Find out when the Michelin tire was introduced.
The first pneumatic (air-filled) tire for automobiles was produced in France by André (1853-1931) and Edouard Michelin (1859-1940) in 1885. The first radial-ply tire, the Michelin X, was made and sold in 1948. In radial construction, layers of cord materials called plies are laid across the circumference of the tire from bead to bead (perpendicular to the direction of the tread centerline).
The plies can be made of steel wires or belts which circle the tire. Radial tires are said to give longer tread life, better handling, and a softer ride at medium and high speeds than bias or belted bias tires (both of which have plies laid diagonally). Radials give a firm, almost hard, ride at low speeds.
