In an interview with Tyre Trends, Markus Winter, Director of Marketing and Sales at Kokusai Europe, and Kazuhiro Murauchi, Vice President and Head of Engineering at Kokusai Headquarter, share insightful perspectives on the fast-changing reality of tyre testing. With regulatory demands increasing and car technologies developing, Winter shares how the industry responds to new challenges presented by electric vehicles, tighter emission requirements and shifting consumer demands. With Kokusai manufacturing around 130 tyre test machines every year, Winter presents a special point of view regarding the technological advancements and market forces that are determining the future of tyre development and testing practices.

Every nook and cranny within tyre markets across the globe, big or small, is echoing a confluence of old and new practices in the age of new mobility. Attempts to constantly derive upcoming trends are massively influencing stakeholders within the tyre ecosystem as they mull over operational shifts for meeting future demands. The intricate world of tyre testing is also attuning itself to such changes to deliver a seamless transition to end users as progress unfolds.

Markus Winter, Director – Marketing and Sales, Kokusai Europe, contended that tyre testing has surged in recent times as emission norms become stricter and manufacturers methodically formulate new compounds to develop tyres for new-age vehicles.

“Over the past five to 10 years, tyre testing has undergone significant changes driven by regulatory pressures and evolving consumer expectations. In Europe, automotive manufacturers have prioritised high-speed uniformity testing to enhance ride comfort,” noted Winter while speaking exclusively to Tyre Trends.

“Simultaneously, there has been a strong industry-wide push towards improving wet grip, not only for new tyres but also for worn ones. More recently, with the introduction of Euro 7 regulations, the spotlight has turned to wear testing. The emphasis is on minimising microplastic emissions and fine dust particles, aligning with broader environmental and health concerns. As regulatory scrutiny intensifies, tyre manufacturers are expected to invest further in wear-reduction technologies, shaping the next phase of innovation in the industry,” he said.

The Japan-headquartered company that produces around 130 tyre testing machines each year believes that Euro 7 regulations will impose stringent limits on wear particle emissions, leading to a major shake-up within the global tyre industry.

The new rules, targeting a 30 percent reduction in particulate emissions, could disqualify a substantial number of current tyre models from original equipment (OE) fitment on new vehicles. While exact figures remain uncertain, industry estimates suggest that up to 50 percent of existing tyre types may be phased out, with some projections even higher. This has placed immense pressure on manufacturers to accelerate testing and compliance efforts.

The initial response from tyre makers will likely focus on outdoor testing, given its simplicity. However, there is growing consensus that standardised drum testing will be essential for consistent evaluation. Over the next one to three years, demand for advanced wear testing solutions is expected to surge, creating significant business opportunities for testing providers.

At the same time, the industry is closely monitoring regulatory discussions and standardisation efforts as test methodologies continue to evolve. Regional differences are evident with Japanese and European manufacturers prioritising distinct approaches to compliance.

While no dedicated testing equipment for wear particle emissions exists yet, there is increasing interest in integrating sensors and analytical systems into existing tyre wear testing frameworks.

As regulations tighten, companies positioned at the forefront of wear testing innovation will be well-placed to capitalise on the shifting market dynamics.

SHIFTING DYNAMICS

The rise of electric vehicles (EVs) is fundamentally reshaping the tyre testing industry. With EVs requiring bigger, heavier tyres and delivering significantly higher torque, testing methodologies must adapt to these changing dynamics.

“With EVs demanding bigger, heavier tyres and generating higher torque, the industry must adapt. Our testing concepts are divided into two key areas including force and moment testing, which accounts for the torque and velocity changes and endurance testing such as tyre wear assessments. While high torque isn’t a requirement for endurance testing, these machines must still meet rigorous performance standards,” noted Winter.

