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.”

Bridgestone Corporation has announced a significant advancement in environmental research with the development of an industry-first vehicle collection method for tyre and road wear particles (TRWP) specifically from truck and bus tyres. This innovation is designed to enhance scientific understanding of how such particles may interact with the environment. Tyre and road wear particles are generated through the friction between a tyre’s tread and the road surface – a process essential for vehicle safety and comfort – and consist of a combination of worn tyre material and fragments of road pavement. The newly developed collection method for trucks and buses was also showcased at the Tire Technology Expo 2026, held from 3 to 5 March in Hannover, Germany.

The company had previously introduced a collection method for passenger car tyres in 2025 and has since been working to improve its efficiency. Applying insights gained from that earlier development, particularly regarding how particles are generated and dispersed, Bridgestone created a proprietary system tailored to the larger scale of truck and bus tyres. To ensure the accuracy of the collected samples, the company used a dedicated proving ground designed to replicate real-world driving conditions. Before each test, the track was meticulously cleaned to prevent contamination from pre-existing debris.

For the collection process, Bridgestone engineered suction devices and intake mechanisms compatible with larger tyres. A sturdy aluminium frame was used to construct the tyre cover, ensuring durability against strong winds during operation. Following controlled driving sessions, particles that remained both on the track surface and inside the tyre cover were gathered for analysis.

This effort is part of a broader commitment to investigate the physical and chemical characteristics of tyre wear particles and their potential environmental effects. Bridgestone participates in the Tire Industry Project (TIP) facilitated by the World Business Council for Sustainable Development and collaborates with external research organisations and corporate partners. With the ability to collect samples from both passenger vehicles and heavy-duty trucks and buses, the company aims to accelerate research, share findings widely and support efforts to reduce particle generation.

Alongside this research, Bridgestone is advancing several complementary initiatives. These include developing longer-lasting tyres with improved wear resistance, offering solutions that help customers lower total operating costs and working to minimise environmental impact throughout the product lifecycle.

Vittoria has unveiled the next generation of its Air-Liner Light Road, an ultralight tubeless insert refined to satisfy the rigorous demands of contemporary road cycling. Building upon its predecessor, this iteration features a completely overhauled material composition and a novel manufacturing technique that elevates performance, simplifies setup and enhances dependability, all while maintaining its featherlight profile.

Engineered with input from WorldTour professionals, the Air-Liner Light Road delivers puncture support, steadfast bead security and consistent rim defence without diminishing ride quality. The pivotal advancement lies in the transition to an extrusion process. This shift produces a structure with more uniform closed cells and a smoother exterior.

The new material significantly minimises sealant absorption, permitting the use of up to 10 percent less sealant. For optimal protection, it is advised to add 10 ml more than a standard tubeless setup. In the event of a flat, the enhanced run-flat capability delivers a ride comparable to approximately 14.5 psi, allowing a rider to continue for up to 50 kilometres.

Installation is more effortless, as reduced internal friction helps the insert settle perfectly. It also diminishes the likelihood of tyre burping by 28 percent at lower pressures compared to setups without an insert. Remarkably, these enhancements are achieved without any weight penalty, with each unit ranging from 30 to 40 grammes.

Functioning as a dynamic component, the insert expands upon air loss to facilitate run-flat mode. Beyond emergency support, it empowers riders to safely utilise lower pressures for heightened grip and comfort, effectively absorbing shocks from rough pavement.

Having been tested by Vittoria's professional teams, the Air-Liner Light Road is already a staple for many riders. To ensure a perfect match, Vittoria has printed tyre width compatibility directly on the insert. This new model completes the Air-Liner range, providing a dedicated solution for every discipline. With cyclists prioritising precise pressures for optimal performance, this insert answers the call for greater safety and reliability, extending benefits beyond the competitive peloton. Each insert comes supplied with a Vittoria Multiway Tubeless valve.

Stijn Vriends, Chairman & CEO, Vittoria, said, “At Vittoria, our objective is to elevate every cyclist’s ride. With our new generation of Air-Liner for road, we complete our vision of total tyre system performance across every terrain. From the WorldTour to everyday riders, from smooth asphalt to rough gravel sections, we give cyclists the confidence to ride faster, further and with complete peace of mind – because performance should never stop when the road gets tough!”

Andreas Klier, Technical Operations and Commercial Manager, EF Education-EasyPost, said, “The new Air-Liner Light Road is a real gamechanger. In races like the Northern Classics, it gives us greater control and confidence on rough roads and pavé, letting us ride at lower pressures without compromising performance or safety.”
