Michelin Pilot Sport Cup 2 N2 – 325/30 ZR21 (108Y) XL TL is a track-focused ultra-high-performance summer tyre developed to meet Porsche original-equipment requirements for extreme dry grip, high-speed stability, and circuit-level performance. It utilises a motorsport-derived tread compound and a rigid asymmetric tread design optimised to deliver exceptional cornering force, braking stability, and precise steering response under extreme loads. The reduced tread void ratio maximises the dry contact patch, while longitudinal grooves provide limited wet-surface capability for road legality. Reinforced outer shoulder blocks and XL construction support very high axle loads and sustained high-G cornering. The Porsche N2 homologation confirms full compatibility with Porsche chassis dynamics, suspension tuning, and electronic stability systems.
