheel (laying the outside of the wheel on the ground) to the edge of the wheel. As backspacing decreases, offset increases (in the negative direction) and vise versa. Stock 16"x7" wheels are somewhere around +28 to +31 offset. Check out the 2nd posts in both threads.

Those probably have a 5.25" back space. Maybe 5.5". That's what is used most commonly on square bodys
