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 enters the 2026 FIA European Rally Championship (ERC) season as the defending Tyres Manufacturer champion, with the opening round taking place from 17 to 19 April on the demanding asphalt roads of Rally Sierra Morena in Andalusia. A total of 62 crews will gather for the event, and more than 30 of them are expected to fight for the initial points of the European title race. The challenging route features 203.80 timed kilometres spread across 13 special stages, setting the scene for a competitive weekend.

To equip its teams for this gruelling asphalt challenge, Pirelli has prepared a selection of tyres from the P Zero range, specifically the hard RA5C and soft RA7+ compounds for dry conditions, complemented by the Cinturato RWD for wet weather. Among the leading contenders using Pirelli tyres are Andrea Mabellini, who secured third place in the overall championship last year and will drive a Lancia Y HF, along with reigning Italian champion Giandomenico Basso and Teemu Suninen, both piloting a Skoda Fabia RS.

Beyond the main European championship entries, Pirelli also serves as the sole supplier and technical partner for the M-Sport Fiesta Rally3 Trophy, now in its third season. This initiative has attracted 11 crews to Rally Sierra Morena, further highlighting Pirelli’s broad involvement in the event. The tyre allocation rules specify that drivers in RC2, RC3 and RGT categories receive 16 tyres, while those in RC4, RC5 and RC6 are allocated 12.

For crews taking part in Qualifying, the tyres used during that session count towards the overall allocation. However, tyres used during Free Practice and the Shakedown are not included in the total. With a strong field and Pirelli’s comprehensive technical support, the 2026 season opener promises intense competition on the Andalusian stages.

Continental has responded to the changing landscape of modern gravel riding by adding a new 50 mm version of its Dubnital tyre to its product range. This tyre model first proved itself in fast paced cross country racing, where it became known for combining impressive rolling speed with dependable handling. Before this launch, gravel riders had already embraced the larger 55 mm Dubnital, and this slimmer 50 mm option now allows Continental to better serve those competing on increasingly aggressive and technical gravel courses.

Designed for surfaces ranging from dry to damp, including rocky trails, hardpack and medium loose dirt, the Dubnital 50 mm features a carefully arranged tread. Its smooth centre section keeps straight line riding efficient, while the raised shoulder knobs dig in to deliver strong braking traction and steady cornering when the ground turns rough or unpredictable. The tyre also incorporates Continental’s latest Tubeless Ready and hookless compatible designs, ensuring it works properly with current wheel systems without sacrificing the control or performance the Dubnital name stands for.

As gravel race routes become faster, rougher and more complex, this new 50 mm tyre is quickly becoming a top choice for cyclists seeking a genuine balance between speed, stability and toughness. For cross country and down country riding, the Dubnital remains a quick option for light mixed terrain and hardpack surfaces. But for gravel applications specifically, the 50 mm size unlocks a more aggressive setup, giving riders the confidence to handle tougher courses and unpredictable trail conditions.

Rosa Klöser, 2024 Life Time UNBOUND Gravel 200 winner and Continental Tires ambassador, said, “For me, the Dubnital 50 mm is one of the most anticipated tyres in gravel right now. Considering the clearance of most gravel bikes, adding a 50 mm Dubnital will make a lot of gravel fans very happy – including myself. The tyre inspires a huge amount of confidence, especially in corners where you can really maximise your speed thanks to its incredible grip and braking control. But what stands out for me is its versatility – it’s not just for technical gravel! It’s a fast, reliable all-rounder for riders who want extra comfort, grip and durability without sacrificing speed.”

Alexander Haenke, MTB and Gravel Product Manager, Continental Tires, said, “With the introduction of the Dubnital 50 mm, we are removing the boundaries between mountain biking and gravel once and for all. The Dubnital already surpassed its predecessor, the Race King, and now confidently straddles the line between the gravel and MTB segments. In this 50 mm dimension, it hits a distinct sweet spot for technically demanding off‑road races such as Traka, The Rift or Badlands. The Dubnital 50 mm delivers its well‑proven off‑road performance paired with low rolling resistance, high puncture protection and low weight — a trend born in the racing scene, now available to everyone.”
