It delivers sharp handling, confident cornering, and strong braking in warm weather conditions. Drivers who demand a tire that keeps pace with their vehicle's power will find the SUR4G engineered precisely for that purpose — on dry and wet roads alike.\u003c\/p\u003e\n\u003cp\u003eThe SUR4G uses a symmetrical tread pattern featuring wide center ribs that promote high-speed stability and stiff diagonal blocks that sharpen handling through corners. Wide grooves channel water away from the contact patch efficiently, reducing hydroplaning risk on wet pavement. Because the compound is optimized for warm-weather grip, the tire should not be used or stored in temperatures below 50°F. Nexen backs it with a Total Coverage Warranty including 36 months of roadside assistance.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWide center ribs promote stability at elevated speeds\u003c\/li\u003e\n\u003cli\u003eStiff diagonal blocks sharpen cornering and handling response\u003c\/li\u003e\n\u003cli\u003eWide grooves evacuate water to reduce hydroplaning risk\u003c\/li\u003e\n\u003cli\u003eSymmetrical tread pattern designed for warm-weather performance\u003c\/li\u003e\n\u003cli\u003eNexen Total Coverage Warranty with 36 months of roadside assistance\u003c\/li\u003e\n\u003cli\u003eBlack sidewall finish suits performance and sports car aesthetics\u003c\/li\u003e\n\u003cli\u003eNot for use below 50°F — a dedicated warm-weather summer tire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerformance Profile\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeason Coverage:\u003c\/strong\u003e UHP Summer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjected Longevity:\u003c\/strong\u003e UTQG treadwear 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraction Grade:\u003c\/strong\u003e A (UTQG wet traction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Grade:\u003c\/strong\u003e A (UTQG heat resistance)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Nexen Tires\u003c\/h2\u003e\n\u003cp\u003eNexen Tire traces its origins to 1942, when the company was founded in South Korea under the name Heung-a Tire Industry. The brand adopted the Nexen name in 2000, drawing from the words \"Next\" and \"Century\" to reflect a forward-looking approach to tire development. With manufacturing operations in the United States and other regions, Nexen integrates global engineering practices and technologies across its product lineup.\u003c\/p\u003e\u003cp\u003eNexen offers a broad range of tire families to address diverse driving needs. The N'Blue lines are designed for all-weather versatility, while Roadian tires target rugged terrain and commercial applications. N'Fera tires are engineered for performance-oriented drivers, and N'Priz tires emphasize touring comfort. The N5000 and Aria lines focus on everyday commuting, and the Winguard series addresses winter conditions. In 2025, Nexen opened a dedicated winter tire testing center in Finland to further advance cold-weather performance development.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat does 275\/40R20102Y mean?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e275 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R20 is the 20-inch rim it mounts on. 102 is the load index (1,874 lbs per tire), and Y is the speed rating (up to 186 mph).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat kind of vehicles is the Nexen N'Fera SUR4G designed for?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe SUR4G is built specifically for sports cars and performance-oriented passenger vehicles. It pairs well with high-output powertrains where handling precision, braking response, and high-speed stability are priorities during warm-weather driving.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the N'Fera SUR4G handle wet roads?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes. The tire's wide grooves work alongside its tread design to push water away from the contact patch, lowering the risk of hydroplaning on wet pavement. That said, like all summer tires, it performs best when temperatures stay consistently above 50°F.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the N'Fera SUR4G safe to use in cold weather or snow?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. The SUR4G's compound is formulated for warm conditions and begins to harden as temperatures drop below 50°F, which reduces grip and can damage the tire over time. For cold climates or snowy conditions, a dedicated winter tire is the appropriate choice.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the N'Fera SUR4G a directional tire?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes, it uses a directional tread pattern, which means rotations are limited to front-to-rear and rear-to-front on the same side of the vehicle. Side-to-side swaps are not possible without dismounting and remounting the tires.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere are Nexen N'Fera SUR4G tires manufactured?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eN'Fera SUR4G tires may be produced at Nexen's facility in Richfield, Ohio, or at their manufacturing plant in South Korea, depending on the size and production run.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I get the full manufacturer warranty buying from TFS Wheels?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes.
