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.”

The Dunlop RoadSmart IV has emerged as the top performer in the latest road tyre test conducted by renowned German publication MOTORRAD. This premium sport touring tyre received high marks for its outstanding handling characteristics and its ability to deliver balanced performance regardless of weather or road surface conditions. The victory adds to Dunlop’s growing list of independent testing successes this year, following a similar overall win for the SportSmart mk4 in an earlier sport tyre comparison.

In the test, MOTORRAD fitted three road focused tyres to a BMW R 1300 GS using the specific sizes of 120/70 R19 at the front and 170/60 R17 at the rear. The RoadSmart IV secured first place overall in the road tyre category, demonstrating class leading wet performance while also tying for the best results in the dry sub category. This achievement marks the second time in half a decade that this particular tyre has claimed top honours in a MOTORRAD test.

Testers were especially impressed by the tyre’s precise dry handling and the clear feedback it provides to the rider. They observed that the RoadSmart IV turns in more easily than its rivals, making it highly recommended for motorcycles that tend to have sluggish steering behaviour. On the BMW test bike, the tyre felt stable rather than unsettled, excelling with high cornering speed, solid grip at maximum lean angle and extremely accurate feedback. In wet conditions, the tyre offered easy manoeuvring ability through fast cornering sequences, with its precise communication clearly signalling the limits in a user-friendly manner.

MOTORRAD summarised the RoadSmart IV as an incredible all-rounder that combines excellent handling with top performance in all conditions, even suggesting that riders on a GS could use it to annoy superbike riders. Thanks to its strong showing on both dry and wet surfaces, the tyre also earned the magazine’s coveted Kauftipp, or purchase recommendation, award.

Roberto Finetti, Marketing Manager, Dunlop Motorcycle Europe, said, “This result for RoadSmart IV reinforces our goal to deliver a perfect balance of outstanding dry performance and exceptional wet grip and precise handling, even after several thousand kilometres. We’re proud to see it recognised once again as a benchmark in the sport touring segment.”

Scandinavian Enviro Systems AB (publ) has announced that its representatives on the Board of Directors of the joint venture entity, Infiniteria Europe Sàrl, namely Ewa Björling and Fredrik Aaben, have made the decision to vacate their respective director positions. This move follows prior communications from Enviro regarding a broader strategic shift in its relationship with the joint venture.

Earlier, Enviro had already disclosed that it was initiating a corporate reorganisation process, which included the termination of the various agreements that had previously defined and governed the working relationship and collaborative framework between Enviro and Infiniteria. This fundamental restructuring of their partnership set the stage for further complications, as disagreements began to surface between Enviro’s board members and the other directors serving on the Infiniteria board.

Specifically, the differing viewpoints between these two groups centred on critical matters related to corporate governance standards and the internal functioning of the board itself. Due to the emergence of these unresolved conflicts, combined with the ongoing dissolution of their formal cooperation agreements, Björling and Aaben concluded that stepping down from Infiniteria’s board of directors was the necessary course of action, leading to their formal resignations.

MESNAC played a central role at the 2026 China Rubber Annual Conference, held in Qingdao from 24 to 27 March by the China Rubber Industry Association. On March 24, the Enlarged Meeting of the Rubber Machinery and Molds Branch took place, gathering key figures such as Deputy Secretary-General Zhu Hong, Branch Secretary-General Jiang Xin and Branch Chairman Guan Bingzheng, who also serves as MESNAC’s Chairman and President. Representatives from leading enterprises and governing units discussed the industry’s 2025 performance, ongoing difficulties and 2026 trends. The session was hosted by Zhou Chuanhai, General Manager of MESNAC Union Technology Co., Ltd.

Bingzheng pointed out that the rubber machinery and moulds industry managed to achieve positive overall growth in 2025 despite facing numerous difficulties. Rubber machinery exports rose notably even under adverse conditions, while the mould sector continued its gradual upward climb. He also noted that the industry has moved away from simply pursuing larger scale and is now prioritising higher quality and better performance.

With 2026 marking the start of the 15th Five Year Plan period, which is crucial for turning China from a large rubber producer into a powerful rubber nation, he laid out three main directions. One is embracing green practices, smart technology and global market expansion. Another is keeping pace with tyre manufacturers moving overseas to enable shared global growth. The third is focusing on new energy tire needs and artificial intelligence upgrades to push the industry towards high end transformation.

On March 26, at a forum themed Digital Empowerment and Green Development, MESNAC Vice President Yang Huili demonstrated how artificial intelligence is deeply applied in rubber tyre making. She described an intelligent system that forms a continuous loop from sensing in real time and learning on its own to making smart decisions and carrying out closed loop actions. It applies industrial vision for accurate measurement with very few missed defects, uses MCC software to merge process data and correct within milliseconds and employs large models for maintenance that quickly locate faults with high precision to enable predictive repairs. Through both strategic leadership and hands on technical demonstration, MESNAC showed its dedication to advancing the industry under changing conditions.
