. Improvements in tread performance, rolling resistance reduction, handling, and durability have been well documented. As vehicles have evolved over the past 20 years, tyres have had to adjust along with them. Larger vehicles, higher performing vehicles, and light-weighting, along with the introduction of electric vehicle technology, are all trends that have steered development over the years.

Through all of it, several key areas in tyre testing have remained steady. Tyres need to meet minimum safety and performance standards as dictated by governments and vehicle OEMs.

•          Tyre durability testing depends on a variety of industry test standards such as endurance testing on a drum.

•          Wet stopping distance, tread wear, and winter traction testing have very specific on-vehicle testing requirements.

•          Rolling resistance testing utilises a couple standardised test methods to measure the amount of hysteretic energy loss from a rolling tyre on a drum and specified surface.

•          Force and moment testing on a moving belt has been used to characterise tyre performance for vehicle design as it relates to cornering and other use conditions.

As time has passed, tyres have been asked to do more and more on vehicles. While the testing methodology has remained similar, conditions have been altered to accommodate these vehicle performance expectations. And while reducing testing time has always been a goal, many of these standard tests still require the same amount of time to conduct.

Because much of tyre testing has been standardised over the years, many facets of the industry can use tyre testing data as a unifying benchmark for evaluating specific performance criteria. For OEMs, the data is valuable to the vehicle development process. For tyre companies, the data is used in a marketing context to compare and contrast features for consumers. Trucking fleets use the data to optimise their operations and reduce costs and fuel consumption. Consistency in testing methodology provides the industry with a unifying foundation of benchmarking data.

That being said, older methods are always being reviewed for obsolescence. For example, NHTSA in the United States is currently considering the removal of test standards for bead unseat and plunger energy testing that were originally developed for bias ply tyre designs.

There are always efforts to look at novel ways of improving the tyre testing process and increasing speed to market. For example, experimenting with different surfaces for drum and belt testing of tyres continues to take place in an attempt to more closely replicate an infinite number of real-life surface conditions. Man-made snow has been developed to extend testing seasons and try to mirror natural snow in an indoor environment. As the industry learns more about how pressure loss impacts rolling resistance and fuel efficiency, more methods have been developed to measure how well different inner liner materials maintain steady tyre pressure. Tyre companies can more readily choose the right materials of construction to suit performance requirements by using material property data from finite element analysis.

Many of these testing methodologies are trending towards virtual testing and modelling of tyre performance. And while tyre modelling has been around since the 1980s, the amount of data and range of data measurement required has increased exponentially.

The key automotive trends driving tyre development going forward continue to be electrification and autonomy. These trends will bring their own challenges to testing and validation. Electrification will present some traditional challenges with new applications, such as managing heavier loads, more aggressive torque / tread wear, reducing noise, and lowering rolling resistance. New materials and constructions are being developed to accommodate these unique challenges for electric vehicles. Tyre tuning will become exceptionally important as second-life tyres are brought into the mix, as consumers will want consistent performance.

From the perspective of autonomous vehicles, sensors and tyre intelligence are being added to provide new data sources for autonomous systems. Tyres equipped with these sensors will have to undergo the same endurance, durability, and performance tests to ensure the sensor can function as designed when faced with the same rigors as the tyre. Depending on where the sensors are mounted in the tyre/wheel assembly, normal tyre dynamics could adversely affect the accuracy of measurements or transmission of data to the vehicle. As aftermarket tires and sensors are developed, testing and validation should follow the same standards to simplify service and compatibility for consumers. Ease of replacement will be critical, as this directly affects the consumer and dealers.

There will continue to be developments and ongoing efforts to improve the fidelity and range of tyre testing data. These improvements will strive to speed up development cycles and improve virtual models going forward. However, the established standards and protocols continue to provide a steadfast and reliable set of tools that development teams, independent evaluators, and testing organisations can use to address new challenges and ensure that the ultimate goal of safety is met for regulatory bodies and consumers.

The Global Data Service Organisation for Tyres and Automotive Components (GDSO) has entered into a Memorandum of Understanding with the RAIN Alliance, a move designed to accelerate the harmonisation of electronic tyre identification and support broader digitalisation throughout the international tyre value chain. This agreement formalises a mutual commitment to advancing interoperable, scalable and globally consistent standards that can be adopted across the sector.

GDSO is responsible for establishing and promoting global data standards for tyres, enabling comprehensive lifecycle applications that serve a diverse group of stakeholders – from manufacturers and logistics providers to fleet managers, recyclers and regulatory bodies. The RAIN Alliance, in parallel, champions the widespread implementation of RAIN RFID technology within a framework that is open, standards-based and interoperable.

The growing importance of electronic tyre identification is underscored by its role in enabling traceability, meeting regulatory requirements, advancing circular economy goals and improving operational performance. Within existing standardisation frameworks, embedded RAIN RFID technology is currently the sole passive data carrier capable of supporting item-level traceability across the full lifespan of a tyre. This partnership seeks to align data standardisation efforts with the underlying identification technologies, thereby reinforcing the ecosystem necessary for reliable and scalable digital identification solutions worldwide.

Although GDSO acknowledges the established position and technical maturity of RAIN RFID, the organisation maintains a technology-agnostic stance. Its primary focus remains on developing robust and adaptable global data standards that foster an inclusive and resilient identification ecosystem. Such an approach supports ongoing innovation and ensures that all actors across the tyre value chain can participate effectively, regardless of future technological shifts.

