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.”

Sun Auto Tire & Service, one of the largest independent tyre and automotive service providers in US, has entered into a new sponsorship agreement with Ty Gaynor Motorsports, backing driver Ty Gaynor as he takes on the NHRA circuit in both Top Dragster and Super Stock categories. This alignment brings together two entities that prize performance, precision and consistency – qualities that are essential under the hood and behind the wheel. Sun Auto’s branding will appear on Gaynor’s race vehicles throughout the season, with the company’s nationwide network of over 575 locations symbolically travelling alongside him as he competes across the country.

At just 18 years old, Gaynor represents a third generation of drag racing heritage, having climbed from Junior Dragsters to secure his first NHRA national event victory in 2025 at the Dodge NHRA Nevada Nationals. That landmark Top Dragster win featured a nearly flawless reaction time and a run closing in on 200 mph (approximately 322 kmph). Company leaders describe the sponsorship as a natural outgrowth of Sun Auto’s deep roots in automotive service and its enduring commitment to high-level performance.

The 2026 season will see Gaynor continue his campaign in both Super Stock and Top Dragster competition, with his first race scheduled for the upcoming weekend. Through this partnership, Sun Auto reinforces its connection to the precision and dedication that define success both on the track and in the service bay.

Gaynor said, "Growing up around my family's shops that are now part of the Sun Auto Network, it feels like everything's come full circle having that logo on my cars. What started as family is now a network of more than 575 locations across the country."

Matthew Loos, Chief Marketing Officer, Sun Auto Tire & Service, said, "Whether it's in the shop, in the pits or on the track, consistency, precision and performance matter.”

Dunlop Motorsport marked its competitive debut on the Nürburgring Nordschleife with a strong top-10 finish, underscoring the potential of its advanced tyre technology. Central to this effort was the use of Dunlop tyres, integrated with the innovative Sensingcore system developed by Sumitomo Rubber Industries. This proprietary technology transforms the tyre itself into a smart sensor, delivering real-time data on critical parameters such as wear, pressure, wheel load and track conditions without requiring additional hardware. By enhancing both safety and strategic decision-making, Sensingcore enables early detection of issues like loose wheel nuts and allows for optimised pit stops, proving its value under the extreme demands of the ‘Green Hell’.

Behind the wheel of the black-and-yellow Porsche 911 GT3 R, drivers Nico Menzel and Dorian Boccolacci delivered a determined comeback. After a challenging qualifying session left them in 24th place due to ill-timed yellow flag periods, Menzel wasted no time, surging to 18th by the end of the opening lap. Boccolacci then took over, extracting the full potential of the new Dunlop slicks with consistently fast lap times. A well-executed team strategy propelled the duo into the top 10 before the race’s midpoint. Although the leading pack had built an insurmountable gap by then, preventing a podium challenge, Boccolacci brought the car home in ninth place overall after four hours of racing.

The event served as a crucial development test for both tyre technology and Sensingcore under real-world conditions, highlighting its promise for future motorsport and production applications. Dunlop Motorsport will continue its preparation at the next Nürburgring Endurance Series round, the 57th Adenauer ADAC Circuit Trophy on 11 April 2026, as part of its buildup to the ADAC RAVENOL 24h Nürburgring in May.
