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.”

Apollo Tyres Ltd has launched the Vredestein Perfect Tour+, a new urban bicycle tyre designed for reliability across diverse conditions. Engineered for daily commutes and longer tours, this tyre accommodates both traditional and electric bicycles, including higher-speed pedelec models, as confirmed by its full ECE R75 certification. This ensures its capability to handle increased loads and velocities while maintaining safety and comfort.

A key focus of the design is enhanced durability, achieved through a robust 5-mm puncture-protection layer. This reinforcement substantially diminishes the likelihood of flats from road hazards. For consistent performance in varied weather, the tyre utilises a specialised Optimum Silica Processing (OSP) compound. This technology provides secure grip on wet, slippery or snowy surfaces by improving the bond between silica and rubber, offering reliable traction even in colder temperatures.

Further contributing to its all-weather performance is a refined V-shaped tread pattern, which promotes stable roadholding without sacrificing efficiency. This design works to reduce rolling resistance, facilitating smoother and faster rides. The Vredestein Perfect Tour+ will be available from March in multiple sizes commonly used for touring and commuting, such as 50-559 and several 622 diameter options.

Nic Knippers, Divisional Head – Vredestein Two Wheel Tyres, Apollo Tyres Ltd, said, “The Perfect Tour+ continues our long tradition of developing touring products that combine safety, durability and reliable everyday performance. With its upgraded protection and advanced compound technology, it provides riders with even more worry-free kilometres of riding, whether they’re commuting or touring, and is fully able to harness the enhanced torque delivered by e-bikes and speed pedelecs.”

Hankook’s iON Race tyre played a defining role in the unpredictable third round of the ABB FIA Formula E World Championship in Miami. For this event, a new bespoke circuit configuration at the Miami International Autodrome presented fresh challenges with its temporary, non-uniform surface. These demands were intensified by a historic first: a wet-weather Miami E-Prix. As grip levels shifted dramatically from the initial safety car period onward, the tyre’s predictable warm-up behaviour and controlled thermal characteristics provided teams with a stable platform. This consistency was vital for managing the evolving conditions, allowing for strategic adaptation without sacrificing balance or race-long efficiency.

The race itself unfolded as a closely fought contest, ultimately won by Jaguar TCS Racing's Mitch Evans, who strengthened his championship position. Beyond supplying crucial performance on-track, Hankook engaged directly with the festival atmosphere of the Formula E weekend. The brand operated a dedicated Fan Village where attendees could explore the iON road tyre range and interact with displays highlighting Hankook’s philosophy and advancements in EV-specific tyre technology.

This Miami round, with its unique configuration and variable weather, served as a valuable proving ground. The insights gained from the iON Race tyre’s performance under such distinct pressures directly contribute to the ongoing development of Hankook’s broader electric vehicle tyre portfolio. With the Miami chapter complete, the championship's focus now shifts to the contrasting high-speed challenge of the Jeddah Corniche Circuit in Saudi Arabia.

Manfred Sandbichler, Senior Director, Hankook Motorsport, said, “Miami was a strong example of how important predictable tyre behaviour is on a newly introduced Formula E layout at an iconic venue. As grip levels evolved throughout the weekend, the iON Race delivered the stability and consistency required to support competitive racing under changing conditions.”

King Willem-Alexander inaugurated what Circtec calls Europe’s largest and most advanced chemical recycling facility for end-of-life tyres, marking the start of operations at the company’s Delfzijl plant in the Netherlands’ northern chemical cluster.

The facility, whose investment was announced in May 2024, has completed construction and commissioning of its first phase and is now processing 50,000 tonnes of waste tyres a year. During the ceremony, the King symbolically began operations by feeding tyre material into Circtec’s proprietary CIFR pyrolysis reactor. The event was attended by the Netherlands’ Deputy Prime Minister and Minister of Climate and Green Growth, along with the British Ambassador to the Netherlands.

Circtec’s technology converts discarded tyres into a slate of products including a marine fuel marketed as HUPA, circular naphtha for use in plastics and chemicals and recovered carbon black for reuse in tyres, rubber and plastics. The plant can also supply tyre pyrolysis oil to petrochemical and refining customers as a lower-carbon feedstock.

The Delfzijl project follows more than 15 years of technology and product development by the company. At current capacity, the plant is expected to process roughly 6 percent of Europe’s annual waste tyre stream. More than half of Europe’s end-of-life tyres are still burned in cement kilns or exported to Asia for disposal, according to Circtec.

An ISO-standard life cycle assessment commissioned by the company indicates the plant could cut greenhouse gas emissions equivalent to about 3 percent of the Dutch chemical industry’s national emissions once the site reaches full scale.

Circtec plans to begin construction of a second phase later this year, expanding capacity in modules to a total of 200,000 tonnes of tyres a year.

The company has secured long-term offtake agreements for its entire output. Birla Carbon will take the recovered carbon black for its Continua de-carbonisation product line, while British Petroleum has contracted volumes of the marine fuel, circular naphtha and tyre pyrolysis oil.

The project is backed by Novo Holdings and A.P. Moller Holding, which closed a Euro 150 million funding round for Circtec in 2024. The company is planning additional plants globally, both as owner-operator projects and through joint-venture licensing.

During the visit, the King toured the facility and met employees as well as representatives from British Petroleum, Birla Carbon and Dutch tyre recycling body RecyBEM. Discussions also involved local and regional authorities on the plant’s economic and environmental role in the Groningen region.

Commenting on the occassion, Circtec Chief Executive Officer Allen Timpany said, “Circtec now moves forward to operate the first phase of this plant and to expand it to its full designed and permitted size. Let us work together to scale this success further. So that this plant may inspire others, here in the Netherlands and far beyond, to rethink waste, reimagine value, and to keep moving forward, tenaciously, innovatively, and with strategic vision toward a sustainable and resilient industrial future”.

Speaking during the inaugural ceremony, Netherlands Deputy Minister and Minister of Climate and Green Growth Sophie Hermans said, "What we see here at Circtec is Green Growth at its best. Every year, 180,000 tonnes of used car tyres will be given a second life as a high-quality raw material. That is circular economy on an industrial scale. This factory shows that we can and want to become more sustainable in the Netherlands and dare to build new, future-proof industry. Good for our climate, good for our economy and good for the earning capacity of the Netherlands."
