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.”

Maxxis has expanded its mountain bike lineup with two major innovations, one addressing the demands of modern cross-country racing and the other exploring entirely new terrain in wheel design. The brand introduces the Aspen AT, a tyre built for rougher and more variable XC courses, alongside a pioneering family of 32-inch mountain bike tyres.

The Aspen AT draws from the trusted Aspen family’s speed but adds a revised tread profile that boosts control and confidence on uneven ground. It sits between pure racing tyres and aggressive trail models, giving riders a single option for the varied demands of today’s XC and down-country riding. While the Aspen AT addresses the present, Maxxis looks further ahead with its new 32-inch platform. Larger wheel diameter improves rollover capability, traction and high speed stability on rough trails, offering a fresh choice for those who want to keep momentum and smooth out feedback without replacing current wheel sizes.

The initial lineup includes Aspen ST, Aspen and Aspen AT tread patterns, with Forekaster and Dissector versions following in the third quarter. Key features of the Aspen AT include a fast-rolling XC tyre with broader all-terrain capability, a revised tread for better grip in rough sections and construction suited to modern racing disciplines. The tyres deliver increased rollover for a smoother ride over obstacles, improved efficiency on rough surfaces and a larger contact patch that translates into greater stability and grip.

By adding the Aspen AT and introducing the 32-inch tyre family, Maxxis continues to lead the evolution of mountain biking, supporting riders from competitive starts to the very edge of what is possible on two wheels.

Goodyear is all set to launch the new Kwik Fit British Touring Car Championship (BTCC) season this weekend at Donington Park’s National circuit. A 21-car grid marks the beginning of a campaign defined by a changed race structure, one that puts a stronger focus on how teams manage their tyres and prepare for each session rather than raw pace alone.

For the Donington rounds, competitors will receive four sets of the standard Goodyear Racing Eagle Medium tyre plus one set of the softer option compound. Throughout the season, every event will include both the standard tyre and one set of the option rubber, which must be used in at least one of the three races held over the weekend.

The most significant strategic shift comes from the revised weekend schedule. There is now only a single free practice session before qualifying and the newly introduced Race to Pole on Saturday. This compressed timeline is expected to reshape tyre strategies dramatically, rewarding those who can best adapt to limited track time.

In wet conditions, teams can turn to the Goodyear Racing Eagle Wet tyre, designed with a tread pattern that clears standing water to deliver grip. Beyond the BTCC, Goodyear Racing Eagle tyres will also be in action this weekend at the FIA World Endurance Championship’s Six Hours of Imola, as well as in the NASCAR Cup Series and the NASCAR O’Reilly Auto Parts Series races at Kansas Speedway.

Michael Butler, Goodyear’s BTCC event leader, said, “This season, teams will have more preparation to do, but less time to do it in. The changes put a lot of pressure on drivers to make the most of free practice, as it’s the only real opportunity to understand how the tyres are working before dialling in a setup that needs to perform in qualifying and the Race to Pole.

“Typically, teams will add a degree or even a degree and a half of extra negative camber for qualifying to maximise one-lap performance. However, with parc fermé conditions in place between qualifying and the Race to Pole, what will make a strong strategy is finding a setup that works across both sessions, or choosing to favour one and accepting a compromise in the other. That’s where tyre management and understanding how the different compounds behave will be key.”

Kumho Tire USA has kicked off the 2026 Formula DRIFT PRO Championship season with a strong statement, as their driver Jack Shanahan secured third place in the opening round. Competing on Kumho’s Ecsta V730 tyres, Shanahan piloted an E82 BMW that was assembled in only 16 days. His podium finish demonstrated remarkable skill and precision throughout each battle, setting a positive tone for the season ahead.

After earning second place in qualifying, Shanahan moved confidently through the main competition, defeating Rudy Hansen, Jeff Jones and Aurimas Bakchis in successive rounds. However, when engine troubles arose during his Top Four matchup against Fredric Aasbo, Shanahan made the difficult but honourable decision to withdraw rather than risk spilling oil onto the track. This unfortunate mechanical failure also denied spectators the potential excitement of a final round showdown between Jack and his brother.

Shanahan first joined the Formula DRIFT PRO Championship in 2025, quickly establishing himself as a serious competitor. His rookie season was exceptional, as he finished sixth overall and earned Rookie of the Year honours while supported by Kumho tyres. Now in 2026, he aims to build on that momentum with clear goals of reaching more podiums and contending for the championship, steadily proving himself among the world’s elite drifters.

Ed Cho, CEO, Kumho Tire USA, said, "We are absolutely thrilled with Jack Shanahan's impressive performance on the Streets of Long Beach, where he put our Ecsta V730 tyres to the ultimate test at the highest level of competitive drifting. His podium finish is a powerful testament to the exceptional performance and unwavering reliability of KUMHO tyres, and we are excited to have him as a returning driver for the 2026 season."

Shanahan said, "After building an all-new car for Formula DRIFT in just 16 days, we are incredibly grateful to have secured third place in round one, and KUMHO was a huge part of our success. I had every confidence in the KUMHO Ecsta V730 tyres and they performed flawlessly – providing the grip and consistency we needed for every battle on a highly technical and challenging course."

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.
