Offset is measured from the center, backspacing is measured from the edge of the wheel to the mounting surface.

20x12's wtih a -44 will require a 6" lift if you don't want to cut anything.

I want to fit 20x12 -44 on 33x12.5 and I don't know much about backspacing...

Your going to have some major rubbing issues if you do t go with a 6" lift. Esp if u don't want to trim.


Weren't yours 35" boggers?? they are much taller than any other 35" tire i have ever seen.

My Boggers where 37's. But that's not what I was talking about. I had some 35/11.50r15 BFG all-terrains and they only measured 34" and they rubbed bad.

Here's a different Tahoe with 20x12 & 33's with a 6" lift, looks like he only trimmed the air dam.
