Architecture of the tire

The architecture or skeleton of the tire consists of the successive assembly of various components that may range from 20 to 50 in number, depending on the tire family: casing plies, ply for the crown belt, reinforcements for sidewalls and in tire attachment zones, etc. Its principal mission is to give the tire its shape and, once inflated, it will control its rigidity.
