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.”

Pirelli is all set to conclude its tenure as the Official Tyre Supplier to the FIM Superbike World Championship at the Pirelli Spanish Round in Jerez de la Frontera. This weekend’s event not only wraps up a 2026 season dominated by Nicolò Bulega and Ducati but also ends a 23-season partnership that began in 2004. The journey has been marked by technological innovation, continuous development, close collaboration with teams and manufacturers and numerous sporting milestones.

For the Andalusian circuit, whose low-abrasion asphalt suits softer compounds, Pirelli has confirmed the softest rear options, already used at Estoril. WorldSBK riders will have the supersoft SCX and soft SC0 for practice, qualifying and races. The SCX, introduced last year as the E0126 development tyre, proved highly effective, helping Bulega claim all three race wins. The SC0 offers a valid alternative in cooler temperatures. The extrasoft SCQ, Pirelli’s softest tyre, will also be available for qualifying and potentially Sunday morning’s Superpole Race.

At the front, the soft SC1 and medium SC2 are both competitive at Jerez, as demonstrated in 2025 when Bulega took pole with the SC1 and won both full-length races with the SC2, while using the E0672 soft development tyre in the Superpole Race. Wet conditions will be covered by DIABLO Wet intermediate and DIABLO Rain tyres for both front and rear. For the WorldSSP finale, rear choices are the SCX supersoft and SC0 soft, with SC1 soft and SC2 medium at the front.

The Pirelli Spanish Round will decide the last two titles. In the debut FIM World Sportbike Championship, Spaniard David Salvador (Kawasaki) leads compatriot and fellow Kawasaki rider Xavi Artigas by 12 points, with two races and 50 points remaining. In the FIM Women’s Circuit Racing World Championship, Maria Herrera holds a 44-point advantage over fellow Spaniard Beatriz Neila. Both categories use Pirelli DIABLO Superbike tyres with the SC1 compound front and rear.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “The Pirelli Spanish Round will mark the final chapter in the long journey that began in 2004, when Pirelli joined the FIM Superbike World Championship as Official Tyre Supplier. Over the years, we have built a partnership that has seen us become not just a supplier but an active and strategic partner, contributing to the growth and development of the Championship. Before saying our final goodbyes, however, we still have one last round ahead of us, which we want to approach with the same determination and the aim of bringing a particularly positive season to the best possible conclusion. The results achieved, with new records set at virtually every circuit and in a wide variety of conditions, have gone hand in hand with intensive development work, carried out alongside the teams right up to the final race. For this last event, we have chosen to retain the softest rear options, the extrasoft SCQ and supersoft SCX, which have been used throughout much of the season. The extensive data collected over the years at Jerez, both during races and in testing, confirms that these are the most effective options for tackling a circuit characterised by low-abrasion asphalt.”
