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 Tire Industry Project (TIP) has initiated a pilot study in collaboration with the Greater Paris Sanitation Authority (SIAAP) and the sustainability consultancy ERM to assess the potential of wastewater treatment plants to remove tyre and road wear particles. The research is being conducted at the Valenton wastewater treatment facility near Paris, which ranks as Europe’s second-largest plant and features advanced treatment technologies representative of modern municipal systems. This investigation is scheduled to continue through 2026.

In numerous urban centres globally, stormwater and road runoff are channelled into wastewater systems prior to being discharged into natural waterways. A clearer understanding of how effectively these treatment processes capture TRWP could guide the broader adoption of optimised wastewater management practices. Currently, systematic data quantifying the removal of these particles within treatment plants remains scarce, and this project aims to generate comprehensive, end-to-end evidence to bridge that knowledge deficit.

The study represents TIP’s first real-world application of a priority mitigation strategy identified in its white paper on addressing tire and road wear particles. Over the coming months, researchers will collect and analyse samples from key stages of the Valenton plant’s treatment cycle using advanced pyrolysis gas chromatography-mass spectrometry. The findings are expected to estimate the total removal efficiency across the entire process and will be submitted to a scientific journal, with publication anticipated in early 2027.

The scientific understanding of TRWP is complicated by a lack of standardised methodologies, the variable nature of the particles and their transformation products, and the diverse environmental pathways they traverse. In response, TIP and its member companies have committed to advancing research on quantification, characterisation, environmental migration and potential impacts while collaborating with value-chain stakeholders to support science-based interventions. A 2024 TIP publication reviewed over 50 mitigation measures and prioritised nine based on upstream and downstream potential, employing a prevention, containment and removal framework.

That review also concluded that no single measure has been proven effective specifically for TRWP and that on-ground validation is essential. Moreover, the paper stressed that no universal solution exists, requiring coordinated, large-scale implementation across multiple actors, including the tyre, road construction and automotive sectors, as well as municipal authorities, academia and other public and private entities. The Valenton pilot thus marks TIP’s inaugural effort to test wastewater management’s real-world efficacy, uniting diverse stakeholders from both the public and private sectors in this critical research.

Larisa Kryachkova, Executive Director, TIP, said, “This pilot is an important step in going beyond understanding the subject in the laboratory to field-based evidence. We expect to identify best practices that can be applied far beyond this project, supporting TIP’s ambition to support science-based mitigation.”

Sabrina Guérin, Head of Innovation Department, SIAAP, said, “As the public authority responsible for wastewater treatment in the Paris region, SIAAP is committed to emerging science that protects waterways. By taking part in this TIP study, we will gain an early, science-based view of TRWP movement in solid waste. The findings can help inform and accompany future treatment planning and readiness for upcoming regulatory requirements.”
