As part of its sustainability efforts, Continental aims at using at least ten percent of natural rubber derived from Russian dandelion roots in its tyre and industrial rubber goods production in future.

“We have undertaken a huge research task to meet ten percent of our requirement of natural rubber from dandelion roots. It is a long-term process,” Dr Carla Recker, Head of Expertfield Materials Chemistry & Taraxagum, told Tyre Trends in an interview. “It will take decades to complement natural rubber from Hevea brasiliensis with natural rubber from dandelion plants at an industrialised level. However, the company does not intend to replace NR from Hevea brasiliensis trees.”

According to Dr Carsten Venz, Site Manager at Taraxagum Lab Anklam, “Dandelion will be an additional source of natural rubber, not a replacement to rubber trees, in the coming years.”

Continental has been consequent on the cultivation and processing of Russian dandelion as an alternative source of raw material to the rubber tree in the tropics. Last year, the company officially opened its research and test laboratory named Taraxagum Lab Anklam in Anklam, Germany, a base for its future research into the cultivation and processing of Russian dandelion, within a year after the ground-breaking ceremony held in November 2017.

“The Taraxagum Lab Anklam is the latest key milestone of our project,” said Dr Recker.

The Taraxagum project is crucial for the company. “The natural rubber from dandelion is important to develop a new alternative and sustainable supply of the raw material” Dr Venz said.

On bicycle tyres

Though the lab was opened last year, Continental started working on the dandelion rubber project in 2011, and the company has already used rubber from dandelion roots in its passenger car tyres, truck tyres and industrial rubber goods. “The latest development on production-side is that we have industrialised bicycle tyres with rubber derived from dandelions. So, you can now buy bicycle tyres of Continental made of dandelion rubber in the market,” Dr Recker said. Continental showcased its first bicycle tyre with dandelion rubber at the Tour de France this year.

Currently, the Taraxagum lab is working on dandelion research, and over the next five to ten years, it will focus on the industrialisation of dandelion rubber and increase the share for the dandelion rubber in its products.

“Continental sees the Russian dandelion as one element of our commitment for sustainable natural rubber as detailed in our Sustainable Natural Rubber Sourcing Policy published in October 2018. At least for us, the Russian dandelion is the most promising alternative source for natural rubber. There might be different sources (to get natural rubber), but that does not fit for us. The Russian dandelion can be grown in different climate zones unlike natural rubber from heave brasiliensis trees which need tropical climates to grow. Rubber trees and the Russian dandelion have the same characteristics, the same chemical structure and the same properties. It is just two plants producing the same material,” says Dr Recker. The advantage of dandelion rubber over rubber from trees is that the former has a generation succession of just three months as compared to seven years for the latter.

Since the dandelion plants can be cultivated in Northern and Western Europe, which makes transportation routes to the European production sites much shorter and contributes to the sustainable use of existing resources, thinks Continental.

However, the major challenge will be the 100 percent replacement of rubber made from trees with dandelion rubber. Dr Recker thinks, yes, technically, dandelion can replace tree rubber by 100 percent, but the more significant challenge will be the industrialisation of dandelion rubber to the level of rubber trees. “We are at a research stage. The amount of dandelion available globally is not enough to replace natural rubber commercially. To create that biological system to industrialise the natural rubber from the dandelion will take some time and we will have to be more patient,” says Dr Recker.

Research is a time and capital consuming task. Synthetic rubber is also coming into tyre production in a more significant way, but the crude oil derived commodity has historically been volatile, and even oil-producing nations are diversifying their businesses citing falling productions and growing focus on cleaner options.

Dandelion rubber is not new to the tyre industry; however, the industry does not seem much keen on dandelion plants as an alternative source for natural rubber. “Not everybody (tyre company) is willing to invest in the early research of dandelion rubber and setting up the entire bio-economy. You have to establish a full value chain from breeding to the production of natural rubber from dandelion plants, which is does not exist yet and not every market player is willing to invest in such a long-term process,” explains Dr Recker.

Since Continental sees dandelion a sustaining resource for natural rubber in the future, it has made a substantial investment for the project. It has already poured in 35 million euros for the project. “Though many of our peers are investing in other resources to get natural rubber, I think we are quite unique investing like the way we are to explore alternative resources for natural rubber,” says Dr Venz.

