Nexen N FERA SUR4215/45ZR17
The N FERA SUR4 is Nexen’s competition-proven Extreme Performance Summer tire developed for serious sports car, sports coupe and performance sedan driving enthusiasts looking for race tire-like traction on the street or for tires for drifting, autocross and track events. Tuned for maximum performance in warm dry and damp conditions, the N FERA SUR4 is not intended to be serviced, stored, nor driven in near- and below-freezing temperatures, through snow or on ice.
Designed for competition, the N FERA SUR4 has been developed and refined through use in the Formula DRIFT racing series. A high-grip racing compound is molded into a directional tread design with a continuous center rib flanked by massive shoulders forming a highly rigid footprint that delivers high levels of dry grip and handling. The computer simulation-designed tread profile evenly distributes pressure and contact with the road, maximizing available traction for acceleration, braking, cornering and improving treadlife. Two wide, circumferential center grooves provide a direct path to channel water through the contact patch, while diagonal independent grooves help direct water to the sides of the footprint to enhance wet traction.
The N FERA SUR4 features a two-ply polyester casing to help resist lateral deflection and provide responsive handling and cornering stability. Two wide steel belts with a seamless, high-strength nylon cap ply (two-ply in 255 and wider section widths in 18- or 19-inch rim diameters) promote uniform ride quality and high-speed capability.
Note: Flexing of the specialized rubber compounds used in Extreme Performance Summer tires during cold-weather use can result in irreversible compound cracking. While 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.
