Evonik, one of the world leaders in speciality chemicals, is developing a new process that could make more recycled rubber useable for new tyres.

Because of its chemical structure, recycled rubber has been very limited in its suitability for use in new tyres. However, Evonik's research team has made significant progress with a new process that may allow for the use of up to four times as much recycled rubber in new tyres as previously possible. The development project by Evonik additionally bolsters the tyre manufacturers' extensive sustainability endeavours.

Normal production of new tyre rubber involves vulcanising raw rubber, sulphur and other ingredients. Applying pressure and heat causes the sulphur to link with the rubber's long carbon chains, creating a strong, three-dimensional network. That is also how tyre rubber from tyres nearing their end of life is structured. Nevertheless, the material's characteristics are different from non-vulcanised rubber because it has previously undergone vulcanisation. Currently, the top limit imposed by trade associations in the tyre recycling industry is an admixture of roughly five percent ground tyre rubber from end-of-life tyres. As a result, only a small proportion of recycled rubber powder is currently employed again in the production of new tyres. Furthermore, a lot of tyres nearing their end of life are still thermally reprocessed to be used as fuel for energy production. However, Evonik’s research team has now succeeded in reversing the vulcanisation of rubber to a large extent.

Christian Mani, Project Manager – Circularity, Evonik, said, “That brings us much closer to the key targets of sustainability and resource efficiency in this sector. Rubber is far too valuable a raw material to be used only once in tyres. We want to incorporate it into a circular system. By adding a special formulation containing vinyl silanes, the firm bonds in the recycled rubber can be split. We cleave the sulphur bridges in the rubber, yet leave as many of the long carbon chains as possible untouched.”

These vinyl silanes have already been successfully used for devulcanisation by the study team. In contrast to the above-mentioned technical criterion of about five percent, the percentage of recycle in the rubber blend could be increased to as much as 20 percent in testing. With test series and trials, Evonik is currently moving towards the next significant goals. Finding a solution that clients may use to industrial production in the near future is the goal. "Ultimately, our approach must prove convincing on a large, commercial scale,” added Mani.

Designed to tackle the largest truck and bus wheels while maintaining precision for passenger vehicles, the RB30T Hybrid Wheel Balancer from Ranger (a BendPak division) delivers power and versatility. Switching between heavy-duty and light-duty applications is effortless, requiring just a button press. Its integrated pneumatic wheel lift enhances safety and ergonomics by minimising manual handling and reducing injury risks.

Capable of balancing wheels for buses, semi-trucks, OTR vehicles, light trucks and cars, the RB30T ensures fast, accurate results without recalibration. Its re-engineered platform supports wheels up to 330 lbs (approx. 150 kg), 49.25 inches in diameter and 20 inches wide, with rapid cycle times – seven seconds for car wheels and around 20 seconds for full truck assemblies. At its core, the Ranger Drive-Check system uses advanced 64-bit processing and quartz piezoelectric sensors to detect even the slightest imbalances across multiple axes. This smart technology simulates real-world driving conditions, identifying vibrations before they become road issues and automatically recommending optimal corrections.

Built for durability, the RB30T features a ribbed nylon-fibre drive belt, counter-weighted flywheel system and a three-phase motor with solid-state phase conversion for smooth, high-torque operation under heavy loads. The balancer comes ready to use with a commercial mounting kit, including cones and adapters, while its spacious top tray and side shelves keep wheel weights and tools organised for efficient workflow.

Available as a standalone unit or with the Ranger Select package – which includes professional installation and training – the RB30T is a robust solution for shops handling diverse wheel balancing needs.

Sean Price, Director of Product Development, said, “The new RB30T wheel balancer can do it all. Its versatility makes the RB30T a great choice not just for heavy-duty fleets and repair garages but also for high-volume tyre shops and mixed fleets.”

Bridgestone has officially rolled out its proprietary aircraft tyre management system “easytrack” in collaboration with Cebu Pacific Air, marking the first deployment of the solution by a commercial airline.

The system, launched in April 2025, uses QR codes and a smartphone app to track aircraft tyres across the supply chain—replacing Cebu Pacific’s manual, paper-based process.

“As Cebu Pacific continues to expand its operations, it's essential that we invest in smart solutions that enhance efficiency and reduce manual workload,” said Shevantha Weerasekera, Vice President, Engineering & Fleet Management at Cebu Pacific. “Partnering with Bridgestone to implement the ‘easytrack’ system has enabled us to significantly improve our tyre  management processes significantly, ensuring greater accuracy, safety, and productivity across our operations.”

Bridgestone said the system has halved labour time for inventory management and achieved full tyre tracking accuracy after verification trials at Cebu Pacific’s warehouses, MROs, and maintenance bases.

“As a value co-creation partner, we have proposed solutions tailored to on-site operations based on learnings and insights gained from Cebu Pacific Air’s frontline operations,” said Arata Tomita, Director, Global Aviation Tire Solutions Business Division at Bridgestone. “We are very pleased that the official implementation of ‘easytrack’ has contributed to the improvement of operational accuracy, safety, and productivity.”

Bridgestone said the move aligns with its “Bridgestone E8 Commitment,” with a focus on enhancing efficiency and ecology by supporting sustainable tyre practices and operational productivity.

Japanese start-up ispace inc. and tyre maker Bridgestone have agreed to jointly develop tyres for small and midsize lunar rovers, targeting Moon use by 2029.

The partnership equips Bridgestone’s elastic wheel technology—designed to adapt to harsh lunar terrain—on ispace's rover prototypes. The companies will conduct Earth-based performance tests before Moon deployment.

“Bridgestone’s lunar rover tyre has a structure of thin metal spokes, enabling flexible deformation while maintaining durability,” said Masaki Ota, Director of OE Business Strategy & Planning/New Mobility Business Division at Bridgestone. “This design delivers superior ability to traverse and shock absorption, allowing the rover to traverse the lunar surface and overcome obstacles such as lunar rocks.”

Bridgestone started developing lunar rover tyres in 2019 and unveiled concept models in April 2025 with lower weight to suit smaller rover platforms.

ispace, known for micro-sized lunar rovers, sees the partnership as key to its long-term lunar economy mission.

“ispace's goal of establishing a new economy on the Moon requires the participation of players from a wide range of industries,” said Takeshi Hakamada, Founder & CEO of ispace. “Bridgestone… is now developing lunar rover tyres for the extreme environments found on the Moon. These tyres will undoubtedly contribute to future human advancement on the Moon.”

The companies said they are also exploring collaboration opportunities through the Space Strategy Fund at Japan’s national space agency, JAXA.
