Activities: Creating recycling technologies for products and raw materials

As a global manufacturer, we consider it our mission to contribute to the transition from a linear economy to a circular economy. We conduct R&D on materials with the goal of increasing the ratio of sustainable materials used in our products to 40% by 2030 and 100% by 2050. For example, by 2025, we plan to gradually launch products made of wear-resistant materials as well as recycled raw materials, such as recycled rubber and recovered carbon black from used tires. We are also developing technologies to reduce our use of petroleum-based materials, which have serious impacts on climate change, and to increase our use of biopolymers and renewable raw materials with smaller impacts.


(1) Supplying tires made of sustainable raw materials at Dakar Rally 2023

Toyo Tire Corporation has been supporting a team participating in the Dakar Rally since 2021. The Dakar Rally is known as the world’s toughest rally, taking two weeks to cover an approximately 10,000 km course on all kinds of terrain, including rocky stretches, deserts and mountainous regions. The race was held from December 31, 2022 to January 15, 2023, and the vehicle equipped with our tires won the production car category of the race.
The OPEN COUNTRY M/T-R tires mounted on the vehicle were designed for maximum performance to cover the whole distance on rough roads, with a structure that minimizes tire damage from driving impacts. We also used sustainable raw materials to reduce environmental impact. Of the tire components, the treads, carcass plies and sidewalls were mainly made of biomass-based butadiene rubber and styrene-butadiene rubber. Recycled bead wires were also used.
Going forward, we will apply the knowledge and experience we gained through the race in our product development and work to improve our technology for materials development, with the goal of achieving lower environmental impact together with higher performance and quality.

(2) Joint research with Osaka University wins award

Toyo Tire Corporation has been collaborating with academic research institutes on R&D of materials that may lead to the development of high-performance tires. Our study conducted with Osaka University since 2017 was awarded the 2021 JSME Kansai Academic Award by the Japan Society of Mechanical Engineers Kansai Branch. We received recognition for developing a method to accurately calculate power spectral density as an evaluation method for surface roughness and applying this method to the assessment of surface roughness of rubber samples. These findings enable the observation and evaluation of rubber surface roughness information across a wide scale, from micro to macro, and may potentially lead to the development of rubber materials with excellent grip force. Moving ahead, we will continue our initiatives aimed at streamlining development of high-performance tires that improve grip performance while also meeting fuel economy, durability and other performance demands from our customers.

(3) Successful synthesis of butadiene rubber from carbon dioxide: A significant step forward for the manufacture of tires using sustainable materials

In collaboration with the University of Toyama, we developed a catalyst that converts carbon dioxide into butadiene with high yield to synthesize butadiene rubber, a raw material for tires. Our success in pioneering the synthesis of butadiene from carbon dioxide, one of the main drivers of climate change that causes serious adverse impacts on the global environment, will help minimize our environmental impact in the production process (in terms of CO₂ emissions), compared to the existing method using petroleum-derived materials. Moving forward, we are undertaking development to gear up for mass production, with the aim of implementing the system by the end of the 2020s. We are also carrying out R&D on replacing other tire raw materials with sustainable raw materials.


Activities: Supporting safe driving (improving safety awareness through data)

We have been developing sensing technologies that collect various types of information from tires, which are the sole contact points with the road surface when driving a vehicle. The concept involves innovating and creating added value by using the tire itself as an information acquisition device. Sensors attached to the tires detect various data, which are then processed to derive the required tire performance limits. These sensing technologies make it possible to determine through data and visualization whether the tire force*2 in the running tires is within the performance range required for the road conditions. We are conducting pilot studies on public roads and car tracks, and working on its development as part of the necessary safety system for autonomous driving.

  • *2 Tire force is a term assigned by Toyo Tire Corporation that refers to actual tire performance as estimated from information input from the tire, such as air pressure, temperature, road surface distinction, load, wear and any detected. We developed an app to display tire force in real time to enable visual checking by the driver.

Activities: Enforcing intellectual property strategy

We are continuously developing technological innovations and products that help work towards a society that is environmentally sustainable and supports safe driving. We believe that it is only when these new technologies and products are delivered to our customers and are finally used that they first transform into social value. We develop recycled and renewable raw materials for sustainability, as well as rubber materials that achieve low fuel consumption. We also acquire intellectual property rights for these technologies so that our customers can use our products with peace of mind, backed by our technology. Furthermore, we believe that our ongoing efforts to enforce our intellectual property will help us secure our presence in a society of next generation of mobility.

[TOPIC] The 12th company-wide technology development presentation awards

At Toyo Tire Corporation, we develop technologies for practical application that meet the needs of our customers and clients, and that incorporate feedback from our production and sales divisions. Each year we hold the company-wide Technology Development Presentation to report to top management and announce our latest technological developments and the results of those initiatives. In 2022, the presentation was held online and assessed entries based on the five perspectives of originality, rationality, future potential, development speed, and presentation. This initiative will be continued in the future as we further our technological developments to continue responding to the needs of society.

2022 Awarded Topics

Outstanding Technological Development Award

Building a simulation technology for EV tire development

Wear resistance, low power consumption and quietness are considered as particularly important performances in EV tire development. We improved and expanded our existing simulation technology for friction energy, aerodynamics, rolling resistance and sound radiation, which are directly linked to these performances. Some of these technologies are already being applied to new products made for EVs that are currently under development. Using these as core technologies, we are working on building a platform that will enable us to efficiently develop suitable tires for EVs in the future.

Unique Award

Developing environmentally compatible antioxidant

Antioxidants are added to tires to protect tire raw materials against heat, ultraviolet rays and other causes of deterioration, and to prolong the service life of tires. Recently, researchers have reported that substances derived from amine antioxidants, the most widely used antioxidant, may adversely affect ecosystems, generating a need for alternative materials to these antioxidants. In this study, we used our proprietary technology for material design to develop an antioxidant made from sustainable raw materials.

Surprise Award

Developing predictive maintenance technology using acoustic emission (AE) wave measurement

At our manufacturing plants, stable production is hampered by failure or stoppage of core equipment. There is a need for a predictive maintenance technology that will detect equipment abnormalities early to prevent these incidents. The topic of this presentation is to find equipment abnormalities at an early stage by detecting the AE waves emitted when scratches, cracks and other plastic deformations occur in equipment bearings and gears, with the hope that this will lead to better predictive maintenance.
