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.”

Scandinavian Enviro Systems (Enviro) has received court approval to initiate a formal company reorganisation process. The Gothenburg District Court granted the application submitted by the company on 26 February 2026, with the procedure applying specifically to the parent entity. This type of restructuring is initially granted for three-month intervals, with the first period now commencing. Johan Sölveland from Ackordscentralen has been appointed to oversee the process as reorganisation administrator.

The decision to seek this legal protection was driven by acute liquidity challenges. A primary factor was the financial strain from unfavourable contractual agreements tied to the Infiniteria joint venture. Additionally, costs stemming from disputes related to a domestic plant project, combined with ongoing arbitration proceedings, have hindered the company’s ability to attract new financing. Compounding these issues, the operational facility in Åsensbruk has not been generating sufficient cash flow to offset these pressures.

Through the reorganisation, the company aims to create necessary breathing room to negotiate with creditors and develop a sustainable long-term financial framework. Management is actively engaged in discussions with both suppliers and customers to maintain normal business operations throughout this period. A detailed plan outlining the proposed structural changes to the business will be presented in due course.

The board has confirmed that current liquidity is adequate to sustain operations for the initial three-month phase of the reorganisation. Efforts are underway to arrange additional funding within this timeframe, with the objective of presenting a fully financed restructuring plan that ensures the continuity of the business.

Mitas has launched TERRAGUARD, a new generation of VF implement radial tyre, at the Commodity Classic in San Antonio, Texas, held from 25 to 27 February. This latest addition to the Mitas portfolio addresses the pressing demands of contemporary agriculture, including the need to accommodate larger, heavier implements, improve operational efficiency and prioritise soil health.

Engineered for high-capacity applications, TERRAGUARD is designed to bear significant loads while operating at reduced inflation pressures. This allows the tyre to conform to ground contours, ensuring stable handling, a consistent footprint and reliable performance across uneven terrain during both fieldwork and road transport. The tyre’s square shoulder design maximises the contact patch to boost stability, while reinforced sidewalls improve lateral stability, especially when traveling on roads.

A key attribute of the TERRAGUARD is its focus on efficiency. Its advanced VF radial construction and optimised tread geometry lower rolling resistance, facilitating smoother operation and better energy conservation. Furthermore, the tyre’s ability to spread weight evenly over a larger surface area reduces soil compaction, preserving soil structure and enhancing productivity during extended work periods.

The distinctive sawtooth tread pattern complements this by balancing rolling efficiency with controlled traction, minimising vibration and ensuring dependable performance across diverse cultivation tasks and conditions. By integrating high load capacity, operational efficiency and soil protection into one solution, the Mitas TERRAGUARD meets the needs of modern farming. Initially available in sizes VF 280/70R15 TL IMP 140D and VF 295/75R22.5 TL IMP 158D, the range is set to expand with additional sizes in the future.

Roberta D’Agnano, Marketing Director MItas at Yokohama TWS, said, “Modern agricultural operations require implement tyres that do more than simply carry weight. With TERRAGUARD, we combined advanced VF technology with an innovative tread design that actively supports efficiency and soil protection, helping farmers boost productivity in demanding applications. Presenting this product for the first time at Commodity Classic is especially meaningful for us, as the US market is at the forefront of large-scale, high-load farming applications. TERRAGUARD has been developed to meet the specific demands of American farmers, making this event the ideal platform for its global debut.”
