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.

Yokohama Tire’s off-road racing contingent is set for a pivotal appearance at the 57th annual Polaris World Championships, scheduled for 4–6 September at Crandon International Raceway in Wisconsin. Known as ‘The Big House’, the venue represents a key stop on the Championship Off-Road season calendar, with Yokohama serving as both the official tyre of the facility and a supporting partner of the racing series.

The team’s lineup features several notable competitors navigating the rugged terrain on GEOLANDAR tyres. Andrew Carlson, a proven contender with multiple podium finishes at Crandon, will pilot his vehicle in the Pro4 class using GEOLANDAR X-AT tyres. Meanwhile, recent Supercross 450 Class Champion Ken Roczen is slated to make his debut at the historic track, competing in the Pro2 class on the same tire model.

Robb Holland is also poised for his first Crandon appearance, trading asphalt for dirt in the Pro Lite division. He will drive a truck belonging to fellow Team Yokohama driver John Holtger, relying on GEOLANDAR A/T4 tyres for his inaugural short-course off-road race. Additionally, team driver Nick Visser enters the weekend holding a narrow lead in the Pro-Spec championship standings, with the title battle intensifying as the season progresses.

Beyond the on-track action, Yokohama will lead the traditional Crandon Labor Day Parade, featuring Carlson and Roczen. The weekend will also include a BassmastHER workshop hosted by Cogan and Carsello, aimed at advancing skills for female participants in the paddock, alongside a VIP and youth fishing tournament held on-site.

Candace Cogan, Director – Product Marketing, Yokohama, said, “We’ve got a great team ready to take on the challenges at Crandon during short-course racing’s most celebrated weekend. They will be ready to face the task on our versatile line of GEOLANDAR tyres. We will once again feature our partnership with Bassmaster with a cool collaboration. Last year we hosted Team Yokohama elite angler, Brandon Palanuik. This time we’ll host Wisconsin native MaggieJo Carsello, a Bassmaster open angler and ambassador for BassmastHER, a female-driven initiative to support a community of female anglers via education, travel and inspiration. We look forward to introducing her to Crandon and the world of short-course off-road racing, something she grew up hearing about.”

Kumho Tire USA recently hosted a national Ride & Drive event at Evergreen Speedway in Monroe, Washington, where over 70 dealers, media professionals and content creators tested the company’s newest tyre models. The gathering served as a key component of Kumho’s broader 2026 regional tour, which has already engaged more than 600 participants across five American cities. Attendees evaluated the newly launched Road Venture HT and Crugen GT Pro tyres through demanding, real-world driving scenarios.

The testing programme featured controlled modules, including a wet handling course, an autocross track for braking and stability assessment and high-speed freeway driving to measure ride comfort. These exercises allowed participants to directly compare the all-season Highway-Terrain Road Venture HT, intended for light trucks and SUVs, against the Crugen GT Pro, a touring tyre built for modern crossovers and larger SUVs. Kumho’s engineers also conducted an educational forum detailing the technological development of both tyres while collecting direct feedback from attendees.

The Road Venture HT, launched earlier this year, offers enhanced wet and snow traction, extended tread life and a quiet ride, and is compatible with electric vehicles. The Crugen GT Pro is engineered for heavier crossover and SUV applications, delivering premium comfort and all-weather capability with one of the highest treadwear warranties in its segment. Available in 85 sizes covering over 85 percent of the current crossover and SUV market, the Crugen GT Pro is backed by a 75,000-mile warranty for H- and V-speed ratings and a 65,000-mile warranty for W-speed models.

Kumho will conclude its 2026 Ride & Drive series with final regional events in Detroit and St. Louis later this month. The company has confirmed plans to extend the programme into 2027 and beyond, ensuring dealers and partners continue to benefit from hands-on product evaluations, technical training and direct access to Kumho’s engineering expertise.

Chris Corwin, Director of Procurement at Discount Tire & Service Centers, said, "A spec sheet has never sold a tyre to a customer standing at our counter. That is why the Kumho Tire Ride & Drive in Seattle was worth every minute. We got real seat time, instead of a sales pitch, running the all-new Crugen GT Pro and Road Venture HT back-to-back in real world scenarios. Having a seat at that table means a lot to me, and it says something about how seriously they take dealer input."

Ed Cho, CEO, Kumho Tire USA, said, “You can read all about a tyre, but nothing compares to driving it yourself, which is why KUMHO has made a significant investment in Ride & Drive events in 2026. These events give our dealers, wholesale partners and retail partners the opportunity to experience firsthand how our latest tyres perform in real-world driving situations. Whether they are evaluating braking, handling, ride comfort or overall performance, attendees can experience the differences for themselves, giving them greater confidence when recommending our products to their customers.”

