The ADVAN Apex V601 is Yokohama's Max Performance Summer tire for drivers of sports cars, performance sedans, and sporty coupes who want a tire that builds on the lessons learned from five decades of performance innovation. The ADVAN Apex V601 is designed to deliver maximum grip and precision handling in warm dry and wet conditions, so like all Max Performance Summer tires, it is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.A high-grade, micro silica tread compound is molded into the ADVAN Apex V601's asymmetric pattern. Optimized groove angles are designed to minimize noise for a quieter ride, and the rounded rib profile promotes even contact pressure with the road to reduce uneven tread wear. The wide, outboard rib features very low void for maximum lateral grip, and the solid center rib creates constant contact with the road for high-speed stability and precise handling. The narrow, outer groove helps dissipate the heat generated under aggressive cornering, and the three inside circumferential grooves effectively evacuate water from the contact patch to resist hydroplaning.The single-ply, rayon casing of the ADVAN Apex V601 features a high turn-up, creating a two-ply sidewall for enhanced lateral stability and handling. Two wide, steel belts support the tread and are reinforced with two spirally wound, nylon cap plies.Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage. Tires exhibiting compound cracking must be replaced.
