Sorry, don't remember the brand. Here's a pic of one mounted on my stock 20 inch tire. What's backspace?

 

As opposed to offset which is the dimension between center line of wheel and hub face, back space measures between inside rim and hub face. The less back space you have, the farther out the wheel and tire sit, giving more clearance for things like chains. You can figure that clearance by offset AND width but back space is simpler. I asked about the brand and model of wheel cause I'm having a hell of a time finding one that works. Thanks