Another major transformation is the accelerated development cycle of new tyres. Previously, a single tyre model would take six months to a year to develop, but manufacturers are now introducing new models every three months. Each iteration features different materials, tread designs and wear characteristics, increasing the need for highly flexible and efficient testing solutions. “This shift creates a greater demand for flexible, high-throughput testing solutions. We’ve opened a technical centre in Tokyo, where manufacturers can evaluate new tyre designs and test methods in real time,” informed Murauchi.

Smart tyre technology is also influencing the testing landscape. According to the executive, tyre testing involved manually recording data such as temperature, pressure and wear characteristics in the past. Today, with the integration of tyre pressure monitoring system sensors and RFID tracking, data collection is becoming increasingly automated. These advancements allow for real-time analysis and improved accuracy in performance evaluations. Although not all tyres currently include RFID technology, the trend is clearly moving towards fully automated data integration.

High-speed uniformity testing is another area undergoing transition. “Demand for this type of testing peaked several years ago, particularly for performance and luxury vehicles. However, as EVs continue to grow heavier, the impact of uniformity variations at high speeds has diminished. A vehicle that is 500–800 kg heavier places less emphasis on tyre uniformity, making it less of a critical factor for the driver. Despite this trend, high-speed uniformity testing remains essential in laboratory settings, where it provides valuable insights into braking performance, torque application and wet grip. While production-line high-speed testing has seen a slight decline, laboratory testing remains a necessary step in ensuring that EV tyres meet safety and performance standards,” noted Winter.

Investment trends in the industry also reflect this evolving landscape. Many tyre manufacturers are opting for outdoor testing because it requires lower upfront investment. Outdoor tests can be conducted by hiring test vehicles and drivers rather than investing in costly laboratory equipment.

Nonetheless, core testing parameters such as uniformity, geometry and balance will remain essential despite the shifts, noted the executive.

INTELLIGENT MACHINES

Winter noted that artificial intelligence (AI) will also play a significant role in tyre testing, particularly in analysing wear test results. While machine builders focus on developing equipment that ensures precise and reproducible testing conditions, AI is increasingly being used in areas like shearography testing.

“For now, AI’s role in direct test result analysis remains limited as interpreting the data largely falls to manufacturers. Testing machines must guarantee consistent results under identical conditions ensuring uniform abrasion rates. However, manufacturers leverage AI to assess tread compounds and wear conditions, an area beyond the machine builder’s core business,” said Murauchi.

Software is also becoming increasingly important in tyre testing, though integration varies by manufacturer size. Major companies prefer to use proprietary quality tools and focus on seamless data integration.

Smaller manufacturers, however, seek guidance on handling test data, creating opportunities for collaboration with software firms.

Despite handling vast amounts of test data, the company is not pursuing a business model centred on data analytics or test services. Some competitors have expanded into internal testing and data-driven solutions, but this firm remains committed to machine building.

UPGRADING SYSTEMS

Customers today are increasingly seeking testing machines that can be upgraded rather than replaced after 15–20 years. Their expectation is to minimise costs while extending the machine’s lifecycle, though upgrading a machine directly in a customer’s plant at minimal cost is not always feasible. Despite this, manufacturers are focusing on designing equipment that allows for easier upgrades over time.

“One key aspect of this shift is the move away from hydraulic systems. All of our testing equipment is now fully electric, whether it is a compression tester, steering tester or vibration tester. This transition was influenced by Japan’s experience with earthquakes, particularly the 2011 disaster that led to power shortages. Following the Fukushima incident, the Japanese Government required manufacturers to reduce power consumption by 15 percent. Unlike hydraulic systems, which require stable oil temperature and pressure, our fully electric machines can be turned on and off instantly, making them more energy-efficient and reducing operational downtime,” averred Murauchi.

The focus on energy efficiency extends to long-term improvements in machine performance. Over the years, the company has developed systems that significantly reduce electricity consumption. Since tyre wear testers run for long durations daily, its energy usage directly impacts operating costs.

