Diamond Back does not make tires. They take name brand black wall tires and customize them for you. You are still limited to what is available in specific sizes: as we know not all brands come in all sizes and they deal with many major brands. They actually use a vinyl product and the black rubber can not bleed thru like the old white walls did so the ‘white’ stays white. They also offer red line, gold line, blue line etc. I have the wide whites with baby moons on my 63 long box Chevy and they look as good as they day we got them; very easy to maintain.
