A global tyre manufacturer NEXEN TIRE is revolutionising tyre development by integrating advanced technologies such as eXplainable AI (XAI) and 3D printing.

NEXEN TIRE has traditionally followed a multi-step process for tyre development, involving designing structures and patterns, creating molds, manufacturing prototypes, and testing them on vehicles. The company has streamlined this process by incorporating XAI and 3D printing and enhanced product precision.

XAI, an artificial intelligence technology, helps analyse and understand the causes and processes behind machine learning algorithms. NEXEN TIRE uses XAI to analyse various information related to tyre design, such as basic designs, key design variables, performance contributions, and design directions. This maximises design efficiency and helps propose optimal structures and designs that meet tyre developers’ requirements.

NEXEN TIRE leverages XAI-driven designs to create Virtual Tire Models, assessing product performance in virtual environments. This increases accuracy and speed in tyre development. The company’s recent decision to adopt a driving simulator will elevate virtual development further.

Once a model passes the virtual development stage, a physical prototype is produced for final evaluation, which requires mould production. NEXEN TIRE utilises 3D printing technology to make molds, enabling the simultaneous creation of prototypes in various designs and specifications. As these prototypes have already undergone verification in the virtual development process, the chances of final product approval are significantly increased.

Traditionally, mould production alone took two to three months, but with 3D printing, this period can be cut by at least 70%. Additionally, production costs can be reduced by at least 50%, ensuring cost efficiency from the early stages of development.

The 3D printing-based mould manufacturing technology allows for innovative tyre designs that include diverse and complex patterns and sipes. This is crucial for supporting high-performance vehicles and providing consumers with enhanced performance and safety. NEXEN TIRE has applied for an international patent for its 3D printing technology.

By innovating its development process, NEXEN TIRE enhances product competitiveness while reducing time and costs. The company also contributes to sustainable management by reducing waste and costs associated with discarded prototypes.

“The ultimate goal of our technological innovations is to enhance customer satisfaction.” A NEXEN TIRE representative stated, “Transforming the tyre development process not only secures market competitiveness but also contributes to environmental protection during the development process, shaping the future of tyre manufacturing and driving revolutionary change.”

Kimi Antonelli secured his maiden Formula 1 victory at the Chinese Grand Prix, becoming the first Italian driver to win a race since Giancarlo Fisichella in 2006. The Mercedes driver, who had already made history as the youngest-ever pole sitter, successfully converted his qualifying success into a race win. A key element of his triumph was the management of the Pirelli tyre compounds as he and the team opted for a one-stop strategy that proved highly effective.

The race began with an intense battle between the Ferraris and Mercedes, reminiscent of the season opener. However, Antonelli maintained his composure and used the restart following an early Safety Car to build a decisive advantage. While his rivals, including teammate George Russell and both Ferrari drivers, fought amongst themselves and lost precious time, Antonelli steadily extended his lead. Even after Russell managed to clear the Ferraris, Antonelli controlled the gap to secure victory, despite a minor error in the closing laps.

The Mercedes drivers executed their one-stop strategy flawlessly, starting on the medium Pirelli compound before switching to the hards under the Safety Car on lap 10. This approach was also adopted by the Ferrari duo and Oliver Bearman, who finished an impressive fifth. In contrast, Isack Hadjar employed a different tyre strategy. After a spin on the opening lap, he pitted for hards, then took advantage of the Safety Car to take another set of hards, which carried him to eighth place and valuable points for his team.

Lewis Hamilton completed the podium in third, finishing just ahead of his Ferrari teammate Charles Leclerc. The championship now heads to Japan for the next round at the renowned Suzuka circuit in two weeks. In support race action, Emma Felbermayr claimed victory in the second F1 Academy race in China, moving to the top of the standings ahead of Alisha Palmowski, who finished second ahead of Payton Westcott.

Dario Marrafuschi, Pirelli Motorsport Director, said, “Firstly, I would like to congratulate Kimi Antonelli on his first Formula 1 victory. It has been exactly 20 years since an Italian driver last triumphed in a Formula 1 Grand Prix, and this historic moment occurred today in a race filled with overtakes and plot twists. As expected, the one-stop strategy proved to be the most effective in Shanghai, and the teams did not change their approach even when a Safety Car neutralised the race on lap nine. Instead, the pit window for those who had started on Medium was brought forward.

