4.30 W/28" Rubber or 3.90 on 26" Shoes?

Short tires on the back of any a body visas don't look right to me. I've got 255-60-14 hoosiers and from most angles that big back window/slab sided area over powers the tires. That why I feel that the 68 SS b' cudas looked as good as any muscle car with those tall tires .
