Hab ich vorher noch nie von gehört und bin um so überraschter, dass die Dinger in Kanada und Alaska so wohl noch gefahren werden.
Rolligon is a trademark name for large, low-pressure tires, designed to traverse the soft ground surfaces of the tundra. The product was invented by William Albee in 1951 after he had seen Inuit using inflated seal hides to drag a heavy boat on shore. Because the weight of the vehicle is spread over a much larger surface compared to conventional tires, the pressure is much lower. This prevents the vehicle from getting stuck, and limits damage to vulnerable plants of the tundra.
