I have another backspacing question for all the experts. I have read on several threads that the stock backspacing is 5.5". I just measured my 18" 2008 wheels and they are 6". Is this what everyone is seeing on the 2008 models?

 

It's actually 5.5, the measurement is to the bead surface, not the back edge of the rim. I asked the same question a few weeks back and someone posted a great link that describes all the different characteristics of wheel dimensions. I'm sure they'll probably add the link here for you too.

 

Here you go.
