RFID makes it easier and more efficient to track and perform regular tyre maintenance. It identifies potential problems or failures before they cause a breakdown. Confidex has come out with a tyre tag, smaller than its peers and with an omni directional antenna

As the global tyre industry is witnessing rapid changes in manufacturing, distribution and usage to end of life of tyres, Radio Frequency  Identification (RFID) will play a significant role in tackling many challenges posed by the growing complexity in the sector.

Demand for data collection is growing, calling for intelligent decisions and fast actions. Data on tyres helps tyre companies to improve their production efficiency, reduce rejections and even help in addressing in legal disputes, while fleet companies can manage lifecycle of tyres and operations cost.

In February this year, Confidex, a leading designer and supplier of short-range wireless identification solutions, launched the new Confidex tyre tag, which is designed for tyre traceability through the lifecycle of tyres. The tags are based on RAIN RFID/EPC global Gen2v2 RFID technology, which has global certification for passive RFID tag.

Highlights

The highlight of the Confidex tyre tag is that it is smaller than its peers and has an omni-directional antenna. “Initially, we had enquiries from two Chinese tyre manufacturers - Jiangsu General Science Technology Co and Hodo Tyres. They were looking for solutions for an embedded tyre tag technology that is different from all the other solutions available in the markets. We took two years to design, develop, and release this embedded tyre tags commercially. Our RFID tag is a bit smaller than the existing tags available in the market, having an Omni directional antenna.

Now these two Chinese companies are ready to release the mini truck tyres with our embedded RFID tags,” said Paul Broekhuizen, Executive Vice President Smart Industries at Confidex Ltd. By integrating RFID tags within the tyre during the manufacturing process, fleet operators and other end users can track tyre wear and usage. This can help to control ongoing tyre costs. RFID makes it easier and more efficient
to track and perform regular tyre maintenance, as well as identify potential problems or failures before they cause breakdown, says the company.

According to the company, its tyre tag can be fitted with a flexible position within the tyre and is 40 mm smaller than other comparable tags on the market. Its omni directional antenna provides greater flexibility for both warehouse and yard management applications. The Confidex tags offer a read range up to 3 metres or 9 feet from all directions and are compliant with the ISO 20909 and ISO 20910 standards. “The main advantage that the omni directional RFID tags provide is that you can take readings from any direction by a handled reader. You can even have a fixed reading tool in your workshop, and you need to take your vehicle near to or pass by the reader. The ratings are accurately taken. That was the key requirement of the Chinese customers too,” said Broekhuizen.

Confidex is also in discussions with major European tyre companies to test its tyre tags. Positioning Tyres come with different designs and materials, compositions and thickness, so the challenge is to fit an
RFID tag at an ideal position. Since the Confidex tyre tag is installed before the vulcanisation process, it can be placed in any position. “Customer can embed a tag at any position. But, better to check with Confidex, we can simulate how it performs in the new position,” Broekhuizen pointed out. Since the Confidex RFID tag is smaller in size compared to the other tags available in the market, with minor changes,
it can be easily fitted in the tyres that have already been into production. During the vulcanisation process, tags o through very high heat and pressure for hours and sometimes, the antenna may get damaged.

The Confidex tyre tag has a spring type of the antenna - not a typical 3D spring, but more like flexible folded wire antenna, which is 2D structure. This is more flexible and provides benefits during the vulcanisation. “Due to the spring-like design, air bubbles cannot form around the antenna, making it more flexible and sustainable during bending and stretching in the vulcanisation process,” said Broekhuizen. The tags are IP68 rated against liquids and dust and provide resistance to common chemicals and UV exposure.

The company’s RFID tyre tags have already been tested in-house and now they are being tested by European tyre companies with specific requirements. Since the embedded tyre RFID tags cannot be taken out without damaging the tyre, they are ideal for identifying counterfeit products and lifecycle monitoring. “So basically, an embedded RF ID tag helps to monitor lifecycle of tyres. This is the most ideal and complex RFID tag solution,” added Broekhuizen.

The other solution is the label type of tag, which is used for after-sales solutions. It looks like a simple label, but has an antenna too. These labels have different additives which are meant for the different materials, and the antenna design is based on the materials. Broekhuizen explained: “The rubber and steel of the tyres are very complex substances. There are always chemical reactions when you stick anything on rubber. There are chances of them peeling off and permanently bond, so we need a special kind of adhesive which are best with the rubber composites.”

During the tyre manufacturing processes, RFID labels are applied to different bags or containers of the chemicals and other ingredients. With the help of the labels and the reader on the loader, the mixing process is strictly monitored and controlled.

