Realising ‘IoT Tyres’ means installing various sensors inside of a tyre in order to collect and transmit information from the tyres to the vehicle, where this information can then be used in various applications. As these sensors require batteries or other sources of energy to operate, we believe that it makes perfect sense to power these devices using the energy produced naturally by the rotation of a tyre: Kazuhisa Fushihara, Manager, Planning & Administration Dept.,  Research & Development HQ, Sumitomo Rubber Industries

Cutting edge technology researches are on overdrive to enhance the performance of a tyre that can fit into the future definition of mobility, which revolves around sustainability. Tyre as a totally autonomous entity even while being the most vital element in a vehicle is among the ultimate goals of designers and technologists – tyres that can operate on its own, depending less on the mother vehicle, ensuring safety to the user and adding high level of value to strengthen the vehicle’s performance.

Surface friction and rolling resistance have always been the focus of tyre makers. A high amount of heat and energy are being generated during a tyre’s roll on the surface. Making use of this to sustain its function has been a major aim of technologists. Sumitomo Rubber Industries’ (SRI) “Energy Harvester” answers to this effort in a big way.       

In mid 2019, Sumitomo, through joint research undertaken with Professor Hiroshi Tani of Kansai University, developed this new technology to generate electric power from the rotation of a tyre. This is accomplished by installing a power generating device (Energy Harvester) inside of a tyre to convert static electricity occurring within a tyre into clean energy. This new device takes advantage of a type of static electricity called “frictional charging” to generate electric power efficiently each time a tyre's footprint deforms as a tyre rotates. Sumitomo, the     parent company of Falken Tyres, believes that this technology holds great potential for practical applications as a power source without needing batteries for various automotive digital tools, including in TPMS (Tyre Pressure Monitoring System) and other automotive devices.

The research was selected by the Japan Science and Technology Agency, national research and development agency, as a Type FS Seed Project under A-STEP (Adaptable and Seamless Technology Transfer Program through Target-Driven R&D). Sumitomo Rubber Industries will now advance this research with support from the Japan Science and Technology Agency.

 Sumitomo has been engaged in a wide range of joint research studies with various universities, including Kansai University and Gunma University Center of Research among others, on sustainability projects.

Regarding the project on “The Development of Intelligent Tyres Using Friction-Charged Sensors,” Kazuhisa Fushihara, Manager, Planning & Administration Dept.,

Research & Development HQ, Sumitomo Rubber Industries, told Tyre Trends: “We are afraid that we are unable to comment on the scope of this joint research project, or other areas of joint research with Kansai University, due to the existence of a non-disclosure agreement. However, we can say that, with backing from the Japan Science and Technology Agency (JST), we are actively engaged in research and development that envisions future tyres that fully incorporate IoT technology.

‘In-house’ energy source

On Energy Harvester Technology, Fushihara said that “Kansai University carried out the basic research and development for the underlying technology before engaging in joint research and development with our company toward realising applications for this technology in tyres.

Developing energy sources within tyres/vehicles goes a long way in ensuring sustainability in product manufacturing. The degree of energy saved is directly proportional to the reduction of energy used from external sources, including fossil-based sources.  

Fushihara said: Realising “IoT Tyres” means installing various sensors inside of a tyre in order to collect and transmit information from the tyres to the vehicle, where this information can then be used in various applications. As these sensors require batteries or other sources of energy to operate, we believe that it makes perfect sense to power these devices using the energy produced naturally by the rotation of a tyre.”

Maintaining right pressure in tyre plays a major role in its performance. “We believe that tyre pressure monitoring systems are an enormously beneficial technology, which is why the EU, China and many other countries around the world have followed the lead of the United States in making TPMS a regulatory requirement. Maintaining appropriate tyre pressure is extremely important in terms of both safety and the environment and, with an eye toward the future of automated vehicles, we believe that it is safe to say that TPMS will only become more and more important in the coming years,” Fushihara observed.

He added: “In the future, we hope to add even more value to these kinds of systems by augmenting their functionality so that they are able to detect not only tyre pressure, but also conditions at the point of contact between tyre and road as well as tyre load and other operational factors.”

Sensing Core

“The Sensing Core Technology that we are currently developing is yet another example of the Sumitomo Rubber Group’s efforts to enhance the value of TPMS so that we may provide greater safety and peace of mind to the increasingly automated mobility society of the future.”

The Sensing Core, a new tyre sensing technology, can detect road conditions, tyre load and other information by analysing the wheel speed signals that are generated by the rotation of the tyres.

SRI has already perfected its proprietary DWS (Deflation Warning System) technology, which analyses wheel speed signals from the rotation of tyres to detect and notify the driver of decreases in tyre air pressure. The DWS technology has been adopted by many automobile manufacturers and can now be found as a factory standard feature in countless vehicles throughout the world, the company website said (information and image courtesy: srigroup.co.jp).

