Japanese tyre major the Yokohama Rubber Co in joint-research with Dr. Bo Nils Johan Persson have successfully developed in December 2024, the world’s first theoretical model to predict the rubber wear-rates on uneven road surfaces and the size distribution of wear particles.

Dr Persson is a leading a leading expert in the study of rubber friction and contact, contact, friction, wear and lubrication, including rubber friction. He is associated with Peter Grunberg Institute (Germany) and Lanzhou Institute of Chemical Physics (China).

He also runs a company called Multiscale Consulting (Germany) that supports companies in the rubber industry and beyond in addressing various challenges.

What’s more Dr. Persson’s unique approach to contact mechanics and rubber friction have been documented in numerous peer-reviewed academic journals and verified by other scientists, proving its effectiveness in solving a wide range of problems.

The new research was selected as the most noteworthy item and featured as the cover story in the 21 February 2025 edition of ‘The Journal of Chemical Physics’ published by the American Institute of Physics.
Yokohama Rubber known for its extensive track record in rubber research and advanced technological development capabilities, entered into a contract with Multiscale Consulting to collaborate with Dr. Persson in studying friction and wear on rubber and road surfaces.

The partners successfully developed what they claim is the world’s first theoretical model for multiscale (ranging from nanometre to centimetre levels) rubber wear behaviour on uneven road surfaces, for which theorisation had been difficult in the past. Experiments measuring rubber wear behaviour when sliding in both dry and wet conditions at different contact pressures and sliding speeds showed that the theoretical model’s predictions of wear-rates (mass loss per unit of sliding distance) and size distribution of wear particles aligned closely with the experimental results, confirming that the model could be used for such predictions.

Going forward, Yokohama Rubber plans to continue conducting research with Dr. Persson and Multiscale Consulting in order to pursue the development of tyres with high-level wear resistance.

In addition, Yokohama will continue to focus on reducing tyre wear, which is a leading demand for EVs to have reduction in environmental issues.

Bridgestone India announced the winners of the 5th Edition of its Mobility Social Impact Awards (MSIA) 2025 in Pune, celebrating organisations that use mobility for social good.

The top honour in the Road Safety Innovation and Excellence category went to ALERT (Amenity Lifeline Emergency Response Team) from Chennai for empowering over 450,000 citizens with emergency response skills. Safety Research Foundation (SRF), based in Pune, received a Jury Commendation for its BRACE Project, which transforms school zones with safety audits and infrastructure upgrades.

In the Empowerment of Vulnerable Communities category, The Association of People with Disability (APD), Bengaluru, won the top honour for its Rehab on Wheels initiative, which provides last-mile rehabilitation services.

The winners were presented with their awards by social worker Dr. Girish Kulkarni, founder of Snehalaya.

Hiroshi Yoshizane, Group President, Bridgestone Asia Pacific and Managing Director, Bridgestone India, said: “It is a privilege to honour these changemakers who are redefining mobility for social good. Their work reflects our shared commitment to building inclusive, safe, and empowered communities.”

Jeya Padmanaban, Founding Trustee, Safety Research Foundation (SRF), said, “We are truly honoured to receive the Jury Commendation at the Bridgestone Mobility Social Impact Awards 2025. The BRACE Project reflects our belief that road safety must begin at the community level, where awareness and infrastructure meet action. This recognition strengthens our resolve to continue building safer environments for children and fostering a culture of responsibility and care on our roads.”

German synthetic rubber maker ARLANXEO has launched consultations with worker representatives over the potential closure of its Port Jerome facility in France, citing persistent weak demand and declining competitiveness in the European chemicals industry.

The company, which is majority-owned by Saudi Aramco, had begun an information and consultation period with the Works Council at the site, located in northern France. A final decision on the closure will be taken after the mandatory consultation process concludes and approval is obtained from the French labour authorities, DREETS.

“The European chemical industry continues to face persistent weak demand and declining competitiveness driven by rising costs, unbalanced global markets, and increased regulatory pressure,” said Stephan van Santbrink, ARLANXEO chief executive.

“These conditions have generated a significant burden on the sector across the regional value chain. ARLANXEO has not been an exception to these challenges. The Port Jerome site has remained in a structurally loss-making position. Despite numerous improvement efforts, we do not foresee a viable path to a sustained structural improvement.”

The company did not disclose how many jobs would be affected by a potential closure, nor did it provide details on the facility’s production capacity or annual output.

Van Santbrink acknowledged the impact on workers, saying: “We recognise the impact a potential closure may have on our employees, and we regret the need to consider these steps. We will continue to treat all employees with respect. If we decide to cease operations at the site, we will do our utmost to assist in finding alternative solutions for all impacted employees. In addition, we intend to provide impacted employees with a social plan which reflects their valued contribution to ARLANXEO.”

The announcement adds to a growing list of European chemical producers struggling with high energy costs, sluggish demand and competition from lower-cost producers in Asia and the United States.

ARLANXEO said it would work closely with all affected internal and external stakeholders to minimise the impact of the intended closure.

Continental's Tires group sector has strengthened its leadership team with two key internal appointments, effective 1 September 2025. Jana Striezel has been named the new head of global purchasing for Continental Tires, while Dennis Bellmund has assumed leadership of the global original equipment business for both passenger and commercial vehicles. Both executives will report directly to Christian Kötz, the member of Continental AG's Executive Board who leads the Tires group sector.

In her new capacity, Striezel will oversee worldwide strategic and operational purchasing. She brings extensive experience from the automotive industry, having previously held several procurement management roles at Renault, where she led purchasing for the Renault brand and its alliance with Nissan and Mitsubishi in Europe. Her career began at Volkswagen in 2014.

Bellmund, who has a 25-year tenure with Continental, steps into his role following the departure of his predecessor, Manja Greimeier, to the ContiTech sector. His extensive background within the company includes recent responsibility for Continental’s tyre retail operations, alongside prior leadership roles in EMEA supply chain management and sales direction for the European replacement tyre business. These appointments signal a strategic reinforcement of Continental's tyre division leadership.

Kötz said, “We’re delighted to welcome Jana Striezel, a highly skilled manager, to our team. She brings extensive expertise in international procurement and will focus on driving forward our purchasing strategy. In Dennis Bellmund, our global original equipment business has gained a highly experienced leader. Thanks to his many years at Continental, he is familiar with our company and our customers’ needs from many different angles. On behalf of the entire management team, I wish both of them every success in their new roles and look forward to working together.”

“On behalf of the entire team, I would like to thank Manja Greimeier for her successful leadership of our original equipment business and wish her all the best and continued success,” added Kötz.
