Illuminated tires developed by Goodyear but were never mass produced, 1961.⠀
In 1961, Goodyear Tires introduced an experimental tire that was illuminated from the inside. Small incandescent bulbs were mounted inside the tire through holes inside the rim and the actual tire was made from a single piece of synthetic rubber. The synthetic rubber was created much thinner than a regular tire to allow for the light to penetrate the thick rubber. Unfortunately, due to the strict laws regarding the manufacturing of street-legal tires and the obvious hazard of having fragile glass inside them, Goodyear’s illuminated tires never actually saw mass production. Their flashy tires were regulated to being a novelty at several car shows throughout the early 60s.