“We developed an innovative drive concept that provides force-synchronised control of the drum and test tyre, allowing tyre slip to be precisely applied via a highly dynamic torque-on-demand system. Combined with our specially adapted load case collective, this new system achieves a nearly 90 percent reduction in energy consumption compared to conventional hydraulically driven wear testers. As a result, we can dramatically reduce the running cost for our customers. The first sets of these advanced systems have already been successfully implemented at a major Japanese company, demonstrating the effectiveness of our energy-efficient approach,” revealed Winter.

REGULATORY CHANGES

Regulations play a critical role in shaping the tyre testing industry as manufacturers continuously adapt to new requirements. Winter anticipates significant regulatory changes, particularly in Europe and Asia, over the next four to five years that will impact tyre testing and development.

“One of the key upcoming regulations is related to tyre wear. There is increasing focus on how quickly tyres wear out and how that affects road safety and environmental impact. In addition to wear, the wet grip performance

of tyres is expected to come under stricter regulations, pushing manufacturers to provide more transparent data on its products’ real-world performance. Another area of growing interest is tyre lifespan, particularly for commercial truck and bus tyres. Customers are becoming more focused on the overall service life of tyres rather than just wear resistance, which means testing procedures may need to evolve,” said Winter.

“Tyre safety is another area where regulations are expected to tighten. In the past, tyre testing has primarily focused on new tyres, but we foresee that future regulations may require testing on worn tyres as well. This is because a new tyre performs optimally, but its behaviour can change significantly after use. Factors such as tread depth, air pressure variations and temperature fluctuations influence how a tyre performs over time, and regulators may demand better data on these aspects,” he added.

Currently, tyre testing is done under standard conditions, but in reality, tyres are used in extreme temperatures ranging from sub-zero to scorching heat. With the rise of autonomous driving, there is an increasing need for tyres to be tested in a variety of weather conditions.

Future regulations may require more comprehensive testing to ensure that tyres perform predictably across different temperatures, humidity levels and road conditions. Autonomous vehicle systems will likely rely on detailed tyre performance data to make real-time driving decisions, which could drive the development of new testing methodologies.

FOOTPRINT

Asia remains the strongest market for the company, where it has established itself as the market leader with deep customer relationships. While competition is intense in Europe, the company has tested its machines with premium manufacturers and is adapting its equipment to meet the specific needs of different tyre makers.

The company is deploying pilot projects across various segments including passenger car and truck tyres to expand in Europe. These initial installations allow for extended testing before securing approvals to participate in larger procurement processes. In contrast, the wear tester segment is less competitive with only a few global suppliers, positioning the company as a key player with extensive collaborations worldwide. The focus now is on strengthening technical partnerships, installing pilot units and integrating its solutions within the operational frameworks of major tyre makers.

The company has set a target to expand capacity to 150 units per year, potentially by the end of 2025. While European markets face margin pressures, the company’s challenge lies in scaling up production in Asia, US and Europe to meet growing global demand.

Goodyear Tire & Rubber reported a net loss of USD 2.2 billion for the third quarter of 2025, weighed down by significant non-cash charges, even as its “Goodyear Forward” transformation programme continued to deliver strong operational benefits and major divestitures were completed.

The tyre maker said segment operating income rose to USD 287 million in the quarter, reflecting USD 185 million in cost-saving benefits from Goodyear Forward, which helped offset inflationary pressures, lower volumes and the absence of prior-year insurance recoveries.

“We delivered a meaningful increase in segment operating income relative to the second quarter in an industry environment that continued to be marked by global trade disruption,” said Mark Stewart, Chief Executive Officer and President. “This growth underscores our strong product portfolio and the consistency of our execution under the Goodyear Forward plan, both of which we expect to support further acceleration in our earnings during the fourth quarter.”

Goodyear’s quarterly net sales were USD 4.6 billion, with tyre unit volumes at 40 million. The company recorded a USD 1.4 billion non-cash deferred tax asset valuation allowance and a USD 674 million goodwill impairment charge during the quarter. Adjusted net income was USD 82 million, compared with USD 102 million a year earlier.