The third solution is barcoding, which comes with an RFID ag which is for regulatory compliance. The embedded RFID tags also help to monitor the tyres in the recycling business. “Tyres go to different countries, so it is difficult for the recyclers to understand or have data on the lifecycle. With an embedded tag, recyclers can get info on the manufacturers, location, and date of manufacturing and
other info. And with all such info, recyclers can manage their business more efficiently,” said Broekhuizen. The information on the Confidex tyre tags come up with the extended memory so additional information can be stored. “There is always fixed information on the RFID and then there is an EPC memory which can have more information.”

Broekhuizen sees growing demand for embedded RIFD tags in both developed and developing markets for different reasons. According to him, a more substantial challenge is to tackle counterfeit cases in the tyre industry, and such cases can be avoided by using RFID tags. In the developed markets, RFID will help to reduce labour costs and improve efficiency.

The company also plans to explore the penetration of its RFID tags in the OTR segment, where the total cost of ownership and lifecycle are the main drivers of the business. Tyre companies are also exploring tyre leasing business. According to Broekhuizen, huge business opportunities lie before the company as the tyre rental business model needs embedded RFID tags. With the lease model, fleet operators can bring down the operating cost by almost 50%. “Fleet companies have to use as per the usage of the tyres or per kilometre. With RFID tags, all data and monitoring can be done accurately,” he said.

Hana Technologies, Inc. (Hana RFID), a global leader in the design and manufacturing of embeddable RFID tyre tags, has become the first RFID company to join the Circular Rubber Platform. This development aligns with Hana RFID’s mission to drive innovation in tyre traceability and reinforces the company’s long-standing commitment to sustainability and circularity in the tyre and rubber industry.

Hana RFID has been at the forefront of RFID-enabled tyre traceability since 2005, facilitating smooth tracking from cradle to grave and promoting circularity. Hana's RFID tyre tags, which are embedded during manufacturing, provide each tyre a distinct digital identity, facilitating complete lifetime tracking from manufacture and use to recycling and reuse. Hana hopes to promote RFID usage in sustainable tyre lifecycle management by working with leading companies in the sector, which will eventually save waste and increase resource efficiency.

Using radio frequency identification (RFID) technology, an RFID tyre tag is a tiny, embedded device that tracks, monitors and controls tyres. In addition to providing smooth connection with inventory monitoring, fleet management systems and other digital applications, such as the European Digital Product Passport (DPP), these tags produce digital twins of tyres. Hana's RFID solutions empower the whole tyre ecosystem to expedite fleet management, improve inventory control, optimize maintenance, and create creative business models that increase sustainability and efficiency.

Val Peters, VP – Marketing, Hana RFID, said, “We are excited to join the Circular Rubber Platform as the first RFID company in this initiative.

The expansion strengthens TÜV SÜD’s position as a leading provider of independent testing and certification services.

Car charging plugs can now be tested in the lab to assess features like weather resistance, mechanical strength and electrical safety. To guarantee the endurance and durability of charging plugs and other parts, the new lab can also conduct crash testing on them. The inclusion of performance testing for tiny batteries is another significant development. Basic functional analysis will be the main emphasis of these tests at first, but in the second part of the year, comprehensive safety and performance evaluations will be included. Similar to this, power tool testing capabilities have been greatly increased to give manufacturers an even more thorough evaluation of the calibre, robustness and safety of their goods.

The capability to ascertain the biogenic carbon content of materials is an additional highlight of the expansion. These assessments support the implementation of sustainable manufacturing methods by giving businesses evidence of the utilisation of renewable raw resources. In order to make sure that packaging and other materials fulfil the strictest safety regulations and don't leak dangerous compounds into food, the testing infrastructure for materials that come into contact with food has been increased at the same time. It's also important to note the recently added ability to evaluate welding fume filtration systems, which may undergo a thorough performance assessment and will soon be certified.

TÜV SÜD is now able to provide an even greater variety of chemical testing services to make sure that products satisfy the most recent regulatory standards thanks to the expansion of its Frankfurt laboratory. With standardised testing for compounds including PFOS, PFOA, C9-C14 PFCAs, and PFHxS, there is a special emphasis on PFAS analysis. Due to the laboratory's expansion, even more businesses may now make use of its extensive testing knowledge, which includes services related to durability testing, risk assessment and certification for a range of product categories.

Walter Reithmaier, CEO, TÜV SÜD Product Service GmbH, said, “By expanding our laboratory in Frankfurt, we are responding to growing demand for product testing and certification. Our new testing capacities will set new standards in safety, sustainability and performance. We look forward to supporting our customers with state-of-the-art testing technology and professional expertise.”

Chicago-based Koala Technologies (KTL), a leading automotive testing, measurement and evaluation tools provider, has launched Te.Sense Bloom – a breakthrough in non-destructive rapid tyre deflation testing. The company has introduced the base kits starting at USD 20,000.

