im looking at getting a 7-9"lift by either cognito or cst...i was looking at these rims is this size way off for this lift
20 X 8.5" 6 ON 5.5" +10MM OFFSET 78mm
would these even fit..i dont know much about the offset and whole rim size stuff.

Those won't fit an HD 8-lug. I am pretty sure the "6 on 5.5" part refers to the lug set up on the wheels and that means they would fit a 6 lug wheel with a 5.5" diameter lug measurement. The HD GM's require an 8x6.5" I believe. Tommy
