The Kinforest KF550 255/30ZR19 91Y XL is a reinforced ultra high-performance tyre engineered for performance-oriented passenger vehicles requiring maximum steering precision and high-speed stability.

The 30-series ultra-low-profile construction significantly reduces sidewall flex, enhancing lateral rigidity and cornering response. The 255 mm footprint increases road contact area, improving braking performance and high-speed directional control.

The 91 load index (615 kg) combined with XL reinforcement supports higher dynamic loads associated with sport driving. The Y-speed rating (300 km/h) confirms structural capability for sustained high-speed operation under controlled conditions.

The asymmetric tread design optimizes dry grip while maintaining wet safety through wide circumferential drainage channels.
