Michelin develops bespoke rubber for new Porsche 911 GT3

0

Eight out of 10 new Porsche 911 GT3s will roll off the production line fitted with specially-developed Michelin Pilot Sport Cup 2 N1 ultra-high-performance tires in sizes 245/35 Z R20 at the front and 305/30 Z R20 at the rear.

Compared with its N0 marked predecessor, the new road legal track tire is said to provide very high grip levels, consistent performance and excellent front/rear balance, while still conforming to European regulations concerning rolling resistance (R117-2).

The co-development of these tires took two and a half years, in which time around 350 prototypes were made. Intensive track testing took place at Michelin’s Ladoux test center in France, and the Nürburgring and Nardo tracks in Germany and Italy respectively.

An innovative range of motorsport-derived technologies are used in the tires, including multi-compound technology where different rubber compounds are used on the inner and outer sections of the tread to ensure high and consistent grip levels in a variety of weather conditions.

In addition, track variable contact patch 3.0 optimizes the pressure in the tire’s contact patch so the same amount of rubber is always in contact with the road or track, whether driving in a straight line or cornering.
