This video reviews two new passenger tire launches from Nexen Tire, offering a detailed Nexen N’Priz S and N’Fera Sport review while also explaining how the company is using artificial intelligence in modern tire development. Nexen N'Priz S Review The Nexen N’Priz S is a grand touring all-season tire designed for modern vehicles, including electric vehicles, hybrids, and internal-combustion vehicles. Nexen identifies the N’Priz S as its first EV-compatible tire, engineered to manage higher vehicle weight, instant torque delivery, and reduced noise expectations common to electric vehicles. The tire features a wider contact patch compared to the previous generation, which helps distribute load more evenly for improved braking, stability, and wear. Nexen also incorporated variable-pitch shoulder blocks to reduce pattern noise. Plus, its 4D compound technology and 3D sipe design help maintain traction across temperature changes and light winter conditions.  The N’Priz S replaces the Roadian GTX, Aria AH7, and N’Priz AH8 in Nexen’s lineup.  It carries an 80,000-mile treadwear warranty for ICE vehicles and a 60,000-mile warranty for EV applications. Nexen N'Fera Sport Review The Nexen N’Fera Sport is a premium ultra-high-performance summer tire developed to meet European OE performance expectations. Nexen focused on high-speed stability, wet braking, and steering precision by using a stiffer shoulder design, a reinforced center block, and a new tread compound with increased silica content and updated polymer chemistry. The tire uses a four-channel longitudinal groove design to evacuate water efficiently at speed. Elements such as a jointless bead wire, high-hardness bead filler, and high-tensile steel belt help maintain stability under load.  The N’Fera Sport is offered in 63 sizes and includes a 30,000-mile treadwear warranty. The tire has also received a Red Dot Design Award. How is Nexen Tire Using AI? Beyond the product reviews, the video explains how Nexen Tire is applying artificial intelligence and machine learning in tire development. Nexen engineers describe AI as a tool that analyzes large datasets from tire specifications, compounds, construction variables, simulations, and testing. Nexen maintains a global database with data from approximately 190,000 tire designs. This database allows proprietary AI systems to predict outcomes, evaluate design changes, and help engineers reach targets faster. Aaron Neumann, head of Nexen’s America’s Technical Center, explains that AI does not replace engineers. It does not make independent design decisions. Instead, AI supports development by accelerating analysis and improving early-stage decision-making. This Nexen N’Priz S and N’Fera Sport review provides dealers, industry professionals, and performance-focused drivers a detailed look at Nexen’s latest all-season and UHP tire technology with Nexen N’Priz S and N’Fera Sport review. It also explains how AI influences tire design, testing, and future product development at Nexen Tire.

Today, we take you inside Hunter Engineering’s St. Louis headquarters for an in-depth look at the Hunter HawkEye Elite X, the company’s latest expandable alignment system designed to future-proof shops as ADAS work becomes unavoidable. Hunter’s Wheel Alignment Product Engineer, Alan Hagerty, joins Tire Review’s David Sickels to break down what the “X” really means for tire dealers: more storage, more capability, and a built-in upgrade path that lets a shop buy top-tier alignment technology today and add static ADAS calibration when they’re ready. Alan walks through how the system retains Hunter’s quick-grip, time-tested alignment tech while bringing new flexibility to the bay. The Elite X ships with Hunter’s ADASLink scan tool, allowing shops to perform mechanical alignments, steering resets, and dynamic ADAS calibrations without changing bays. That combination gives dealers a way to handle the majority of forward-facing calibration needs while building confidence before stepping into full static calibration setups. For shops worried about space, Alan explains why most dealers start with dynamic calibrations and how the mobile, wheeled design of the Elite X helps them reconfigure the bay as needed – even rolling the unit aside for static calibrations when the time comes. Alan also outlines who the system serves. He explains the ROI considerations behind adding ADAS capability. He shows how Hunter’s team supports the upgrade process from start to finish. Whether you’re already doing high volumes of alignments or evaluating ADAS as a new revenue stream, this episode breaks down how the Hunter HawkEye Elite X helps tire dealers grow by easily adding ADAS calibration to an existing alignment system.

Shops want faster workflows, fewer bottlenecks, and equipment that keeps technicians moving. On this episode of What's Treading, we set out to learn how well the new Road Force WalkAway tire balancer supports those goals during a visit to Hunter Engineering’s headquarters. We wanted to see how much time a modern balancer can actually save and what that means for daily productivity inside a busy tire bay. Hunter’s David Henry kicked things off by showing the biggest change: automatic inflation built directly into the balancer. Technicians can clamp the wheel, hook on the hose, and drop the hood, and the machine handles the rest. Henry explained that this feature frees up 45 to 90 seconds, which technicians can use to mount the next tire, prep weights, grab a tire from the rack, or keep another bay moving. The WalkAway still performs full Road Force diagnostics, measures spring rate, identifies stiff spots, and uses camera-based wheel measurement. But the team redesigned the hood and roller assembly to shrink the footprint by 4.5 inches to reclaim some space. Engineering Manager Nate Brower explained how the machine calculates time savings through pressure readings, volume calculations, and flow rate. It gives technicians a countdown that shows how long they have to complete other tasks. In testing, he said, pairing the Road Force WalkAway with Hunter’s automated tire changers cut a four-tire job from 34 minutes to 19, which delivered a 44% time savings. The WalkAway also integrates with HunterNet, which lets multi-store operations track usage, roller drops, inflation habits, and technician performance.

