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.

Butyl rubber rubbers such as natural rubber and styrene-butadiene rubber. Halobutyl is today the most important material for the inner linings of tubeless tires. Francis P. Baldwin received the 1979 Charles Goodyear Medal for the many patents he held for these developments. In the spring of 2013 two incidents of PIB contamination in the English Channel, believed to be connected, were described as the worst UK marine pollution 'for decades'. The RSPB estimated over 2,600 seabirds were killed by the chemical and hundreds more were rescued and decontaminated. Polyisobutylene can be reacted with maleic anhydride to make polyisobutenylsuccinic anhydride (PIBSA), which can