Based on the technical knowhow that SRI cultivated in the development of DWS, the Sensing Core is the next evolution in DWS technology, an advancement that eliminates the need for an additional, dedicated sensors by instead utilising cutting-edge software to detect tyre pressure directly from existing wheel speed signals, thereby reducing the cost of installation and eliminating the need for maintenance.

As the only part of a vehicle that comes into direct contact with the road, tyres must support a vehicle’s entire weight. The Sensing Core technology uses a proprietary algorithm to detect various types of information based on what we know about each specific tyre so that this information can be shared with the driver and with the vehicle itself. This advanced algorithm incorporates and takes full advantage of SRI’s extensive knowledge of various tyre properties, which the company gained through over 100 years of experience in tyre development.

Dunlop (company name: Sumitomo Rubber Industries, Ltd.) has secured the first commercial deployment of its SENSING CORE technology in China. The system's ‘tyre load detection’ and ‘tyre air pressure detection’ functions have been adopted by Chongqing Ruichi Automotive Industry Co., Ltd. (Ruichi) for its new electric commercial vehicle model, the Ruichi C5. This marks both the technology's entry into the Chinese market and the global debut of Dunlop's tyre load detection capability.

The load detection function monitors changes in cargo weight and distribution in real time, feeding data to the vehicle's control system. This reduces driving instability during starting, stopping and turning caused by shifting loads, thereby lessening driver burden and enabling more stable cargo transport. The feature is scheduled for implementation in additional Ruichi models going forward.

This development responds to conditions in China's urban areas, where e-commerce growth has fuelled demand for short-distance delivery services while autonomous driving and driver assistance features gain traction. In vehicles equipped with advanced systems, control logic typically operates based on predetermined load parameters. When actual loads deviate from these assumptions, discrepancies arise that affect driver comfort and cargo stability. Commercial vehicles therefore increasingly require smooth acceleration and deceleration control that remains effective regardless of load conditions.

Ruichi selected Dunlop's technology as an effective solution to these challenges. The system requires no additional sensors and can be installed without modifying existing vehicle configurations, offering significant cost advantages. SENSING CORE analyses wheel speed data alongside vehicle control information from the CAN data stream to detect various conditions including tyre pressure, tread wear and load.

On the Ruichi C5, the load detection function assesses total weight on left and right tyres for front and rear axles according to changes in cargo volume and position. This data optimises torque output during acceleration and brake control based on current load conditions, delivering stable ride quality unaffected by load changes during frequent urban deliveries.

Dunlop pursues this work under its SMART TYRE CONCEPT development philosophy, which aims to deliver high safety and environmental performance for CASE and MaaS applications. SENSING CORE anchors these services and is planned as the company's fourth major business pillar alongside tyres, sports and industrial products.

The challenges of frequent starts and stops during urban deliveries and changing load conditions extend beyond China throughout Asia, including Japan. Building on this adoption, Dunlop aims to expand its presence in both domestic and international markets.

Refurbished tyre-recycling machines are emerging as a practical answer to rising compliance pressure and capital constraints across the sector. As demand grows for faster, lower-cost capacity expansion, Revyre Global’s decision to release a complete, operational processing line highlights how secondary equipment markets are becoming strategically relevant to recyclers.

Refurbished machines are finding renewed demand in the tyre-recycling industry as processors look to expand capacity quickly without the capital burden and long delivery cycles of new equipment.

Against this backdrop, New Zealand-based recycling firm Revyre Global is releasing a suite of previously used, fully operational machinery from its tyre-recycling line, offering other recyclers access to proven processing systems spanning shredding, separation and granulation, along with critical spares to support uninterrupted operations.

Speaking to Tyre Trends exclusively, Chief Executive Officer Shaun Zukor noted, “Demand for refurbished tyre‑recycling equipment is expected to increase as global EPR regulations intensify and scrutiny grows around whole‑bale tyre handling. Many operators are seeking leaner, downsized plant and equipment configurations to meet compliance requirements while reducing capital expenditure. As regulatory pressure mounts, refurbished systems present a practical and cost‑effective solution for meeting mandated recycling obligations.”

The equipment sale aligns with Revyre’s broader strategy to expand capacity and scale into new markets, particularly in roading and water-proofing applications where demand for high‑quality recycled polymer products is growing rapidly. These sectors require higher production volumes and upgrading to next‑generation technology positions the company to fulfil those larger‑scale opportunities.

The line for sale can produce approximately two tonnes per hour of product, which is standard with current smaller operational outputs. The new processing line’s output is highly adaptable and could be rapidly configured to produce a range of materials based on market demand.

“This flexible production capability allowed the system to switch between product types without significant downtime or reconfiguration, enabling throughput levels that aligned competitively with industry standards. The ability to modify production on demand ensured efficient utilisation of capacity under varying operational requirements,” explained Zukor.

