Help with some sizes
I like my wheel openings to just cover the tops of my tires. This is a personal thing. I agree that you don't want to end up with a big gap between the top of the tire and the wheel well lip.
You have 2 ways to go here........
Taller than stock tire
or....... and what I do..............
Stock tire height and adjust the (body) ride height to get the look.
For me it was flip the front, rear spring hangers and adjust down the torsion bars.
