The Double Rivet, Michelin's first wired-on crossply tyre design, arrived in 1925. It shares the name with the beaded-edge tyres it replaced but not the high inflation pressures and reliability issues. There are 14 sizes in the Double Rivet range. This 475/525-18 fits cars including the Riley 12, MPH, Alpine Six, Rover 12, Standard 12, Wolseley Hornet (1930s), Aston Martin Le Mans and Bugatti Type 49.