Over 90 percent of natural rubber derives from South East Asia, a tropical region suitable for natural rubber trees. However, erratic climate behaviour is hitting production of natural rubber in this region. Natural rubber producers are also exploring other areas to grow natural rubber trees. According to Dr Recker, the research project has yet to ascertain the survival scope of the Russian dandelion in changing climates. “I believe that Dandelion will grow in all climate zones,” says Dr Recker.

Yield ratio

As of now, Continental also does not have comparable yield ratios between natural rubber from dandelion and hevea brasiliensis. “We are working on determining the output of natural rubber per acre from both resources,” says Dr Venz. “Usually, between 1 and 1.8 ton per hectare per year is produced from rubber trees, and around the same amount of production per hectare we are expecting from dandelion plants,” estimates Dr Recker.

As part of the value chain creation, the company is focusing on breeding for seed production and harvesting, root production and harvesting, and the extraction process. According to the company, growers also need some time to understand and get hands-on to harvest dandelion plants. Every year climate conditions will determine a different impact on the plants. “We will need to see how the crops will react in different climate and harvesting seasons. We are building a network of farmers in North East Germany from whom we learn and whom we can teach what we have learned,” added Dr Recker.

Fundamental design and development of tires for the mobility of the future will be unchanged; however, tires will be expected to be high performance and eco-friendly. According to Continental executives, for the mobility of the future, natural rubber will remain the core ingredient and dandelion will be one of the sustainable options to provide natural rubber. “Rubber be will be used in future to make high-performance tires, and we are exploring the option to have a sustainable source for natural rubber,” adds Dr Recker.

Goodyear takes centre stage at Silverstone this weekend as title sponsor of the Goodyear 4 Hours of Silverstone, the second consecutive year it has headlined the European Le Mans Series event following its return to the calendar last year after a six-year break.

The manufacturer will equip 37 cars across LMGT3, LMP2 and LMP2 Pro/Am with its Racing Eagle tyres. LMGT3 entrants will use the Medium compound, chosen for its adaptability across varying conditions and driving styles, while LMP2 and LMP2 Pro/Am crews run their own Medium specification, a staple of the series since debuting at Le Castellet last season. Wet-weather Racing Eagle tyres remain available should conditions demand.

Silverstone's fast nature is set to shape tactics, with fuel consumption a likely determinant of pit-stop windows. Goodyear anticipates LMGT3 outfits will favour single-stinting to maximise pace on fresh rubber at every stop, whereas LMP2 and LMP2 Pro/Am squads could split between single and double-stinting approaches.

Off-track, Goodyear has arranged several activations. Vector Sport's #10 car ran a special Goodyear Racing livery last weekend at Caffeine & Machine's Warwickshire venue and will race in the same colours. The company also backs Friday's ELMS Charity Run, where Racing Eagle tyre stacks will mark each kilometre and runners finish beneath an inflatable Goodyear arch, with proceeds going to the Luca Guintoli Foundation, supporting families affected by childhood cancer. Goodyear Racing Eagle tyres additionally feature in NASCAR action at World Wide Technology Raceway in Madison, Illinois.

Stephen Bickley, Goodyear Endurance Program Manager, said, “Silverstone should be a fairly straightforward race from a tyre strategy perspective. The high-speed nature of the circuit means fuel consumption will be high, so fuel strategy is likely to be the main factor influencing pit stop timing. The tyre allocations broadly give teams the flexibility to change tyres at every stop, so there is less of a need to stretch a set of tyres purely to save time in a pit stop. We therefore expect teams across both categories to largely focus on single-stinting tyres. The biggest variable at Silverstone is always the weather, which can quickly change stint lengths and pit stop timing.”

The new AZuR CO₂ savings certificate gives commercial vehicle fleet operators a way to quantify and prove the emissions reductions they achieve through smarter tyre strategies. The tool turns calculated savings into transparent, verifiable documentation, allowing businesses to showcase their resource efficiency efforts. The certification sits within AZuR's wider vision of a closed-loop tyre economy, in which quality tyres are kept in service as long as possible through repair, retreading and regrooving, and materials are recovered through proper recycling channels only once further use is ruled out.

