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.

Pirelli has designated the SC0 rear tyre as the new benchmark for Moto2 as the MotoGP World Championship resumes its season this weekend at Silverstone for the 12th round. The Italian manufacturer is supplying its standard range compounds for both support classes, with the updated SC0 making a notable return to the British circuit following its successful evaluation there last year.

The 2026-spec soft rear tyre, which initially debuted as a development prototype, features an altered structure from its predecessor and was universally embraced by competitors during practice sessions, even contributing to a new lap record. Its promotion to the standard lineup sees it joined at the rear by the new medium SC1 compound, formerly a development specification, while front tyre duties are covered by the soft SC1 and the medium SC2 options.

Silverstone presents a formidable technical challenge as the longest venue on the calendar at 5.9 kilometres, demanding exceptional machine and rider performance through high-speed corners and rapid directional shifts. The circuit’s low-abrasion surface and notably wide racing corridor allow for varied lines, adding another layer of strategic complexity to the already fast-paced weekend.

In the Moto3 class, Pirelli has made available the soft SC1 and medium SC2 compounds for both front and rear positions. The majority of the field last year favoured the medium SC2 at both ends, a choice that propelled José Antonio Rueda to victory from the back of the grid, though a segment of riders alternatively selected the softer SC1 option for their machines.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “For this weekend's round at Silverstone, one of the most iconic and technically demanding circuits on the World Championship calendar, Pirelli will once again provide standard range tyres for both classes, featuring the rear soft SC0 compound that made its Moto2™ debut at this very circuit last year as the E0125 development option. The E0125, which complemented the then standard soft tyre, was immediately appreciated by the intermediate class riders, who, on a highly demanding circuit characterised by numerous high-speed corners and changes of direction where stability is essential, focused exclusively on this new solution from Friday onwards.

“Introduced again at subsequent events, the former E0125 quickly became the Moto2™ riders' benchmark, offering greater stability, outright one-lap performance and consistent performance across a wide variety of weather and track conditions. As a result, it was promoted to the new standard soft tyre for this season. More than a year after its debut, and thanks to the significant development work carried out by the teams during this period, the SC0 has already contributed to numerous lap records this season. Weather conditions permitting, it will therefore be interesting to see whether Silverstone can deliver further progress compared with last year's benchmark.”

Hankook Tire, the exclusive tyre supplier for the FIA World Rally Championship, played a central role in the season's 10th round at Secto Rally Finland. The event concluded on 2 August in Jyväskylä, where the company’s Dynapro R213 extreme all-terrain rally tyre was put to the ultimate test across the demanding Finnish landscape.

Competitive action unfolded over 20 Special Stages, covering a total distance of 316.04 kilometres. Renowned as the fastest rally on the WRC calendar, the event subjected vehicles and tyres to extreme speeds. The challenging route was characterised by blind crests that impaired visibility, frequent jumps and narrow forest roads, placing a premium on tyre durability and overall driving stability.

The supplied Dynapro R213 tyre proved instrumental in managing these severe conditions. On the ultra-high-speed gravel sections, it effectively absorbed the impact of repeated landings while delivering consistent grip and precise steering response. Its robust construction ensured reliable performance across the loose dirt and forest roads, allowing competitors to push their vehicles to the limit.

Sami Pajari of Toyota GAZOO Racing claimed a home victory, securing back-to-back wins after his success in Estonia. This result advanced him to second in the Drivers’ Championship with 171 points. Looking ahead, Round 11 is the ueno Rally del Paraguay from 27 to 30 August, featuring gravel stages that will demand exceptional tyre resilience. Hankook applies data from its WRC involvement and other global motorsport events to its R&D, fostering continuous innovation and reinforcing its status as a leading global brand.

Legislation aimed at overhauling decades-old federal tyre safety regulations has been introduced in the United States Senate. The Tire Safety Modernization Act of 2026, sponsored by Senators Roger Wicker of Mississippi and Raphael Warnock of Georgia, seeks to replace outdated testing mandates with contemporary performance standards that better reflect current manufacturing innovations and production techniques.

