The modern pre-cured retread process was invented to keep Rommel’s army moving in the desert sands of North Africa during World War II. The heat of the sand was ideal for low temperature incubation of an adhesive.
Technical Notebook: The story of retreading – Making sustainability sustainable
After the war, a more advanced version of the technology became the primary method for recycling tires. With the advent of the radial tire and its improved durability versus bias, along with the scarcity of replacement radial tires, retreading expanded throughout the world in the 1970s, from passenger to commercial truck and bus.
Although passenger tire retreading fell out of economic favor, commercial vehicles still use retreads in large percentages. One estimate shows half of all commercial tire positions today are retreads. Considering each retread saves an estimated 60 liters of oil per tire and keeps a spent casing out of landfill, retreading is a perfect example of how to make sustainability sustainable.