A growing number of vehicles on the road still lack tire pressure monitoring systems, and Schrader is hoping to change that with its new Aircheck BLE retrofit kit. In this episode of What’s Treading, David Sickels talks with Kelly Sadler, vice president and general manager for Sonata’s aftermarket business, about how the product works and what it means for both drivers and service shops. The Aircheck BLE is designed to fit nearly any light-duty vehicle and deliver tire pressure, temperature, and sensor battery life information directly to the dashboard through Android Auto or Apple CarPlay. Sadler explains that the system uses Bluetooth Low Energy and a range extender to ensure reliable communication even over long distances, such as when towing a trailer. For installers, Schrader kept setup simple. The sensors mount internally to protect against tampering and provide more accurate readings, while an app-based configuration removes the need for hard-wiring and specialized tools. Sadler says installation typically takes less than five minutes and that the company has produced full training materials and videos to help technicians get up to speed. With roughly 250 million vehicles still operating without TPMS, the retrofit market represents a sizable opportunity for tire dealers looking to expand their services. Sadler notes that the Aircheck BLE’s single-SKU design helps streamline inventory and reduce complexity in the bay, giving shops a way to add value for customers who want better tire health monitoring without replacing their vehicle.

Three tires, one incredible day at the track. At the scenic Burt Brothers Motorpark in Salt Lake City, we spent the day doing a good, old-fashioned Sailun tire test, putting three of Sailun Tire Americas’ newest products – the Atrezzo SVA2 ultra-high-performance all-season tire, the Terramax AT2 all-terrain tire, and Terramax RT rugged-terrain tire – through their paces across asphalt, gravel, and rock, respectively. Each tire showed off its unique performance and character. We started with the Atrezzo SVA2, developed by the Chattanooga-based R&D team for North American roads. It features an asymmetrical tread design and Quiet Ride Technology for confident handling and a calm, composed feel. Next up was the Terramax AT2, designed for drivers who divide their time between the highway and off-road. The AT2 features a new casing, enhanced compound, and protective sidewall biters for traction and cut resistance. It’s 3-Peak Mountain Snowflake certified and backed by a 50,000-mile warranty. We wrapped up this Sailun tire test with the Terramax RT, the company’s first rugged-terrain tire. Positioned between an A/T and M/T, it provides aggressive grip without the excessive noise or harshness often found in mud-terrains. Its squared profile and staggered shoulder lugs with stone ejectors are designed to give it confident traction and a stable, on-road feel. Which of these three would perform best in your market? Let us know, and stay tuned for more from What’s Treading.

Cosmo Tires wanted to prove its newest extreme all-terrain tire, the Gripit XT, in a place that could push it to its limits. That’s how I ended up in Peru (home to one of the driest deserts in the world) with about 100 dealers, distributors, and Cosmo Tires team members. If you want to see what a tire can do on dunes as tall as mountains, there aren’t many better options. Loose sand and steep slopes are some of the toughest conditions for any tire to thrive in. If the Gripit XT could climb the dunes of Ica, it could likely handle just about anywhere drivers might take it. “There is no substitute for having hands-on experience,” CEO Tony Gonzalez said. “The tire performs beyond expectation… and you can see them doing their job right here in the middle of the desert.” Tires like the Gripit XT are personal for Tony. He literally hand-drew its tread pattern before working with engineers to turn that sketch into reality. Out on the sand, the scalloped shoulder lugs dug deep for traction, while Bead Claw reinforcements kept the tire locked on the rim. Cosmo’s Quiet Kat technology (using geometric isolation grooves to break up airflow) kept road noise low. Many sizes feature a 3-ply sidewall and up to 12 plies of under-tread reinforcement for heat control, puncture resistance, and stability. The tire also features Cosmo’s Directed Super Silica compound for cut resistance, wet grip, and lower rolling resistance. Cosmo also backs the tire with a 50,000-mile warranty and its Hassle-Free Warranty Suite. Tire Review: www.tirereview.com Hunter Engineering: www.hunter.com

