Scientists Urge Standardised Approach To Measuring Tyre Wear Emissions In Comprehensive Review

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.

Toyo Tires has made its way to the annual A-List of CDP for its climate change mitigation efforts. This premier recognition, awarded for the first time to the company in the 2025 evaluation, reflects the company’s comprehensive decarbonisation efforts, which include validated science-based targets for cutting greenhouse gas emissions and a shift towards renewable energy at its production sites. CDP’s annual assessment is a key benchmark for corporate sustainability across climate, water and forests.
The assessment also highlighted Toyo Tires' commitment to transparency, as verified by independent third-party data reviews. Viewing its business activities as intrinsically connected to society and the future, the Toyo Tires Group treats reducing environmental impact as a top operational priority.
Moving forward, the company is dedicated to advancing decarbonization across all its manufacturing processes and broader supply chain, aiming to support a sustainable global society.
Apollo Tyres Expands Vredestein Gravel Tyre Range With Aventura Core Series

- January 10, 2026
Apollo Tyres Ltd has introduced a new and more affordable range of gravel tyres under the Vredestein Aventura Core Series. This new-generation family consists of three distinct models: the Aventura Seta Core, Aventura Core and Aventura Grezzo Core. Engineered in Europe, these tyres are built for enhanced durability and dependable performance across diverse surfaces, offering riders a cost-effective upgrade for adventure biking.
The series is constructed around a streamlined Core platform, which incorporates a robust 60 TPI casing for increased puncture resistance and stable handling on uneven terrain. While utilising the proven tread patterns of existing Vredestein gravel tyres, this refined construction delivers high-end capability at a more accessible price point.
Each model is tailored for specific riding conditions. The Aventura Seta Core is designed for speed, with a race-optimised tread for fast rolling on asphalt and high-speed gravel, complemented by shoulder knobs for technical cornering. For versatile, everyday use, the Aventura Core offers a balanced blend of rolling efficiency and predictable grip across tarmac, hardpack and gravel roads. Finally, the Aventura Grezzo Core provides confidence on loose and rugged terrain, featuring an aggressive tread for enhanced traction in sand and soft surfaces, while its chained centre tread maintains efficiency on harder ground.
The Aventura Core Series will be available starting 1 February 2026. The Aventura Seta Core comes in 40, 45 and 50-622 sizes. The Aventura Core is offered in 50-584 and 40, 45, 50-622 sizes. The Aventura Grezzo Core is available in 50-584 and 40, 45, 50-622 sizes. Colour options include black/black and black/transparent sidewalls.
Nic Knippers, Division Head – Vredestein Two Wheel Tyres, Apollo Tyres Ltd, said, “The Aventura Core Series marks an important expansion of our gravel offering within the Vredestein range. By introducing three purpose-designed tyres built on a shared durable foundation, we can better support riders across the full spectrum of gravel terrain – from high-speed racing to off-road exploration and everyday mixed-surface riding.”
Continental Expands HDR 5 And HSR 5 Tyre Lines With New Size

Continental Tires Americas has expanded its HDR 5 and HSR 5 19.5-inch product lines with a new 245/70R19.5 size, specifically engineered for urban and regional delivery fleets.
These tyres are built to endure high-scrub environments and the demanding stop-and-go cycles typical of city routes. Key advancements include a reformulated tread compound that reduces rolling resistance for better fuel economy while also extending tread life. The redesigned sidewall enhances durability to support multiple retreads, maximising the value of each tyre casing. Furthermore, both models are validated for use on electric and hybrid vehicles, as well as traditional combustion engines.
This size extension provides a practical option for fleets seeking to improve operational cost-efficiency and tyre longevity under rigorous driving conditions, continuing the proven performance of the existing series with targeted upgrades.

The Silver Jubilee of the National Institute for Rubber Training (NIRT) commenced on the morning of 9 January 2026 at Kottayam's Hevea Hall. Union Minister of State George Kurian formally inaugurated the event, with Member of Parliament K Francis George presiding. Attendees also heard an address from MLA Chandi Oommen.
A wide array of activities marked the inaugural programme. These included unveiling a commemorative monument, honouring former NIRT Directors and recognising student cohorts. Several publications and materials were launched, such as a Silver Jubilee souvenir and tutorial videos for stakeholders. The new jubilee logo was revealed, and a memorandum of understanding was signed between the Rubber Board and the Government of Nagaland.
The ceremony further involved prize distributions for earlier competitions and celebrated the Diamond Jubilee of Rubber magazine. The day's schedule continued with a curated panel discussion and a dedicated exhibition at the NIRT campus.
