Continental has launched dimensions of the AllSeasonContact tyre with a rolling resistance class A rating – the best possible rating for the EU tyre label. Four out of the five tyre sizes bear an XL identifier, so they can carry heavier loads. This combination makes the tyre the ideal retrofit option for electric vehicles, as it can carry the higher average weight and extend the range of e-cars, the company claimed in a press release. 

Continental will initially present the AllSeasonContact tyre with rolling resistance class A in five sizes that can be used to retrofit electric vehicles such as the Hyundai Kona Electro, Kia e-Niro, Peugeot e-2008 and Opel Mokka-e for year-round use.  

For this version of the AllSeasonContact, the developers were able to reduce the amount of material and further optimise the rolling resistance of the rubber compound, the release said, adding that these measures reduce tyre deformation in the contact patch. As a result, the AllSeasonContact loses less energy to the road – the main cause of rolling resistance.

Andreas Schlenke, Tyre Developer at Continental, said, “We’re convinced that there is no one-tyre-fits-all solution for all-electric vehicles. Instead, we have been working for over a decade on developing our existing portfolio so that it meets the requirements of all electric vehicles and at the same time can sustainably reduce emissions from combustion vehicles as well. We’re proud to be one of the first tyre manufacturers to successfully optimise the rolling resistance of an all-season tyre significantly without any loss of safety.”  

Low rolling resistance also has positive effects for combustion vehicles, the release said. It reduces CO2 emissions and consumption, which cuts fuel costs. At the same time, fleet operators can save on expenses for tyre replacement and storage by using all-season tyres. 

Continental’s first three sizes also cover popular fleet vehicles. For example, the AllSeasonContact with particularly low rolling resistance is now also available in sizes for the VW Passat (Elegance, GTE) and the Skoda Superb (STYLE, Premium Edition).

Continental said it has already received approvals for the AllSeasonContact with rolling resistance A for the VW Transporter and Caddy as well as Jeep Compass. For all models, the tyre can also be retrofitted via dealers. 

The AllSeasonContact combines elements of Continental’s Premium summer and winter tyres. In the all-season tyre test conducted by AutoBild (on 24 September, 2020), the tyre was rated “exemplary” for its all-round capabilities and good price-performance ratio. Overall, the all-season tyre is available in 142 versions, with widths between 155 and 275 millimeters, cross sections between 70 and 35 percent, and rims with diameters of 14 to 20 inches. (TT)  

Research analysing 850+ studies reveals fragmented methodologies hampering understanding of environmental impact

Scientists have called for urgent standardisation of methods used to measure and assess tyre wear emissions, following publication of what they describe as the most comprehensive review of research in the field to date.

The "State of Knowledge" series, which analysed more than 850 peer-reviewed scientific publications spanning four decades, has revealed significant gaps and inconsistencies in current understanding of how tyres shed particles and chemicals during use.

The research highlights how fragmented approaches across different studies have prevented scientists from drawing definitive conclusions about the environmental and health impacts of tyre wear emissions, which occur when tyres interact with road surfaces during driving.

"The topic of tyre wear emissions is extremely complex, multi-dimensional, and unfortunately only partially understood," said Dr Stephan Wagner, one of the paper's lead authors. "Until these gaps are closed, there is a growing concern that decisions about tyre emissions could be based on incomplete science."

The first two papers in the three-part series focus on characterising tyre wear emissions and assessing their environmental impact. A third paper examining potential health impacts is expected later this year.

The research, supported by the Tire Industry Project - part of the World Business Council for Sustainable Development - found that tyre wear creates not just particles but also releases volatile compounds and dissolved chemicals that can leach into the environment.

Current data suggests the risk from most tyre and road wear particles in water and soil is "generally lower down the priority list", according to the environmental risk assessment paper. However, researchers said insufficient data exists on tyre leachables and volatile compounds to make a full assessment.

The studies propose a tiered measurement framework and call for harmonised testing protocols to enable meaningful comparisons between different research efforts.

"The SOK underscores why we need a concerted, multi-stakeholder response to close the knowledge gaps, now more than ever," said Larisa Kryachkova, executive director at the Tire Industry Project.

The research comes as regulators worldwide grapple with how to address microplastic pollution, including particles from tyre wear. The European Union has been considering regulations on tyre emissions as part of broader environmental protection measures.

The authors suggest existing frameworks for assessing microplastics could provide a starting point for developing tyre emission guidelines, with modifications to account for the unique characteristics of tyre wear materials.

"We hope that these papers will encourage the scientific community and serve as a catalyst for further research and standardisation," Wagner concluded.

The Tire Industry Project plans to host a research conference at MIT in Boston to promote collaborative approaches to addressing the knowledge gaps identified in the review.

Japanese tyre maker launches cost-cutting initiative as US tariffs bite

Sumitomo Rubber Industries maintained its full-year profit forecast despite a sharp decline in first-half earnings, as the Japanese tyre maker launched a comprehensive cost-reduction programme to counter rising raw material costs and US trade tariffs.

The company reported business profit of 28.3 billion yen for the six months ended June 30, down 33 percent from the previous year, whilst sales revenue fell  three percent to 572.2 billion yen. Profit attributable to shareholders plunged 63 percent to 14.4 billion yen.

