The Tyre Pressure Monitoring System (TPMS) tech, despite its huge safety benefit, is still seen as a premium feature in most mass-market passenger vehicle segment and two-wheelers in India. Aurangabad-based component supplier Varroc’s Indirect TPMS with over 90 percent accuracy aims to make smart inroads. Tier 1 automotive supplier Varroc is looking to harness the data from GPS sensor and Anti-Lock Braking System (ABS) sensors to provide tyre pressure information to two-wheelers and four-wheelers. 

The company is looking to make smart gains through Indirect Tyre Pressure Monitoring Systems (ITPMS), which rely on existing sensors in a vehicle to generate the information without compromising on quality and time-lag.

Fritz Abraham, Chief Technology Officer, Varroc, told Tyre Trends that “the direct TPMS uses pressure sensors at the air inlet of each tyre and communicates the information to the vehicle dashboard using wireless communication or through complex harness. This is not only expensive but also require heavy maintenance. If there exists a solution that can use the existing sensors and provide the information of tyre pressure, it is the ‘Indirect/Intelligent Tyre Pressure Monitoring System’. This system provides information of the tyre pressure without the need of a pressure sensor.”

The radius of the tyre changes with respect to air pressure and hence the linear displacement per one rotation of tyre changes with respect to the pressure. The linear displacement can also be measured using GPS by calculating the rotational speed of the wheel and radius of the tyre.

The ITPMS solution simply put is a software stack that can be integrated with Varroc’s cluster and telematics solutions. The machine learning (ML) software analyses various parameters set by the company to provide tyre pressure reading to the user. Since it does not require any additional TPMS hardware, it is substantially cheaper compared to solutions using battery-based sensors.

“The ITPMS exploits the deviations in linear displacement with respect to wheel rotations and predicts the tyre pressure. This relation is not straightforward; it is a complex method to derive the mathematical equations. Hence, ML techniques are used to quantify the relation,” said Abraham.

The ITPMS primarily requires a GPS sensor (telematics data) and ABS, which is integrated during the vehicle assembly level. Varroc states that OEMs will be able to provide access to the tyre pressure on any HMI (Human-Machine Interface) device like the vehicle instrument cluster, vehicle telematics and connectivity app, among others, to easily provide the information of the tyre pressure.

Varroc had initially initiated the development of the ITPMS specifically for two-wheeler applications. The company mounted a GPS device on a two-wheeler equipped with ABS. It collected the data during vehicle operation across varied scenarios, including differing tyre pressures, diverse road conditions and various weather conditions such as sunny and rainy days.

“This data was then post-processed and analysed using data science and machine learning techniques to develop a model that accurately captures the relationship between tyre pressure, wheel speed and the speed as measured by the GPS. This model forms the foundation for understanding and monitoring tyre pressure indirectly using available data points from the vehicle’s operation,” he shared.

Demand scenario for TPMS

It is no secret that while TPMS technology has been around for more than a couple of decades, its adoption in India still remains a very small percentage. In India, most TPMS solutions available in the OE as well as aftermarket are Direct TPMS.

They are said to have their own set of challenges, such as its reliability due to varying temperatures, environmental and climatic conditions. Then there are the challenges associated with wireless communications. Sensor battery issues and cost too are deterrent factors.

On the other hand, the small percentage of vehicles that utilise existing ITPMS categorise the tyre pressure in broad classifications (low pressure or high pressure). They do not provide precise measurements, which limits their adoption and effectiveness in ensuring optimal tyre performance and safety.

However, Varroc already has developed the ITPMS to provide basic information (low or high); now it is in advanced stages of development to provide precise tyre pressure information with over 90 percent accuracy.  While the company has been tight-lipped about the introduction of the solution in the market, Varroc is said to be in discussions with its clients to bring it to the market soon.

Abraham further shared, “The primary reason for the limited adoption of TPMS is cost. Premium segment vehicles often include TPMS as a standard feature due to the higher price range, making it more feasible to absorb the associated costs. In contrast, aftermarket TPMS solutions are generally expensive and demand ongoing maintenance, which can be a deterrent for many vehicle owners.  Additionally, there is a general lack of awareness regarding the importance of maintaining optimal tyre pressure. Many drivers may not fully understand the safety, performance and fuel efficiency benefits of consistent tyre pressure monitoring, further impacting the adoption rate of TPMS systems.”

As per the company, the ITPMS comes with self-learning feature and is designed with 80 percent cold tyre pressure threshold and tested per AIS 154. The threshold can be further optimised and customised as per the requirement of the customer.

As vehicle emissions regulations evolve, the lack of global uniformity is becoming a growing concern for OEMs and tyre manufacturers. With disparate standards across regions, companies are forced to navigate a complex regulatory maze, straining research and development and production resources. The shift towards electric mobility coupled with heightened focus on non-tailpipe emissions, such as tyre and brake abrasion, further amplifies the need for harmonised frameworks. Industry leaders including Audi’s Sebastian Gramstat argue that collaboration across borders and sectors is essential not just for compliance but for meaningful progress in sustainability and innovation.