The company stated that all planned asset sales under its Goodyear Forward plan had now been completed, generating total gross proceeds of approximately USD 2.2 billion, which will be used to reduce debt and reinvest in growth.

On 31 October, Goodyear finalised the sale of the majority of its Goodyear Chemical business to an affiliate of Gemspring Capital Management, LLC, for USD 650 million, subject to adjustments. At closing, Goodyear received approximately USD 580 million in cash, which reflected working capital adjustments, including those for intercompany receivables.

“With the sale of our Chemical business, we have completed all of the planned asset sales included in our Goodyear Forward transformation program,” said Stewart. “Additionally, we surpassed initial expectations, with total gross proceeds from the divestitures of approximately USD 2.2 billion. As a result, we have a more focused, streamlined portfolio that will allow us to grow our core products and services and achieve our vision of being #1 in Tires and Service.”

The sale included Goodyear Chemical facilities in Houston and Beaumont, Texas, as well as a research office in Akron, Ohio. The company retains its chemical plants in Niagara Falls, New York, and Bayport, Texas, as well as the rights to the products produced there.

By region, the Americas segment reported third-quarter sales of USD 2.7 billion, a 4.2 percent year-over-year decline, as replacement tyre volumes decreased due to high inventories of imported products in the US market. Segment operating income fell to USD 206 million from USD 251 million.

In Europe, the Middle East and Africa (EMEA), sales rose 4.4 percent to USD 1.4 billion, supported by favourable currency movements and stronger price/mix. Operating income increased to USD 30 million from USD 23 million a year earlier.

Asia Pacific sales fell 18.9 percent to USD 501 million, reflecting the sale of the Off-the-Road (OTR) tyre business and softer demand in Japan, Australia and China. Segment operating income dropped to USD 51 million from USD 72 million.

Goodyear said it expects to achieve about USD 1.5 billion in annualised run-rate benefits from the Goodyear Forward programme by the end of 2025.

Tomoshige “Tomo” Mizutani, advisor and former Chairman and Chief Executive of Nitto Tire USA Inc., has been inducted into the Tire Industry Hall of Fame, one of the sector’s most prestigious honours.

The induction, hosted by the Tire Industry Association (TIA), will take place in Las Vegas alongside the 2025 SEMA Show, running from November 4 to 7.

With more than four decades in the tyre industry, Mizutani is widely credited with transforming Nitto Tire USA from a struggling operation in the early 1990s into a billion-dollar brand recognised for its innovation, performance, and strong connection with car enthusiasts.

“Our 2025 inductees embody the spirit of innovation and service that defines the tyre industry,” said Dick Gust, CEO of the Tire Industry Association. “Their contributions have improved safety, expanded opportunity, and shaped the way we do business worldwide.”

Mizutani’s approach combined deep market insight with bold risk-taking. By engaging with emerging communities of young car enthusiasts and later expanding into the off-road segment, he helped reposition Nitto as a brand built around passion and creativity.

Known for embracing innovation, Mizutani was among the first to champion enthusiast-driven product development and leverage digital and social media marketing to build brand loyalty. Under his leadership, Nitto cultivated a social media community exceeding 13 million followers, making it one of the most engaged automotive brands online.

“When new game-changing innovations would arise,” Mizutani said, “we viewed them as huge opportunities instead of risks.”

A frequent speaker at leading universities and industry events, Mizutani has shared his philosophy of creativity, resilience and perseverance with aspiring business leaders, often reminding audiences to “never ever give up.”

“This honour is beyond my dreams,” Mizutani said. “I’ve been privileged to meet and learn from industry legends who inspired me since my first day in America. I am deeply grateful for the incredible people who have guided, challenged, and supported me throughout my journey.”

Finnish tyremaker’s third-quarter operating profit surges 427 percent to 21.8 million euros. Romanian factory ramp-up progressing as planned, now operating 24/7. Heavy investment phase nearing its end as the company targets a cash flow turnaround.

