The Yokohama Rubber has developed a proprietary system that utilises AI to predict the physical properties of rubber compounds. The system is already being used to design rubber compounds for Yokohama tyres. The company is expecting the system’s ability to conduct a large number of virtual experiments will enable it to accelerate compound development, reduce development costs, and develop better performing products. The system also will make it easier for less-experienced engineers to create new compounds.

The system was developed under Yokohama’s new AI utilisation concept, HAICoLab, which was launched in October 2020. The system uses AI to predict a rubber compound’s physical properties based on the rubber compound design parameters input by an engineer. In addition, to facilitate engineers’ ability to confirm predicted results, the system includes a function that displays the certainty of predicted physical properties and one that searches for a compound composition that will achieve physical properties closest to the targeted ones. The new system enables collaborations between humans and AI that will lead to the acquisition of new knowledge. Going forward, Yokohama Rubber will expand the use of this new system for developing rubber compounds for use in tyres to a wide range of the company’s other products, including hoses and conveyor belts.

HAICoLab is an acronym for “Humans and AI ColLaborate” for digital innovation. It also has the meaning of a laboratory for joint research by humans and AI. The new concept aims at fostering digital innovations by facilitating collaborative efforts that merge human inspiration and creativity with the enormous data processing capability of AI. Yokohama aims to acquire new knowledge by creating and collecting data based on hypothetical conditions set by humans and then applying AI to predict, analyze and then search for the most optimal result. Yokohama Rubber has been advancing technological developments by using AI in its material and tire design and development processes. For example, in 2017 Yokohama Rubber unveiled a new rubber material development technology that applies materials informatics and a tyre design technology that applies informatics technology. Under its new HAICoLab concept, Yokohama Rubber is now using AI to develop innovative products and services as well as processes. Through this effort, Yokohama Rubber will contribute to the realisation of “Society 5.0,” a future society that will enhance people’s experiences and take advantage of innovative technologies such as AI and IoT, as advocated by the Japanese government’s Cabinet Office.

Wider range of AI utilisation

Tyre Trends spoke with Dr Eng. Masataka Koishi, Executive Fellow, Head of AI Laboratory, The Yokohama Rubber Co.,Ltd, for more details on the new development.

What led to the development of HAICoLab concept? Will this be extended to other areas of R&D?

We have been pursuing a number of AI initiatives, but they are limited to certain areas. Moving forward, our desire to use AI in a wide range of fields led us to create HAICoLab as a framework to support more widespread use of AI in the future.

In addition to serving as the foundation of our future future efforts, I think it will also help communicate Yokohama Rubber’s stance on AI utilisation.

We believe that people will play the key role in achieving digital innovation, which will be achieved by applying AI to real and virtual data that is based on hypothesis setting that is derived from human inspiration and eliminates cognitive bias. This collaboration between humans and AI is what we are calling HAICoLab.

Prior to formulating HAICoLab, we were proceeding with technological developments using AI in our material and tyre design and development processes. In 2017 we announced a rubber material development technology that applies materials informatics and a tyre design technology that uses informatics technology. We are now working on the structures, materials, and production areas that will lead to innovative processes (design development) and products.

Developments in other areas are not yet at a stage where we can make any concrete public announcements.

Please comment on the R&D team. Is Yokohama working in association with any University, Research Institute etc?

We are applying the results of research conducted with universities and research institutes in Japan and overseas in our development of materials informatics and tyre design technology using informatics as well as to HAICoLab. Meanwhile, our effort to generate virtual data through simulations and analyse that data using machine learning is being carried out on supercomputers available through Japan’s High Performance Computing Infrastructure (HPCI) as well as our own supercomputers.

How is Yokohama proceeding to adopt AI in other areas of tyre development?

Similar to our effort with compounds, we are now making preparations for the use of AI when considering tyre design specifications. However, we are not yet at the stage where we can say anything more specific.

While developing new concepts, is Yokohama focusing on new innovations in the automotive sector? Kindly comment in detail

We believe that the tyres of the future will need to respond to the trends towards the application of CASE and IoT technologies in automobiles. Accordingly, we are developing new technologies that will accommodate CASE. For example, as previously announced at a press conference at the 46th Tokyo Motor Show held in 2019, in the CASE domain of connectivity we are conducting joint research and development with Alps Alpine with a view to creating a solution business that will supplement our existing tire air pressure detection sensor with the ability to detect tread wear and road-surface conditions and then use digital tools to process and manage the acquired data.

