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.

Cleanmax Bets On Hybrid Renewables As Tyre Makers Accelerate Decarbonisation

CleanMax

As India’s industrial sector accelerates its shift towards cleaner energy, tyre manufacturers are emerging as a critical test case for integrating renewable power into continuous, high-load operations. In this conversation, Kuldeep Jain, Founder and Managing Director of CleanMax, outlines how demand from companies such as CEAT and Michelin is reshaping renewable procurement – from conventional solar contracts to hybrid, round-the-clock solutions – while positioning clean energy as both an operational necessity and a strategic lever for decarbonisation.

Industrial decarbonisation in India is entering a more operational phase, where renewable electricity is no longer a peripheral lever but an embedded component of manufacturing strategy. For CleanMax, this shift is most visible in energy-intensive sectors such as tyre manufacturing, where continuous processes, global supply-chain pressures and ESG commitments are converging to reshape how power is procured and consumed.

Kuldeep Jain, Founder and Managing Director of CleanMax, describes a market moving beyond cost arbitrage towards structural integration of clean energy. Demand from tyre manufacturers – long characterised by high, stable electricity loads – is now influencing both project design and procurement models, pushing developers towards hybrid and round-the-clock renewable solutions. 

Energy-intensive industries are increasingly prioritising renewable electricity to manage power costs and reduce operational emissions. Manufacturing sectors with continuous loads are particularly suited to long-term renewable procurement models such as group captive and open-access PPAs, which provide cost stability while supporting decarbonisation goals,” Jain says.

That demand is already translating into project pipelines. CleanMax’s collaboration with CEAT involves developing 59 MW of hybrid wind-solar capacity to supply renewable power to its Halol and Kanchipuram plants. Similarly, its engagement with Michelin includes an open-access solar power purchase agreement supporting operations at the company’s Chennai facility.

“These projects illustrate how large industrial consumers are integrating renewables into their long-term energy strategy. For instance, globally, the International Energy Agency has already noted that industrial electrification and renewable procurement will drive the next phase of the energy transition. Tyres are firmly in that wave,” Jain notes.

FROM INTERMITTENT SUPPLY TO ENGINEERED RELIABILITY

Tyre manufacturing presents a distinctive challenge for renewable integration. Plants operate continuous processes – mixing, curing and vulcanisation – that require stable baseload electricity and thermal energy. Traditional solar PPAs, while cost-effective, are inherently intermittent, limiting their suitability for such operations.

The industry is therefore evolving towards hybrid models that combine multiple renewable sources. “Hybrid projects are gaining traction because they smooth generation across the day, improving plant load factors,” Jain says. According to the International Renewable Energy Agency, such hybrid systems are among the fastest-scaling formats for industrial decarbonisation.

“As a result, the industry is moving beyond single-source solar PPAs towards wind-solar hybrid projects and open-access group captive models that provide higher plant load factors and more balanced generation profiles across the day. Wind-solar hybrid is increasingly seen as the most practical and efficient pathway to scale renewable penetration in continuous manufacturing environments,” Jain explains.

This shift reflects a broader reframing of renewables – not as intermittent substitutes for fossil fuel power but as engineered systems tailored to industrial demand curves. The emphasis is on aligning generation profiles with consumption patterns, rather than expecting operations to adapt to variable supply.

SECTOR-SPECIFIC DECARBONISATION PATHWAYS

Not all heavy industries decarbonise along the same trajectory. Jain draws a clear distinction between tyre manufacturing and sectors such as cement or steel, where process emissions form a significant share of the carbon footprint.

“If you step back, industries don’t decarbonise in the same way because they don’t consume energy in the same way. A tyre plant is largely powered by electricity. So if you clean up the electricity, you’ve already addressed a meaningful part of its emissions,” he says.

However, the challenge lies in reliability. “These are continuous operations. They don’t switch off when the sun sets or the wind drops. That’s why hybrid becomes important, as a way of shaping energy to demand,” Jain adds.

“In case of cement or steel, a significant portion of emissions comes from how the product itself is made. So the shift we’re seeing is subtle but important. It’s about redesigning the energy profile itself so that clean energy isn’t intermittent in theory but dependable in practice,” he continues.

The implication is that electrification-driven sectors such as tyre manufacturing can achieve faster decarbonisation gains through renewable procurement, provided supply reliability is addressed through hybridisation and system design.

