wheel and tire combo fit ok on my 67 r/t?

thinking im gonna get some of the newer US Mags torq thrust looking wheels.
just want to double check tire size for clearance.

for the front i was thinking 15x7 wheel with 3.75" back space with a 215-65-15 tire

for the rear a 15x8 wheel with 4.5" back space and a 245-60-15 tire

here is a pic with the 215/70/14

btw does my car look lowered a little? i kinda think it is in the front just a bit

stock backspace will work for those tire sizes and a 7 inch wheel is enough for a 245 by 15 if less expensive

thanks, i havent had a wheel off to measure the stock back space. the 7" wheel is only available in 1 backspace and the 8" are available in 2 backspaces. either about 75% of the extra width mostly on the inside or mostly on the outside