In addition, this February we announced our SensorTire Technology Vision, a medium- and long-term vision for developing new technologies for passenger car tyre sensors. By implementing this Vision, we aim to support people’s mobility and contribute to the safe and secure operation of motor vehicles while addressing the changes in mobility demand by providing data obtained from SensorTires (IoT tyres) fitted with sensing functions to drivers and businesses providing various automobile-related services.

Looking further into the future, we plan to connect this data collected by our SensorTires with map data and road traffic related information (traffic jams, weather conditions, etc.) to provide value-added information, such as proposals for safe driving routes, that will contribute to the safe operation of autonomous-drive vehicles as well as the operations of companies engaged in MaaS-related businesses. By anticipating the various changed being brought about by electrification of the automobile and quickly and appropriately expanding our product lineup, we hope to secure a dominant position in the evolving tire market.

Bekaert has flagged off its first fleet of LNG-powered trucks in India in collaboration with GreenLine, the country’s leading provider of sustainable heavy trucking solutions. The joint initiative is aimed at supporting India’s vision for a gas-based economy and reducing the carbon footprint of road logistics.

The foundation of the collaboration with GreenLine is a mutual dedication to operational innovation and ESG standards. Bekaert has the infrastructure required to trial this effort in Chennai and Halol, with plans to expand following a six-month learning period, thanks to GreenLine's LNG ecosystem, which is supported by real-time telemetry and a smooth refuelling network. It is anticipated that each LNG truck will save up to 24 tonnes of CO₂ a year, making a significant contribution to Bekaert's targets of 65 percent of sales coming from sustainable sources and carbon net zero by 2050.

Dinesh Mukhedkar, Procurement Operations Lead – South Asia and Procurement Global Shared Service Centre Lead, said, “As part of our purpose, ‘Establishing the new possible’, and our ambition to lead in safe, smart and sustainable solutions, decarbonising logistics is an essential step. Heavy-duty transport contributes nearly 90 percent of emissions in Indian logistics. Switching to LNG helps reduce CO₂ by up to 30 percent and particulate matter by up to 91 percent compared to diesel. GreenLine’s mission and integrated support made them the ideal partner. Together, we are shaping a cleaner, more sustainable future for logistics in India.”

Trelleborg Tires is all prepped up to debut the ART1000, its first agricultural rubber track for high-powered machinery, at the upcoming Agrishow 2025, the largest agribusiness trade show in Latin America. The company will also display its TM150 CFO tyre, which is developed for a new generation of sprayers, along with a wide selection of products designed for modern farming. The event is scheduled to be held from 28 April to 2 May in Ribeirão Preto (SP), Brazil.

Trelleborg Tires enters the agricultural rubber track market with the ART1000, a tyre designed for high-horsepower machines. In addition to optimizing vehicle economy and offering additional strength and long-lasting durability, the ART1000 is engineered for remarkable adaptability and mobility of agricultural machinery in all operating circumstances.

Goodyear Tyre & Rubber is conducting a strategic review of the farm tyre business at its Indian subsidiary, signalling potential changes as the US manufacturer evaluates its global operations.

The Indian unit disclosed in a regulatory filing that its board has acknowledged communication from its American parent regarding the review. Goodyear will be examining "all strategic, operational and financial opportunities" related to the agricultural tyre business, according to the statement filed under SEBI disclosure requirements.

The Ohio-based tyre maker has not indicated any specific plans or timeline for the review. The company cautioned that there is "no assurance that the strategic review will result in the implementation of any transaction."

This move is part of Goodyear's broader efforts to optimise its global portfolio amid challenging market conditions in the automotive sector.

As part of a strategic effort to increase its presence in the region's premium original equipment (OE) market, Kumho Tire has confirmed its plans to establish its first tyre production facility in Europe by 2027.

The company has shortlisted Poland, Serbia and Portugal as possible locations for the plant, which is projected to need an investment of more than KRW1 trillion (USD 705 million). The decision is closely linked to Kumho’s ambition to strengthen its partnerships with European automakers and was revealed by Kumho Tire CEO during the South Korean premiere of Kumho's new Ecsta Sport tyre line.

Kumho has recently secured OE supply contracts with major brands such as Mercedes-Benz, BMW and Volkswagen Group. At the moment, Kumho runs eight tyre production plants in China, Vietnam, South Korea and the US. Its capacity to compete in the premium OE market, however, has come to be perceived as being constrained by the absence of a European production base. Through the benefits of local production, the new facility will improve response to European client requests, save freight costs and shorten delivery times, all of which will strengthen the company's partnerships.