The primary target buyers of the company are new market entrants with vertically integrated operations, particularly those managing tyre‑collection networks. Such buyers can benefit from processing tyres earlier in the value chain, improving transport efficiency by reducing bulk volume and lowering the need for extensive pre‑processing at the final facility. This machinery offers an accessible entry point for organisations seeking scalable, cost‑efficient recycling capability.

TURNING THE BLADES

According to Zukor, Revyre’s existing mechanical tyre‑shredding system faced significant operational constraints due to its reliance on multiple moving components, which resulted in frequent breakdowns, high maintenance costs and extensive downtime.

The traditional multi‑stage process viz-a-viz shredding, rasping and grinding required substantial manual supervision and labour input, creating both inefficiencies and higher operating expenditure. These limitations collectively hindered scalability and consistent production performance, prompting the shift to more advanced and efficient technology.

“The next‑generation system offers a markedly more automated process that consolidates material reduction into a single grinding stage. This significantly reduces maintenance requirements, labour dependency and risk of mechanical failure. The improved system delivers higher throughput rates, more consistent and higher‑purity output materials and substantially lower contamination levels. In addition, improved energy efficiency across the system contributes to lower operational costs and a more sustainable processing footprint,” explained Zukor.

While all used equipment carries inherent operational risks, the system on sale recently underwent a repair and replacement of key wear components. “With proper upkeep, the line is expected to deliver at least another 10 years of reliable performance. The sale package includes spare parts and maintenance support to help buyers manage operational continuity and compliance requirements,” added Zukor.

He also noted that providing reliable, industrial‑grade equipment lowers capital barriers and reduces development time for new entrants. Furthermore, by extending the lifecycle of existing machinery, Revyre reinforces the principles of circularity, effectively recycling the recycling equipment, which is aligned with the organisation’s mission and sustainability values.

Currently, the company is actively advancing towards fully automated, digitally controlled recycling systems to reduce human exposure to mechanical processes and improve operational safety.

Increased automation will also reduce labour overheads and enables more consistent, globally competitive production output, supporting its long‑term vision of efficient, technology‑driven resource recovery.

“This upgrade is a major step towards establishing Revyre as a leader in high‑value polymer recovery, enabling production of superior‑grade materials for roading, water-proofing and masterbatch applications. Enhanced quality, scalability and process efficiency will strengthen our circular‑economy partnerships including potential collaborations with tyre manufacturers seeking reliable, high‑performance recycled inputs,” noted Zukor.

Revyre’s equipment sale underlines a broader shift in tyre recycling where affordability, compliance and speed to market matter as much as technology. By extending machinery lifecycles while upgrading its own capability, the company reflects an industry increasingly viewing refurbished systems as both an economic and circular solution.

Bridgestone has marked a significant advancement in its pursuit of digital mobility solutions with the activation of a cutting-edge driving simulator at its European R&D facility near Rome. The VI-grade DiM500 Driver-in-the-Loop (DiL) simulator represents a major step forward in the company’s virtual tyre development capabilities, allowing for the evaluation of tyre performance without the need for physical track testing.

The simulator is built around a large, mobile platform capable of moving up to five metres, enabling it to replicate the dynamic forces experienced in real-world driving. Housed within a carbon-fibre cockpit, the driver is immersed in a hyper-realistic virtual environment, and the system’s extensive range of motion ensures that the forces simulated are comparable to those measured during physical trials. This setup allows for highly accurate assessments of tyre behaviour.

By combining high-fidelity simulation with live driver feedback, historical data and artificial intelligence, Bridgestone can now explore a much wider array of tyre specifications earlier in the design phase. This approach accelerates design decisions and reduces the reliance on physical prototyping. Consequently, traditional track testing can be reserved for the final validation stages. This shift is expected to deliver substantial environmental benefits, with a projected annual saving of up to 12,000 experimental tyres. It builds on the company’s existing Virtual Tyre Development technology, which has already reduced raw material use and CO2 emissions in the original equipment development phase by as much as 60 percent.

Beyond environmental gains, the technology shortens development timelines by enabling simultaneous tyre and vehicle engineering. This parallel process fosters closer collaboration with automotive manufacturers, allowing Bridgestone to tailor tyres more precisely to the performance characteristics of specific vehicle models. While the simulator is currently focused on dry handling scenarios, its capabilities are being extended to cover a broader spectrum of driving conditions. Supported by continued investment in global research and development, this initiative reinforces Bridgestone’s capacity to adapt to the evolving demands of both manufacturers and drivers.

Mattia Giustiniano, Senior Vice President – R&D, Bridgestone West, said, “Bridgestone is already considered a pioneer in digital tyre development – leveraging Virtual Tyre Development for more than a decade. By integrating the driver into the digital development cycle, this investment adds a crucial new piece to our evolving ecosystem. The simulator’s introduction marks a significant step in enhancing the efficiency and sustainability of our R&D processes while unlocking unprecedented opportunities to foster innovation.”
