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.”

Michelin has formed a technical and sporting alliance with Segway as the Segway Dakar Rally Factory Team prepares to enter the 2028 Dakar Rally aboard an entirely new, fully electric racing motorcycle. Acting as the team's official tyre supplier and technical partner, Michelin will be involved from the project's very first stages, supporting Segway throughout development.

Segway, drawing on its electric mobility background, is pursuing a demanding engineering goal: designing a brand-new 100 percent electric racing motorcycle built to survive the Dakar Rally's punishing conditions. The event will act as a live testing environment where both partners can subject their newest innovations to extreme demands and probe fresh territory in performance and electric mobility.

The partnership is being officially sealed at EICMA 2026 in Milan, Italy, a major international motorcycle industry showcase, where representatives of both firms will sign an agreement confirming their joint dedication to the Dakar 2028 venture. Cooperation will reach far past race-tyre supply, with engineers from both sides collaborating to weave rally-raid requirements into Segway's future electric machine.

Michelin will lend its off-road and rally-raid know-how plus tyre and Bib Mousse puncture-prevention expertise, initially guiding Enduro and Desert tyre selection and advising on Bib Mousse choice, fitting and use. Joint workshops will unite Michelin Motorsport specialists with Segway engineers, gathering data under rally-raid-representative conditions to steer later tyre optimisation. With Michelin's Dakar record since 1983 and 40 victories behind it, a joint testing programme will adapt tyres progressively to the motorcycle's final specifications and demands.

Cyriaque Echevin, Michelin Off-Road Tire Marketing Director, said, “True to its pioneering spirit, Michelin is delighted to support the Segway Dakar Rally Factory Team in this particularly ambitious project. Taking on the Dakar Rally with 100 percent electric motorcycles represents an exciting technological challenge, bringing new parameters that we will need to factor into our development work. Our role will extend far beyond supplying tyres: our teams will work alongside Segway’s engineers from the earliest stages of the project, sharing our rally-raid expertise and contributing to the development of the new motorcycle. The Dakar Rally provides an exceptional testing ground for pushing technological boundaries through close collaboration with our partners.”

Pirelli has chosen a softer trio of compounds for the São Paulo Grand Prix at Interlagos, naming the C3 as Hard, the C4 as Medium and the C5 as Soft. That is one step softer than a year ago, when the weekend followed the Sprint format. The race closes the long back-to-back swing through the Americas at the José Carlos Pace circuit.

Fresh asphalt laid during the year between Turns 3 and 5, and again between Turns 8 and 9, could shift grip levels and change how the track evolves. Longer runs may be affected in particular. Across the three free practice sessions, teams will study the new surface and its influence on wear and degradation.

Last year, degradation was a decisive technical theme in São Paulo. Graining came in milder than feared, but the C2 Hard of that weekend tended to slide, and the C3 and C4 wore heavily while still supporting competitive stints. A two-stop race proved the strongest approach.

Interlagos produces broadly average lateral forces overall, mixing fast corners with long straights, so the layout is not especially punishing. Loads fall fairly evenly between front and rear axles. Overtaking chances are plentiful, giving strategists room to manoeuvre, yet degradation management has usually decided who performs best, making the trade-off between one-lap speed and long-run durability central to trackside work.

Rain and sharp temperature swings are familiar at this venue given its calendar slot, so Intermediate and Full Wet tyres may again feature. In 2025, Medium and Soft dominated a wide spread of strategies, with most teams choosing two stops after an early neutralisation triggered pit visits. Pit windows differed by driver, opening gaps that aided overtaking; only two drivers stopped once, and Hard tyres appeared in just a few brief stints.

Interlagos has staged 42 Grands Prix, 37 of them titled the Brazilian Grand Prix between 1973 and 2019 before the São Paulo name returned in 2021. Michael Schumacher leads with four wins, while Sebastian Vettel, Lewis Hamilton and Max Verstappen hold three each; Ferrari and McLaren share nine team victories. The special Podium Cap, designed by Denis Dekovic for Pirelli Design and inspired by Brazil's 1958 blue football shirt with a jaguar-pattern finish, is on sale via Pirelli's e-commerce platform.

Dunlop Motorcycle Europe is celebrating a successful conclusion to the 2026 Campeonato de España de Superbike (ESBK) campaign, with five of its equipped riders securing titles at the Sunday finale at Circuito de Jerez Ángel Nieto. The brand claimed five of the series' eight championships, four of them in open-tyre competition classes, after a tightly contested season spanning Spain and Portugal.

The ESBK's open-tyre rules in several classes give Dunlop a direct benchmark against competing manufacturers. The company backed riders throughout the year in Superbike, Supersport, Supersport 300, Superstock 600, Superstock 1000 and Pre-Talent. Four of those classes allow any tyre brand, while Dunlop is the sole supplier for Supersport 300 and Pre-Talent.

The Superbike, Superstock 600 and Pre-Talent crowns all remained undecided going into Jerez. Honda Laglisse's Javier Palomera clinched Superbike ahead of Dunlop-backed Ivo Lopes of BMW Easyrace Team, runner-up in the open-tyre class; the same squad also took Superstock 1000 through Mauro González. José Luis Armario won the last Superstock 600 race of the year, and in Supersport, Team Speed Racing's Marcos Ludeña placed second with Team Honda Laglisse's Yeray Ruiz third, giving Dunlop two of three open-tyre podium slots. In the Dunlop-only classes, Marc Vich took Supersport 300 and the Kawasaki Ninja Spirit Trophy, while Marcos Vinagre won Pre-Talent at Jerez, leading an all-Dunlop podium alongside Javier Vigueras and Jose Luis Cagigas.

Dunlop's ESBK programme uses its KR racing slick line, covering both development and catalogue specifications, with wet tyres also available. Data from real race weekends helps the brand validate new products before they reach other championships and track-day use. Dunlop's racing footprint also takes in the Campionato Italiano Velocità, which produced six more Dunlop champions in 2026, and the FIM Endurance World Championship, where a fresh multi-year deal makes Dunlop the sole supplier to the Superstock and Production Trophy classes.

Roberto Finetti, Marketing Manager, Dunlop Motorcycle Europe, said, “It's great to see Dunlop-equipped riders achieve such strong results in the 2026 ESBK season, with championship titles secured across multiple categories and two all-Dunlop podiums in Supersport 300 and Pre-Talent. We're incredibly proud of what our riders and teams have achieved this season and of the role Dunlop has played in their success. These results are a testament to their dedication and hard work throughout the year. Congratulations to all the newly crowned champions.”

Tegeta Green Planet, in partnership with the United Nations Development Programme (UNDP), organised an information and practical campaign titled ‘Don’t Throw It Away, Hand It In’ in Poti. Held on 29 October at a Tegeta Motors branch, the initiative sought to strengthen environmental responsibility and promote proper management of specific waste streams.

The campaign targeted local residents, vehicle owners, drivers and private sector representatives, encouraging their active involvement in waste management. Attendees learned about the environmental impact of automotive waste and correct disposal methods. A dedicated collection point at the branch allowed residents to hand in end-of-life tyres, used batteries and waste oils, offering a practical way to contribute to environmental protection through everyday actions.

A significant focus was placed on raising awareness about the Extended Producer Responsibility (EPR) system, including the role of EPR organisations, collection and subsequent management of specific waste streams and importers’ legally established obligations. Symbolic gifts encouraged participation. Tegeta Green Planet and UNDP continue to implement regional environmental campaigns and educational initiatives aimed at raising public awareness, fostering responsible waste management and promoting circular economy principles.
