Grab a flat piece of metal or a level that covers the entire length of the rim, measure from where the mounting surface to the where the underside of the metal/level.. That is your backspacing.
To calculate offset you'll need the following measurements:
Wheel backspace
Wheel Width
Wheel Center line (outboard flange to inboard flange measurement / 2)
Subtract:
Wheel center line from Wheel backspace to get offset.
If backspace is less than the wheel centerline the offset is negative
If backspace is greater than the wheel centerline the offset is positive
it is just a regular black steelie, but i am thinking of going 4" BS not 3.75". Will this work well with the inch wider rim? Or should i stick with the 3.75?
Plan on 32 X10.5's.
And thanks for the info JD.
