At the end of the 60’s, after many years of study and experimentation, a new technological era started: the use of the steel belt on high performance tyres of HR and VR series (for speeds up to 210 km/h and more). In 1968 the CINTURATO CN36™ was born, specifically created for the Fiat Dino sized 185 HR 14. Designed to match the performance of High Performance and “Gran Turismo” cars, it was the first Pirelli steel radial tyre of standard production. It also marked the Pirelli re-entry into competitions (Rallies) and registered countless victories. The pattern stated as “soft at low speed and precise at high speed”, with longitudinal and diagonal elements that permitted the absorption of obstacles and above all kept the aquaplaning effect at bay. It was a HR tyre with notable sport features, which after a few years extended its size range to both the Serie 70 intended to equip BMW models and the 13 inch sizes with which the Fiat 124 Sport was equipped in 1971. It was thanks to the 124 Sport/ CN36 combination that Pirelli’s long history at the top of International Rally began.
