A comprehensive scientific review released under the umbrella of the Tire Industry Project (TIP) has concluded that despite significant advances in understanding tyre wear emissions, current data remains insufficient to quantify their direct impact on human health. The final paper in a three-part ‘State of Knowledge’ (SoK) series, supported by TIP as part of the World Business Council for Sustainable Development, analysed over 850 peer-reviewed studies to assess global research on tyre and road wear particles. The authors found that inconsistencies in sampling approaches, detection techniques and analytical methodologies across studies prevent reliable comparison and robust risk assessment. As a result, while interest in the topic has grown, the evidence linking tyre emissions to specific health outcomes remains inconclusive.

According to the review, tyre wear particles constitute only a small fraction of total airborne particulate matter, typically less than five percent of PM2.5 and PM10 in urban environments. Toxicological data from both in vivo and in vitro studies indicate that tyre and road wear particles are no more harmful than general ambient particulate matter, with effects that are similar to or less potent than those of other airborne particle types. Although chemicals used in tyre manufacturing have been detected in human body fluids, the authors stress that these substances are also widely used in other applications, making it impossible to clearly attribute exposure to tyres as the primary source.

The paper, independently authored by Kathrin Müller, Julie Panko, Kenny M Unice and Dr Stephan Wagner, identifies the lack of harmonised global methods for sampling, analysing and characterising tyre wear emissions as a major barrier to drawing firm conclusions. This call for greater methodological consistency aligns with the findings of the first two SoK papers published in 2025, which examined the characterisation, quantification and environmental impacts of tyre wear emissions. Without standardised approaches, meaningful comparison across studies and reliable exposure or risk assessment remain unattainable.

Looking forward, the authors recommend that future research prioritise the identification of potential exposure pathways and examine relevant health outcomes, including chronic effects, under realistic conditions. Such studies should cover urban and suburban populations across different global regions to ensure comprehensive and applicable findings. The SoK series, representing the most extensive review of global science on tyre wear emissions to date, underscores the need for coordinated international efforts to improve the identification, measurement, and attribution of these particles in both environmental and human health contexts.

Dr Wagner, one of the leading researchers of Paper 3, said, “Tyre wear emissions are a complex topic that we still only partly understand, especially in relation to human health. While research has advanced our understanding of TRWP, the current data simply isn’t robust enough to quantify any potential health risks specifically linked to tyre wear. Looking forward, cross-stakeholder collaboration is fundamental to making rapid progress. By aligning methods, sharing data and focusing on real-world studies, we can build a stronger, more consistent evidence base to inform future decisions.”

Goodyear has introduced a new global campaign titled ‘Fast Is In Us’, dedicated to celebrating its renowned Eagle performance tyre family. The campaign debuted at the Kentucky Derby and follows last year’s STILL campaign, which underscored Goodyear’s iconic status. Fast Is In Us builds upon that foundation to elevate the Eagle legacy further.

Rather than focusing solely on traditional speed, the campaign highlights individuals deeply passionate about automobiles. It honours their appreciation for vehicle design, engineering and the tactile connection through the steering wheel. Fast Is In Us shifts attention from raw velocity to the emotional bond between driver and machine, celebrating those who feel performance rather than merely claim it.

The Eagle tyre family’s decades-long performance pedigree grounds the campaign, shaped in elite motorsport environments and high-performance automotive partnerships. After 45 years and millions of drivers, Eagle enters a new era believing fast is inherent to its design. This marks Goodyear’s first global campaign built around a performance tyre family, inviting drivers to embrace Eagle as a living philosophy rather than a one-off product.

The campaign will roll out globally across premium television, out-of-home, digital, social and cultural events. At the Kentucky Derby, the Goodyear Blimp carried the phrase Did someone say horsepower? Future integrations include the 24 Hours of Le Mans and other elite racing gatherings. Created with Publicis P1T Crew and led by BBH USA, Fast Is In Us aims to remind performance drivers why Eagle has always belonged with them.

Mark Stewart, Chief Executive Officer and President, Goodyear, said, "The performance car category is growing, and the drivers entering it want tyres worth bragging about. Eagle has more than four decades of credibility in performance and racing, and Fast Is In Us puts that legacy back to work – re‑establishing Eagle as the tyre knowledgeable drivers choose when performance truly matters. This campaign reflects how we're building Goodyear for the future: leading with premium products, authentic performance and brands that mean something."