The AZuR Circular Tyre System has been nominated for the German Sustainability Award Products 2026 in the ‘Resources’ transformation category. This selection places the initiative among solutions deemed by the expert jury as pioneering for advancing a resource-conserving economy.

This circular economy model spans the entire tyre lifecycle, uniting industry partners, retailers, recycling specialists and academic institutions. The framework optimises tyre usage and guarantees high-quality raw material recovery. Repair, reprofiling and retreading prolong useful life, while tyres beyond repair undergo mechanical or chemical recycling to recover valuable secondary materials.

Rather than relying on a single technology, the system's distinctiveness lies in networking stakeholders across the value chain. The award's evaluation highlighted the system's ambition to extend product longevity, prevent waste and sustain raw material circulation, thereby reducing demand for virgin resources.

German market data for 2024 shows approximately 533,000 tonnes of used tyres generated, with 193,000 tonnes mechanically recycled and 20,000 tonnes retreaded. Research indicates retreaded tyre production can reduce CO₂ emissions by over 60 percent, lower raw material usage by two-thirds and cut energy consumption by 50 percent compared to new tyre manufacturing. Products from tyre granulate can save between 1.0 and 3.2 tonnes of CO₂ equivalent per tonne of recycled material.

The nomination drives AZuR to advance Europe's tyre circular economy through extended lifespans, strengthened recycling and digitalisation. The 2026 award winners will be announced on 3 December in Düsseldorf.

Anna Maria Guth, AZuR network coordinator, said, “The nomination is a great recognition for all partners who are working together to further close the tyre cycle. It also shows that the circular economy can be particularly successful when companies, science and other stakeholders do not act in isolation but jointly develop solutions along the entire value chain.”

Bridgestone has released research indicating that over 80 percent of UK motorists believe basic tyre knowledge should be mandatory for new drivers during learning and after passing their test. The survey found that 81 percent of respondents want new drivers to understand correct tyre pressures, tread depth regulations and tyre pressure monitoring systems. Additionally, 57 percent expressed support for graduated driving licences aimed at young motorists, reflecting broader calls for enhanced safeguards during early independent driving.

The findings also reveal strong public backing for more rigorous enforcement, with 67 percent of motorists advocating for tyre safety inspections during routine police traffic stops. Beyond individual owners, 76 percent of respondents asserted that employers should bear greater responsibility for ensuring tyres on all work-related vehicles are properly maintained. Furthermore, 78 percent called for dedicated tyre safety education to be introduced for young people before they reach driving age, underscoring a collective desire for preventative measures that begin well before a first lesson.

The survey results coincide with newly published Department for Transport data showing a significant deterioration in tyre-related road safety outcomes. The number of people killed or seriously injured in collisions involving illegal, defective or underinflated tyres rose by 19 percent year on year, from 169 casualties in 2024 to 201 in 2025. Overall, tyre-related incidents accounted for 667 casualties during 2025, a 14 percent rise from 585 the previous year, while collisions attributed to defective tyres climbed to 447.

This research builds upon Bridgestone’s 2025 study, which identified substantial backing for additional protective measures for novice drivers. Half of respondents supported displaying a recently passed sign for up to 12 months and limiting new drivers to one passenger during their first year, while 39 percent favoured a mandatory refresher course after passing the test and 21 percent endorsed restricting new drivers to a 50-mile radius from home for 6 to 12 months. The findings reinforce Bridgestone's Road Safety Hero campaign, promoting regular tyre checks as part of the company's broader E8 Commitment to enhance driver safety and sustainable mobility.

Helen Roe, Senior Marketing Manager, Bridgestone UK, said, “The latest findings reinforce our belief that tyre safety should play a far greater role in helping young drivers develop safe driving habits from day one. Despite tyres being the only point of contact between a vehicle and the road, tyre maintenance remains one of the most overlooked aspects of vehicle safety. We have seen some high-profile cases of preventable road fatalities due to defective tyres and we can’t stress the importance of knowing the tyre basics and carrying out some simple checks, which can be done in a matter of minutes.

“Learning to drive doesn't stop the day someone passes their test. Developing safe habits, including understanding how to check and maintain tyres, is an important part of becoming a confident and responsible driver. It's encouraging to see such strong public support for improving tyre safety education and ensuring motorists understand the importance of looking after the only part of the vehicle that actually touches the road. Simple checks can make a real difference to road safety, not only for new drivers but for everyone using our roads.”
