The Automotive Tyre Manufacturers’ Association, the apex body representing automotive tyre manufacturers in the country, has announced its new leadership structure.

The apex tyre body has elected Arun Mammen, Vice Chairman & Managing Director of MRF as the new Chairman of ATMA and Hiroshi Yoshizane, MD, Bridgestone India as the new Vice-Chairman of ATMA.

The appointment comes at a crucial juncture as ATMA celebrates 2025 as its Golden Jubilee year.

Mammen hold a graduate degree from the Madras Christian College and MBA from the Ashland University, US. He became the Managing Director of MRF in 2004 and Vice Chairman and Managing Director in 2017.

He believes that the Indian tyre industry should strive to be a major global manufacturer in the next decade and he will work on policy enablers to make the industry more competitive and technologically superior for meeting the needs of developed countries.

ATMA highlighted that given the global push towards carbon emission, there is a clear need to reduce carbon footprint in manufacturing and supply chain among others. The tyre industry on its part is already investing towards regenerative and recycled raw materials, along with using clean energy and reduction in water usage in manufacturing.

Furthermore, the INROAD Project as an industry initiative is expected to further add 200,000 hectares of new rubber plantation in the next two years.

“Over the next five years, focus needs to be given to upgradation of quality and training of the stakeholders,” added Mammen.

Nokian Tyres has named Formula 1 legend Kimi Räikkönen as its newest brand ambassador. This strategic partnership unites two Finnish powerhouses celebrated for excelling under extreme pressure. The company, a world expert in tyres for harsh conditions, aligns perfectly with Räikkönen, the famously cool and accomplished champion known as ‘The Iceman’.

For Nokian, this collaboration is a move to significantly amplify its international recognition. The brand gains a universally respected figure whose persona embodies the resilience and high performance intrinsic to its products. Räikkönen, whose celebrated career includes 21 Grand Prix victories and a World Championship, brings immense credibility and a global following.

Räikkönen notes a personal connection to the iconic Finnish brand, remembering it from his earliest days in motorsport. In his role, he will actively promote Nokian Tyres' capabilities to a worldwide audience, helping to convey their expertise in mastering the most demanding driving conditions on the planet.

Räikkönen said, “Perfect match, great to start working with Nokian Tyres, a brand I remember from the days when my parents drove me to karting tracks, before I even had a driver's license. In my opinion Nokian Tyres is an iconic Finnish brand, I'm excited to start spreading the good news about the great tyres to the world.”

Tiina Frazer, VP for Brand, Marketing and Communications at Nokian Tyres, said, “Some collaborations just make sense, and this is one of them. Kimi Räikkönen and Nokian Tyres share the same DNA: Finnish roots, uncompromising performance and the ability to thrive under pressure.

Bridgestone will introduce two new premium passenger car tyres in Japan next year, expanding its Potenza line as demand grows for products that offer both high performance and everyday usability. The company said it will release the Potenza RE-71RZ and Potenza Adrenalin RE005 in February 2026, with 61 and 40 sizes available respectively.

The RE-71RZ is positioned as a high-grip tyre for drivers who want strong performance on both circuits and public roads. Bridgestone said the model delivers faster lap times and better handling than its predecessor, the RE-71RS. At the Tsukuba Circuit 2000, the company recorded a 1.2% improvement in lap time compared with the previous model.

Professional drivers Masahiro Sasaki and Yuji Tachikawa supported the development work. Sasaki said, “As its strong point, ‘POTENZA RE-71RZ’ achieves a high level of performance in both grip and controllability. It delivers improved dry and wet performance for street use, while also achieving faster lap times and better wear resistance on the circuit. This tire delivers high performance in various situations, making it enjoyable and easy to handle for both everyday driving and circuit use.”

Tachikawa added, “This tire is designed for easy handling, allowing anyone to experience precise control along with excellent grip. The tire is focused on quick warm-up for immediate, high-grip performance as well as reliable wet grip, resulting in a well-balanced tire suitable for various driving conditions.”

Bridgestone said the RE-71RZ uses a new compound developed with motorsport know-how and its NanoPro-Tech technology, as well as a redesigned tread pattern and structure aimed at improving grip and wear resistance.

The Potenza Adrenalin RE005 targets a broader range of vehicles, including everyday passenger cars. It is intended for drivers seeking sharper handling in daily use while maintaining fuel efficiency and ride comfort. All 40 sizes meet the “A” grade for wet performance under Japan’s tyre standards, and 19 sizes also achieve an “A” grade for rolling resistance.

The company said the tyre offers stable handling at higher speeds, cornering confidence and better wet braking, supported by upgraded compounds, an A-shaped tread motif and structural changes that reduce energy loss.

Both products are expected to be sold in overseas markets after their launch in Japan.

Bridgestone said the new tyres reflect its long-running approach of using technologies developed in motorsport to improve products for road use. The company added that the Potenza brand will continue to support “safe and enjoyable car and motorsports culture” as part of its long-term E8 Commitment.
