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.”

Hankook Tire has seen its summer tyre range validated this spring by three independent testing authorities. In the Auto Bild summer tyre test from the 10/2026 issue, the Ventus evo claimed overall victory in the 245/45 R19 size with a score of 1.1 and an ‘Exemplary’ rating, while the same model also won the Auto Bild allrad summer tyre test in the 255/45 R19 size from the 12/2026 issue, achieving a 1.2 score. Meanwhile, the Ventus Prime 4 earned strong praise in the AvD summer tyre test.

The Ventus evo’s success in the Auto Bild test began in qualification, where it secured a spot among 20 finalists from a field of 50, thanks in part to the second-best braking distances recorded. In the final dry handling assessments, it delivered the shortest braking distance and the highest average handling speed, while on wet surfaces it posted the fastest lap time on the aquaplaning circuit and the quickest speed in wet handling. The tyre also offered the best price-to-mileage ratio among all finalists.

In the separate Auto Bild allrad test, conducted in a size common for modern SUVs, the Ventus evo demonstrated strength both on and off the road. It led the field in wet braking and wet handling, achieved the highest traction on gravel and wet grass, and remained competitive on dry surfaces with low noise levels and short stopping distances. The test jury concluded it was the most convincing all-rounder for all-wheel-drive SUVs.

In the AvD summer tyre test, conducted with test specialist Tempotire in the 215/55 R17 size, the Ventus Prime 4 delivered a ‘Very good’ overall result. Its performance was particularly notable in wet conditions, where it recorded fast lap times, balanced handling and short braking distances while providing clear steering feedback and safe aquaplaning reserves. On dry roads, it offered reliable handling and strong rolling comfort. The tyre also earned high marks for sustainability, with production in Europe ensuring short transport routes and its EU label ratings reflecting modern construction. The jury highlighted its durability and cost efficiency, reinforcing Hankook’s reputation for delivering premium quality at a competitive price.

AZuR partner NEW LIFE initiative is set to host the inaugural Municipal Climate Dialogue on 22 April 2026, coinciding with International Earth Day. This free online forum, beginning at 10:00 a.m., is designed for municipal decision-makers to connect with experts and editors from the trade journal KOMMUNALWIRTSCHAFT. The event is structured around three focused 30-minute sessions, each dedicated to exploring proven strategies and concrete implementation methods for developing urban spaces that are both liveable and climate-friendly.

A central theme of this digital expert discussion is the critical role of sustainable building materials, with particular prominence given to high-quality recycled products derived from tyre rubber granulate. These solutions directly address the objectives of a climate-resilient city: reducing CO₂ emissions, minimising waste and conserving natural resources. Furthermore, the use of tyre rubber granulate obtained from end-of-life tyres aligns with the German Circular Economy Act (KrWG), which mandates public contracting authorities to prioritise recycled and durable materials. The dialogue will highlight how such products are instrumental in sustainable urban development.

Following a brief opening plenary, the event will feature three parallel 30-minute sessions, allowing participants to easily navigate between online rooms dedicated to distinct urban development topics. The morning begins at 10:10 a.m. with a focus on sustainable urban development, covering building protection through green roofs and photovoltaic systems, impact sound insulation for various construction types and vibration isolation. At 10:40 a.m., the discussion shifts to playgrounds, sports facilities and green spaces, addressing impact-absorbing flooring, playing field surfaces and green area reinforcement. The final session at 11:10 a.m. centres on transport and sustainable mobility, exploring traffic noise protection, recycled rubber asphalt for roads and traffic calming measures.

Products made from tyre rubber granulate offer municipalities a combination of ecological and economic advantages. Their use helps reactivate open spaces and reduce surface sealing, improving the urban climate through applications like water-permeable paving and rainwater-retaining green roof layers. These solutions are weather-resistant, slip-resistant and customisable while also providing long-term economic benefits due to their durability, low maintenance requirements and reduced need for repairs. Such high-quality recycled products are already being successfully implemented in urban development and municipal renovation projects nationwide.