Tyre regulations are rules and standards established to ensure that tyres used on vehicles meet safety, environmental and performance criteria. The impetus on new and updated regulations is also growing across regions to reduce pollution brought about by tyre abrasion, rolling noise etc.

The ECE R30, ECE R117, EU Tyre Labelling Regulation (2020/740), which is implemented within the European countries, or JIS Standards of Japan, CCC Certification of China, AIS 142 and BIS Certification of India and FMVSS, DOT Code and UTQG of the United States are different region-specific regulations aiming for a same outcome.

But the vastness of these regulations poses as a challenge for automobile OEMs and tyre makers alike as a lot of energy and resources have to be diverted within production and research and development lines to meet these standards.

Furthermore, the advancement of electric mobility and changes in vehicle dynamics are also slated to impose new regulations worldwide. Hence, the need for a uniform regulation has become a precondition.

Speaking to Tyre Trends on the need for uniform regulations, Dr Sebastian Gramstat, Senior Expert Development Brake System, Audi AG, averred, “Our company delivers products globally and having a unified standard is far more efficient than navigating a patchwork of regional requirements and regulations. Harmonisation brings clear operational and strategic advantages. That’s why we actively support and participate in standardisation and harmonisation working groups.”

“The European Union is involved through bodies such as the Joint Research Centre (JRC), but we also recognise the unique demands of other markets, particularly the US, where customer expectations can diverge significantly. These are often beyond the immediate scope of EU regulators. Our role is to help connect these dots by facilitating dialogue, sharing insights and contributing to building a global standard that benefits the entire ecosystem. We believe this collaborative approach is not only useful but essential to moving the industry forward,” he added.

The need for uniformity is exacerbated as OEMs and tyre makers continuously amp up research and development efforts to curb noise and air pollution from tyres. “Noise pollution, particulate matter or overall tyre wear remains a challenge. And the first step to tackle it is collaboration to develop a standardised method for accurately measuring tyre abrasion and wear. We are also working on such collaborations. Without reliable quantification, you can’t evaluate whether any mitigation measure is actually effective,” said Dr Gramstat.

He added, “This method needs to be robust, applicable across a wide range of real-world scenarios and globally accepted. That’s why we’re collaborating not only with industry partners and academia but also with regulatory authorities. This effort is taking place under the auspices of the United Nations and involves close coordination with national bodies, ministries and the European Commission. The goal is to ensure that the methodology we develop isn’t just technically sound but also internationally harmonised with Euro 7 regulations and integrated into UN regulations so it can be implemented consistently across Europe, North America, Asia and beyond.”

THE EURO 7

Tyres are a crucial component of overall vehicle design to the extent that many OEMs have dedicated in-house departments focused solely on tyre development, including Audi AG. While tyres aren’t developed in isolation, the process involves close collaboration with manufacturers to meet specific, often bespoke, requirements. These custom specifications ensure the tyre aligns with the car’s performance targets and regulatory demands including type approval.

When selecting a tyre, OEMs weigh multiple parameters; safety, performance and comfort are chief among them. But increasingly, attention is also given to sustainability and economy. Factors like tyre abrasion, longevity and fuel efficiency are becoming just as critical, particularly as regulatory frameworks begin to formalise such requirements.

Ultimately, the process involves balancing trade-offs. As Dr Gramstat put it, no tyre can deliver 100 percent on every metric. The goal is to find the best possible compromise – one that supports a premium product and meets both regulatory standards and consumer expectations.

Euro 7 is the upcoming EU vehicle emissions regulation set to take effect from 2025 for cars and vans and 2027 for trucks and buses. It introduces stricter limits on nitrogen oxides, carbon monoxide and particulate emissions, covering both combustion and electric vehicles.

It also regulates brake and tyre emissions and requires compliance under real driving conditions. It aims to cut air pollution, support the European Green Deal and standardise emission rules across vehicle types.

Alluding to whether the industry is ready to adopt the regulation, Dr Gramstat noted, “The industry is well-positioned for adoption. The European Tyre and Rim Technical Organisation (ETRTO) plays a central role in coordinating the efforts of tyre manufacturers across the continent, including legacy European brands and Asian manufacturers, with research and development and production facilities in Europe. Beyond Europe, we’re seeing strong international engagement. U.S. Tire Manufacturers Association (USTMA) is actively involved, and on the global standards side, ISO is working in parallel to develop the necessary technical frameworks. Stakeholders from China are also contributing significantly. This is no longer just a regional conversation but a truly global initiative. Experts from continents are collaborating to align regulatory, technical and industrial priorities, ensuring the tyre industry is prepared to meet the evolving demands of Euro 7 and beyond.”

Further outlining the impact of the regulation, he said, “Tyre manufacturers have largely operated under internal benchmarks for metrics like mileage and abrasion till date. Euro 7 represents a shift towards formal regulation, creating a harmonised framework that applies to the entire industry. This will undoubtedly influence existing design priorities. There’s a complex interplay between various tyre performance criteria such as wet grip, rolling resistance, noise and abrasion. Regulatory limits on one can impact the others, so the challenge will be to minimise trade-offs while maintaining overall performance. At this stage, it’s difficult to offer a one-size-fits-all answer. The impact will vary depending on vehicle type.”

