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.

The Alliance for the Future of Tires (AZuR) has confirmed its participation as a cooperation partner for the tyre material flow for an interactive event on the Digital Product Passport (DPP), scheduled for 16 June 2026 at the Bottrop campus of Ruhr West University of Applied Sciences. With the European Union planning to introduce DPP from 2028, the initiative aims to establish greater transparency, resource conservation and functional material cycles. The upcoming gathering will focus on practical applications and future prospects for industry, trade, recycling and the circular economy.

The European Union has classified tyres as a priority product group under the new Ecodesign Regulation. The digital passport will provide accessible data on a tyre’s entire lifecycle, including material composition, carbon dioxide emissions, repair history, retreading suitability and recycling methods, potentially via QR codes or radio-frequency identification technology on the tyre itself.

Significant potential exists for the tyre recycling sector. Retreaders will be able to quickly assess casing history, mileage and past repairs to determine suitability for retreading. Recyclers will gain improved material transparency regarding ingredients, additives and recycled content, thereby facilitating both mechanical and chemical recycling. Thus, the passport can support longer tyre use and more efficient recovery of valuable raw materials.

AZuR views DPP as a key step towards advancing the tyre circular economy. Several manufacturers are already working on pilot projects, including Michelin’s coordination of a scalable system through the CIRPASS-2 project, standardisation efforts by Bridgestone and Michelin via the Global Data Service Organisation and AZuR partners’ work on radio-frequency identification and digital traceability. The upcoming university event offers companies, researchers and municipalities an early opportunity to address the passport’s requirements and develop practical solutions.
