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 European Tyre and Rubber Manufacturers’ Association (ETRMA), alongside 13 other European business organisations, has signed a Joint Statement urging the European Commission to ensure a strong and ambitious implementation of the Data Act.

The coalition, including numerous SMEs and Small Mid-Caps from the digital and industrial sectors of European companies, has urged the European Commission to uphold the regulation against pressure to dilute its core provisions, identifying it as a crucial framework for unlocking industrial data across the EU economy. The signatories contend that a robust implementation is vital for fostering a competitive market and unleashing innovation, particularly for smaller businesses.

The coalition highlights the Act’s benefits, which include empowering SMEs with data portability rights, protecting them from unfair contractual terms and mandating that data sharing occurs on fair, reasonable and non-discriminatory (FRAND) terms. A key provision requires cloud providers to facilitate switching through open standards, combating vendor lock-in. The statement expresses concern that lobbying efforts for delayed enforcement, weaker interoperability definitions and reliance on global standards without fairness guarantees threaten to undermine these objectives.

For the Data Act to be effective, the coalition insists on full implementation to open data markets to genuine competition and prevent SMEs from being excluded by legal complexity. The statement also calls for a proportionate approach, requesting practical guidance, standard contractual clauses and well-resourced enforcement authorities to support smaller companies. It notes that in certain sectors, supplementary legislation may be needed for full clarity.

The coalition concludes that strong enforcement is paramount, asserting that without it, the Act's rights will remain theoretical. They warn that any delay or softening of key provisions risks reinforcing the very market barriers the regulation was designed to eliminate. The signatories urge the Commission to ensure robust enforcement to secure a competitive and innovative Single Market for all companies.

CEAT Limited said on Thursday it would reduce prices across its entire tyre range following the Indian government’s decision to cut goods and services tax (GST) rates on tyres, with the full benefit being passed on to customers.

The Mumbai-based tyre manufacturer said new prices would take effect from 22 September, covering commercial, agricultural, passenger vehicle and two-wheeler segments.

India’s 56th GST Council meeting approved significant reductions in tax rates for the tyre industry. GST on new pneumatic tyres was cut to 18% from 28%, whilst tractor tyres and tubes will attract a reduced rate of 5%.

“We thank the Government of India and the GST Council for their timely and progressive decision to rationalise tax rates in the tyre sector,” said Arnab Banerjee, Managing Director & CEO of CEAT Limited.

“The reduced GST slabs will greatly benefit the tyre industry and consumers alike. Not only will it lower the cost of owning and operating a vehicle for customers across various segments, but by making tyres more affordable to replace, it will also make our roads safer.”

Banerjee added the move would “spur formalisation and greater compliance, while also fostering sustainable growth in the sector.”

The GST rate cuts represent a significant policy shift for India’s automotive sector, where high taxation has been a longstanding concern for manufacturers and consumers.
