New 15" rear tires

No rubbing. 1" inside clearance. 1 1/4" outside. I would like to try a custom offset 8" wheel just for fun. Yes I have the 5 leaf springs. The car was born with the HD option and the 6 leaf springs but I goofed when I ordered them years ago. My rallys ar 15x7 with a 4" back space