Finnish tiremaker Nokian Tyres reported a more than fivefold increase in third-quarter operating profit, as aggressive pricing increases in passenger car tyres and improved manufacturing efficiency offset challenging market conditions and years of operational upheaval.

The company, known for its winter tyres, said operating profit jumped 427 per cent to 21.8 million euros ($23.7 million) in the July-September period from 4.1 million euros a year earlier, when results were dragged down by 13.3 million euros in inventory write-downs related to contract-manufactured products.

Net sales grew 10.8 percent to 344.1 million euros at constant exchange rates, with the company achieving growth across all regions despite what it characterised as stable replacement tyre markets in Europe and declining conditions in North America.

“I have to say that I’m very pleased to tell you that we are really moving in the right direction,” President and Chief Executive Paolo Pompei told analysts on a conference call. “Our operating profit increased significantly. Obviously, this is very encouraging for the future journey that we have ahead.”

Pricing Strategy Delivers Results

The improvement was driven primarily by price increases implemented from late in the first quarter onward to offset rising raw material costs and to reposition products in Central Europe and North America, Pompei said.

In the passenger car tyre segment, which accounts for the bulk of Nokian’s business, net sales rose 13.2 percent to 234 million euros, whilst segment operating profit climbed to 38.9 million euros from 34.4 million euros. The segment’s operating margin rose to 16.6 percent, up from 16.4 percent a year earlier.

Interim Chief Financial Officer Jari Huuhtanen said price and mix effects contributed a positive 35 million euros to operating profit in the passenger car tyre segment in the quarter. However, this was partially offset by 25 million euros in supply chain costs, related mainly to non-recurring items from the previous year.

“Our average sales price with comparable currencies improved, and the sales of higher than 18-inch tyres increased significantly,” Huuhtanen said. “Segment operating profit improved due to price increases and a favourable product mix.”

Pompei acknowledged that volume declined 3.3 percent in the quarter but said this was “well justified by the comparability with the previous year, due to the action we made in order to release the slow-moving stock that we have accumulated due to the crisis in the Red Sea channel.”

Asked about the sustainability of price increases, given that larger competitors have recently lowered their price-mix assumptions, Pompei said: “We cannot keep increasing pricing. It was extremely important for us, again, to compensate for the increase in rising raw material costs and, at the same time, to gradually reposition in Central Europe and in North America.”

He added that the company was “not expecting the price increase to affect volume at this stage” beyond the comparison effects from last year’s inventory clearance.

Romanian Factory Hits Milestone

The company’s new factory in Oradea, Romania - described as the world’s first full-scale zero-CO2-emissions tyre factory - is progressing according to plan and is now operating four shifts to enable round-the-clock production.

Nokian said it would deliver approximately one million tyres from the Romanian plant this year, up from zero in 2024. The factory began customer deliveries in the second quarter.

“One million is the production, but the capacity already by the end of the year will be up to three million pieces and up to the end of next year, up to six million pieces,” Pompei explained. “We need to distinguish between production and capacity.”

He said the remaining capacity expansion would focus on mixing and semi-finished product lines rather than curing and building machinery, meaning capital expenditure requirements would be “really limited” for the next three years.

The Romanian facility has launched two new product lines for Central and Southern European markets, most recently the Powerproof 2, a premium ultra-high-performance summer tyre unveiled at an event in Spain attended by 160 guests from across the region.

Pompei said that in future, “more than 80 percent of what we sell in the European market will be supported by our Romanian factories for Central Europe as well as South Europe.”

North America Shines, Heavy Tyres Struggle

North America emerged as a standout performer, with sales surging 27 percent despite a declining market, driven by favourable tariff developments.

“We are finally doing extremely well in North America, and we are very pleased with the journey that we have done so far,” Pompei said.

Canada removed 25 percent counter-tariffs on U.S.-produced tyres on 1 August, whilst the United States reduced tariffs on EU tyre imports from 25 percent to 15 percent on 1 September. Nokian produces approximately 85 per cent of its U.S. volume at its Dayton, Tennessee, facility.

