My 65 Dart Go Go had a set of green stripe tires on it when I got it in 1966. There were some places doing custom stripes, and I think you could get a yellow and maybe a blue, all thin like the red lines. I don’t know how they did it, but it looked factory. I wish I could find out if anyone does it now. The green I had was a lime green and it looked cool with the stock yellow paint.
