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.”

Ainscough Crane Hire, UK’s largest crane hire business, has significantly deepened its collaboration with Michelin by placing its entire tyre management operation in the hands of Michelin’s Connected Solutions (CXS) division. What began in 2023 as an arrangement focused on the company’s truck tyres has now evolved into a comprehensive, long-term partnership covering the full spectrum of the operator’s fleet.

Operating from 30 sites nationwide, the agreement encompasses more than 350 Liebherr cranes, a substantial number of which are 16-wheelers, alongside 135 trucks and trailers and 199 support vans. Included within this are 40 Scania heavy goods vehicles dedicated to heavy haulage. CXS now coordinates the supply of roughly 1,000 tyres annually through a national network while also providing detailed sustainability reporting to support Ainscough’s environmental goals.

The extension of the partnership was reinforced by a successful benchmarking trial, which demonstrated that Michelin’s X Multi truck tyres delivered three times the lifespan of a leading competitor. These fitments now equip the majority of the haulage fleet. Michelin is also introducing its advanced X Crane 2 tyres across the heavy crane fleet as existing rubber is replaced. These tyres offer a new tread pattern for enhanced grip and braking, alongside a higher load capacity that permits an additional 800 kilogrammes per tyre at highway speeds. Certified testing also shows they are more than 13 percent more fuel-efficient than their main premium rival due to reduced rolling resistance.

Sustainability remains central to the arrangement. Ainsworth makes full use of Michelin’s multi-life tyre policy for its trucks and ballast trailers. Casings are regrooved once tread depth diminishes, then later retreaded at Michelin’s Remix facility in Stoke, with the option for further regrooving. The company’s Mercedes-Benz service vans are fitted with the adaptable Michelin Agilis CrossClimate tyre.

Supporting this comprehensive operation is Fraser Greer, Key Account Manager at CXS. Ainscough Crane Hire continues to serve a wide array of sectors including infrastructure, defence, energy and telecommunications, cementing its role as a key contributor to the UK’s built environment.

Chris Britton, Head of Operations Support, Ainscough Crane Hire, said, “Michelin has become our latest highly valued strategic supplier relationship. Being the number one operator in our field, we only go with trusted and number one brands as our suppliers. The fuel savings of GBP 130 per 10,000 km will save us GBP 100,000s across the lifetime of the machines and reduce their environmental impact. Likewise, the increased load factor of the fitments and the 20 percent improvement in braking distances really impressed us. It means safety margins will increase, and safety is at the heart of everything we do.

“As a business we aren’t looking for the cheapest deal, but the best value. We are receiving a world class service from Michelin. It has streamlined procurement and helped us forecast tyre costs better; it has delivered the right products in the right place ensuring maximum uptime for our cranes; we have a ‘best way of working’ when it comes to protocols and tyres being fitted at our sites; and we have full traceability of each tyre and an insight into its environmental impact.”

The Australian Grand Prix delivered a thrilling season opener, with Pirelli’s tyre compounds playing a central role in the strategic narratives that unfolded. George Russell claimed victory for Mercedes, leading home rookie teammate Kimi Antonelli in a one-two finish. Charles Leclerc secured third place for Ferrari, completing a podium that showcased a mix of experienced talent and fresh faces.

The race began with immediate drama as the latest generation of Formula 1 machinery hit the track. Early interruptions prompted by several brief Virtual Safety Car periods led Mercedes to bring its drivers into the pits sooner than perhaps anticipated. Both Russell and Antonelli switched from the medium to the hard compound, committing to a successful one-stop strategy that ultimately paid dividends. Overtaking was plentiful throughout the field, contributing to a highly entertaining spectacle. However, the home crowd was left disappointed as local hero Oscar Piastri failed to even start the race. His McLaren teammate, Lando Norris, managed a fifth-place finish after adopting a two-stop approach, while four-time champion Max Verstappen, who started from the very back of the grid, fought through to sixth place using the same two-stop tactic.

Despite the varied strategies, the top four finishers all committed to a solitary pit stop. While the Mercedes pair and Leclerc celebrated on the podium, Lewis Hamilton crossed the line in fourth for Ferrari, just missing out on a top-three finish. His result, combined with Leclerc’s podium, places the Scuderia second in the early Constructors' Championship standings. The event was blessed with warm and sunny conditions, with temperatures remaining stable around 26 degrees. The paddock now quickly shifts focus to the upcoming Chinese Grand Prix.

In the Formula 2 curtain-raiser, Nikola Tsolov made history by becoming the first Bulgarian winner in the category's history. Driving for Campos Racing, he led home Rafael Câmara and Laurens van Hoepen. The race was marred for Rodin Motorsport as teammates Martinius Stenshorne and Alex Dunne collided, ending their afternoon. All three podium finishers employed an identical pit strategy, pitting on lap nine to exchange their starting Supersoft tyres for the Soft compound, a move that propelled Tsolov to the top of the drivers' standings.

Campos Racing extended its winning ways into Formula 3, where Ugo Ugochukwu took the chequered flag. Freddie Slater finished second, placing him second in the championship behind Ugochukwu, while Taito Kato completed the podium in Melbourne after benefiting from post-race time penalties applied to two rivals.

Dario Marrafuschi, Pirelli Motorsport Director, said, “As we expected yesterday, the first Grand Prix of the season was won with a one-stop strategy. The Mercedes drivers crossed the finish line in the same positions in which they started on the grid, adopting an identical strategy. The final stint on the hard tyres could be extended compared to Saturday's forecasts thanks to limited degradation, which allowed the drivers to complete the race with the same set they had during the VSC. Those who opted for two stops took advantage of the neutralisations to change fresh tyres without risking losing too many positions, in some cases even using the Softs for a final sprint.

“All three compounds therefore proved useful during the race, with the C3 capable of supporting stints of up to 46 laps thanks to its consistency. The left front was the tyre most affected by graining, though without causing excessive wear or degradation issues. We are, however, at the beginning of a new technical cycle and on a track that is not particularly demanding on tyres. With the development of the cars and the arrival of more challenging circuits, we expect inevitable changes in tyre management. Tyres remain one of the many variables teams will have to consider among the numerous innovations of this season.”
