I don’t think you have enough backspace on those Cragars. I have run both stock 15x7 GM steel rims (about 4 1/4 backspace) and Rally 2 rims(4 3/8 backspace) with 215/65/15 tires and I have no problems. You might be able to get away with your tire size if more backspace pulls the tires in a little more
