Nexen 13418NXK N'Fera SU1 245/45ZR17 99Y XL Ultra High Performance Summer Tire

The Nexen N'Fera SU1 is an ultra-high-performance asymmetric summer tire engineered for drivers who demand maximum grip on both dry roads and in wet-weather conditions. Designed for performance-oriented coupes and sedans, the SU1 delivers exceptional traction, confident high-speed cornering, and responsive handling — all backed by a 25,000-mile tread life warranty.

Key Features:

• 3 Main Grooves + 1 Semi-Groove: Work together to rapidly channel water away from the contact patch, reducing hydroplaning risk and enhancing wet-road stability
• Optimum Split Surface Siping: Creates additional biting edges across tread blocks for superior grip on both wet and dry surfaces
• Stiffened Shoulder Blocks: Evenly distribute road pressure across the contact patch for maximum cornering performance and extended tread life
• Asymmetric Tread Design: Optimizes the tire's inner and outer zones independently for a balance of wet handling and dry grip
• Extra Load (XL) Construction: 4-ply rated for higher load capacity at elevated inflation pressures
