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.

Gaurav Kumar has resigned as a whole-time director of Apollo Tyres, the Indian tyre manufacturer, after more than two decades with the company, though he will remain chief financial officer during a transition period.

The Gurugram-based company's board approved the resignation at a meeting on Thursday. Kumar steps down as a director, and consequently as a member of the risk management committee, with effect from the close of business the same day. The company said he had confirmed there was no material reason for his departure beyond that stated in his resignation letter.

Kumar will continue as chief financial officer for such period as is necessary to ensure a smooth transition, after which he will cease to be part of the company's senior management.

In his resignation letter, Kumar said: "It has been terrific to be part of the incredible journey at Apollo Tyres thus far. I have learned, and hopefully contributed in equal measure, and now seek to explore alternative and new challenges. I wish Apollo Tyres the very best for the journey ahead and will always be part of the Apollo Tyres Family." He added that he was grateful to Onkar Kanwar and Neeraj Kanwar for their support during his tenure of more than 22 years at the company.

Neeraj Kanwar, Vice-Chairman and Managing Director, said: "Gaurav deserves kudos for the critical role he has played in the growth of Apollo Tyres, both in India and overseas, in the last twenty years. While we do regret losing him, we are conscious of his personal aspirations and wish him the very best in his future endeavours."

The company said it was in the process of appointing a new chief financial officer.

Shrader Tire & Oil (STO) has announced the appointment of Bob Feldbauer to the role of President, effective 1 August 2026. He will concurrently serve as Chief Operating Officer, while Joe Shrader maintains his position as Chief Executive Officer.

Feldbauer’s ascent follows his arrival at STO in early 2025 as Chief Operating Officer, a role built upon a robust industry resume. His prior engagements include a lengthy stint at the helm of Jack’s Tire & Oil in Utah and a substantial period with Michelin North America, where he handled sales and managerial assignments.

Under the new structure, Feldbauer’s purview widens to encompass both internal fleet management across 14 sites and outward-facing commercial development, including alliances and market expansion. With the founding family’s fourth generation now active within the firm, the succession plan reinforces the enduring principles established when the company opened in 1948.

Shrader said, “Bob has proven exactly what we hoped he would when we brought him on board – sharp operational instincts and a real drive to help this company grow. Putting him in the President seat lets us move faster on the growth plans we’ve been building towards.”

Feldbauer said, “It has been a fast year and a half at Shrader Tire & Oil. I have gained tremendous insight and valuable knowledge about our organisation’s structure, company culture and an understanding of our overall goals and commitments. One thing is clearly obvious – the commitment Shrader employees have to deliver the best customer experience each and every time. I appreciate this and look forward to supporting them as their President and COO.”

Balkrishna Industries Ltd. (BKT) has unveiled a brand installation at the Mumbai International Airport Limited (MIAL) T2 Elevated Road Underpass as the tyre manufacturer seeks to broaden its positioning beyond its traditional Off-Highway business and strengthen awareness of its expanding on-highway portfolio in India.

The 2,000 sq. ft. installation, inspired by the company's "Elevate Your Drive" philosophy, highlights BKT's portfolio across agriculture, construction, mining, earthmoving, commercial vehicles, two-wheelers and passenger vehicles. The activation comes as the company expands its presence in India's two-wheeler and commercial vehicle tyre segments.

Designed to move beyond conventional outdoor advertising, the installation features nine illuminated tyre-shaped displays, each 8 feet in diameter, using the tyre itself as the central storytelling element. It opens with a large-format visual featuring BKT brand ambassador Ranveer Singh, followed by a sequence of displays illustrating the company's expanding mobility portfolio. The installation will remain at the airport for 24 months.

Mumbai International Airport handled a record 55.5 million passengers in 2025, providing the company with sustained visibility among business travellers and consumers.

"For BKT, innovation goes beyond product engineering; it extends to how we tell our story. This installation reflects a simple yet powerful idea: our tyre itself becomes the medium through which travellers experience the breadth of BKT's world. As we expand our presence across India's mobility landscape, it is important that consumers see BKT not through a single product category, but as a brand that supports movement across diverse terrains, applications and journeys. Mumbai Airport provides an ideal stage for us to express that transformation in a memorable and distinctive way," said Satish Sharma, Senior President & Director – Business Development and Strategy, BKT.

The installation was conceptualised by Infectious Advertising and uses immersive design, sequential storytelling and its airport location to showcase the company's wider mobility portfolio. According to BKT, the activation is intended to connect its established Off-Highway business with its growing presence in India's on-highway mobility market.

Mumbai-headquartered leading carbon black manufacturer Epsilon Carbon has reported a 10 percent reduction in carbon dioxide equivalent emissions across its upstream transportation operations during FY2025–26. The reduction was achieved through the deployment of an electric and liquefied natural gas freight fleet.

An independent third party certified the emissions data. The reductions achieved in transport logistics equate to carbon absorption figures associated with approximately 29,000 trees. The verified figures allow supply chain partners to include these reductions within Scope 3 emissions reporting frameworks and environmental disclosures.

Gaurav Mathur, Chief Executive Officer, Epsilon Carbon, said, “Decarbonising logistics is central to our climate strategy. What makes this milestone meaningful is that the results are independently verified with a 10 percent reduction in CO2e emissions within the upstream transportation category over a single financial year, driven by the adoption of electric and LNG fleets. These carbon reductions strengthen our own sustainability disclosures and those of our customers, and we intend to scale this model across our supply chain.”

Following Phase 1 operations, Epsilon Carbon intends to expand the number of electric and LNG vehicles in its transport fleet during FY 2026–27 to scale low-carbon freight transport across its supply chain network.
