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.

TyreSafe, UK’s charity dedicated to raising tyre safety awareness, has launched a new seasonal campaign warning British drivers that spring rainfall poses a hidden danger often overlooked after the harsh winter months. The initiative, named ‘Drip Drip Drop – ‘Little’ April Showers’, focuses on the rising threat of aquaplaning as more vehicles return to roads that remain treacherously slick from sudden downpours.

National data shows that poor tyre maintenance is a leading cause of fatal incidents, with three quarters of car tyre defects linked to neglect. Research further reveals that at 70 miles per hour (approximately 112 kmph), worn tyres add 27 metres to the standard wet stopping distance, an increase of nearly 30 percent compared to the Highway Code baseline.

Incorrect tyre pressure compounds the problem significantly. Underinflated tyres struggle to channel water away, overheat more quickly and extend braking distances, while overinflated tyres reduce the tyre’s contact patch and compromise grip. Spring’s fluctuating morning and evening temperatures make pressure changes especially common during April.

Even tyres above the legal minimum tread depth can fail in heavy rain. Continental Tyres’ research found that at 50 miles per hour, tyres with 1.6 mm of tread required 6.9 metres longer to stop than new tyres with 8 mm tread, whereas those with 3 mm added 2.7 metres. Light rain after dry spells mixes with oil and debris, creating conditions where worn or incorrectly inflated tyres lose all steering and braking control.

With bank holidays, leisure travel and outdoor activities increasing during longer daylight hours, TyreSafe urges motorists not to assume the worst weather has passed. April showers arrive without warning, and the combination of winter road grime and sudden rainfall can turn a routine journey into a dangerous aquaplaning event within seconds. TyreSafe urges road users to embrace the simple ACT protocol: regular checks of air pressure, condition and tread depth.

Stuart Lovatt, Chair of TyreSafe, said, “April showers might sound harmless, but when they hit busy roads and combine with worn or incorrectly inflated tyres, the consequences can be devastating. Aquaplaning can happen in seconds and without warning. The research is clear – poor tyre maintenance dramatically increases stopping distances in wet conditions. That’s why we’re urging road users to ACT: check your Air pressure, inspect the Condition and monitor your Tread. A few minutes of checks could prevent a lifetime of consequences.”

Mitas has officially entered a three-year agreement with the National Tractor Pullers Association (NTPA), marking a significant commitment to one of North America’s most extreme motorsports. The partnership, set to run from 2026 through 2028, designates Mitas as the Official Agriculture Tire sponsor of the championship and Title Sponsor of the Mitas National Finals Pull-Off.

Tractor pulling represents a severe test of both raw power and engineering precision. Competitors pilot highly modified machines to drag a heavy sled down a dirt track, with resistance increasing incrementally until only the strongest and best-prepared vehicles remain. Success depends entirely on transferring massive horsepower to the ground under extreme conditions, where tire grip and consistency frequently determine the winner. The NTPA season includes over 60 events across United States, running from spring through early fall, with deep roots in the Midwest. As an official partner, Mitas will gain prominent visibility on and off the track while actively supporting the growth of the sport.

Central to this collaboration is the Mitas PowerPull tyre, a product specifically engineered for tractor pulling to convert raw engine output into winning performance. Designed to manage extreme torque and deliver maximum grip, the PowerPull functions as a slick tyre that permits teams to cut custom tread patterns based on track conditions and individual race strategy, providing a measurable competitive advantage.

The season will conclude with the Mitas National Finals Pull-Off, the championship’s premier event where the year’s top competitors vie for national titles. Scheduled for 18 and 19 September 2026, in Urbana, Ohio, the finals serve as the ultimate showcase of performance, innovation and passion. As title sponsor, Mitas deepens its connection to the pulling community by attaching its name to this marquee competition.

Roberta D’Agnano, Global Marketing Director Mitas at Yokohama TWS, said, “The collaboration with NTPA connects Mitas to two worlds where performance truly matters: tough daily work in the field and the most extreme competitive environments. Tractor pulling is the ultimate expression of what farmers face every day – delivering power to the ground, staying consistent under pressure and performing when limits are pushed.

“Performance isn’t just about winning on the track – it’s about delivering results when it counts most, whether in competition or on the farm. In tractor pulling, every component is tested to the extreme, just as it is in real agricultural operations. That’s why we feel a strong connection with this community. The NTPA community embodies passion, resilience and a nonstop drive to push boundaries; values that are core to the Mitas brand. We’re excited to be part of this world, learning from these extreme conditions and turning that knowledge into tyres that perform where it matters most for farmers and pullers alike.”
