Activities: Environmental contribution

Reducing the CO₂ emissions of vehicles is a challenging issue that needs to be addressed across the supply chain. At Toyo Tire Corporation, our goal is to help reduce greenhouse gas (GHG) emissions per tire by 20% by 2030 compared to 2019 levels. To cut CO₂ emissions of vehicles caused by running tires, we set the reduction of tire rolling resistance as a top priority and included improving the fuel efficiency grading of tires as a development requirement for product model changes. Taking life cycle assessment into consideration, we are also developing environmentally oriented products with better energy efficiency and resource savings.

Advancements in fundamental rubber materials technology

We are seeing signs of rapid change in the area of materials development as AI and machine learning start to be employed. We have been engaged in continuously innovating Nano Balance Technology, our proprietary platform technology for rubber materials development. It includes technologies for predicting rubber material properties and aiding in composite design using materials informatics (MI).*1
Since 2018, we have been using our accumulated existing data assets to verify technologies predicting tire composition and physical properties using MI technology. To achieve high-performance product development while at the same time shortening development lead times and reducing costs, we have been working on creating an environment where we can make full use of our stored data for development work using prediction data and analysis methods from an entirely new perspective.
Currently, we are applying these data stores to actual development to help create differentiated products that fulfill multiple performance requirements to a high level. Those requirements include higher fuel efficiency and better wet-grip performance that can be achieved by using highly dispersed silica and new materials.

Building the technology for virtual development

We have been working on building the technology for virtual development by improving the accuracy of estimates of tire characteristics on paper and establishing an efficient workflow for assessing actual vehicles. In addition to using this technology for centralizing data management, improving the accuracy of estimates of basic dynamometer characteristics and constructing tire models, we are working to adapt it to other items for actual vehicle performance estimation. These initiatives enable shorter development periods as well as reduce the number of prototypes and actual vehicle assessments, thereby helping cut CO₂ emissions in the development process.

Developing weight reduction technology

We are developing weight reduction technologies and rolling out products for each category of tires for passenger cars, light trucks, and trucks and buses. To achieve our medium-term target of reducing tire weight, we have been working on reducing the thickness of components, considering new structures, and improving the work process capacities of our plants. In particular, we have already started developing products with weight reduction technology using high-precision equipment at our Serbia Factory last year, and plan to expand this initiative in the future.

[TOPIC] PROXES Comfort IIs: Premium comfort tire developed in pursuit of superior cruising experience and advanced environmental performance

PROXES Comfort IIs is a premium comfort tire that was developed in pursuit of superior cruising experience and advanced environmental performance. Using our proprietary T-MODE tire design platform technology, we adopted an asymmetrical pattern in designing the tread in order to provide different functions within the tread pattern*2. By optimizing the pattern design on the inner and outer sides of the tire, we were able to reduce the noise energy generated by the tire pattern by 22% compared to our previous model (PROXES C1S), ensuring a high level of quiet comfort in the cabin interior. In addition, we increased the stiffness of tread blocks to improve steering stability and reduce drift when changing lanes, providing a balance between high-quality ride comfort and steering stability.
For material development, we developed a fuel-efficient compound using our platform technology for material design, Nano Balance Technology. We used a new silica dispersing agent to more evenly disperse silica, a material that effectively reduces rolling resistance and improves wet-grip performance and wear resistance, making it possible to achieve optimally high levels of performance for these features.

Activities: Safety

Tire wear forecasting system to boost customer safety

The Technology Development Division and the DX Promotion Division are collaborating on an application that can diagnose tire wear based on information about the usage status of truck and bus tires. The teams are conducting trials by asking customers to try out the app so they can improve the accuracy of their predictions and expand the range of functions to facilitate the remote confirmation of air pressure and wear prediction results. This technology enables us to help improve the safety of drivers and passengers by encouraging customers to appropriately rotate their tires based on the wear predictions. We also expect it will have environmental benefits by extending tire life and increasing the possibility of reuse as retread tires.*3

Achieving long product life and superior braking performance on wet surfaces

To develop technologies that protect the safety of customers by improving product life and superior braking performance on wet surfaces, we have been installing new facilities and modifying evaluation equipment with the aim of raising the level of tire measurement, analysis and evaluation technologies. We are working on visualizing the behavior of tires with tire wear and when braking on wet surfaces, and developing new design elements. The design elements we obtain from this process will be rapidly applied to our products to help ensure the safety of our customers.

[TOPIC] PROXES Sport 2: Premium sports tire delivering high levels of handling and braking performance

PROXES Sport 2 is a premium sports tire that delivers the high levels of handling and braking performance required of sports tires. An asymmetrical tread pattern* and compound are used to segment different functions and effectively improve braking and handling performance.

Silica, which contributes to rubber flexibility, is evenly dispersed in the compound at the inner side of the tread, allowing the tires to touch the ground in a supple manner on uneven road surfaces and improving grip performance on both wet and dry surfaces. Meanwhile, silica dispersion is controlled in the compound at the outer side to ensure rubber stiffness.

For its structural design, we adopted a new profile to optimize side deflection and control tire deformation when changing lanes or cornering. This helps improve handling performance on both wet and dry surfaces.

Activities: Commercializing airless tires

Our “noair” airless concept tire is designed to facilitate maintenance-free, no-spare solutions that satisfy the needs of the next-generation mobility society in which people opt for self-service gas stations, home charging of electric vehicles and more prevalent car sharing. In 2017, noair became the first tire in the industry to demonstrate a level of performance that enabled it to be installed and driven on a passenger vehicle by achieving a level of durability and maneuverability that is close to that of pneumatic tires. We installed the noair tires on golf carts and conducted test drive events in 2022 as part of our efforts to facilitate their practical use. We are paying close attention to the formulation of laws and regulations regarding airless tires as we consider installing them on futuristic mobility vehicles and using them in recycling operations.
