Rolligon: The Tire that can Roll over Practically any ObstacleThis has got to be one of the weirdest tires ever made!Meet the "Rolligon," a large, low pressure tire invented by William Albee. In 1950, the California man went on a fishing trip to Alaska where he noticed an Inuit fisherman moved a heavy wooden boat up a muddy bank using what looked like balloons. It turned out that the rolling balloon was actually inflated seal skins.When he returned back home, Albee used a combination of fabric and rubber to create a low pressure tire that was perfect for use in the frozen tundra of Alaska.#tire #rolligon #Alaska #truck #balloon
