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.

Toyo Tire Corporation said Mitsubishi Corporation has ceased to be a major shareholder after tendering its entire holding through a treasury share buyback, ending its status as the company’s largest shareholder.

The change took effect on 10^th August , 2026, following Toyo Tire’s acquisition of its own shares through off-auction trading (ToSTNeT-3). Mitsubishi tendered all its shares, excluding less than one unit, as part of the transaction.

As a result, Mitsubishi is no longer classified as a major shareholder or associated company of Toyo Tire, the company said.

Before the transaction, Mitsubishi held 30,822,206 shares, equivalent to 20.07 percent of total voting rights, and ranked as the largest shareholder. Following the change, its holding has effectively been reduced to zero.

The move follows Toyo Tire’s earlier announcement on August 7, 2026 regarding the termination of its capital and business alliance with Mitsubishi, alongside plans to repurchase its own shares.

Toyo Tire said the change would have no impact on its consolidated financial results.

TyreSafe, UK’s charity dedicated to raising tyre safety awareness, has joined forces with Sussex Police’s Road Safety Team to introduce a pioneering digital reference tool for frontline officers. The initiative equips police with immediate, device-accessible tyre safety data during roadside stops.

Developed as a local pilot, the application enables consistent vehicle examinations and improves driver communication regarding tyre dangers. It offers specific checklists for diverse vehicle categories, including motorcycles, cars, heavy goods vehicles, light commercial vans and towed trailers. The system further incorporates guidance on part-worn tyres, common queries and educational talking points.

Following its Sussex trial, the programme holds potential for nationwide adoption across UK police forces. This deployment underscores Sussex Police’s dedication to roadway innovation and reinforces the essential contribution of proper tyre maintenance to overall public safety.

Stuart Lovatt, TyreSafe Chair, said, “This partnership with Sussex Police is a landmark moment for tyre safety enforcement and education. By putting reliable, accessible tyre safety guidance directly into the hands of frontline officers, we can ensure safer vehicles on our roads and help prevent avoidable collisions and breakdowns. Sussex is leading the way, and we hope this model will soon be adopted nationally.”

Superintendent Jo Grantham, Head of Roads Policing, Sussex Police, said, “Our officers are committed to keeping road users safe, and having instant access to this tyre safety resource makes a real difference on the ground. It supports enforcement while also giving us the tools to educate drivers more effectively. We’re proud to be working with TyreSafe on this project and to be the first police force in the country to pilot it.”

The UK Towing Safety Alliance (UKTSA) has published a comprehensive four-year analysis of incident data from National Highways’ Strategic Road Network, covering 2022 to 2025. The findings reveal a 23 percent rise in total towing-related incidents, driven primarily by a maintenance crisis affecting utility and commercial trailers. While traffic collisions involving towed vehicles decreased by 17 percent, mechanical breakdowns now constitute 77 percent of all towing-related incidents, highlighting vehicle and trailer condition as the sector's foremost challenge.

The data coincides with SMMT Motorparc 2025 figures showing Britain's vehicle fleet at its oldest recorded level, with average car age reaching 9.7 years. The summer harvest season has also arrived, bringing agricultural trailers back to roads after months of disuse. NFU Mutual research indicates collisions involving agricultural vehicles are 56 percent more likely between May and September, reinforcing the need for pre-journey roadworthiness checks.

Utility and agricultural trailers now account for nearly half of all towing-related callouts, surpassing 3,000 incidents in 2025. Regionally, the North West has overtaken the South East as the most incident-prone area, with trailer failures surging 60 percent since 2022, while the North East recorded a 55 percent increase. A growing divide exists between leisure and commercial towing sectors.

Leisure sector improvements, including fewer horsebox incidents and regional caravan reductions, suggest awareness campaigns are yielding positive results. However, utility trailer failures continue climbing, indicating maintenance standards across commercial and domestic sectors require greater attention. Regular servicing, correct loading and proper coupling remain essential to prevent avoidable incidents.

For working trailers, summer represents peak operational period, with agricultural and utility trailers seeing intensive use while rural roads become busier with tourists and cyclists. The Alliance emphasises that trailers stored for extended periods require thorough inspections before returning to service.

The UKTSA urges all towers to perform three essential checks covering tyres, load and connection before every journey. Tyres must be inspected for pressure, tread and deterioration; loads correctly distributed and couplings and electrical connections verified. The Alliance will place ‘The Working Trailer’ at the centre of safety campaigns, collaborating with industry partners to boost maintenance awareness and reduce preventable breakdowns across the Strategic Road Network.

A spokesperson for the UK Towing Safety Alliance said, “It’s encouraging to see fewer collisions involving towing vehicles, which suggests that drivers are becoming more aware of safe towing practices. However, that progress is being undermined by a growing number of preventable mechanical failures. The challenge is no longer simply about how people tow – it’s increasingly about what they’re towing and the condition it’s in. As both tow vehicles and trailers get older, regular maintenance has never been more important.”

Stuart Lovatt, Chair of TyreSafe, said, “Harvest season places extra demands on both vehicles and trailers, particularly those that may only be used for a few months each year. One of the most common issues we see is tyres that appear to have plenty of tread but have deteriorated through age, weathering or prolonged storage. Whether you’re towing a livestock trailer, plant trailer, horsebox or caravan, tyres should always be inspected for correct pressure, damage, cracking and signs of ageing before every journey. A few minutes spent carrying out these checks can prevent breakdowns and significantly improve safety for everyone using our roads.”

Sarah Smithurst MBE, COO, National Trailer & Towing Association (NTTA), said, “Across the NTTA network, we’re seeing a noticeable increase in enquiries from people looking to refurbish older trailers or source second-hand trailers, including imported models, as a more affordable alternative to buying new. While extending the life of a trailer is often entirely appropriate, it’s essential that owners understand that trailers are not maintenance-free. Many have been in service for years, sometimes decades, and components naturally deteriorate over time, even if the trailer has seen relatively little use. Every trailer should be thoroughly inspected before it returns to the road, with particular attention paid to tyres, brakes, bearings, couplings and lighting. Investing in regular servicing and maintenance is far less costly than experiencing a breakdown – or worse, being involved in an incident. The NTTA continues to help and advice new and old trailer users about safety and many are asking for help when towing, especially the reversing aspect of a trailer, now the B&E test was withdrawn. We are also seeing more trailers being repatriated from North America and Europe rather than purchasing new in the UK.”
