Will these fit?

I have a 99 silverado bagged on 20's my truck is finally getting painted in the next few weeks and would like to upgrade to 22's.  The wheels im looking at getting are boss 330's. Will they fit in the rear they are 22x9 with +32 offset and 6.25 backspacing and for the front the 22x9's with +20 offset and 5.75 backspacing.

you can check it yourself if you know the current specs of your 20s. since i'm assuming the 20s tuck now just use the link and find out where the new rims will sit http://www.1010tires.com/WheelOffsetCalculator.asp
