if factory on a 91 z offset is 0 front and +16 rear what would that be in backspacing exactly?

Here's an easy way to figure it out. I just went thru this buying wheels for my 4x4 truck.

An 8" wide rim actually measures 9" from outside edge to outside edge. (Advertised rim widths are determined from measuring the distance between the inner beads)

So, an 8" wide rim with "0" offset will have 4.5" of backspacing. Next, there are 25.4mm to an inch, so 6mm is equal to about .2" (let's call it 1/4"), 12mm is equal to about .5" ...and so on.

Based on that, 16mm should be close to 5/8 or .625". Now, a +16mm offset should yield about a 5.125" backspace. I'd call it 5.25" to be safe.

One last thing to remember is that positive offset will increase backspace, while negative offset will decrease backspace.

Hope this helps.

 

can't believe i missed that on skulte's website...

very nice above indeed. thanks guys.