Through this alliance, GDSO and the RAIN Alliance intend to drive globally aligned standards, enhance system interoperability, support digital use cases throughout the product lifecycle and contribute meaningfully to sustainability and circularity targets. This partnership reflects a shared strategic vision to strengthen the digital infrastructure underpinning the tyre industry.

Riccardo Giovannotti, Secretary General, GDSO, said, “I’m pleased to share that GDSO has signed a collaboration MoU with RAIN Alliance. The collaboration is grounded in a shared commitment to industry-wide standards and to advancing digitalisation across the tyre value chain. As the organisation leading the definition and deployment of global data standards for tyres, GDSO focuses on enabling cradle-to-grave use cases through interoperable and scalable solutions. Within today’s standardisation landscape, the embedded RAIN RFID (i.e. passive RFID) is currently the only data carrier standardised and technically capable of supporting item-level identification across the full tyre lifecycle, which makes this collaboration both relevant and timely.”

A new milestone in agricultural tyre technology has been achieved through the partnership of Titan International, Inc. and Cerebrum Sensor Technologies, Inc. Together, they have unveiled Titan Pressure Perfect (P2), a smart sensor system designed to transform how farm tyres perform and communicate. This system marks the emergence of a broader category known as Intelligent Tyre Solutions (iTS), developed jointly by the two companies.

At the core of Pressure Perfect (P2) is real-time monitoring of tyre pressure, temperature and load. This data enables continuous oversight and works seamlessly with onboard inflation systems, allowing automatic pressure adjustments while the vehicle is in motion. Whether shifting from roadway to field or responding to varying load demands, the system can reduce air pressure by as much as half. This flexibility helps lower soil compaction by up to 35 percent and has been linked to potential corn yield increases of four to six percent.

Pressure Perfect is compatible with all Titan and Goodyear Farm Tyre products and integrates with nearly all inflation management systems already in use. By supporting more precise tyre management, it contributes to longer tyre life, improved machine efficiency and reduced environmental impact through less ground disturbance.

The innovation draws on Cerebrum’s licensed portfolio of patented technologies, including advanced sensors, proprietary algorithms and sophisticated software capabilities. This technical foundation sets a new standard for intelligent tyre management in agriculture. While other industry players focus on replicating existing central tyre inflation and tyre pressure monitoring systems, Titan and Cerebrum are advancing a more comprehensive and forward-looking approach. Pressure Perfect reflects Titan’s longstanding engineering heritage and its continued commitment to leading the field through purposeful collaboration and applied innovation.

Dubbing it the ‘Holy Grail’ of innovations, Scott Sloan, Global Ag & LSW Product Manager for Titan, said, “This is the first system of its kind that delivers dynamic inflation management. Load, tyre pressure and temperature data are gathered by a single tyre-mounted sensor and integrated with tyre-industry load-inflation tables in real time. Imagine bringing together Central Tyre Inflation System (CTIS) and Tyre Pressure Monitoring System (TPMS) technologies, and now they can work together and talk to each other – all without operator intervention."

As urban areas around the world grow increasingly louder, traffic noise has emerged as a critical environmental and public health challenge. Recognised by health authorities as a major risk factor, this pervasive issue extends from European cities to megacities across Asia and Latin America. Continental is addressing this problem by pioneering tyre technologies that significantly reduce rolling noise, thereby contributing to quieter urban environments and enhanced in-vehicle comfort.

The transition to electric mobility has brought tyre noise into sharper focus. With the near-silent operation of electric motors replacing traditional engine sounds, the acoustic contribution from tyres becomes far more prominent, even at moderate city driving speeds. In response, Continental engineers have developed specialised solutions that target noise generation without compromising the safety, durability or performance of the tyre.

One such innovation is the Silent Pattern tread design, featured on models like the EcoContact 7. This technology disrupts the conventional, uniform arrangement of tread blocks that typically creates a rhythmic humming sound on pavement. By intelligently varying the spacing and angles of these blocks, the pattern breaks up this acoustic consistency. Furthermore, it is tuned to cancel out specific sound frequencies, akin to the principle behind noise-cancelling headphones. This results in a measurable reduction of traffic noise at speeds around 50 kmph, where rolling noise is most perceptible to pedestrians and residents.

For reducing noise inside the vehicle cabin, Continental employs its ContiSilent technology. This involves lining the inside of the tyre with a lightweight polyurethane foam that absorbs vibrations caused by the tyre’s contact with the road. By dampening these air vibrations, the technology can cut perceived in-cabin rolling noise by up to nine decibels – a reduction the human ear experiences as nearly halving the volume. This substantial increase in acoustic comfort is integrated into various product lines, including high-performance summer tyres, without affecting driving dynamics or efficiency.

The company’s commitment to low-noise mobility spans multiple vehicle segments. From the Conti Urban NXT for city buses to passenger car tyres like the EcoContact 6 Q and van tyres such as the VanContact A/S Eco, these products are designed to meet stringent noise standards. Consumers can readily identify these quieter options through regulatory labels, like the EU tyre label, which provides clear decibel ratings for external rolling noise. Through these continuous advancements in tread design and sound-dampening materials, Continental is systematically working to diminish the acoustic footprint of road traffic.

According to Achillefs Tsotras, head of Continental’s Tyre-Vehicle Interaction department, “Noise, especially traffic noise from cars, buses and delivery vehicles, is a major burden for people and the environment. With tyre technologies like ContiSilent and innovative tread designs, we are actively reducing rolling noise without compromising safety. This makes every ride noticeably quieter, benefiting drivers, pedestrians, residents and the environment alike.”
