I think the red tire problem with your build is the subtle difference in the shade of orange. The orange soda is vibrant enough that the tires and tape work. There is no hard science in this, that is why it falls under Art Theory. Honestly I would have never done it in a million years, then I saw red Hetres on Jenny Oh’s Rambler and was swayed. That said I still want green tires before 2015 is out
