well i've never owned a silverado before but to match your current offset with your 9.5" wide wheels you would need:
9" wide wheel = +19 offset/5.75" backspacing
9.5" wide wheel = +25 offset/6.25" backspacing
10" wide wheel = +32 offset/6.75" backspacing
so if your wheels are just barely rubbing, just get a bit more offset/backspacing than listed above.
