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.”

Bartell Machinery Systems has announced an expansion of its production facility in Rome, New York, aimed at increasing manufacturing capacity and reducing lead times for customers.

The company is adding 22,400 square feet of high-bay manufacturing space to its existing 152,000 sq ft site. The expansion will include 30-tonne crane capacity, designed to improve material handling, workflow efficiency and flexibility in managing work in progress.

“This expansion of our Rome, New York production facility represents an exciting and important milestone for Bartell Machinery Systems,” said Ben Lunduski, Vice President of Operations of Bartell.

The increased ceiling height will enable the company to manufacture larger and more complex equipment more efficiently. The additional vertical clearance and heavy-lift infrastructure are expected to support improved assembly processes and sequencing of large-scale projects.

Bartell said the investment is intended to increase throughput across multiple product lines, enhance scheduling flexibility and reduce bottlenecks in assembly and testing. The company also expects to expand its capacity to manage multiple projects simultaneously.

“As demand for our large industrial machinery systems continues to grow, this investment reinforces our long-term commitment to our manufacturing operations in Central New York, our customers and our employees,” said Pat Morocco, President of Bartell. “By expanding our production capabilities, we are positioning Bartell for continued success while building a strong foundation for future growth.”

The expansion is also expected to lead to an increase in the company’s workforce to support higher production volumes, contributing to employment in the local area.

Bartell, which produces equipment for the rubber and tyre, wire and cable, and oil and gas industries, said the expansion reflects sustained demand across its product lines and continued growth in recent years. Construction of the facility is at an early stage.

TyreXpo Asia and AutoMROtive will return to Singapore from 17 to 19 March 2027 at Marina Bay Sands, following a well-attended 2026 edition in Bangkok that drew more than 6,000 buyers and sellers from across the tyre and automotive aftermarket sectors.

The co-located events aim to bring together manufacturers, suppliers and solution providers with distributors, dealers, workshop operators, fleet owners and other industry participants from Asia and international markets. Organisers said the combined format is designed to reflect increasing integration across the tyre and automotive maintenance ecosystems.

TyreXpo Asia Singapore will continue to position itself as a marketplace dedicated to the global tyre industry, while AutoMROtive will focus on technologies and services shaping automotive maintenance, repair and operations, with particular emphasis on fleet servicing.

The exhibition will cover a broad range of segments, including passenger car, commercial vehicle and industrial tyres, alongside wheels and related accessories such as rims and tyre fillers. It will also feature tyre manufacturing, retreading and maintenance solutions, as well as automotive components including batteries and braking systems.

In addition, the event will showcase workshop equipment, diagnostic tools and digital maintenance technologies, including predictive systems. Sustainability is also expected to be a key theme, with solutions related to tyre recycling, disposal and waste management included in the line-up.

Organisers said the event is intended to support companies seeking to expand their presence in the region, offering opportunities to connect with distribution networks, generate sales leads and demonstrate new technologies to a targeted industry audience.

Sponsorship and branding options will be available for companies aiming to increase visibility or position themselves as thought leaders within the sector. These can be tailored to support objectives such as lead generation, market positioning and customer engagement.

The announcement comes as companies in the tyre and automotive aftermarket industries begin planning their sales and marketing strategies for 2027, with trade events expected to play a role in facilitating cross-border partnerships and market access in Asia.

Toyo Tire Corporation said Mitsubishi Corporation has ceased to be a major shareholder after tendering its entire holding through a treasury share buyback, ending its status as the company’s largest shareholder.

The change took effect on 10^th August , 2026, following Toyo Tire’s acquisition of its own shares through off-auction trading (ToSTNeT-3). Mitsubishi tendered all its shares, excluding less than one unit, as part of the transaction.

As a result, Mitsubishi is no longer classified as a major shareholder or associated company of Toyo Tire, the company said.

Before the transaction, Mitsubishi held 30,822,206 shares, equivalent to 20.07 percent of total voting rights, and ranked as the largest shareholder. Following the change, its holding has effectively been reduced to zero.

The move follows Toyo Tire’s earlier announcement on August 7, 2026 regarding the termination of its capital and business alliance with Mitsubishi, alongside plans to repurchase its own shares.

Toyo Tire said the change would have no impact on its consolidated financial results.
