Tires: Urethane v. Silicone
Tires: Urethane v. Silicone. The avoidance of tread separation, which can lead to severe accidents, is an added benefit of urethane’s one-piece tire composition—a traditional tire can often suffer blow-outs along treads. Although urethane tires can run without air, tires used on trucks and cars operate best with about 5 pounds of air per square inch.

Asphalt rubber pavement moves east and north | Asphalt
It is important to distinguish between asphalt rubber and rubberized asphalt, which are very different in composition and performance. AR is defined by ASTM as a blend of hot paving grade asphalt cement, reclaimed tire rubber and additives, in which the rubber content is at least 15 percent by weight of the liquid asphalt binder and has reacted sufficiently to cause swelling of the rubber particles.

The International Natural Rubber Market, 1870-1930 - EH.net
Overview of the Rubber Market, 1870-1930. In 1839 Charles Goodyear improved the process called vulcanization, which modified rubber so that it would support extreme temperatures. It was then that natural rubber became suitable for producing hoses, tires, industrial bands, sheets, shoes, shoe soles, and other products.

Natural rubber
South America remained the main source of latex rubber used during much of the 19th century. The rubber trade was heavily controlled by business interests but no laws expressly prohibited the export of seeds or plants. In 1876, Henry Wickham smuggled 70,000 Amazonian rubber tree seeds from Brazil and delivered them to Kew Gardens, England. Only 2,400 of these germinated.
