Tyre testing is not a new concept. In fact, is there any industry that can do without tests? However, what tyre testing does bring into consideration is an umpteen number of factors – everything from the road wear to the certification, the testing spots and, of course, the different types of testing and the very tyres themselves. Discussing these very aspects with Tyre Trends, Ismo Halén, Vice President at BD Testing Inc, spoke about Black Donuts, the subjective and objective views of tyre testing, the convenience of BD Testing having its own indoor testing facility and more. Read on…

The name Black Donut is self-explanatory, making it rather individualistic. A tyre resembles a donut and is black in colour – simplicity at its best. Black Donuts offers a range of solutions for tyre product development and testing, tyre factory construction, plant process design and process development. Therefore, Black Donuts has many business areas, and one of them is service in product development. When it comes to testing, Black Donuts owns 90 percent of another company, BD Testing Inc, which is into tyre testing and high-end customer service. Plus, Black Donuts also happens to be one of BD Testing’s customers.

BD Testing’s customers
When we caught up with Ismo Halén, Vice President at BD Testing Inc, he told us, “Black Donuts designs new tyres and new tyre models or improves existing tyres. That’s why they need testing in order to support the product development. Black Donuts Engineering was founded in 2011, and we were a test team within the company in the beginning. However, we separated in 2012 into an individual company, and now we have separate management and everything else that’s individually ours. We don’t have anyone from Black Donuts working at BD Testing. They are only one of our customers.”

And as customers, they can always decide who tests their tyres. “For instance, Black Donuts can use BD Testing for product development testing because we understand each other. However, the customer can  reach out to other companies to test their tyres as well. For example, when a product is finished, customers usually make homlogation tests somewhere else,” Halén explained.

When it comes to customers/clients, Halén mentioned that it’s not exactly easy to acquire new clients. However, he added, “I’m happy because we already have so many customers that even if somebody doesn’t order anything that others do, we are still in a very good situation.” When turning to his plans on approaching any Asian manufacturers, he responded that while they don’t have any plans for Asia, they would consider going there if there are proving grounds that can be used or rented.

BD Testing’s various focus areas
BD Testing goes beyond this and also issues certification. It has a quality system and is accredited for some R117 tests. “This includes rolling resistance, wet grip, noise measurement and snow performance,” Halén mentioned and continued, “Earlier, we would do wet grips, noise measurements etc. But just one year ago, we started focusing more on winter testing. We now conduct snow and ice tests for the label, which comes under the R117 tests. Additionally, we provide technical service to The Netherlands Vehicle Authority (RDW). RDW will issue many types of approvals for many tyre manufacturers, and we can conduct snow tests for them.”

“Furthermore, in Nordic countries, we use studs in the tyre, which has to be approved. Besides, we make road wear testing for studded tyres, which needs mandatory approval from the Finnish Transport Safety Agency, TRAFI,” Halén further explained.

Making it work
As far as testing and tyres go, BD Testing does both indoor and outdoor testing and is currently focusing on winter testing, winter tyres and studded tyres (conducting only product development tests for summer tyres). However, because the business is open all year, the winter tests are held in ice halls during the summer, Halén shared. As for snow testing, the indoor tests are conducted in Ivalo and Sweden.

However, most big tyre manufacturers conduct the majority of their tests themselves. Yet, that doesn’t stop a company like BD Testing. There are certain factors in testing that tyre manufacturers can’t carry out themselves and thus have to turn to the likes of BD Testing.

“For example, with road wear testing, it isn’t something they can do by themselves,” Halén asserted and added, “There are only five laboratories that can do that, and we are one of them. Similarly, indoor testing and snow testing is something they may not want to do – it’s a long way to travel and they don’t have the capacity to do so, which is where we come in.”

Indoor testing and outdoor testing
Speaking of indoor testing, it is the easier one to conduct over outdoor testing, Halén claimed. But since handling driveway in itself involves the car being built outdoors, there’s no choice over there, he informed.