Today's the day that we put drive tire ROI front and center. On this episode of What's Treading, Valentino Faraone, Regional Vice President & New Product Development Manager at Double Coin, explains why fleets and dealers should give more attention to this tire position to boost the bottom line. Valentino notes that while steer and trailer tires often dominate purchasing decisions, drive tires carry a heavy cost. They also play a major role in a fleet’s total cost of ownership. He shares methods for calculating drive tire ROI, tracking mileage, and comparing acquisition costs. He also suggests using simple spreadsheets to benchmark performance against other products. The conversation highlights the importance of preventative maintenance. Dealers can deliver real value by monitoring tread depth, air pressure, and mismatched diameters before costly breakdowns occur. Valentino explains that this proactive approach may require an upfront investment but provides significant long-term savings and peace of mind. He also discusses Double Coin’s durability approach, building heavier, more robust tires that excel in harsh environments and offer strong retreadability. That combination, he says, helps fleets maximize value throughout the tire’s lifecycle. For commercial fleets, product quality matters as much as service and maintenance. Dealers who prioritize reliability, preventative maintenance, and consistent support build lasting trust with fleets and owner-operators, Valentino says. Watch now for Valentino’s insights on service, durability, and why the drive tire should never be overlooked in a fleet’s ROI strategy.

When you look at a tire, the tread pattern seems like a given... but that wasn’t always the case. Over a century ago, tires were just smooth rubber. That changed in the early 1900s when Continental unveiled the first-ever hand-carved tread pattern at the Frankfurt Auto Show, a move that transformed how tires deliver traction, braking, and steering. To mark 120 years since that invention, we sat down with Barry Terzaken, Product Manager at Continental, to explore how tread design has evolved and where it’s headed next. From Hand-Carved Grooves to Specialized Patterns The first tread was simple: circumferential grooves cut into the tire to help it steer and grip on wet or muddy roads. Terzaken explained that Continental hand-carved early designs to experiment with performance, a practice they still use today alongside advanced simulation and AI modeling. “[Adding tread] was really an astounding change. You have to go back a little bit farther because you're talking about the dawn of private mobility in vehicles at this time,” said Terzaken. “There were needs for traction, there was needs for braking and steering ability. And at the Frankfurt Auto Show, this is the first introduction of an actual hand carved tread pattern. This is where Continental came in.” Modern Continental Tread Pattern Designs Built for Every Driver Today, tread design is highly specialized. Ultra-high-performance summer tires feature asymmetric patterns for cornering grip. Winter and wet-weather tires use directional V-shaped grooves to channel water and snow. Every day, passenger tires often use symmetric patterns to allow easy rotation. Terzaken highlighted how much engineering goes into every detail, even the small ones. "If you look at a lot of our all-season tire grooves, they have little teeth called traction grooves," he explained. "With those little teeth inside that groove, now all of a sudden the groove is giving you traction in a condition where you really need traction, for example."  120 Years, and Still Carving the Future What started as a hand-carved experiment in 1904 is now a field driven by AI, simulation, and thousands of patents. But as Terzaken reminded us, it’s still about one thing: giving drivers the grip, control, and confidence they need on the road. Check out the full episode to see how Continental is celebrating 120 years of tread pattern innovation and pushing the limits of tire design for the next century.

EVs aren’t just sedans anymore — they’re trucks. And those trucks need tires built for weight, torque, and traction. That’s where the new EV truck tire, the Hankook iON HT, comes in. We met up with Robert Nasca, Product & Marketing Training Manager at Hankook Tire, at the Electrify Expo in LA, where Hankook revealed the latest addition to their EV-specific iON lineup. Built from the ground up for electric vehicles, the iON HT targets electric light trucks and SUVs — a segment Nasca says had been missing a purpose-built EV tire. Hankook iON HT Tire: Tailored for Performance According to Nasca, an EV truck can weigh up to 30% more than its gas-powered equivalent. That means more torque, more braking force — and a lot more stress on the tire. Hankook addressed that with: An “XL” load designation for extra strength;Reinforced sidewalls for added rigidity;A construction that handles electric torque and heavy loads.Nasca highlighted Hankook’s use of Roll Lite Compound and Opti Cure Technology to reduce rolling resistance and improve range. The tire also includes ProDurable Compound and Opti Tread Technology, which support an industry-leading 80,000-mile treadwear warranty. Striking Design and Smart Serviceability One standout feature? The iON Clad sidewall, which draws inspiration from lightning. And in a move that prioritizes ease of service, Hankook left out inner foam — a decision based on feedback from OEMs and retailers who say foam-lined tires can be difficult to service. This EV Truck Tire Arrives in August Made in Korea, the iON HT arrives this August in 18- to 22-inch sizes with T and H speed ratings. For shops and drivers looking to support electric trucks with the right tire, this new EV truck tire stands ready. Watch the full video to see our conversation with Robert Nasca and get a closer look at the iON HT in action at the Electrify Expo.
