The standard tyre fitted to the C1 was a 820x120 beaded-edge type, with some later cars fitted with a larger 895x135.
The C1 was the first of Voisin's line of amazing cars produced when aircraft production halted at the end of the Great War. Sleeve-vale engines and both luxury and high-performance in an adaptable package, it was sold as a limousine and a Grands Prix car!