Despite the weak first-half performance, Sumitomo Rubber held its full-year business profit target at 95 billion yen, representing an eight percent increase from the previous year.

"At the initial planning stage for H1, we anticipated significant negative impacts from rising raw material costs, particularly natural rubber, as well as foreign exchange fluctuations," President and CEO Satoru Yamamoto told analysts. "Overall, performance progressed largely in line with our plan."

The company faces headwinds from US tariffs imposed under the Trump administration, with an estimated impact of 14.5 billion yen for the current fiscal year, down from an initial estimate of 18 billion yen following tariff postponements and rate reductions in Japan and Indonesia.

Project ARK targets 30 billion yen savings

To bolster profitability, Sumitomo Rubber launched "Project ARK," a company-wide cost-reduction initiative targeting 30 billion yen in cumulative savings by the end of 2027 from its 1.1 trillion yen annual cost base.

"By advancing Project ARK, which carries forward the direction of the Be The Change initiative, we intend to help build a robust management foundation that is resilient to such external changes," Yamamoto said.

The programme focuses on tyre production costs, shared administrative and R&D expenses, and non-tyre business segments. General Manager Shinji Araki, who leads the project, said the company expects to achieve "several billion yen" in savings this year, ramping up to approximately 10 billion yen in fiscal 2026.

Dunlop brand expansion progresses

The company began selling tyres under the acquired Dunlop brand in North America and Australia in May, following the completion of its trademark acquisition from Goodyear Tire & Rubber. Sumitomo Rubber plans to launch proprietary Dunlop products for the North American market in January 2026, with European sales to follow.

"By introducing differentiated products manufactured by the Company under the DUNLOP brand in Europe, North America, and Oceania, we aim to increase the proportion of premium products," Yamamoto said.

The company's proprietary Active Tread technology, featured in its Synchro Weather tyre launched in Japan last October, won multiple industry awards and is being developed for next-generation all-season tyres targeting European and North American markets for a 2027 launch.

Tariff impact manageable

Sumitomo Rubber began implementing price increases in the US  market in May to offset tariff impacts, with Managing Executive Officer Hidekazu Nishiguchi saying progress has been "generally in line with our plan."

The company estimates it can recover approximately 10 billion yen of the 13.5 billion yen tariff impact on its tyre business through price increases, with the remainder offset through cost reductions and expense controls.

"Since we primarily ship from Thailand, the tariff is applied to the export price from Thailand. As a result, we estimate the effective tariff burden to be around 12% to 13%," Nishiguchi explained.

For the full year, Sumitomo Rubber forecasts sales revenue of 1.215 trillion yen, unchanged year-on-year, whilst maintaining its interim dividend at 35 yen per share with a projected year-end dividend of 35 yen for a total annual payout of 70 yen.

The company's tyre sales volume is expected to decline four percent to 99.03 million units for the full year, though it continues to focus on premiumising its product mix, with premium tyres forecast to account for 46 percent of passenger car tyre sales, up from 44 percent previously.

During the recent BASF Demo Day at Hurcott Farm, Trelleborg Tires presented its advanced tyre technologies to an audience of agricultural professionals. The farm's operators, Mark, Sue and Andrew Doble, facilitated hands-on demonstrations that highlighted the tangible benefits of proper tyre pressure management in real-world farming scenarios.

The company's VF (Very High Flexion) tyre technology took centre stage, demonstrating its ability to operate effectively at reduced inflation pressures. This engineering breakthrough allows for improved weight distribution across a larger contact area, significantly decreasing soil compaction while maintaining optimal traction. Such advancements contribute directly to preserving soil health and enhancing long-term field productivity.

Complementing this innovation, Trelleborg's ProgressiveTraction tread design exhibited its dual functionality – delivering exceptional field performance without compromising on-road comfort. The unique dual-anchor lug configuration provides multidirectional grip, effectively reducing wheel slippage and improving fuel efficiency across various terrain conditions. An integrated Interlug system further enhances operational performance through superior self-cleaning capabilities and stability.

To support customer investments, Trelleborg extends a comprehensive 5,000-hour warranty on select ProgressiveTraction models when registered through their Premium Care initiative. Industry partner C&O Tractors, renowned Massey Ferguson specialists, participated in the event, showcasing the synergistic benefits of combining premium tyre technology with high-performance agricultural machinery.

This demonstration underscores Trelleborg's ongoing commitment to developing innovative solutions that address the evolving needs of modern agriculture. By focusing on technological advancements that promote sustainability and operational efficiency, the company continues to deliver measurable value to farming professionals worldwide.

Craig Churstain, Sales Manager, Trelleborg Tires, said, “Optimising tyre pressure between field and road applications is one of the most effective, yet often overlooked, ways to boost farm efficiency. Lower pressure in the field means less soil compaction and healthier crops. On the road, it ensures better fuel efficiency and longer tyre life. It’s about getting the most from every working hour. Farmers today are under constant pressure to do more with less. Our mission is to provide tyre solutions that not only perform in the toughest conditions but also support a more sustainable and profitable farming model.”
