[7notry8]

I have a 1967 Chevy C10 step-side that is lowered 6 in the front and 7 in the back. The rim I would like to run is a 20x9 with a 6 inch backspace and a +25 offset. My question is do I have enough clearance to run these rims? And what kind of tire size would I be looking at getting? Thank you for the help.
