Hankook Tire has entered a new chapter in its longstanding partnership with Porsche by securing original equipment status for the iconic 911 Carrera. This marks the first time the South Korean manufacturer’s rubber will be mounted on the production line of the legendary rear-engine sports car, following nearly 10 years of supplying Porsche with tyres for other models. The bespoke fitment features a staggered setup, with 235/40 ZR19 tyres up front and wider 295/35 ZR20 tyres at the rear, both carrying a distinct ‘NA2’ sidewall designation that signifies their factory-approved specification.

The engineering effort behind this achievement was substantial, with Hankook’s specialists spending several years refining the product to satisfy Porsche’s exacting standards. The primary technical hurdle centred on harmonising contradictory performance demands – superb dry-road agility and lane-change precision versus reliable wet-weather traction. This balancing act proved especially delicate given the 911’s hallmark weight bias towards the back axle and its rear-wheel-drive configuration, which place unique stresses on tyre behaviour during aggressive cornering and acceleration.

To conquer these challenges, the development team crafted axle-specific tread patterns and geometries, each tailored to the distinct roles of front steering response and rear propulsion. A newly formulated compound was also introduced, incorporating advanced resins, silica and a specialised mixing technique to sustain peak grip across diverse road conditions. The material composition is engineered to maximise surface contact and reactivity, ensuring the tyre remains effective even on rain-slicked pavement where hydroplaning risks are heightened.

Validation of the new tyres involved an exceptionally rigorous testing schedule that stretched across multiple continents and facilities. Unlike conventional programmes that rely on a single location, Hankook deployed the 911 Carrera to Germany’s Papenburg track and Spain’s IDIADA circuit for handling assessments, while high-speed dry performance was scrutinised at Italy’s Nardò ring. Wet-weather tuning took place at Pferdsfeld in Germany and other test sites, with Porsche AG engineers working alongside Hankook’s team throughout the vehicle dynamics calibration process to ensure seamless integration.

Aleix Alcaraz, subjective test driver at Hankook, said, “Our goal was to deliver precise steering precision, stability at high speeds and reliable grip under all conditions. Striking a balance between track performance and everyday usability made this project particularly demanding. Pushing the 911 Carrera to its limits on test tracks like Nardò and applying the lessons learned to the road was both challenging and a special experience.”

Yong Chul Choi, Vice President and Head of the Hankook Europe Technical Center, said, “Becoming original equipment for the Porsche 911 Carrera – one of the world’s most renowned and iconic sports cars – is an extraordinary milestone for Hankook. This premiere is the result of many years of technical development work and reflects our continuously growing expertise in driving dynamics. It marks an important step for our commitment to the super sports car segment.”

DUNLOP (company name: Sumitomo Rubber Industries) has started equipping its GRANDTREK H/T31 and GRANDTREK H/T31T SUV tyres as original fitment on the LEXUS LX, following the flagship model's October model-year refresh. The supply arrangement extends the tyre maker's long-running association with Toyota's premium SUV lineup.

Engineered to complement the LX's dual character, the GRANDTREK tyre supports a vehicle that merges serious off-road ability with polished on-road manners. The updated LX brings revised tuning for greater ride comfort and handling poise, giving drivers reassurance across widely varying surfaces and conditions worldwide.

Two distinct grades shape the tyre fitment strategy. The OVERTRAIL+ variant moves to a larger 265/70R18 size from the previous 265/65R18, paired with added minimum ground clearance for tougher terrain. Meanwhile, the newly introduced F SPORT grade targets a sharper, more engaging driving experience, wrapped in styling that reads both muscular and elegant.

The GRANDTREK H/T31, specified for F SPORT, employs a highway-terrain pattern and fresh tread compound to balance low noise, fuel efficiency and wear resistance. DUNLOP's Nano Black sidewall treatment deepens the black finish of brand logos for greater visibility and a premium look. The H/T31T, reserved for OVERTRAIL+, strengthens on-road behaviour while delivering the comfort and load-bearing toughness the LX's heavy body demands, its exclusive sidewall design projecting rugged presence and refined off-road character.