What’s more, Halén asserted that usually they don’t test the same things indoors and outdoors – the two aren’t competing and are individual. “Their requirements too are different. But as for product development, some indoor testing is needed, like footprint or contact presser, which gives the designers a lot of information,” he enlightened.

BD Testing would, however, like to have its own indoor testing facility where tests can be conducted whenever needed. “Although, as of now, we have to rent for indoor testing, which can sometimes be fully booked,” Halén cited and added, “In fact, we want our own indoor testing facility that we can rent to other customers as well. However, it’s a huge investment and is too big for us at the moment.”

Objective and subjective testing
Another challenge that Halén spoke to us about, besides having an indoor testing facility, was in terms of manpower, where getting testing drivers is a challenge right now. When asked about the thought process behind selecting a testing driver (since the testing can be very subjective, from driver to driver), Halén highlighted that it’s the experience that plays a role. “And then, the drivers drive together and decide what works and what doesn’t. While these drivers do subjective tests, they, of course, also conduct objective tests. However, objective testing is easier, because you only have to know how to make the test,” he added.

Halén further said that with robots and automation, it’s possible that subjective testing will eventually get reduced in the future. “But in my opinion, with subjective driving, if a driver drives with a set of tyres, then we have a huge amount of information,” he pointed out. “Therefore, it’s a very fast way to have lots of information. If you try to have the same information with the help of machines, you’ll need several machines and it takes a long time. And if you need to analyse data, it takes a long time to develop a new methodology.”

A happy customer equals a successful company
While Halén gave us his clear visions in terms of BD Testing and the tyre testing industry as a whole, he also threw light on the company’s preparation for new regulations. “Additionally, we are focusing on what we are currently doing, targeting for higher quality and making our customers happy,” he expounded and added,
“Our strategy for that is based on the quality system we have. We have very close contact with our customers, so we try to understand what they need. Hence, I’m not trying to sell something to somebody if they don’t need it. Thus, I think our customers come to us themselves when they need something. So, ultimately, customer happiness has been our key to success.”

Cabot Corporation has received two 2026 Responsible Care awards from the American Chemistry Council for its performance in workplace safety and environmental management.

The company received the Waste & Water Stewardship Award and the Facility Safety Award at the ACC Responsible Care Conference in Fort Lauderdale, Florida.

Cabot was also named one of two finalists for the Responsible Care Initiative of the Year Award.

The Waste & Water Stewardship Award recognised the company’s handling of synthetic gypsum produced by the air pollution control system at its manufacturing site in Franklin, Louisiana. Cabot said it had identified a reuse application for the material in the cement industry, diverting nearly 15,000 metric tonnes of synthetic gypsum from landfill in 2025.

The company said the initiative helped it meet air emissions control requirements while reducing waste through the reuse of byproducts.

The Facility Safety Award recognised employee health and safety performance across Cabot’s US manufacturing operations, with nearly all of the company’s US manufacturing sites receiving the award based on their 2025 performance.

“We are honored to be recognized by the ACC for our leadership in advancing safety and sustainability performance,” said Jennifer Chittick, senior vice-president, safety, health and environment, and chief sustainability officer at Cabot.

“At Cabot, we believe our employees are our most valuable asset, and our long-standing commitment to safe working conditions, employee involvement in safety efforts, and workplace wellness is deeply embedded in our culture to ensure that all employees, contractors, and visitors return home safely each day.

“Furthermore, we remain committed to protecting the environment and reducing our impact through focused initiatives that drive lasting, positive change while strengthening our environmental performance in the communities where we operate.”

The ACC’s Responsible Care Awards programme recognises companies for environmental, health, safety and security performance, sustainability and chemicals management.

Cabot joined the ACC in 2010 and adopted the chemical industry’s voluntary Responsible Care initiative and Responsible Care Global Charter, aimed at improving health, safety, environmental and security performance across operations.

