Does anyone know the offset of my wheel?

I have Pro-comp La Paz 16x8 4.5" of back spacing g but I don't see a + or - number... I have 285/70/16 on my 2015 2wd with Maxtrac spindles and the tire is less than 1/2" of the spindle. Trying to figure out the offset.

 

+0

 

8 inch wheel with 4.5 bs should be -12

 

0 would be 4 inch bs no?

 

No, other way around, 8" -12 is 4" bs.

 

4.5" backspace is 0mm offset on an 8" wide wheel. That's what mine are.

 

You have to use wheel width(outside/9"), not rim width(inside/8").
Manufacturers only list rim width; you have to account for thickness of the flanges...1/2"+1/2"=1".

So....0 offset.

 

There you go OP, 0.
