Budd–Michelin rubber-tired rail cars Budd–Michelin rubber-tired rail cars The Budd–Michelin rubber-tired rail cars were built by the Budd Company in the United States between 1931 and 1933 using French firm Michelin's "Micheline" rail car design. Michelin built its first rail car in 1929, and by 1932 had built a fleet of nine cars that all featured innovative and distinctive pneumatic tires. In September 1931, an agreement signed between the two companies allowed Budd to use the new rubber rail tires on its shot-welded, stainless-steel carbodies, and at the same time allowed Michelin to expand into the American market.

Crumb rubber to styrene-butadiene (SBR) granulate infills in artificial turf could potentially occur.” Scientific Instrument Services, Volatile Organic Emissions from Automobile Tires, 1999, Santford V. Overton & John J. Manura : Tire "Brand A were found to contain numerous straight and branched chain hydrocarbons, aldehydes, alcohols, ketones, furans and benzene derivatives." Tire brand B was..."found to contain high concentrations of the compounds sulfur dioxide (DOT), 2-methyl-1-propene, 2-propanone, 2-methyl-2-pentene, 2,4-pentanedione, acetic acid and 2,4-(1H, 3H) pyrimidinedione." Chemicals extracted from raw tires in this study would be found in crumb rubber, which is made by grinding feedstock tires. The chemicals listed above include carcinogens,
