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.

Hankook Tire, the exclusive tyre supplier for the ABB FIA Formula E World Championship, played a central role in the season’s pivotal Japanese double-header. As the official race tyre for all competitors, the company’s iON Race compound was put to the test under extreme and shifting conditions during Rounds 14 and 15 of Season 12 at the 2026 TDK Tokyo E-Prix.

The weekend’s on-track action produced two dramatic winners. CUPRA KIRO’s Dan Ticktum snatched victory in Round 14 with a last-corner overtake on Jake Dennis, while Nick Cassidy completed the podium. The following day, Mahindra Racing’s Nyck de Vries claimed Round 15, finishing ahead of Cassidy and Dennis, who secured second and third respectively. The entire paddock also observed a period of remembrance for the late Cyril Blais.

The 2.575-kilometre temporary circuit, featuring 18 corners and situated around Tokyo Big Sight, hosted its first-ever night races, drastically altering track conditions from practice to competition. Unstable weather compounded the challenge, with a Sunday thunderstorm cancelling Free Practice 3 and leaving a damp, drying surface for Round 15 that demanded constant adaptation in tyre warm-up and strategy.

Throughout the weekend, Hankook’s iON Race tyre demonstrated reliability across the evolving grip levels and temperature swings. Following the Tokyo results, Dennis retains the championship lead with 146 points, narrowly ahead of Mitch Evans and Pascal Wehrlein. The title battle remains fiercely contested and will be resolved at the season-ending Hankook London E-Prix double-header on 15–16 August.

Manfred Sandbichler, Senior Director, Hankook Motorsport, said, “Bringing Formula E night racing to Tokyo for the first time made this a distinctive weekend and one of the more unusual tyre assignments of our season. The contrast between afternoon running and the 20:05 races shaped how teams prepared for both events, and the iON Race managed that transition and the changing weather conditions well, delivering consistent and predictable performance as the circuit cooled through the evening.”

Tegeta Green Planet recently contributed to the ‘Circular Future’ green camp, an environmental education initiative organised by CENN and funded by the European Union. The camp, which hosted 23 teenagers from the Adjara and Kakheti regions, was designed to deepen ecological understanding, advocate for waste-free systems, and inspire long-term behavioural change among the next generation.

Throughout the week-long gathering, young attendees engaged with forward-thinking methods for minimising refuse, prolonging product life cycles and improving separation and recovery processes. Interactive workshops translated abstract circular economy theories into tangible daily actions, equipping participants with the know-how to conserve materials and shrink their personal environmental toll.

A noteworthy component of the programme occurred on 22 July, when a specialised seminar titled ‘Circular Economy: Waste Reduction and Recycling for Public Health’ was convened. Co-hosted by Tegeta Green Planet, the UNDP and the Waste Management Business Association, the seminar examined the intersection of ecological integrity and human well-being, illustrating how robust recycling systems directly benefit community health outcomes.

Closing the day’s agenda, Tegeta Green Planet’s Director, Shalva Akhvlediani, offered an in-depth look at the Extended Producer Responsibility model currently unfolding in Georgia. He traced the journey of end-of-life vehicle components – from used tyres and spent lubricants to depleted batteries – through collection, transport and reprocessing channels. Akhvlediani also highlighted his organisation’s network of over 350 domestic producers and importers, stressing that youth education remains a cornerstone of their mission. The floor was then opened for a lively exchange, where students posed probing questions, debated local environmental dilemmas and floated their own grassroots suggestions, reinforcing the message that responsible resource use begins with informed individual choices.

Nexen Tire reported second-quarter revenue of KRW 891.3 billion and operating profit of KRW 34.3 billion, as growth in Europe and higher sales of premium products supported performance despite rising costs and geopolitical uncertainty.

Revenue increased 10.8 per cent from a year earlier, driven by demand in key markets, particularly Europe, the company said .

The tyre manufacturer said its strategy of expanding original equipment (OE) supply programmes and diversifying replacement (RE) tyre sales helped support growth amid weaker demand in the automotive market. Sales of 18-inch and larger tyres accounted for 38.8 percent of total sales, up 3.6 percentage points from a year earlier, reflecting a greater focus on premium products.

Profitability came under pressure as higher raw material prices and increased ocean freight rates raised costs. The company also incurred one-off expenses following the final ruling on US anti-dumping duties, which resulted in a higher tariff rate than previously expected.

Europe was the strongest-performing region during the quarter, with revenue reaching KRW 407.2 billion, the first time quarterly sales in the region have exceeded KRW 400 billion.

The company attributed the growth to higher OE sales from its European manufacturing plant, business expansion in the UK, Türkiye and other markets, and improved distribution and logistics following the addition of a finished-goods warehouse at the plant.

In South Korea, demand for electric vehicle (EV) and sport utility vehicle (SUV) tyres remained strong. Nexen Tire said its expanding OE portfolio, which includes the Hyundai IONIQ 6, Kia's EV3 to EV9 models and other domestic electric vehicles, supported higher OE revenue and increased sales of larger-diameter tyres.

The company also said continued growth in rental sales within the replacement market improved its product mix, while its first OE supply agreement with BYD strengthened its position in the global EV market.

Alongside its financial results, Nexen Tire said it had expanded its OE supply during the quarter to electrified models including BYD vehicles and the Hyundai STARIA EV. Supply to premium automotive brands also increased from a year earlier, supported by research and development initiatives, including AI-based performance prediction technologies.

"Despite growing cost pressures from external factors, we have continued to achieve top-line growth on the back of strong sales in key markets," said John Bosco (Hyeon Suk) Kim, CEO of NEXEN TIRE. "With the stable ramp-up of the second-phase expansion at our European plant and the results of our distribution improvements in North America, we expect more tangible improvements in earnings."

Pirelli has officially communicated to all Formula 1 teams the tyre compound selections for the upcoming Dutch, Spanish and Italian Grands Prix. The Italian manufacturer has opted for the medium-range C2, C3 and C4 compounds for the events at Zandvoort and the new Madrid circuit, while the Monza race will see the softest available tyres, the C3, C4 and C5, deployed.

For the Dutch Grand Prix at Zandvoort, Pirelli has confirmed the same compound choice as the previous year. The coastal circuit is defined by its medium and low-speed corners, including two banked turns, which place significant vertical and lateral loads on the tyres and demand high aerodynamic downforce. The track surface itself offers low inherent grip, a challenge compounded by sand from the nearby beaches being blown onto the asphalt, further affecting tyre performance.

The Italian Grand Prix at Monza presents a contrasting challenge, with its recently resurfaced track encouraging teams to run low-downforce configurations. The pit lane loss time for a tyre change is among the highest of the season, incentivising teams to extend stints and manage degradation to achieve a one-stop race. However, the potential for high ambient temperatures could complicate this strategy, making tyre management more difficult.

Making its debut on the calendar as the Spanish Grand Prix, the semi-permanent street circuit in Madrid features 22 highly varied corners, significant elevation changes and the longest banked turn in the championship. Simulations indicate that the loads on the tyres are comparable to those at Silverstone and Spa-Francorchamps. Consequently, Pirelli’s selection of the medium-range compounds is designed to favour a two-stop strategy and offer greater protection against overheating, a risk to which the softer C5 compound would be particularly vulnerable in warm conditions.