Hankook Tire, the exclusive tyre supplier to the FIA World Rally Championship (WRC), successfully completed the sixth round of the 2026 season, the Vodafone Rally de Portugal, where its Dynapro R213 rally tyre played a central role in managing the event’s punishing conditions. The tyre was engineered to absorb impacts from rough gravel and rocky terrain while delivering consistent grip and durability across the rally’s demanding stages.

Held from 7 to 10 May around Matosinhos in northern Portugal, the competition covered 23 Special Stages totalling approximately 345 kilometres. The surface began as soft, sandy gravel but progressively turned into sharp rocks and deeply rutted terrain due to repeated passes, making tyre durability and stability essential for performance. Hankook provided the Dynapro R213 in Hard and Soft compounds, allowing teams to balance high grip from the soft version with the hard compound’s resilience on changing surfaces.

After a fierce battle, Hyundai Shell Mobis World Rally Team driver Thierry Neuville secured overall victory, marking his team’s first win of the 2026 season. He took the lead in the closing stages and delivered a commanding performance to finish on the top step of the podium. In the Drivers’ Championship standings, Toyota GAZOO Racing’s Elfyn Evans leads with 123 points, followed closely by teammate Takamoto Katsuta on 111 points.

Throughout the event, Hankook operated a Brand World booth in the service park, featuring a motorsport heritage exhibition, racing simulators, branded merchandise and photo zones to enhance its premium global image. The 2026 WRC season now moves to Round 7, the FORUM8 Rally Japan on 28–31 May, a tarmac event on narrow mountain roads requiring precise steering and high-speed stability. Hankook continues to integrate WRC driving data into its R&D, advancing high-performance tyre technology as the exclusive supplier for all WRC classes since 2025.

DUNLOP Motorsport is all geared up for the 2026 ADAC RAVENOL 24h Nürburgring, scheduled to be held from 14 to 17 May 2026. At the legendary Nordschleife, the team will debut a Porsche 911 GT3 R bearing start number 17, marking the black-and-yellow car’s first appearance at the Eifel classic. A quartet of experienced drivers has been assembled to share the cockpit, including Frenchmen Julien Andlauer and Dorian Boccolacci, Belgian Alessio Picariello and Nordschleife specialist Nico Menzel.

A series of preparatory runs within the ADAC RAVENOL Nürburgring Endurance Series allowed the team to gather vital operational intelligence. Despite a rain‑affected delay to the opening round, the group managed to cross the line inside the top ten overall during its very first race. That outcome, combined with methodical calibration of the Porsche's suspension and aerodynamics, improved the squad's command of DUNLOP tyre behaviour under race conditions.

Unpredictable factors such as sudden showers, evolving asphalt grip and heavy lapped traffic frequently decide outcomes at the Nürburgring. Success therefore hinges on error‑free driving and disciplined strategic calls. The selected drivers bring precisely those attributes: Andlauer from his tenure in elite GT and prototype series, Boccolacci and Picariello from repeated Nordschleife campaigns, and Menzel from years of local expertise.

Several other entrants have also chosen DUNLOP rubber. Saugmotoren Motorsport will run the distinctive BMW Z4 E89, steered by Nordschleife veterans Ralf Schall and Christian Scherer. BLACK FALCON Team FANATEC, collaborating with Gran Turismo, enters a Porsche 911 GT3 Cup whose cockpit will be shared by Manuel Metzger, online personality Misha Charoudin and sim racers Steve Brown and Jimmy Broadbent. For spectators, the Boulevard area presents an interactive zone where Gran Turismo simulators offer virtual Nordschleife laps. A Porsche 962 C on loan from the Porsche Museum, winner of all five Supercup races in 1987 and that year's champion, will also be exhibited.

The ADAC RAVENOL 24h Nürburgring starts Saturday 16 May at 3:00 pm. Fans unable to attend can watch live via the official stream or on RTL Nitro. DUNLOP Motorsport also shares regular updates and content from the Eifel region through its social media channels.