ESG, PRODUCT STRATEGY AND COMPETITIVE POSITIONING

Renewable energy is also assuming a more strategic role within tyre companies’ ESG frameworks. What began as a cost-management exercise is increasingly tied to product innovation, sustainability reporting and global competitiveness.

“The conversation around renewable energy in the tyre industry has clearly evolved beyond cost optimisation. Many manufacturers are increasingly integrating renewable power into their broader ESG strategies and supply-chain decarbonisation commitments, particularly as global automotive OEMs push for lower-carbon sourcing across the value chain,” Jain says.

This transition is evident at the product level. CEAT’s launch of its SecuraDrive CIRCL tyre – produced with up to 90 percent sustainable materials – signals how manufacturers are aligning product design with sustainability objectives.

“Renewable electricity procurement helps reduce Scope 2 emissions and supports the development of lower-carbon products, which is becoming an important factor in both sustainability reporting and global competitiveness. As a result, renewable energy is now seen not only as a cost-management tool but also as a strategic lever for product decarbonisation and ESG positioning,” Jain explains.

TECHNOLOGY MIX AND OPERATIONAL ALIGNMENT

From a systems perspective, no single technology provides a complete solution. CleanMax advocates a portfolio approach that combines generation assets with digital tools and flexible contracting structures.

“A portfolio approach works best. For manufacturing operations with steady electricity demand, hybrid renewable systems combining solar and wind have proven effective, as the complementary generation profiles improve overall availability and plant load factors,” Jain says.

Digital energy management platforms play a supporting role by optimising dispatch and aligning supply with consumption patterns. Flexible procurement structures, including open-access and group captive models, further enhance adaptability across sites and regulatory regimes.

“In practice, hybrid setups combining solar and wind have proven effective because they smooth generation across the day and improve overall availability. That’s what makes renewable power usable at scale,” Jain adds.

The CEAT and Michelin projects exemplify this approach, integrating multiple procurement pathways – onsite solar, offsite generation and open-access PPAs – to increase renewable penetration without compromising operational stability.

POLICY VARIABILITY AND MULTI-LOCATION STRATEGIES

India’s regulatory landscape remains heterogeneous, with state-level policies shaping the feasibility and economics of renewable procurement. For tyre manufacturers operating across multiple locations, this creates both complexity and opportunity.

“Overall, the ecosystem is steadily evolving to support higher renewable penetration practically. Open-access mechanisms are becoming more aligned with industrial needs. Renewable procurement is naturally becoming more location-specific,” Jain says.

Different state frameworks enable companies to tailor their energy mix – combining onsite solar with offsite wind or solar depending on regional resource availability and regulatory incentives.

“In practice, this leads to more balanced and resilient energy portfolios. This is also where developers with experience across markets can add value by structuring solutions that are aligned to each site’s load profile, regulatory context and long-term cost objectives, rather than taking a one-size-fits-all approach,” Jain explains.

GLOBAL SUPPLY CHAINS AND RISING EXPECTATIONS

Pressure from global automotive OEMs is accelerating the adoption of renewable energy in India’s tyre sector. As manufacturers integrate more deeply into international supply chains, emissions performance is becoming a criterion for sourcing decisions.

“As tyre manufacturers become more integrated with global OEM supply chains, expectations around emissions are becoming more defined. Renewable electricity is one of the more immediate ways to address this, especially for Scope 2 emissions,” Jain says.

“What we’re seeing is more about alignment – companies are adapting their energy mix to stay relevant in global markets, where sustainability is increasingly part of how sourcing decisions are made,” Jain says.

This dynamic is likely to intensify as OEMs tighten decarbonisation targets and extend accountability across their value chains, reinforcing the role of renewable energy in industrial competitiveness.

THE NEXT FRONTIER: TRACEABILITY AND CARBON MARKETS

As companies move towards net-zero targets, the focus is broadening beyond direct emissions to include value-chain impacts and verification mechanisms.

“Instruments such as renewable energy certificates and carbon markets help companies transparently account for the renewable electricity they procure. At the same time, there is growing focus on Scope 3 reporting as manufacturers work to address emissions across their broader value chains and align with global supply-chain decarbonisation expectations,” Jain says.

