With a 25,000-mile limited tread life warranty, it delivers genuine performance credentials at a competitive level — provided temperatures stay reliably above 45°F.\u003c\/p\u003e\n\u003cp\u003eThe N Fera SU1 uses a symmetrical tread pattern with three main grooves and one semi-groove that channel water out efficiently, reducing hydroplaning risk and supporting wet-road confidence. Split surface siping adds extra biting edges for grip on both dry and damp surfaces, while reinforced shoulder blocks distribute contact pressure evenly — sharpening cornering response and helping extend tread life.\u003c\/p\u003e\n\u003cp\u003eWe stock the Nexen N Fera SU1 in 4 sizes for 18\"–20\" wheels — every size below lists its exact specs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUltra-high-performance summer compound optimized for warm-weather traction\u003c\/li\u003e\n\u003cli\u003eThree main grooves plus a semi-groove reduce hydroplaning risk on wet roads\u003c\/li\u003e\n\u003cli\u003eSplit surface siping creates additional biting edges for dry and wet grip\u003c\/li\u003e\n\u003cli\u003eStiff shoulder blocks distribute pressure evenly for precise cornering control\u003c\/li\u003e\n\u003cli\u003e25,000-mile limited manufacturer tread life warranty included\u003c\/li\u003e\n\u003cli\u003eNexen Total Coverage: 2-year road hazard, 36-month roadside assistance, 45-day trial\u003c\/li\u003e\n\u003cli\u003eNot rated for snow or sustained temperatures below 45°F\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 300 · 25,000-mile manufacturer tread-life warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraction Grade:\u003c\/strong\u003e AA (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\u003eIs the Nexen N Fera SU1 a good tire for a performance sedan or coupe?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes — the N Fera SU1 is a solid fit for performance-oriented passenger cars driven primarily in warm weather. Its reinforced shoulder blocks sharpen cornering response while distributing road pressure evenly, and the grooved tread design handles wet conditions capably. Drivers who stay within its warm-weather operating range should find it a well-rounded UHP option.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the N Fera SU1 be used in snow or cold winter weather?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. The N Fera SU1 is a dedicated summer tire, and its rubber compound stiffens significantly when temperatures consistently drop below 45°F, reducing grip and safety. It should not be used in snow, ice, or cold-weather conditions. Drivers in climates with true winters should swap to a dedicated winter or all-weather tire for that season.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the N Fera SU1 perform in the rain?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tire handles wet roads reasonably well for a UHP summer tire. Three main grooves and one semi-groove work together to evacuate water from the contact patch, lowering hydroplaning risk, while split surface siping provides additional edges that bite into damp surfaces. It is not intended for standing-water extremes or cold rain near freezing temperatures.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long can I expect the N Fera SU1 to last?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNexen backs the N Fera SU1 with a 25,000-mile limited tread life warranty. Achieving that mileage depends on proper inflation, regular rotations, and alignment maintenance. The evenly loaded shoulder blocks also help spread wear across the tread, supporting longevity under normal performance driving conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Nexen N Fera SU1 a run-flat tire?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo, the N Fera SU1 does not have run-flat construction. In the event of a puncture or pressure loss, the tire will not support the vehicle's weight for extended driving. Nexen does include 36 months of roadside assistance through its Total Coverage Warranty, which can help in a roadside emergency.\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.

We program each sensor to your vehicle's exact year, make, model, and submodel before shipping, so they arrive ready to sync with your truck or car the moment they're installed.
