Future of Smart Tyres in India: Safety, Sensors, and Scalability

As the Indian automotive industry accelerates toward connected and autonomous mobility, one critical component often remains under-discussed: tyres. While conversations around vehicle safety frequently focus on Advanced Driver Assistance System (ADAS), road mapping, and vehicle electronics, tyres — the only point of contact between vehicle and road — receive comparatively little attention.

Smart tyres represent a significant evolution in automotive safety and connectivity. They promise real-time data, improved vehicle responsiveness, and better long-term performance monitoring — all crucial for India’s complex driving ecosystem. However, challenges related to sensor integration, battery longevity, algorithm accuracy, and consumer acceptance remain substantial.

In a recent interaction with Acko Drive, Chirag Patel, Senior Manager, FEA/NVH, CEAT Limited, shed light on the development of smart tyres in India, the technical and cost-related challenges involved, and the realistic timeline for mass adoption.

Beyond Rubber: What Makes a Tyre “Smart”?

At its core, a smart tyre is not just a mechanical component — it is an electro-mechanical system. As Patel explained, “In smart tyres we talk about, it is not only mechanical, it is the electro-mechanical part.” This evolution requires integrating sensors and electronic systems into traditional tyre structures.

However, tyre manufacturers alone cannot drive this transformation. “Tyre manufacturers, they are not well versed… technical competency for this sensor development. So, it has to be done jointly first of all,” he noted, emphasising the need for collaboration with third-party technology partners.

The definition of a smart tyre depends largely on the functionality it delivers. A basic example is a tyre equipped with a TPMS sensor. “Someone can say a TPMS sensor, if it is fulfilling the requirement, then it is a smart tyre, because it shows the temperature and the pressure,” Patel said. But the scope extends much further — especially in the context of autonomous vehicles.

Smart Tyres and Autonomous Mobility

For advanced mobility applications, smart tyres must do more than measure pressure and temperature. Autonomous systems demand detailed feedback from the tyre, including acceleration, lateral forces, launch control inputs, vibration transfer, and impact detection.

“Autonomous vehicles must get some of the feedback on the tyre, like acceleration… lateral acceleration, forward acceleration… or the forces also, or impact… vibrations getting transferred to the vehicle,” Patel explained. Such real-time data can help vehicles respond more accurately to changing road conditions — a particularly relevant capability in India’s diverse and unpredictable driving environment.

Missing Link in Vehicle Safety Discussions

While road infrastructure and vehicle electronics are common talking points in safety forums, the tyre’s role often goes unaddressed. The tyre, as Patel emphasized, is nothing but the connecting component between vehicles for a driver input to the road. Steering tuning and vehicle calibration — whether Level 2 or Level 5 autonomy — are performed based on specific tyre characteristics. However, tyre performance changes over time.

Patel questioned whether the same tyre would deliver consistent performance after 20,000 km and again after 40,000 km of use. This is where embedded sensors become critical. Continuous data can help monitor performance degradation and ensure consistent safety standards.

Technical Bottlenecks: Sensors, Batteries, and Algorithms

Despite the promise, implementing sensors inside tyres presents significant engineering challenges. One major issue is battery life. Unlike a vehicle, which has a dedicated power source, a tyre-mounted sensor must operate independently while constantly rotating. “Battery technology should be such a way that a small amount of battery should run for a couple of years,” he explained.

Beyond hardware, algorithm development remains at a nascent stage. While temperature-based failure detection is relatively achievable, more complex handling and wear analysis are still developing. “Handling related aspect, wear related aspect… they are just now at the very beginning stage,” said Patel acknowledging both the ambition and the current limitations of the technology.

Cost: Barrier or Transitional Hurdle?

Cost is often assumed to be a major barrier to smart tyre adoption. However, Patel offered a more nuanced perspective. “Once it is in mass production stage, cost may not be a very big thing,” he said. Initially, manufacturers may charge a premium to recover R&D investments, but large-scale production could significantly reduce price differences between conventional and smart tyres.

He added that functionality, rather than cost, may prove to be the bigger hurdle. In the early stages, consumers willing to pay for enhanced safety may drive adoption. Over time, smart tyres could become a standard requirement rather than a premium upgrade.

Adoption Timeline: Decade to Scale?

So how long before smart tyres become mainstream in India? Patel estimated that meaningful progress will take around five to seven years, while a full-scale adoption is likely to take at least a decade. He drew parallels with ADAS technology, which has been available for years but still faces acceptance challenges in India. 

Pointing out that most consumers who opt for ADAS-equipped cars prefer to switch off the ADAS functions. This behavioral dimension suggests that even if smart tyres become technically viable, consumer trust and adaptation will take time.

Role of Government Support

Given the high development costs and technical complexities, government incentives could accelerate progress. “For a smart tyre… tyre industries are only the responsible partners. But they don’t have a facility for technical know-how, for sensor technology,” he said. Investment is required not only in sensors but also in supporting infrastructure and integration systems. Government backing could reduce financial pressure on manufacturers and encourage innovation, while also aligning with broader national road safety objectives.
