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 has reported a dominant all-Ducati podium in Race 1 of the Dutch Round at Assen, the third fixture of the FIM Superbike World Championship. Nicolò Bulega extended his perfect start to the season with a seventh consecutive victory after a close contest with team-mate Iker Lecuona, who settled for second. Sam Lowes finished third, completing the manufacturer’s sweep. All three riders selected SC1 soft compound tyres for the front axle and SC0 soft rubber at the rear.

The weekend also highlighted the speed of Pirelli’s softest tyre options despite relatively cool conditions. During qualifying, Bulega established a new Assen lap record using the SCX supersoft rear, clocking 1 minute 32.144 seconds. That time shaved nearly half a second off the previous benchmark of 1’32.596, set by Lowes the prior year with the SCQ extrasoft compound. The other two Ducati riders on the front row, Lowes and Lecuona, also eclipsed the old record.

Elsewhere at the Dutch circuit, Jaume Masia won WorldSSP Race 1 on a Ducati, followed by Albert Arenas on a Yamaha and Tom Booth-Amos on a Triumph. Most of the Supersport field, including the top two, ran the SCX supersoft rear, while the third-place rider and nine others used the soft SC0; the SC1 was the universal front choice. In World Sportbike action, local rider Jeffrey Buis triumphed on a Suzuki, and the WorldWCR race went to Spain’s Maria Herrera on a Yamaha for her second win of the season. Both support classes employed DIABLO Superbike tyres with SC1 compound front and rear. Over the first two days, track temperatures varied from 16 degrees Celsius during early Superbike practice to 24 degrees for Supersport Race 1.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Despite the low temperatures, typical of Assen at this time of year, soft tyres were used in both WorldSBK and WorldSSP. The development work Pirelli has carried out over the years has enabled us to improve versatility and widen the operating temperature window of our tyres. As a result, the soft compounds were used with track temperatures slightly over 20 °C, delivering excellent performance. The new SCX supersoft tyre range, already used last year as development specification E0126, allowed Bulega in qualifying to improve the 2025 lap record by almost half a second, which was set with an even softer compound, the SCQ extrasoft. The SC0, on the other hand, starred in Race1: given the rather low temperatures, the riders preferred an already well-established solution to the development alternative F0298.

“In WorldSSP, both rear options – SCX and SC0 – proved equally competitive, as confirmed by the choices made by the riders on the podium.

“At the front, in both classes, the choice was unanimous: SC1, which ensures good grip and stability. For tomorrow’s Superpole Race, in dry conditions, we expect the SCX supersoft to be used at the rear, as it is more competitive over the 10-lap distance thanks to the extra grip compared to the SC0.”

TyreSafe, UK’s charity dedicated to raising tyre safety awareness, has launched a new seasonal campaign warning British drivers that spring rainfall poses a hidden danger often overlooked after the harsh winter months. The initiative, named ‘Drip Drip Drop – ‘Little’ April Showers’, focuses on the rising threat of aquaplaning as more vehicles return to roads that remain treacherously slick from sudden downpours.

National data shows that poor tyre maintenance is a leading cause of fatal incidents, with three quarters of car tyre defects linked to neglect. Research further reveals that at 70 miles per hour (approximately 112 kmph), worn tyres add 27 metres to the standard wet stopping distance, an increase of nearly 30 percent compared to the Highway Code baseline.

Incorrect tyre pressure compounds the problem significantly. Underinflated tyres struggle to channel water away, overheat more quickly and extend braking distances, while overinflated tyres reduce the tyre’s contact patch and compromise grip. Spring’s fluctuating morning and evening temperatures make pressure changes especially common during April.

Even tyres above the legal minimum tread depth can fail in heavy rain. Continental Tyres’ research found that at 50 miles per hour, tyres with 1.6 mm of tread required 6.9 metres longer to stop than new tyres with 8 mm tread, whereas those with 3 mm added 2.7 metres. Light rain after dry spells mixes with oil and debris, creating conditions where worn or incorrectly inflated tyres lose all steering and braking control.

With bank holidays, leisure travel and outdoor activities increasing during longer daylight hours, TyreSafe urges motorists not to assume the worst weather has passed. April showers arrive without warning, and the combination of winter road grime and sudden rainfall can turn a routine journey into a dangerous aquaplaning event within seconds. TyreSafe urges road users to embrace the simple ACT protocol: regular checks of air pressure, condition and tread depth.

Stuart Lovatt, Chair of TyreSafe, said, “April showers might sound harmless, but when they hit busy roads and combine with worn or incorrectly inflated tyres, the consequences can be devastating. Aquaplaning can happen in seconds and without warning. The research is clear – poor tyre maintenance dramatically increases stopping distances in wet conditions. That’s why we’re urging road users to ACT: check your Air pressure, inspect the Condition and monitor your Tread. A few minutes of checks could prevent a lifetime of consequences.”

Mitas has officially entered a three-year agreement with the National Tractor Pullers Association (NTPA), marking a significant commitment to one of North America’s most extreme motorsports. The partnership, set to run from 2026 through 2028, designates Mitas as the Official Agriculture Tire sponsor of the championship and Title Sponsor of the Mitas National Finals Pull-Off.

Tractor pulling represents a severe test of both raw power and engineering precision. Competitors pilot highly modified machines to drag a heavy sled down a dirt track, with resistance increasing incrementally until only the strongest and best-prepared vehicles remain. Success depends entirely on transferring massive horsepower to the ground under extreme conditions, where tire grip and consistency frequently determine the winner. The NTPA season includes over 60 events across United States, running from spring through early fall, with deep roots in the Midwest. As an official partner, Mitas will gain prominent visibility on and off the track while actively supporting the growth of the sport.

Central to this collaboration is the Mitas PowerPull tyre, a product specifically engineered for tractor pulling to convert raw engine output into winning performance. Designed to manage extreme torque and deliver maximum grip, the PowerPull functions as a slick tyre that permits teams to cut custom tread patterns based on track conditions and individual race strategy, providing a measurable competitive advantage.

The season will conclude with the Mitas National Finals Pull-Off, the championship’s premier event where the year’s top competitors vie for national titles. Scheduled for 18 and 19 September 2026, in Urbana, Ohio, the finals serve as the ultimate showcase of performance, innovation and passion. As title sponsor, Mitas deepens its connection to the pulling community by attaching its name to this marquee competition.

Roberta D’Agnano, Global Marketing Director Mitas at Yokohama TWS, said, “The collaboration with NTPA connects Mitas to two worlds where performance truly matters: tough daily work in the field and the most extreme competitive environments. Tractor pulling is the ultimate expression of what farmers face every day – delivering power to the ground, staying consistent under pressure and performing when limits are pushed.

“Performance isn’t just about winning on the track – it’s about delivering results when it counts most, whether in competition or on the farm. In tractor pulling, every component is tested to the extreme, just as it is in real agricultural operations. That’s why we feel a strong connection with this community. The NTPA community embodies passion, resilience and a nonstop drive to push boundaries; values that are core to the Mitas brand. We’re excited to be part of this world, learning from these extreme conditions and turning that knowledge into tyres that perform where it matters most for farmers and pullers alike.”
