In Milan, Pirelli has been busy for the last four-and-a-half years developing a revolutionary tire, which is now in an advanced phase of development. It is of triangular section, has plain rubber sidewalls, can cover long distances in a completed deflated state without seriously impairing the car's maneuverability and directional stability and has driving characteristics similar to those of a conventional radial-ply tire. Its production requires less labor and machinery and it uses plain rubber walls devoid of any carcass. The principle of the new tire is that rubber has little resistance to deformation in tension but is very resistant in compression. Therefore, the sidewalls are made to work in compression rather than in tension, so that reinforcing cords are redundant. /HRIS/
