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.

Sun Auto Network is strengthening its presence in North Carolina by consolidating several well-known local businesses under the Sun Auto Tire & Service banner. This integration includes Piedmont Tire, which finished rebranding in late 2025, and four Tire Max locations that made the switch this past March. The process continues with Jackson Auto Worx, while Liberty Tire & Auto is scheduled to follow later in 2026.

To celebrate these changes, Tire Max will host grand opening events over two weekends in April. The first takes place 9 to 11 April at the Madison and Stokesdale stores, followed by the second from 23 to 25 April at the High Point and Summerfield locations.

These community-focused gatherings will feature promotional giveaways such as tyres and a full year of free oil changes, along with other special offers. Through this investment, Sun Auto Network aims to benefit both local drivers and the wider North Carolina communities it now serves.

Michael Loa, Regional Vice President, said, "This is about creating a more unified and recognisable presence across the region. Aligning these stores under the Sun Auto Tire & Service name builds on the strength of our existing network while delivering a more consistent experience for drivers."

Scandinavian Enviro Systems AB (publ) (Enviro) has been informed that Infiniteria Sweden AB and Infiniteria Europe Sàrl plan to ask the Gothenburg District Court to immediately end Enviro’s ongoing company reorganisation. Infiniteria also challenges the legality of Enviro’s recent contract cancellations regarding their joint venture and has indicated it will seek damages as a result.

The reorganisation was originally approved by the same court on 27 February 2026. Infiniteria now argues that the process should be halted at once because its intended purpose is unlikely to be achieved and because continuing would be unfair to Infiniteria. Furthermore, Infiniteria has made clear it will oppose any reorganisation plan that Enviro might put forward.

Infiniteria disputes the validity of Enviro’s termination of their joint venture agreements, which occurred on 20 March 2026 under the Swedish Company Reorganization Act. While no formal damages claim has been filed yet, Infiniteria preliminarily estimates potential claims from the terminations at roughly EUR 84 million. This estimate partially overlaps with an existing arbitration claim against Enviro that was disclosed on 6 February 2026.

Enviro firmly rejects Infiniteria’s stance, asserting that its conclusions rest on incomplete and incorrect information, making them unfounded. Together with its legal advisors and the court-appointed administrator, Enviro is reviewing the matter and will respond to Infiniteria’s claims as directed by the District Court.

Flat tyre protection specialist Tyron Runflat has joined the UK Towing Safety Alliance (UKTSA), strengthening efforts to raise safety standards for drivers who tow caravans, trailers, horseboxes and commercial loads across Britain.

Formed in May 2025, the Alliance is a national coalition convened by the Parliamentary Advisory Council for Transport Safety. It was created after the disbandment of the Trailer and Towing Safety All Party Parliamentary Group, driven by findings from the Driver and Vehicle Standards Agency. Nearly half of non‑caravan trailers inspected were non‑compliant, with many prohibited from road use due to defective brakes, lights or tyres. Towing‑related incidents rose 16 percent between 2022 and 2024.

The Alliance’s TLC campaign urges drivers to perform three pre‑towing checks. Tyres: pressure, tread depth and damage. Load: even distribution, legal limits and securing. Connectivity: lights, electrics and breakaway cables. Member organisations like TyreSafe, the National Caravan Council, the British Horse Society, National Highways, the Camping and Caravanning Club, the National Trailer and Towing Association and NFU Mutual tailor messaging to their audiences.

Tyron specialises in blowout protection. Its patented MultiBand fills the wheel well, preventing the tyre bead from dropping during rapid deflation. This helps drivers maintain steering control to reach safety. The system can also fit alongside Tyre Pressure Monitoring Systems using a dedicated bracket.

The Alliance focuses on education over enforcement, helping drivers take simple steps for safer towing. By combining members’ expertise, it delivers practical guidance from leisure caravanners to agricultural and commercial operators.

Peter Simson, Director, Tyron Runflat, said, “Towing safety depends on multiple factors, but tyres remain one of the most critical elements in maintaining control of both the vehicle and the trailer. We’re pleased to join the UK Towing Safety Alliance and support the TLC campaign, which provides clear and practical guidance for drivers. Collaboration across industry is essential if we are to reduce incidents and improve awareness of the risks associated with towing. By working alongside organisations that share the same commitment to road safety, we can help ensure drivers are better informed and better prepared before they set off.”

Goodyear kicks off its third year as the exclusive tyre supplier for the LMGT3 class in the FIA World Endurance Championship at the 6 Hours of Imola. All 18 cars competing this weekend will be fitted with Goodyear Racing Eagle tyres, continuing a partnership that began in 2024. The chosen compound for Imola is the Medium variant, recognisable by its yellow sidewall lettering, which is valued for its steady performance and reliability across multiple driving stints. This same tyre will be used at every WEC track throughout the current season.

Imola presents a unique test compared to more abrasive circuits thanks to its smooth asphalt and flowing layout that puts less stress on tyres. Lower degradation shifts the emphasis towards strategic planning over the six-hour race, rather than pure tyre preservation. This backdrop is where Richard Lietz and Riccardo Pera previously claimed their first victory together, eventually becoming 2025 LMGT3 champions alongside Ryan Hardwick. They now return with The Bend Manthey Porsche, joined by Yasser Shahin.

New regulations this season have increased tyre allocations, giving teams more strategic freedom. While the Medium’s proven durability still allows double stinting, the extra sets let crews fit fresh rubber at every pit stop, avoiding the need to overextend a stint and risk fading pace. For wet conditions, teams also have access to a Goodyear Racing Eagle Wet tyre, whose tread pattern is engineered to clear standing water and maintain grip.

Beyond the on-track action, the Goodyear Blimp will soar above Imola for its first appearance of the season. The Goodyear Wingfoot Award, decided by fan votes from both the grandstands and home viewers in a driver of the day format, also makes its return. Meanwhile, Goodyear Racing Eagle tyres are competing this weekend at Kansas Speedway in the NASCAR Cup and O’Reilly Auto Parts Series, as well as at Donington Park for the British Touring Car Championship opener.

Stephen Bickley, Goodyear Endurance Program Manager, Said, “Imola is less aggressive on tyres than many of the tracks we visit. It doesn’t generate high lateral loads and the surface is relatively smooth, so it’s naturally one of the kinder tracks on tyres. That opens up a range of strategic options for teams. You can double stint and gain time in the pit lane, or with the increased allocations, teams may choose to run new tyres more often. Our Goodyear Racing Eagle Medium tyre gives them the flexibility to consider both options. The circuit also has a clear left-hand bias, which places more load on the right side of the car. Teams may look at single stinting only the loaded side, while carrying the unloaded side for longer and doing more stints on that side. These differing strategies are what we expect will define the race for many teams this weekend.”
