wheel spacers/ offset wheel question

I'm sure this gets asked a lot but I'm trying to figure out how much offset would be equal to a 1.25" wheel spacer. I've looked all and can not seem to find the answer I am looking for.

 

This is a vague question and all depends on your current wheel size/offset and what you are trying to achieve? Are you trying to run larger tires on stock wheels? Larger tires (32, espec. 33's) on aftermarket wheels usually have a backspacing of 4.25-4.5" (offset of 0.) on an 8"wide wheel. 33's on stock rims will require 1.25" spacers to acheive the BS listed above to clear. Of course it will also require a lift of some sort along with some trimming and possibly a cab mount chop(depends on the stated variables)

 

I'm going with a 17x9" wheel and running 285/70/17 which I believe comes out to be about a 32 or 33.

 

Aftermarket wheel with a BS of 4.5" (0 offset) should work fine for that tire size. That should clear the UCA's and may need some minor plastic trimming at full lock, probably the front plastic behind bumper.

 

can someone please explain backspacing and offset real quick like? pretend im five.
