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 525/600-19 fits cars including the Alvis Speed 20, Alfa Romeo 17/90 GT and Delage D5.