“Obviously, today we are in the ideal situation to deliver tyres from the US to Canada without duties,” Pompei said.

The company also disclosed a new partnership with American Tire Distributors (ATD), the largest national distributor in the United States. However, Pompei noted exposure was “relatively low” as the relationship was beginning.

However, the heavy tyres division struggled, with net sales falling 4.4 per cent to 55.4 million euros at constant exchange rates, as weakness in truck and agricultural tyre markets persisted. Segment operating profit dropped to 5 million euros from 7.5 million euros, impacted by lower volumes and inventory revaluation effects.

Asked when the agricultural market might recover, Pompei said: “I believe the agri business in particular is subject to cycles, and cycles can be long or short, but in general, obviously, we are now landing at the end of the second, I would say almost the second year of a downturn.”

He added: “I’m expecting the agri business at the level in particular to recover pretty soon in the next six to 12 months.”

Winter Season Outlook, Efficiency Drive

Looking ahead to the crucial winter tyre selling season, Pompei said the weather in September had been “a little bit too warm” but conditions were improving.

“Now it is getting colder, both in the Nordics as well as in North America,” he said. “We are expecting the winter tyre season to basically start, as I speak in this moment in November.”

The company’s flagship winter products continued to receive strong reviews, with the Hakkapeliitta 10 studded tyre and Hakkapeliitta R5 non-studded tyre taking top positions in multiple European tyre tests.

Nokian also announced it had begun personnel negotiations in Finland regarding efficiency improvements, which have resulted in eight permanent white-collar job cuts.

“This is part of our journey when we want to improve efficiency and productivity,” Pompei said. “This is necessary to support the company in this journey.”

The company’s Vianor retail chain reported improved performance, with net sales rising 7 per cent at constant exchange rates to 74.9 million euros, whilst the segment’s operating loss narrowed to 6.4 million euros from 6.6 million euros.

Nokian maintained its 2025 guidance unchanged, expecting net sales to grow and segment operating profit as a percentage of net sales to improve compared with the previous year.

The company said tyre demand in its markets is expected to remain at 2024 levels. However, it cautioned that “development of the global economy as well as geopolitical, trade and tariff uncertainties may cause volatility to the company’s business environment.”

For the first nine months, net sales grew 9.4 percent to 957.3 million euros, whilst segment operating profit rose to 40.2 million euros from 35.4 million euros. Segment EBITDA margin improved to 14.1 percent from 13.5 percent.

Asked about margin volatility in the passenger car segment, which has swung sharply on a quarterly basis over the past two years, Pompei said stability should improve.

“Of course, you will see more stability in the development of the margins moving forward, because now, finally, we can leverage our increased capacity, we can leverage an efficient manufacturing footprint,” he said.

Goodyear Tire & Rubber is consolidating its aviation tyre business under a single global structure and has named Joe Burke as Vice President of its Global Aviation business, effective Friday.

The reorganisation reflects the company's efforts to streamline operations and better serve customers across commercial, military and private aviation sectors, Goodyear said in a statement.

Burke, who has spent more than a decade at Goodyear, working across its commercial and aviation segments, will report to Grégory Boucharlat, Senior Vice President of Global Commercial Operations.

"Aviation is a strategic and high-value segment for Goodyear, and we're proud of the legacy we’ve built over the past century," said Boucharlat. "By aligning our global capabilities, we're better positioned to serve our customers with some of the industry's most trusted products and services. Joe's leadership and experience will be instrumental in driving the next chapter of Goodyear's growth in aviation."

The Akron-based tyremaker has supplied the aviation industry for more than a century, developing the world's first pneumatic aircraft tyre in 1909. Commercial airlines, military fleets and private aircraft operators use its products.

The aviation division represents a key component of Goodyear's portfolio, though the company did not disclose financial details about the segment’s contribution to overall revenue.
