Before Charles Goodyear risked total ruin and debtor’s prison to master sticky tree sap, rubber was an unpredictable nightmare—melting in the summer heat and shattering like glass in the winter cold. Discover how an accidental spill on a hot stove, a bicycle ride over rough cobblestones, and brutal colonial monopolies turned raw latex into the pneumatic rubber tires that drive the modern world.

Full Episode Description We roll over thousands of miles of black asphalt every single year without a second thought, but the journey to create the modern rubber tire was paved with obsessions, tragic bankruptcies, and global competition. In the fifth episode of Everyday Things Untold Stories, host Jonathan explores the wild, high-stakes history of vulcanized rubber and pneumatic wheels.

What You’ll Discover in Episode 5:

• Goodyear’s Deadly Obsession: How Charles Goodyear spent decades in extreme poverty, selling his children's schoolbooks and experimenting in prison cells before accidentally discovering vulcanization.
• Dunlop’s Tricycle Revolution: How Scottish veterinarian John Boyd Dunlop invented the air-filled pneumatic tire in 1888 simply to give his young son a smoother ride over rough cobblestones.
• The Michelin Detour: How French brothers Édouard and André Michelin turned air-filled tires into easily replaceable bicycle and automobile components—and launched a famous travel guide in the process.
• The Dark Side of Rubber: The grim geopolitics and intense industrial race that made rubber one of the most coveted and contested resources of the modern industrial era.