Three distinct levers form the basis of the assessment, and fleets may adopt them separately or together. Reusing sound tyre casings through retreading cuts demand for virgin materials and stretches each tyre's service life. Reprofiling technology from Bear-Machines adds as much as a quarter more mileage to compatible commercial tyres, depending on the tyre and how it is used, while simultaneously trimming fuel burn. Digital tyre management powered by CO2OPT analyses a fleet's tyre usage patterns through artificial intelligence, guiding the selection and deployment of suitable tyres; under the right operating conditions, this can shrink fuel consumption and its associated emissions by as much as 10 percent.

Reliability of the reported figures rests on a defined calculation framework applied to each fleet's own data. The retreading portion draws on life cycle assessment work from Fraunhofer UMSICHT, while the remaining measures follow their own established methodologies and fleet-specific inputs. The result is auditable evidence linking implemented tyre management practices to calculated CO₂ reductions.

Beyond emissions figures, the certificate reveals how deeply a fleet has embraced circular practices by showing its share of retreaded tyres. Three tiers structure this indicator: Category A covers fleets above 50 percent, Category B spans 25 to 50 percent and Category C captures 5 to 20 percent. Documented savings and a practical circularity measure are thus combined in a single certification.

Early adopters already illustrate the concept in action. Over a 12-month window, SIS Internationale Speditions GmbH calculated 31.99 tonnes of CO₂ saved through retreading, CO2OPT software and the fuel savings that followed, with retreaded tyres on more than half its vehicles, earning Category A. The Steinkühler Group, meanwhile, reached 44.72 tonnes of calculated savings in the same period using retreading, reprofiling, CO2OPT and resulting fuel reductions, landing in Category C.

Christina Guth, Network Coordinator, Alliance for the Future of Tires (AZuR), said, “Many companies are already investing in lower-emission vehicles and alternative drive systems. However, it is often overlooked that tyres can also make a quantifiable contribution to reducing greenhouse gas emissions. With the AZuR CO₂ savings certificate, we demonstrate how retreading, reprofiling and intelligent tyre optimisation can be combined in a joint tyre management strategy.”

DUNLOP has premiered a new atmospheric short film titled ‘Taking the Line’, which centres on the brand’s participation in the 2026 ADAC RAVENOL Nürburgring 24 Hours. The two-minute production chronicles the journey of the black-and-yellow DUNLOP Porsche 911 GT3 R, car number 17, offering an emotive portrayal of the challenges faced during one of the world’s most gruelling endurance events.

The film, shot over a week at the legendary Nürburgring Nordschleife, employed two dedicated camera crews utilising digital cinema cameras, action cameras, car-to-car tracking and aerial drones to capture the action. The notoriously capricious Eifel mountain weather, with its fog, rain and dramatic lighting, serves as a dynamic backdrop, amplifying the drama and underscoring the circuit’s unique character.

Rather than focusing exclusively on track action, the narrative shifts following the retirement of the DUNLOP car to highlight the essential human element of the race. The production pays tribute to the mechanics, marshals, support crews, drivers and devoted fans, emphasising that the event’s spirit relies on these individuals. This approach also connects to DUNLOP’s deep-rooted heritage in motorsport, blending tradition with innovation since the invention of the pneumatic tyre.

In a notable technical achievement, the filmmakers utilised advanced artificial intelligence to reconstruct a historically accurate sequence depicting the car without using any archive footage. This innovative process, informed by extensive visual documentation and historical references, successfully bridges more than four decades of DUNLOP’s racing history, creating a new and authentic representation of its enduring legacy at the Nürburgring.

Evropi Dionysiadou, Brand Communications Specialist at Dunlop Tyre Europe GmbH and responsible for the production, said, “One of the film’s most memorable moments creates a bridge between the past and the present. As a tribute to DUNLOP’s heritage, a Porsche 962 C appears on the start-finish straight for a few seconds, bearing the same number 17 that raced at the Nürburgring on DUNLOP tyres in 1986 and 1987.”

Dennis Wilstermann, Marketing Manager, Dunlop Tyre Europe GmbH, said, “With ‘Taking the Line’, DUNLOP underlines its deep roots in motorsport. For decades, experience gained in racing has been transferred into the development of road tyres, helping us create products capable of performing in the most demanding conditions and regularly earning recognition in independent tyre tests. An icon of 24-hour racing, DUNLOP has also contributed to 34 victories at Le Mans, a legacy that continues to inspire and drive us today.”
