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.

As part of a strategic effort to increase its presence in the region's premium original equipment (OE) market, Kumho Tire has confirmed its plans to establish its first tyre production facility in Europe by 2027.

The company has shortlisted Poland, Serbia and Portugal as possible locations for the plant, which is projected to need an investment of more than KRW1 trillion (USD 705 million). The decision is closely linked to Kumho’s ambition to strengthen its partnerships with European automakers and was revealed by Kumho Tire CEO during the South Korean premiere of Kumho's new Ecsta Sport tyre line.

Kumho has recently secured OE supply contracts with major brands such as Mercedes-Benz, BMW and Volkswagen Group. At the moment, Kumho runs eight tyre production plants in China, Vietnam, South Korea and the US. Its capacity to compete in the premium OE market, however, has come to be perceived as being constrained by the absence of a European production base. Through the benefits of local production, the new facility will improve response to European client requests, save freight costs and shorten delivery times, all of which will strengthen the company's partnerships.

Sentury Tire USA has opened pre-enrolment for its two associate dealer programmes (ADPs), the Delinte HYPERDRIVE Associate Dealer Program and the Landsail Elyte Associate Dealer Program, underscoring the company’s commitment to rewarding dedication and partnership to the Landsail and Delinte brands.

The ADPs, which are customised for each brand and intended to encourage dealers, will formally start on 1 June 2025. Both programmes give dealers access to special benefits, incentives and strong tools to help them expand their businesses. This involves dependable customer service, effective marketing and worthwhile financial incentives to promote dealers' success at every stage.

Beginning in Q3, dealers may earn up to USD three per tyre through the Delinte HYPERDRIVE Associate Dealer Program. Dealers can receive retroactive benefits for purchases completed in Q2 if they register before 1 June. The awards are available for all Delinte PTR, LTR and the new DV3 LMD AS last-mile delivery tyres. For all Landsail PTR and LTR tyres, independent dealers that sign up for the Landsail Elyte Associate Dealer Program can also earn up to USD three per tyre. For customers who sign up by June 1, the new LMD 100 AS last-mile delivery is also eligible for the benefits and will get the same early bird incentive for Q2 2025.

No initial order is necessary. Dealers only need to register to begin making money. According to the monthly programme rewards structure, 48 tyre purchases each month are eligible for a reward of USD one per tyre, 120 tyres are eligible for a reward of USD two per tyre and 240 or more tyres are eligible for a reward of USD three per tyre.

ENSO, a London-based tyre manufacturer engaged in the production of sustainable tyres specially designed for electric vehicles (EVs), has launched its new ENSO Premium range of EV-specific ultra-high-performance (UHP) tyres aimed at drivers of high-performance EVs such as the Tesla Model 3 and Model Y.

Specifically designed for electric passenger vehicles, the ENSO Premium range comes with A/A EU-label ratings for both energy efficiency and wet grip. The tyres are designed to provide safety, increased range and a reduced total cost of ownership. Conventional tyre designs frequently fall short of the special performance needs of electric vehicles, which include greater vehicle weight, regenerative braking and higher torque loads. By lowering tyre wear and rolling resistance, ENSO Premium takes care of these issues.

The company is an authorised provider of replacement tyres for LEVC's electric taxis and has partnered with Uber to install its tyres in high-mileage metropolitan areas. The company now plans to grow throughout Europe and North America, and with ENSO Premium, it is now offering its services to individual EV owners throughout the United Kingdom. According to ENSO, the range offers advantages including longer tyre life and fewer replacements, lower energy usage, fewer charging stops and lower CO₂ emissions and tyre particle pollution.

Gunnlaugur Erlendsson, CEO and Co-Founder, ENSO, said, “We’re plugging a long-standing gap in the tyre market by offering EV drivers a purpose-built, affordable, premium EV tyre alternative that matches the innovation of their EV.”

Kraton Corporation, a leading global sustainable producer of specialty polymers and high-value bio-based products derived from pine wood pulping co-products, has announced a general price hike in North America for its SBS, SIS and HSBC product lines with effect from 1 May 2025.

Following a careful analysis of the effects of recently implemented tariffs, related cost increases and a conclusion that the company cannot independently absorb these repercussions, Kraton is adopting these pricing hikes, according to a company statement. The company further said that it will keep an eye on the scene and reassess these measures promptly in the event that conditions and US import tariffs alter.
