Nexen N'Fera SUR4G. FEATURES AND BENEFITS: Summer weather traction; Longer lasting tread life; Enhanced controllability; High speed durability; Vibration free drive; . OVERVIEW: The Nexen N'Fera SUR4G is an extreme performance summer tire manufactured for performance vehicles made for racing and street use.The tire has first-rate summer weather traction. It grips the road well in dry and wet weather thanks to the computer optimized tread pattern that maximizes the model's traction in such conditions. The special tread pattern features two circumferential grooves that improve the wet weather traction and promote excellent hydroplaning resistance with their water evacuating ability. The tire is not meant to be used in winter weather. The tire compound is not able to maintain traction and offer safety in colder weather. As a result, the tire only offers secure driving ability in summer conditions.The model's special computer optimized tread pattern upgrades the length of the tread life and the tire usability. The tread pattern's circuit adaption verified grooves, that look like four small lines on either side of the circumferential grooves, enable the tire to evenly distribute the driving pressure across the tread area. This equal spreading out of the forces of acceleration, cornering and braking avoids irregular wear patterns forming across the tread area. The prevention of uneven wear enables an increased usability and tread life, which makes the tire more cost-efficient.The tread pattern and the tire's internal structure allow an increased driving stability, steering responsiveness and cornering ability. Furthermore, it improves the tire's acceleration and braking ability, promoting a safer driving experience. The tread pattern's wing shaped grooves and special center rib stabilize the tire during the drive and enhance the steering response time and accuracy. The massive shoulder tread blocks ensure exceptional cornering and maneuvering ability with additional biting edges. The inner construction features a two-ply polyester casing that ensures constant road contact. The combination of these elements boosts the tire's summer weather controllability and handling.The Nexen N'Fera SUR4G features twin steel belts reinforced with spirally wrapped nylon cap ply in its internal structure. These maintain the optimal tire shape at all times and ensure a safer driving experience by doing so. The tire does not deform under the driving pressure affecting it, which enhances the high speed durability and the ride uniformity. The optimal tire shape allows the tire to perform to its utmost capability and it lowers the road vibrations felt in the vehicle's cabin, making the high speed drive more comfortable and safe. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
