The Yokohama Rubber Co., one of the leading tyre manufacturers globally, has announced that it has succeeded this month in developing a proprietary tyre design support system that uses eXplainable AI (XAI).

This enables it to create the desired tyre features by supplementing the knowledge and experience of development staff while also making it easier for less-experienced staff to design tyres. In addition to getting new insights and inspirations to the development of products and performance, it also leads to reduction in development time and costs. 

Yokohama states that the new tyre design support system was created to make its tyre development process more innovative and is based on its HAICoLab AI utilisation concept, which was launched in October 2020. 

How does tyre development happen?

The tyre development begins with a search for features (design factors that determine the tyre’s material, shape, and structure) that will improve the its characteristic values (numerical values and indicators that represent performance and quality) and achieve the development goals. 

Yokohama’s new tyre design support system was developed using a customised version of XAI called SHAP (SHapley Additive exPlanations), which provides developers with the features that can be useful for realising the desired tyre characteristics. 

In addition, the system provides multifaceted indicators that make it easier for developers to understand how to adjust the obtained features. The system will enable less-experienced developers to efficiently develop new tyre designs.

XAI uses the standard specifications and targeted characteristic values set by development staff to determine the targeted characteristics that need to be improved and related quantitative values.

They further interpret the information presented by XAI (features that can be useful for realising the desired tyre characteristics) from multiple perspectives and modify the specifications. The staff then applied the characteristic value estimation AI developed by Yokohama Rubber in 2021 to check whether each characteristic value was achieving the targeted level. The final specifications are determined after repeating this process, and XAI is able to confirm the basis for each of these specifications — the design factors (features) that help improve or maintain each characteristic value and its contribution rate. 

This collaborative effort between humans and AI generates new discoveries and inspirations that will lead to the development of products with higher performance levels.

The Japanese major plans to use this system to develop a wide range of tyre products and broaden the applicable areas of its HAICoLab.
HAICoLab is a framework that aims to realise digital transformation by merging the unique inspiration and creativity of humans with AI’s enormous data processing capability. 

The resulting human-AI collaborations enable people to interpret, analyse, and judge AI-generated results without being trapped by preconceptions and cognitive biases by incorporating perspectives from outside from their own field of expertise and opinions different from their own that supplement their own extensive experience, knowledge, and assessment criteria.

Maxion Wheels has graduated the first Indian cohort of its Formare vocational education programme and launched a second intake, marking the expansion of the initiative into Asia.

The programme, introduced in India in 2024 through a partnership between the Iochpe Foundation of Brazil and Savitribai Phule Pune University (SPPU), combines classroom education with practical manufacturing training for students from underprivileged communities.

Twenty-six students enrolled in the inaugural cohort, with 23 completing the programme and receiving a diploma in Manufacturing Technology. Those who continue for a third year at SPPU will be eligible for a university graduation certificate.

According to Maxion Wheels, 87 percent of the graduates will begin their professional careers at the company's Pune operations.

"The graduation of our first Formare class in India is a proud and meaningful achievement, both for our students and for Maxion Wheels," said Sutheep Ratnabhas, President of Maxion Wheels' Asia Business Unit. "This programme reflects our belief that investing in education and skills development can transform lives while strengthening our communities and our business. We are especially encouraged and fortunate to see these young professionals beginning their careers with us."

The company also inaugurated the programme's second cohort, comprising 27 students, including six women, who account for 22 percent of the intake.

The ceremony at SPPU was attended by Mark Sinar, Vice President, Global Human Resources and Safety & Sustainability at Maxion Wheels, Rahul Vaidya, Managing Director of Kalyani Maxion Wheels, university representatives and the families of graduating and incoming students.

Graduates described the programme's impact on their personal and professional development.

"Formare has given me the confidence, skills, and opportunity to build a better future for myself and my family," said Aman Mulla. "I am proud to start my career with Maxion Wheels and excited for what lies ahead."

Abha Kamble said: "This programme opened doors I never thought possible. The combination of learning and hands-on experience has prepared us for real-world challenges."

Originally established by Brazil's Iochpe Foundation, the Formare programme has operated for more than three decades and has trained more than 28,000 young people. Maxion Wheels said it plans to introduce the programme in Türkiye later this year.

Tyres Europe and the Association of Synthetic Amorphous Silica Producers (ASASP) have released a joint position paper on synthetic amorphous silica (SAS) in tyre manufacturing. The document highlights SAS as a critical component that improves wet grip, reduces rolling resistance and supports durability, thereby enhancing vehicle safety, fuel efficiency, electric vehicle range and lowering use-phase emissions.

A proposed harmonised classification for SAS is under consideration. Though not an outright ban, the industry warns it would likely compel manufacturers to phase out SAS during design rather than manage exposure, effectively bypassing practical risk controls.

Tyres Europe and ASASP urge regulators to base any action on robust evaluation of SAS properties, exposure conditions, established industrial uses and broader socio-economic impacts on European value chains. Policy measures must reflect these factors to avoid unintended disruptions.

Tegeta Green Planet participated in the recent Social Design Days conference, a three-day event hosted by the Design Institute that centred on circular design and sustainable innovation. The gathering brought together diverse professionals to explore the intersection of creative disciplines and environmental responsibility.

During the proceedings, Tegeta Green Planet Director Shalva Akhvlediani engaged in a panel discussion that examined Georgia’s trajectory in building a circular economy. The conversation addressed the nation’s current obstacles and prospective avenues for growth, with a particular focus on systemic shifts in resource management and regulatory frameworks.

Akhvlediani pointed to measurable advancements in Georgia’s waste management infrastructure, the adoption of Extended Producer Responsibility standards and a growing national recycling ethos. These developments, he observed, are creating a robust base for more judicious resource utilisation and fostering habits of conscientious consumption. The panel further acknowledged that resourcefulness is deeply rooted in Georgian heritage, where mending, reusing and bequeathing goods were traditional practices, though modern consumerism has eroded these customs, necessitating a blend of age-old wisdom with contemporary circular strategies.

A critical takeaway from the discussion was the assertion that technological fixes and legislation alone are insufficient. Genuine progress, Akhvlediani argued, hinges on synergistic cooperation between designers, architects, researchers and creatives to engineer products and systems that prioritise longevity and recyclability from inception. Social Design Days proved instrumental in facilitating cross-sectoral dialogue, promoting circular principles and inspiring actionable solutions for national sustainability. Tegeta Green Planet reaffirmed its dedication to advancing these environmental objectives and supporting collaborative platforms that drive meaningful change.
