What size (width/backspacing) rims are you running on your factory 2wd Burb?
 

My dad has a Burb like mine except his is on the factory chassis with (what I believe to be) factory ride height.

His Burb (the burgundy one) has 20" rims on it right now, but we are thinking about swapping them out for something with a different look.

I was thinking the Boss 338's with the gray centers. Can anyone share what rim width/backspacing they are running?
