Falken Azenis FK453 Radial Tire - 215/40R18 89Z XL Flagship summer ultra high performance Silica-enriched compound: designed and tested to meet the demands of European roads, the silica-based compound provides superior traction and grip in wet and dry conditions. Asymmetric variable tread design with large outside shoulder blocks provide enhanced wet and dry handling while reducing tire noise. Rigid carcass retains the tire profile during some of the most extreme driving conditions, helping to enhance high-speed stability and handling. Three wide circumferential grooves effectively evacuate water and significantly enhance hydroplaning resistance for enhanced wet handling.
