2005 chevy silverado x-cab need wheel dimensions to tuck and drive

  can anyone help me with the dimensions for me to buy 22s for my truck,
 
  the truck has a 4/6 drop and i want to be able to drive with the 22s now so i need the right dimensions, but in a few months, the truck will be bagged
 
any help would be apreciated.

On my 01 gmc i had 22x10s with a 7.25 backspace.

I'd run a higher offset like a +30

i got an 05 chevy crew and i was runnin a 22x10 with a 16mm offset with a 5/7 drop. it rubbed up front a little but nothing major at all

wow, 5/7 on 22s, and it does not rub, man, thats a trip.   so now i just have to find the right rims.

it rubbed but it wasn't that bad
