Tiresoling Tire Repairs, 1920s

Shot of a pair of old, worn tires. Today, they would be scrapped. In the 1930s they repaired them. Graphics tell the story to start then we see numerous shots as a worker expands an old tyre on a pronged machine. He inspects tires for condition, some are rejected, but those that can be repaired, undergo a thorough round of buffing, cleaning and stippling before tread stock is added. Curing rings are added after and these are then clamped and heat treated with steam (vulcanised). Shots of various trucks driven around on tires that have undergone the Tiresoling treatment.
