Anybody know the backspacing on a stock wheel?

I want to run 20x10s with a 4.5 backspace but I am concerned that they will stick way outside the fender flares.

Yes, 20 X 10's will stick out--also depends on tire size as mnetioned above.

Do not put a 15.5 wide tire on a 5.5 backspace---you will have problems on the inside of the tire.

Here are 18 X 10, 4.5 backspacing with 38-15.5 tires--they do stick out---there is another psot on this of late. You can do a search for it.