Traceability – ensuring that renewable energy claims are verifiable and auditable – is expected to become increasingly important, particularly for export-oriented manufacturers facing stringent disclosure requirements.

A DECADE OUTLOOK: ACHIEVABLE, BUT CONDITIONAL

Looking ahead, Jain is cautiously optimistic about the pace of renewable adoption in India’s tyre manufacturing sector. The fundamentals – declining costs, expanding capacity and supportive policy evolution – are largely in place.

“Over the next decade, higher renewable penetration in tyre manufacturing is well within reach, especially as clean power availability continues to expand. For electricity-led operations, increasing the share of renewable energy is already a practical pathway, not a distant target,” he says.

However, execution will hinge on system-level factors. “What will make the difference is how reliably this power can be integrated at scale – through consistent open-access frameworks, stronger grid alignment, and wider use of hybrid solutions that better match continuous industrial demand,” Jain says.

The trajectory is clear: renewable energy in tyre manufacturing is transitioning from opportunistic adoption to structural integration. For developers such as CleanMax, the challenge – and opportunity – lies in engineering solutions that convert intermittent resources into dependable industrial infrastructure.

Wallace Instruments Launches WAS3 Pneumatic Cutting Press To Enhance Specimen Precision And Safety

Wallace Instruments, a globally recognised leader in rubber testing equipment, has expanded its United Kingdom-manufactured specimen preparation lineup with the launch of the WAS3 Pneumatic Cutting Press. The new device joins the company’s range of rubber testing equipment.

Unlike manual cutting methods, pneumatic systems apply consistent force on every cycle, eliminating operator fatigue and variability. Poorly prepared specimens with uneven edges or internal stress can compromise test accuracy, while the pneumatic approach also reduces repetitive physical strain, supporting technician wellbeing during long production runs.

The WAS3 prioritises safe single-operator use through a two-button activation system requiring both buttons to be pressed within half a second, preventing any hand contact with the cutting area. Additional three-sided protective guards further enhance operational safety.

Delivering 15 kN of cutting force, the press easily cuts through 10-mm thick, 95 Shore A rubber sheet using five bar of filtered air pressure. It works with existing Wallace cutting dies, so laboratories can integrate the unit without replacing current tooling, and its compact footprint suits both lab and production environments.

Chris Norval, Managing Director, Wallace Instruments, said, "Specimen preparation is the foundation of accurate rubber testing. With the WAS3, we focused on practical safety, dependable cutting performance and drop-in compatibility. Labs get a compact pneumatic press that fits the air lines already in place, uses their current Wallace dies and delivers consistent results for every operator – because when specimen quality is controlled, you can have confidence in the results that follow."

DUNLOP And Fujitsu Slash Tyre Analysis Time By 90 Percent With New AI Surrogate Model

DUNLOP (company name: Sumitomo Rubber Industries, Ltd.) has teamed up with Fujitsu Limited to create an artificial intelligence (AI) surrogate model that predicts tyre performance rapidly and with high precision. The breakthrough was validated in a proof of concept tied to DUNLOP’s digital transformation strategy. When applied to tyre deformation upon road contact, the technology slashed analysis time by 90 percent, from 45 minutes to just 5 minutes while processing nearly 600,000 mesh elements.

Based on these results, both firms will build a design support tool, aiming for deployment at DUNLOP by April 2027. The system runs on FUJITSU MONAKA, a next-generation energy efficient Arm-based CPU.

Tyre design typically relies on finite element method (FEM) analysis, where finer mesh grids boost accuracy but increase calculation time and costs. To tackle this, the partners developed an AI surrogate model that solves FEM equations using past data. The model, based on the Graph Neural Network algorithm, predicted contact shape with 87.7 percent accuracy, enabling faster decisions and lower costs.

Select findings will be shared at the 31st Computational Engineering Conference starting 3 June 2026. By December 2026, both companies will test the model on a FUJITSU MONAKA prototype to refine speed and power use.

Under its long-term strategy R.I.S.E. 2035, DUNLOP seeks to provide new experiential value from rubber. Through this co creation, the tyre maker will enhance its analytical technologies and strengthen innovation. Fujitsu will promote this approach across large scale FEM analysis in automotive and other manufacturing sectors, contributing to carbon neutrality via an AI platform combining FUJITSU MONAKA and GNN.
