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 confirmed the 2026 season of the Lamborghini Super Trofeo series will commence with its opening round in Florida from 18 to 20 March 2026. As the exclusive tyre supplier for this international championship organised by Italian supercar manufacturer Automobili Lamborghini S.p.A., Hankook will equip all competing Huracán Super Trofeo EVO2 cars with its ultra-high-performance Ventus racing tyre. This partnership, established in 2023, continues to see the Ventus tyre support Lamborghini vehicles under extreme conditions, withstanding speeds approaching 300 kmph while delivering exceptional grip, handling and durability across varied global climates.

The opening event, part of the North American series, is set to take place at the challenging Sebring International Raceway. This 6.0-kilometre circuit, constructed on the grounds of Hendricks Field Airport, presents unique difficulties with its combination of dedicated racetrack sections, airport runways and taxiways. The track surface itself adds another layer of complexity; concrete sections in particular place immense stress on tyres and become notably slippery when wet. Furthermore, the intense Florida sun can dramatically elevate track temperatures, making strategic tyre management a critical factor that could very well decide the race's outcome.

Despite these demanding conditions, the Ventus tyre is expected to perform reliably, showcasing Hankook’s advanced motorsports technology. Its robust construction provides the necessary heat resistance and stability for high-speed racing, reinforcing the global premium status of the Hankook brand through this strong collaboration with Lamborghini.

The 2026 Lamborghini Super Trofeo season will feature three continental series spanning North America, Europe and Asia, encompassing 10 countries and six rounds each. A key highlight for local fans is Round 4 of the Asia series, scheduled for 17 to 19 July 2026 at Inje Speedium in Gangwon Province. Following the conclusion of the regional championships, the top competitors will gather in Italy for the Grand Final from 24 to 25 October, where the ultimate world champion will be crowned.

DUNLOP has announced the launch of its BLUE RESPONSE TG, a new premium summer tyre developed for passenger cars and SUVs. Suitable for internal combustion, hybrid and electric vehicles, the tyre will be available in 99 sizes spanning 15 to 21 inches, series 40-65 with H, V and W speed ratings. Production takes place at a state-of-the-art facility in Türkiye, with European market availability scheduled for March 2026.

This launch represents a significant shift for the brand in Europe. BLUE RESPONSE TG is the first DUNLOP product developed under Sumitomo Rubber Industries (SRI) since it acquired the historic brand’s passenger car tyre rights in 2025. The tyre was engineered collaboratively by DUNLOP’s teams in Germany and Japan, drawing upon SRI’s established manufacturing and development capabilities.

The ‘TG’ designation stands for ‘Touring,’ underscoring the tyre’s ability to deliver long-distance comfort and efficiency while maintaining strong performance. A suite of new technologies ensures stability and control on both wet and dry roads. Impressive braking performance is a key feature, enhancing overall safety and driver confidence.

Central to the tyre’s capabilities is an intelligent three-zone rib design that efficiently channels water away from the contact patch. This promotes stability at higher speeds and unlocks reliable wet-weather grip during directional changes. A refined shoulder design features lateral grooves set at optimised angles. This enhances tread rigidity, reduces block deformation under load and ensures consistent force transfer when cornering and braking.

Durability is addressed through a new tread compound utilising longer, more resilient polymer chains. These resist abrasion and slow wear to extend mileage without compromising performance. To complete the package, a noise-reducing tread design links lateral grooves into continuous channels. This smooths airflow and dampens vibration, resulting in a noticeably quieter cabin environment and the composed, refined ride expected from the DUNLOP brand.