The solution the company claims is fully compliant with FMVSS 110 and emerging EV stability test standards. The Te.Sense Bloom allows passenger vehicle manufacturers and tyre makers to cost-effectively reuse solutions, thereby optimising test programmes while reducing waste.

Currently, the rapid tyre deflation tests often rely on a vehicle being driven over special roadway cleats at defined speeds. This method sees tyres destructively punctured and destroyed by the cleats, and internal inflation pressure is quickly reduced to atmospheric pressure. At times, these tests aim to ensure that the tyres are safely seated on the wheels post rapid deflation, wile at times it is to evaluate vehicle stability in terms of tyre failure.

The company stated that this tests however require destroying multiple tyres, not only leading to waste but may also corrupt certain vehicle dynamics tests that call for a single, targeted tyre failure.

On the other hand, with Te.Sense Bloom, the industry can use non-destructive controlled, rapid deflation for the selected tyres. Using a controllable central air ejector valve with a volume and a flow capacity that simulates a sudden tyre press loss. While the method sounds simple and frugal, the innovation lies in relation with the turn-key nature of Te.Sense Bloom. Automotive testers and engineers get a repeatable set up method, easy in-car operation and simple connectivity with data acquisition systems. As part of its comprehensive supply to Te.Sense Bloom customers, KTL even offers a wheel setup service to simplify test preparations.

The other advantage of Te.Sense Bloom is that the tyre deflation event can be triggered from inside the vehicle or remotely that further expands test scenario possibilities. It can be used for testing tyre inflation pressures up to 100 PSI and speeds up to 140 kmph (87 mph). The real-time tyre inflation data at 100 Hz has a claimed data accuracy of +/-0.1 PSI.  

Kenneth Martin, Head of Tyre Testing at the Transportation Research Center, said, “We have significant experience with rapid tyre deflation tests, using all types of methods, and we’re looking forward to evaluating KTL’s Te.Sense Bloom, since it represents a turn-key, non-destructive solution. There’s definitely some baseline justification for test equipment like this because it fundamentally means consuming fewer tyres. But Te.Sense Bloom’s inherent connectivity opens some other doors also, since triggered and monitored rapid tyre deflations are becoming an area of interest for vehicle stability testing, especially in EV space.” 

The first U.S.-specification kit has been delivered to the Transportation Research Center in Ohio for initial evaluations.

Being compliant with EV stability testing standards the Te.Sense Bloom is already being used by OEMs globally such as Huawei AITO, SAIC Motor Corp and GAC Motor to conduct regulatory tests such as GB/T 38796-2020 (Performance Requirements and Test Methods of Automobile Blow-out Emergency Safety Device).

Mike Lee, Founder and President, KTL, added, “Koala Technologies is excited to introduce Te.Sense Bloom into new markets, beginning in 2025. Bloom has been widely adopted for vehicle development testing in China over the last several years, becoming a must-have tool for many OEMs and key suppliers. It’s one example, among many, of an excellent, trusted, useful automotive testing device that no one knows about outside China. A part of our mission at KTL is to shine a light on some of these exciting technologies that are currently available, but not widely known. Another part of our mission is to help customers achieve their goals more efficiently and at a lower cost. We look forward to the upcoming testing at the Transportation Research Center in Ohio, and we hope that Te.Sense Bloom proves to be a good fit for automotive development programmes in the U.S and beyond.”

Bridgestone Corporation has developed a new Tyre and Road Wear Particles (TRWP) vehicle collection method aimed at understanding the environmental impact of TRWP. The solution was also displayed at the Tire Technology Expo 2025, held in Hannover, Germany, from 4 to 6 March.

TRWP is made up of a blend of road pavement components and tread (tyre surface). In order to comprehend the particle size distribution, dispersion behaviour, and environmental impact – as well as to create effective collecting techniques – Bridgestone is actively engaged in a number of TRWP research projects. The company is dedicated to comprehending TRWP and lowering its generation through these initiatives.

Utilising the B-Mobility testing facility at the Bridgestone Innovation Park in Kodaira, Tokyo, the company has created a state-of-the-art technique that makes it possible to gather TRWP effectively. Bridgestone has used laser light scattering in conjunction with a high-speed camera to visualise the dispersion of particles like TRWP. Based on this, the company has developed a device that effectively catches TRWP and covers the whole tyre. Additionally, the technique made it possible to collect TRWP effectively in a state that removes the effects of exhaust pollutants and broken dust by employing autonomous driving and an electric car with regenerative braking.

Through the Tire Industry Project (TIP), which is part of the World Business Council for Sustainable Development (WBCSD), Bridgestone has been researching the physical and chemical properties of TRWP and their implications on the environment. In addition to the continuous co-creation and internal R&D cooperation, Bridgestone is speeding up its efforts to evaluate TRWP's environmental consequences by collecting it effectively and with a high recovery rate using its recently developed collection technology.
