18-19 intro wheels on a Chevelle?

[Gordz32]

Hey guys, I found a deal on an 18-19 combo for the chevelle. The wheels are intro pentia's. First off does anyone know where I can find a pic of a chevelle with an 18-19 combo or a chevelle with the pentia wheels on it. Next what tires sizes to run. Rears are 19x10 with 5.5" backspacing and fronts are 18x8 with 4.5 backspace. Can I get away with a 315-35-19 on the rear and a 275-40-18 on the front. or will I have to go slimmer. Tell me what you guys think and info is always appreciated.
