What is backspacing?

Hey all, I keep seeing "backspacing" mentioned here and included in the description of new wheels. What is it and what does it do? Thanks for any and all info...

See attached photo for how to measure. My 17X9 DC-1's have 4.5 inches of backspacing. The lower the number, it will be more of a deep dish rim. Most factory rims have a higher numerical backspacing.

So the lower the #, the further out from centerline the wheel will be centered, therefore the deeper the dish. Gotcha. Thanx for the info!

Yeah, basically, wheels w/ 4.5" BS will stick out 1" further than the stockers, giving a more aggressive stance and the ability to run wider tires without rubbing.
