Pirelli Cinturato CN36 N Tire - 215/60 VR 15

Porsche equipped their RS and Carrera 911 models with the 185/70 VR15 Pirelli Cinturato CN36 tires on the front, while transitioning to broader rear wheels to fit the 215/60 VR15 Pirelli Cinturato CN36. Today, Pirelli is reproducing this tire with Porsche’s N homologation, signifying it has met Porsche's specific testing standards.

Notably, the 215/60 VR15 CN36 marked the debut of the 60 profile tire on production vehicles. Porsche persisted in using the 215/60 VR15 tires on the rears of their cars well into the 1980s.

The present-day version of this tire is often labeled as a 215/60 WR 15. While it now meets the criteria for a “W” speed rating (tested up to 168 mph / 270 km/h), such a rating wasn't accessible during its initial release. Historically, these tires bore a 215/60 VR15 mark on their sidewalls, as “WR” ratings were not in use at that time.