J J Kraft, VP Global Creative, Goodyear, said, "Eagle isn't a product line – it's a piece of car culture. Fast Is In Us is a comprehensive platform built to put Eagle back at the centre of that enthusiasm. It expresses performance through feel and confidence behind the wheel, not just numbers on a page. It stands as one global campaign idea with the range to live across motorsport, retail and culture, and the ambition to lead the category, not chase it."

"For these drivers, Eagle is more than a tyre, it's a badge of devotion for drivers who respect the craft behind performance and demand confidence, responsiveness, and control every time they drive. Fast, in this world, isn't something you switch on. It's something you live," Kraft added.

The Tire Recycling Foundation (TRF) has officially announced the finalists for its first-ever Circle of Change Awards, a national programme designed to honour individuals, organisations and teams advancing tyre recycling and circular economy leadership. The winners are scheduled to be revealed on 14 May 2026, during the Tire Recycling Conference Awards Luncheon in Denver, Colorado. This year’s conference carries the theme ‘Tread Boldly: Advancing Tire Recycling Through Collective Innovation’.

The pool of finalists spans state-led programmes that have developed scalable and self-sustaining markets for recycled tyres, as well as engineering breakthroughs integrating tyre-derived materials into roads, stormwater systems and urban redevelopment projects. Collectively, these nine initiatives illustrate the expanding innovation and rising demand for tire-derived products across United States.

The awards are structured into four distinct categories, each addressing a critical component of tyre circularity. These include tyre recycling processes, the design and manufacturing of recycled materials, market development for those materials and the complete end-of-life tyre value chain. Together, the finalist projects underscore the creativity and positive momentum shaping the domestic recycled tyre industry.

In the Circular Economy Trailblazer Award category, Colorado and North Carolina were recognised. Colorado has utilised a waste tyre rebate programme and market-development grants to reduce stockpiles and illegal dumping while boosting demand for tyre-derived fuel and moulded products. North Carolina implemented a legislative model that stabilises upstream recycling reimbursements for counties and expands incentives for rubber-modified asphalt applications.

The Innovation in End-Use Technology Award features three honourees. Bolten & Menk constructed a stormwater best management practice system using 210,000 recycled tyres for the city of Woodbury, Minnesota. LHB Engineering and the St. Paul Port Authority applied 30,000 cubic yards of tyre-derived aggregate in underground stormwater retention to redevelop the former Midway Stadium brownfield site. Liberty Tire Recycling, partnering with Atlanta DOT, the University of Georgia, and The Ray, launched an asphalt heat-island pilot to improve pavement durability and study climate and equity benefits in an urban corridor.

For Market Development Excellence, the Alabama Department of Conservation and Natural Resources leveraged rubber-modified asphalt to resurface park roads and parking areas, creating consistent material demand. A Michigan multi-partner effort led by EGLE has scaled recycled tyre applications from pilot projects to hundreds of lane-miles through advanced specifications and coordinated research.

The Value Chain Collaboration Award recognised Bolder Industries and Pirelli Tire LLC for a traceable closed-loop system converting scrap tyres into certified recovered carbon black for new tyre production, alongside Phibro rCB for restarting an idle pyrolysis facility and qualifying recycled materials for tyre manufacturing. An independent panel of industry experts scores all entries based on innovation, measurable impact, scalability and category alignment, with honouree mentions possible at the judges’ discretion.

Stephanie Mull, Executive Director, Tire Recycling Foundation, said, “At the heart of tyre recycling is a simple but powerful challenge: reframe waste from an endpoint into a catalyst for societal value. This year’s nominees show how far we’ve come in turning end‑of‑life tyres into valuable materials that strengthen infrastructure, support communities and protect the environment and remind us that important work still lies ahead.”

Dick Gust, President, Tire Recycling Foundation Board, said, "The Circle of Change Awards recognise bold action and innovation. We honour the innovators, state leaders and collaborators demonstrating that tyre recycling unlocks real solutions and transformation. Each finalist exemplifies what’s possible when visionary action aligns with smart policy and sustained commitment.”
