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.

India’s tyre sector is moving into a steadier phase after cyclical tailwinds from GST-led formalisation and rural demand. Srikumar Krishnamurthy, Senior Vice-President and Co-Group Head, Corporate Ratings at ICRA, says replacement demand will continue to anchor growth in FY2027 even as original-equipment volumes soften. Premiumisation is lifting tyre makers’ realisations, though input volatility and competition cap pricing power. Export prospects are improving with new trade agreements, but regulatory risks and cost pressures persist as companies balance capex with discipline.

ICRA expects the Indian automotive sector’s wholesale growth to normalise in FY2027. How does this moderation in vehicle volumes translate into tyre demand across OEM and replacement channels?

The normalisation of wholesale volume growth in FY2027 follows a period of elevated growth in the second half of FY2026, which was driven largely by post-GST reform-led factors and favourable rural demand sentiments. The moderation in wholesale volume growth will consequently translate to a similar growth in OE segment. The aftermarket segment, however, will follow the inherent replacement cycle of different sub-segments and other fundamental factors.

Replacement demand currently anchors tyre industry growth. What level of growth do you expect in this segment going forward?

The replacement segment saw a robust growth in the last 4–5 months supported by the post effects of GST rate cuts and healthy rural demand following good monsoons and crop output. The current sentiments are favourable, with factors around economic activities, freight rate movement and farm output reflecting optimistic picture. The segment is likely to outperform the OE segment in FY2027 supported by inherent factors like replacement cycle, safety awareness and regulatory forces.

Premiumisation is evident in vehicles and tyres alike. How is the shift towards larger rim sizes, radialisation and higher-value products shaping revenue growth versus volume growth in FY2026–27?

A change in product mix has been observed in recent times. Rising preference for utility vehicles, premium bikes and electric vehicles have resulted in changes to the average selling price (ASP) of tyre makers. While these elongates the product replacement cycle over time, higher share of sales of large rim sizes and high-performance tyres results in premium pricing and value growth. That said, pricing pressure because of competition and movement in input prices restricts the premium to an extent, in certain segments.

What impact do you expect from the evolving trade agreements between India and United States, along with the proposed India-EU free trade deal, on tariffs for tyres produced and exported from India?

US and Germany are the top-two destinations for Indian tyre exports. Overall, tyre export volumes grew by around 10 percent in FY2025 and around eight percent in H1 FY2026. The recent signing of India-UK and India-EU deals is a positive as Indian tyres are increasingly getting exported to these regions in recent period, reflecting better acceptance. While the developments on India-US tariff-related aspects are a positive, stability in tariff reforms will be critical towards better visibility of exports.

With exporters pivoting towards Europe, Africa and Latin America, what competitive or regulatory barriers might Indian tyre makers face in these markets over the next 12–18 months?

The prospects of Indian exporters remain vulnerable to the regulatory actions and competitive forces. The US tariff-related developments have made tyre makers in

South-East Asia and China more competitive (as compared to India), although the changes in tariff rates is a positive development for Indian exporters. While a depreciating rupee was beneficial, the recent capping of RodTEP benefits is a negative impacting the competitiveness of Indian tyre makers.

Natural rubber prices have remained elevated and volatile. How do you expect raw-material cost trends to evolve in FY2027, and what does this imply for tyre company margins and pricing power?

Rubber prices largely track the demand-supply factors. The prices have largely been volatile in recent years and were affected by a relatively subdued consumption globally. While the supply will remain influenced by weather and other related factors, the global tyre demand is likely to be relatively better, thus keeping the prices firmer in the coming year.

Beyond rubber, inputs such as carbon black and crude-linked derivatives are cyclical as well. Are tyre manufacturers adequately positioned to manage input volatility through sourcing strategies or pass-through mechanisms?

To protect the margins, tyre makers have resorted to better production planning, maintaining optimal inventory and altering the sourcing strategies. That said, the earnings profile of tyre makers remains exposed to any sharp volatilities in input prices, especially replacements.

Industry capex has remained steady, focused on radial capacity and premium segments. Do you foresee a new investment cycle in FY2027–28, or will companies prioritise balance-sheet discipline amid demand normalisation?

The industry’s capex spends are estimated at 8–10 percent of revenues with sizeable investments towards expansions in passenger vehicles and trucks and bus tyres, along with continued focus on debottlenecking, maintenance and R&D activities.

Looking beyond demand and costs, what are the most significant structural challenges facing the Indian tyre sector over the next three to five years – technology shifts, sustainability mandates or global competition?

Multiple trends are emerging in the auto industry, like vehicle premiumisation, changing powertrain mix, fluctuation in adoption of EVs across different product segments etc. In this backdrop, and coupled with global geo-political uncertainties and climate changes, tyre makers face challenges around business strategies. Strengthening technological capabilities, investments in premium performance tyres, enhanced usage of AI for operations, streamlining supply chain activities and diversification are the likely key focus areas for Indian tyre makers.
