Hi Dick and list, Michelin invented the radial tire in 1946 (patent: 06/04/1946). The first radial was named "pneu X" in 1949. In 1952, Michelin extended the radial to truck tires. I remember that, before 1960, french cars were factory sold with radials (but not economic cars like 2CV , Dauphine or Simca 1000..). But french people waited until 1970 to have power windows in a regular car (except luxury low production Facel) -- Philippe COURANT (Pau, France)- Webmaster des sites ACCF et C-I-F Imperial 1957 Crown convertible Buick 1958 Roadmaster sedan HT - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France (C-I-F) : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar
