What is the Role of Smart Tyres in Changing Maintenance, Effectiveness, and Safety?

Use of smart tyre technologies, including embedded sensors, RFID tags, and monitoring of tyre pressure in real-time, is transforming the manner in which modern vehicles are operated, especially in commercial fleets and driverless cars. With the digital transformation of the automotive industry, tyres are no longer a passive element but an active contributor towards ensuring greater levels of safety, optimal use of fuel, and the accurate predictive nature of maintenance. This paper will explore the concept of how these smart systems are redesigning the role of tyres in applications.



Predictive Maintenance: Down-time and Maintenance Cutting

Among the greatest values of smart tyre technology is its ability to aid predictive maintenance. In contrast to the fixed-time preventative maintenance, which is based upon established regular timeframes, predictive systems are based on real time (tyre condition) and, in turn, eliminate service cycles and avoid breakdowns, improving efficiency. Sensors provide real-time feedback to operators about early tread wear, under-inflation, or overheating, all of which are the major causes of roadside failures. Unscheduled downtime can be a major setback to commercial fleets, particularly logistics and public transit. Smart tyre solutions assist in curbing this risk. An example is the ContiConnect system offered by Continental and QuickScan by Michelin, which includes an embedded sensor or a magnetic tread-depth scanner to deliver real-time notifications and long-range performance data to fleet managers. Such systems may interface with more comprehensive fleet management software, which may automatically trigger service requests or part replacements. Companies such as Bridgestone Tyres Blyth are expanding their service provision to include such intelligent systems so that regional fleets can enjoy proactive tyre management with the help of exceptional products and digital tracking. Furthermore, with smart data, tire producers can implement a tyre-as-a-service (TaaS) model in which customers make payments dependent on performance and uptime licensing, not the ownership of the objects. This not only helps to minimize capital expenditure, but it also transfers the burden of maintenance to experts to ensure the optimal utilization of the tyres without micromanagement on the client’s side.

Passive Rubber to Intelligent Systems: The Emergence of Smart Tyres

Historically, tyres were regarded as purely wear-and-tear elements in that they should be removed and replaced manually only occasionally and serviced on a regular basis. Nevertheless, the development of digital integration procedures has given rise to smart tyre systems in which sensors are attached that can be used to transmit data in real time. The parameters that are monitored in these systems are pressure, temperature, tread depth, load, and lateral forces. Sensors and RFID (Radio Frequency Identification) are becoming standard in fleet cars and high-performance autonomous test vehicles. To illustrate, the RFID tags installed during production enable the fleet managers to monitor the entire lifecycle of any tyre (i.e., installation history and maintenance, conditions of use, disposal, etc.). In passenger vehicles, Real-time Pressure Monitoring Systems (TPMS) are already a mandatory requirement in several countries, but in the commercial fleet sector, more capable variants are being used, which do more than just provide an alert on low pressure. They monitor temperatures and any variation in temperatures, as well as detect leaks in the pressure long before it is of safety concern. Monitoring in these situations is especially significant in heavy goods vehicles (HGVs), as such a blowout can result in a serious accident or hold up the traffic. Moreover, when the tyres in hundreds of vehicles are aggregated and analyzed, fleet managers get unprecedented insight into operational efficiency and wear conditions, creating the foundation of intelligent tyre lifecycle management.

Optimization of Fuel Efficiency with Accurate Monitoring

Smart tyres greatly reduce fuel consumption through optimizing inflation levels and rolling resistance. Research indicates that under-inflated tyres by as little as 10 percent may cause a 2 percent reduction in fuel economy. In production cars, this means that extremely expensive fuel is lost as time progresses. Advanced TPMS and temperature sensors allow tyres to self-regulate or inform the driver/operator in case conditions are not normal and maximum efficiency is achieved. Smart tyres are fitted with load sensors and a 3-grip ion detection mechanism, which communicates directly to the central control unit of the vehicle. The torque and braking systems can be adjusted based on this feedback in real time to maximize the range per unit charge and enhance road handling. Moreover, there are efforts in other companies to have adaptive tyres that can vary their contact patch or tread pattern depending on the road conditions and load carried by the vehicle. Such dynamic tyres (though still in early stages) would transform fuel efficiency in autonomous and commercial industries, as they lower drag and maximize both operation efficiency and efficiency over variable routes.

Improved Safety and Self-Driving Car Implementation

Smart tyre innovation is all about safety. On a long-haul truck, as well as on a fully autonomous robo taxi, the loss of one or more tyres can cost not only goods but the lives of human beings as well. Smart tyres Blyth also have the benefit of increasing safety due to their vibration analysis, tread temperature control, and wear profiling to detect any pre-destination failure. Autonomous cars also use smart tyres as the brain's equivalent of feet to give the cars tactile and other environmental information and relay this back to the vehicles with AI. These systems will be able to make split-second decisions based on signals such as sudden grip loss, hydroplaning, or detecting road debris and make contingencies such as rerouting or deploying emergency procedures. Another technology that is already in the testing phase of being able to work alongside vehicle control modules is the Bridgestone Pressure Stat and the Pirelli Cyber Tyre. On subsequent installations, smart tyres may transfer real-time road information through vehicle-to-infrastructure (V2I) communication, alerting other vehicles or the traffic control center of the presence of a danger such as icy sections or potholes.
