    NEXEN N’Fera SUR4G, Extreme Ultra High Performance Summer Tire for Track & Street

    The Tire That Comes Standard on the Dodge Challenger 1320

    The NEXEN N’Fera SUR4G occupies the very top of NEXEN’s performance tire hierarchy. This is an extreme ultra high-performance summer tire, a category populated by tires engineered not for everyday comfort or longevity, but for one singular purpose: maximum grip. With perfect 10 out of 10 scores for both handling and braking, W and Y speed ratings, and a UTQG treadwear rating of 200 AA, the N’Fera SUR4G is built for the drivers who demand the absolute limit of what a street-legal tire can deliver.

    The SUR4G’s credentials are factory-validated at the highest level: it serves as original equipment on the Dodge Challenger 1320, a quarter-mile-focused performance machine whose launch performance depends entirely on the tire’s ability to grip and not let go. Real-world owners have confirmed the formula works. One Hellcat owner replaced a competing tire that delivered no traction with the SUR4G and described the transformation as finally being able to accelerate without feeling like he was on ice.

    Available in 21 sizes spanning 15-inch through 20-inch rim diameters, the N’Fera SUR4G covers a wide range of performance vehicle fitments, from classic sports coupes to modern American muscle, with wide configurations up to 275/40R20 available for the largest performance platforms.

    N’Fera SUR4G Performance Ratings

    The SUR4G’s rating profile is defined entirely by its performance priorities, perfect marks where it counts most, with honest trade-offs everywhere else.

    Handling, Rated 10/10

    A perfect 10 out of 10 for handling reflects the SUR4G’s advanced tread architecture: three wide center ribs that maximize vertical contact patch stiffness for high-speed straight-line stability, plus maximized diagonal block stiffness that enhances lateral grip and cornering precision. When turning in hard, the SUR4G stays planted and communicates exactly what the road surface is doing beneath the driver, a quality that separates genuinely elite performance tires from everything else.

    Braking, Rated 10/10

    A matching perfect braking score is delivered by the same center rib geometry that enhances handling. The three wide center ribs concentrate vertical stiffness directly under deceleration loads, allowing the compound to grip the road surface with maximum force as speed scrubs off, enabling later braking points on track and shorter emergency stops on the street.

    Wet Performance

    Two wide linear grooves and two diagonal grooves are integrated into the SUR4G’s tread design specifically to deliver high drainage performance and maintain grip on wet roads. This is a meaningful engineering commitment in a tire category where wet performance is often an afterthought. The groove architecture efficiently channels water away from the contact patch, providing confident wet-road capability that complements the tire’s dominant dry performance.

    Comfort, Rated 5/10

    A comfort score of 5 out of 10 is exactly what an extreme performance tire in this category should carry, and exactly what buyers should expect. The stiff sidewalls, shallow tread depths on select sizes, and ultra-soft compound that deliver perfect handling and braking scores inevitably transmit more road noise and vibration to the cabin. For track use, this feedback is informative and desirable. For highway commuting, it is a purposeful trade-off.

    Tread Life, Rated 4/10

    A tread score of 4 out of 10, backed by a UTQG treadwear rating of 200 on most sizes, and 100 on the flagship 275/40R20, is the clearest declaration of this tire’s priorities. The ultra-soft compound that makes the SUR4G one of the grippiest street-legal tires available wears faster than any standard street tire. Buyers should plan for replacement more frequently than with a touring or grand touring tire, and should treat this as the cost of operating at the performance level the SUR4G enables.

    Fuel Efficiency, Rated 5/10

    Fuel efficiency scores a 5 out of 10, the expected result of a maximum-traction compound with inherently higher rolling resistance. For its intended audience and use case, this is an irrelevant consideration.

    Speed Ratings, UTQG & Temperature Warning

    The N’Fera SUR4G is available in W speed rating (up to 168 mph) on 15-inch and 16-inch sizes, and Y speed rating (above 186 mph) across the 17-inch through 20-inch lineup, appropriate for the high-output vehicles this tire is designed to serve. Most sizes carry a UTQG of 200 AA, while the 275/40R20 carries a 100 AA rating, among the lowest UTQG treadwear designations available on a DOT street tire, reflecting an ultra-soft compound optimized for maximum launch grip.

    An important storage and use caution: the N’Fera SUR4G should never be stored or used below -10°C (14°F). The ultra-soft compound is not formulated for cold-weather operation, and sub-threshold temperatures can damage the tire and significantly impair performance. This tire is a dedicated warm-weather, summer-only performance tire and must be treated accordingly.

    N’Fera SUR4G Warranty, NEXEN Total Coverage

    As an extreme performance tire, the N’Fera SUR4G does not include a tread wear mileage warranty or road hazard warranty, standard for the category. It includes 36 months of roadside assistance through NEXEN’s Total Coverage Warranty.

    FAQs: Extreme Ultra High Performance Tire for Summer Driving

    What type of tire is the NEXEN N’Fera SUR4G?

    The NEXEN N’Fera SUR4G is an extreme ultra high performance (EUHP) summer tire. It is engineered for maximum grip on both the street and the track, earning a perfect 10 out of 10 scores for handling and braking. It is available in W and Y speed ratings across 21 sizes from 15-inch to 20-inch rim diameters, with UTQG ratings of 200 AA on most sizes and 100 AA on the 275/40R20.

    Is the N’Fera SUR4G an OEM tire?

    Yes. The N’Fera SUR4G is original equipment on the Dodge Challenger 1320, a quarter-mile performance variant of the Challenger lineup designed specifically for maximum launch traction. Its factory fitment on this vehicle validates its extreme grip and launch performance credentials at the highest level.

    What is the UTQG rating of the N’Fera SUR4G?

    Most N’Fera SUR4G sizes carry a UTQG rating of 200 A A, indicating a very soft, high-grip compound, strong traction, and good temperature resistance. The 275/40R20 size carries a 100 AA rating, one of the lowest treadwear designations available on a street-legal tire, reflecting an even softer compound formulated for maximum launch and acceleration grip.

    Can I use the N’Fera SUR4G in cold weather or winter?

    No. The N’Fera SUR4G must never be used or stored below -10°C (14°F). Its ultra-soft compound is not designed for cold-weather operation and can be permanently damaged by sub-threshold temperatures. It is a dedicated summer-only tire and must be replaced with an appropriate winter or all-season tire during cold months.

    What vehicles is the N’Fera SUR4G designed for?

    The N’Fera SUR4G is designed for high-output performance cars and American muscle vehicles that demand maximum grip. Its 21 sizes, ranging from 225/45R15 to 275/40R20, cover fitments for vehicles including the Dodge Challenger, Dodge Charger, Chevrolet Camaro, Ford Mustang, and similar performance platforms. Factory fitment on the Challenger 1320 is its most prominent OEM application.

    How does the N’Fera SUR4G compare to the N’Fera Sport R?

    Both tires are extreme high performance summer tires with identical 10/10 handling and braking scores and matching UTQG 200 AA ratings on most sizes. The key differences are in their size ranges and target applications. The N’Fera Sport R covers 15-inch through 19-inch in sizes oriented toward sports cars and European performance vehicles, while the SUR4G’s 21-size lineup extends to 20-inch with wider configurations, particularly the 275/40R20, making it a better fit for large-displacement American muscle platforms. The SUR4G also carries OEM validation from Dodge.

    Where can I buy the NEXEN N’Fera SUR4G?

    The N’Fera SUR4G is available through NEXEN’s authorized dealer network across the United States. Visit nexentireusa.com and use the Dealer Finder tool to locate the nearest retailer carrying the SUR4G in your vehicle’s fitment size.
