Falken 28038585 Azenis FK510 255/40ZR18 99Y XL Ultra High Performance Summer Tire

The Falken Azenis FK510 is an ultra-high-performance summer tire engineered for drivers of premium sports and luxury vehicles who demand outstanding grip, precise handling, and confident stability in both dry and wet conditions. Available in a 255/40ZR18 size with an XL load rating, this tire is built to meet the performance demands of high-powered passenger cars.

Key Features:

• 4D Nano Design Technology: Falken's proprietary compound optimization at the molecular level enhances wet-weather traction while fighting off uneven wear for longer tread life.
• Hybrid Undertread Cap Ply: A combination of aramid and nylon materials delivers added rigidity and high-speed stability while maintaining controlled flexibility for a responsive, comfortable ride.
• Tension Control Technology: A proprietary casing mold shape creates a more flexible middle sidewall that absorbs road shock, while the rigid outer shoulder tread and bead area enhance handling and help reduce road noise and vibrations.
• Wide Shoulder Blocks: Put more rubber in contact with the road surface, improving high-speed cornering performance and directional stability.
• Variable Sipe Depth & Optimized Void Ratio: Maintains overall block rigidity while allowing controlled tread flexibility, contributing to shorter braking distances and improved handling.
• Four Wide Circumferential Grooves: Efficiently evacuate water from the contact patch to reduce hydroplaning risk and maintain strong wet-road traction.
• XL (Extra Load) Rated: Engineered to support the increased mass and power of today's performance-oriented vehicles.