The proposed bill directs the Department of Transportation to revise federal testing protocols, retiring obsolete requirements in favour of more relevant criteria. A key component of the legislation involves aligning high-speed testing procedures with internationally recognised best practices while also clarifying existing safety criteria to ensure more effective regulatory oversight. The measure preserves a strong emphasis on passenger safety while adapting to the capabilities of modern tyre engineering.

Strong support for the initiative has emerged from the tyre manufacturing sector. Anne Forristall Luke, President and CEO of the U.S. Tire Manufacturers Association, praised the bipartisan effort as a crucial step towards aligning American rules with technological progress, bolstering road safety and enhancing the industry’s global competitiveness. Executives from major manufacturers, including Continental Tire, Goodyear and Yokohama, have similarly endorsed the update, noting that it would allow engineering and compliance resources to focus on innovations that genuinely benefit drivers.

Senator Warnock highlighted the importance of Georgia’s prominent tyre production sector, while Senator Wicker emphasised that federal regulations have failed to keep pace with evolving manufacturing technology. Industry leaders collectively view the act as a thoughtful, science-based modernisation that supports domestic manufacturing competitiveness and ensures that safety standards reflect the demands of modern vehicles, roads and driving conditions across the country.

Bridgestone's e-CENTRE Excellence Programme has delivered a significant financial boost to two community organisations in South London, with nearly GBP 1,000 raised through a charity initiative run by Merityre Southfields, a flagship Bridgestone e-CENTRE. The campaign generated a total of GBP 938, which was evenly distributed between St Michael's Church Social Projects and the Friends of Wimbledon Park, both of which are vital to the Wandsworth area.

Over a five-month period spanning November and December 2025, as well as February to April 2026, motorists were given a one-pound donation token with every Bridgestone tyre purchased. Customers were then able to choose which of the two local causes would receive their contribution, resulting in GBP 464 for St Michael's and GBP 474 for the Friends of Wimbledon Park.

The funds allocated to St Michael's Church Social Projects will finance the installation of an additional water tap at its Kitchen Garden Project, located on the Church Memorial Field. Since its establishment in 2020, the garden has expanded into a productive allotment with over 30 raised beds, providing fresh organic produce for community lunches and a weekly food bank. The new tap is expected to reduce watering time for volunteers, enabling them to dedicate more attention to the retired, unemployed, isolated and vulnerable individuals who rely on the project for support, skill development and social connection.

Meanwhile, the Friends of Wimbledon Park will direct its share towards a new seating area in the Waterfall Garden, with any leftover funds supporting tree and bulb planting as well as maintenance materials. This retail-led effort exemplifies a core component of Bridgestone's broader e-CENTRE Excellence Programme, which has allocated over GBP 1 million to encourage retailers to adopt sustainable practices and foster positive social and environmental change within their localities.

Dene Arnold, Director, Merityre, said, “As a business rooted in the local community, we wanted to give our customers the opportunity to support causes that really matter to people in Southfields. We're incredibly grateful to everyone who got behind the campaign and helped us raise such a fantastic amount. Being part of Bridgestone's e-CENTRE network is about much more than providing premium products and services. It's about making a meaningful contribution to the communities we serve and creating a positive impact beyond the garage doors. It's especially rewarding to know exactly where the money is going. Whether it's helping volunteers continue to grow fresh produce for people in need or creating new spaces for the community to enjoy in Wimbledon Park, these are projects that will make a lasting difference locally.”

Gresia Cabrera, Bridgestone's Business Development Manager and project lead for the e-CENTRE programme, said, “Community engagement sits at the heart of the eCentre philosophy, so it's fantastic to see Merityre Southfields bringing that vision to life. The team continues to demonstrate that modern tyre retailers can be a force for good, supporting local people and causes while delivering outstanding service for motorists. Initiatives such as this show that the industry can make a genuine difference and create value far beyond tyres alone. One of the strengths of the e-CENTRE programme is that it empowers retailers to make a meaningful impact in the communities they serve. Seeing these donations translated into practical improvements that will benefit local people for years to come is exactly what the programme is all about.”
