There were only two sets of these tires released to the public. An original set to the creator of this car and this set, that Goodyear gave to the place that restored this car.
The neothane is clear and the originals had 18 lightbulbs installed inside to get the glowing effect.
The never made it to production despite Goodyear spending 10 years trying to make it happen. Mostly because they were very expensive, and not at all practical – the tires would get dirty and the effect would be loss. Also, neothane didn’t provide enough grip in the rain nor did it stand up under hard breaking, as it had a low pour temp of about 250F