“The final stint on Hards for 10 drivers exceeded 45 laps, with tyres that were clearly in the final stages of their wear yet still capable of maintaining decent consistency. In fact, the winner himself set the fastest lap of the race on lap 52. Those who had chosen the white-banded compound at the start, on the other hand, had the opportunity to stay out during the neutralisation, gaining a few positions. However, it didn’t take long for rivals with fresh tyres to reclaim the top spots.”

Alpine, Haas and Racing Bulls, for example, are teams that exploited these two strategies to create different opportunities for their drivers. Soft were also used at the start, with the Red Bull drivers taking advantage of the extra grip to attempt an early getaway as the lights went out. We can conclude that all three tyre compounds proved to be valid options for devising effective race strategies.”

The Yokohama Rubber Company has confirmed its tyre plant in Salem, Virginia, will permanently cease operations with effect from 18 March 2026. This decision follows consultations with the labour union, resulting in an earlier closure than anticipated. Initially, production was to be scaled back in March with a potential shutdown in July, but negotiations accelerated the timeline. The company has held discussions with suppliers and customers, assuring that the closure will not cause supply chain interruptions. Yokohama Tire Corporation, the company's US subsidiary, has coordinated these efforts. For the approximately 570 affected employees, Yokohama is providing outplacement support in cooperation with local agencies and the union.

The Salem facility began operating in the 1960s and has been part of Yokohama since the Mohawk Rubber Company acquisition in 1989. The closure stems from challenges posed by ageing equipment and outdated methods, which hinder meeting production goals focused on high-value-added premium tyres, including ADVAN and GEOLANDAR brands, winter tyres and those sized 18 inches and larger. The company aims to strengthen output and sales of these products.

This move aligns with Yokohama Transformation 2026, the medium-term plan running from 2024 to 2026. The strategy emphasises maximising premium tyre sales while optimising production systems across the group to ensure sustainable profitability and long-term growth. The Salem plant closure directly reflects these efforts.

Despite the shutdown, United States remains one of the most important markets for Yokohama. Since establishing its US sales subsidiary in 1969, the company has expanded its production and sales network through proactive efforts. Yokohama is committed to adapting to global shifts, promoting sustainable business expansion and contributing to the US economy and society. The company continues to respond to changes in the global business environment.

TyreSafe, UK’s charity dedicated to raising tyre safety awareness, has issued a reminder that underinflated tyres can lead to higher fuel consumption, a concern that is especially relevant given the current geopolitical pressures on global energy markets. With pump prices beginning to climb again across the UK, motorists are being encouraged to carry out basic vehicle maintenance as a way to improve fuel efficiency.

This week, motoring organisations including the RAC and AA have urged drivers to adopt efficient driving habits and ensure their tyres are properly inflated to mitigate the impact of rising costs. Recent RAC Fuel Watch data reveals a significant increase at the pumps, with petrol climbing by approximately 4.68p per litre and diesel rising by around 8.59p per litre in just over a week, coinciding with escalating tensions in the Middle East.

According to TyreSafe, checking tyre pressures at least once a month and before longer trips is essential. Drivers should refer to the manufacturer’s recommended levels, typically listed in the vehicle handbook or on a sticker inside the driver’s door frame or fuel cap.

Many motorists may not realise that driving on underinflated tyres could be silently increasing their fuel bills. Research from The Motor Ombudsman indicates that more than half of all tyres on UK roads may be running below the ideal pressure. This increases rolling resistance, meaning the engine has to work harder to maintain normal speeds.

Even a modest drop in pressure can have an effect. A 10 percent reduction can raise fuel consumption by about two percent, adding unnecessary costs. Safety is also compromised, as a 20 percent decrease can impair handling and grip, heightening the risk of incidents. With costs rising again, a simple tyre check can support both road safety and household budgets.

Stuart Lovatt, Chair of TyreSafe, said, “When fuel prices rise, drivers naturally look for ways to make their fuel last longer. One of the simplest things they can do is check their tyre pressures regularly. Underinflated tyres increase rolling resistance, which means the vehicle has to work harder and burn more fuel just to move forward. It may seem like a small issue, but over time it can quietly add to the cost of every journey. More importantly, tyres that are not inflated correctly can reduce grip, handling and overall vehicle stability. Keeping tyres at the correct pressure isn’t just about saving fuel – it’s a critical part of staying safe on the road.”
