Pirelli Tyres The Beggining
Pirelli radial tyres were born from the need of Lancia rally, who wanted a stronger lower riding radial tyre for their “Lancia Stratos” rally car, this leads the designers to create a much more durable tyre construction, both wider and with a much lower side wall. This design became very successful and a great boost to “Lancia racing”, indeed Porsche also started to use the Pirelli Cinturato tyre in its racing division.