REPLACEMENTS

Premium automobile OEMs like Audi have been using tyres from premium European tyre makers for decades. But as the status of Asian manufacturers changes, there might be room for such companies within the supply chain of premium car makers.

“At the end of the day, it’s not about the brand label but meeting the technical and performance specifications we define. Whether a supplier operates in the premium or high-volume segment, what matters is its ability to fulfil our requirements. If a manufacturer can meet those benchmarks and is willing to collaborate and co-develop with us, then they’re absolutely welcome. Competition in the supplier landscape is a positive force. It drives innovation, efficiency and ultimately better outcomes for the end consumer. We believe valuable ideas can come from any corner of the market and we’re open to partners who share our commitment to quality, performance and progress,” said Dr Gramstat.

He also acknowledged that there is a growing trend within the company to include tyres made from renewable and recycled materials. “The move towards sustainable materials is more than a marketing exercise. It’s becoming embedded in product development strategies across the industry. We’re already seeing recycled content being integrated into certain product lines, and the ambition from suppliers to scale this up is very real. What’s encouraging is that this isn’t limited to one-off pilot products. There’s genuine momentum towards making sustainability a core part of tyre manufacturing. For us, this aligns with our broader sustainability goals, and we see it as a critical area of innovation moving forward,” said Dr Gramstat.

However, the executive emphasised the importance of maintaining a balance too. According to him, sustainability is just one of several key factors in vehicle design while others include safety, comfort, performance and cost. He stressed that no single aspect, including sustainability, could come at the expense of another.

To meet these multi-dimensional goals, additional research and development efforts are required to create a product that meets safety and performance standards while also addressing environmental concerns. Economy remains a consideration as well. Internal research conducted under a European-funded project suggested that customers are, in fact, willing to pay a premium for more sustainable products but only up to a point. Price sensitivity remains a limiting factor.

Turning towards next-generation tyre concepts such as airless tyres, Dr Gramstat noted that innovative ideas like this were once viewed as distant possibilities but are now gaining traction. He cited the LEON-TI project from four years ago, in which airless tyre prototypes were first explored. Since then, similar concepts have been tested by various companies, including in pilot programmes for commercial delivery fleets in Asia.

Although these innovations show promise, particularly for reducing noise emissions and improving durability, they are still in advanced development stages.

THE FUTURE IS CHANGING

As the automotive industry moves towards electrification, the conversation around ‘zero-emission’ vehicles is evolving. Dr Gramstat acknowledged that while electric vehicles eliminate tailpipe emissions, other sources of pollution such as brake and tyre abrasion remain unaddressed in regulatory terms.

Currently, there are no standardised methods for measuring particulate emissions from these sources, but the industry is actively working on it. According to the executive, regulatory bodies and stakeholders are collaborating to develop measurement frameworks. Once these standards are in place, automakers will be able to quantify non-tailpipe emissions and provide a more accurate assessment of a vehicle’s overall environmental footprint.

The executive stressed that collaboration across the value chain is essential, especially between vehicle manufacturers and tyre companies. Such partnerships already exist within serial and advanced development efforts, including participation in the United Nations’ GRBP task force, which brings together manufacturers, tyre associations and regulators to advance tyre abrasion standards.

Weight reduction remains another key challenge. Automakers continue to look for ways to decrease vehicle mass but face constraints. Safety regulations now require more sensors and electronic control units (ECUs), which cumulatively increase vehicle weight. Although each component adds little individually, the growing number of sensors and accompanying wiring has a significant cumulative impact.

As for tyre development, the question of smart tyre was also addressed. While such technology offers valuable insights during research and development phases, Dr Gramstat expressed scepticism about its near-term viability for mass-market vehicles.

In a major step toward sustainable waste management, RPM Automotive Group has partnered with Fornnax to enhance its tyre recycling capabilities in Australia.

As part of the initiative, RPM has integrated Fornnax’s high-capacity SR-200 HD primary shredder into its operations, significantly improving recycling efficiency and material quality.

The collaboration supports RPM’s broader environmental goals and positions the company to process over 180 tonnes of used tyres weekly, with plans to scale beyond 300 tonnes. The move is expected to help RPM capture up to 5 percent of Australia’s national market share in tyre recycling.

Jignesh Kundaria, Director and CEO, Fornnax, said, "At Fornnax, we understand the urgency of addressing end-of-life tyre waste, not just in Australia but globally. The SR-200 HD Primary Shredder is designed for exceptional efficiency, enabling RPM to process vast quantities of discarded tyres while maintaining optimal operational performance. This collaboration showcases our dedication to providing our clients with the robust, high-performance solutions they need to excel in the circular economy."

RPM’s 3,500 sqmt facility not only boosts recycling output but also transforms waste tyres into rubber-based materials for road projects and industrial fuel. Leveraging its distribution network, the company aims to recycle up to 54,000 tonnes of tyres over five years.

The initiative aligns with Australia’s 2021 ban on tyre waste exports and underscores the urgent need for local recycling solutions.
