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 Tyre Recovery Association (TRA) has warned that UK’s circular economy goal will remain out of reach if waste tyre processing continues to move abroad. Environment Agency data shows enhanced verification measures introduced last October have a compliance rate below two percent, a figure the TRA described as deeply concerning. Without a fundamental shift in policy and enforcement, a closed-loop system cannot be realised.

Exporters are systematically ignoring the new rules. Of 4,189 waste tyre shipments since 1 October 2025, only 54 post-shipment forms were completed correctly, a compliance rate of just 1.3 percent. The vast majority of UK’s annual 300,000 tonnes of tyre exports end up at illegal batch pyrolysis plants in India. The TRA called this both an environmental failure and an economic loss, as the UK ships abroad the very feedstock needed to power its own circular economy.

While the UK treats waste tyres as a disposal problem, the domestic sector holds 150,000 tonnes of licensed but idle processing capacity. The TRA argued that with enforceable regulation and proper oversight, the industry could expand significantly, creating skilled jobs and generating high-value secondary materials at home instead of losing them overseas.

Shredding tyres reduces environmentally harmful disposal and unlocks new value streams. Shredded tyres are strategic feedstock for sustainable aviation fuel, advanced continuous pyrolysis, recovered carbon black for new tyre manufacturing and rubberised asphalt for long-life roads. The TRA urged immediate regulatory action to stop uncontrolled exports and activate dormant domestic processing capacity without further delay.

Peter Taylor OBE, Secretary General, Tyre Recovery Association, said, “The Environment Agency’s transparency is very welcome, but the figures are an indictment of those tyre export brokers who continue to operate without conscience. To see a compliance rate of just 1.3 percent is ultimately depressing, these measures are a long way off having any meaningful impact.

“New measures need to be introduced so that EA can fulfil their statutory duty; until then, the export chain simply continues to abuse their goodwill. We must face the hard reality. Shred is the only immediate route to a circular economy and sustainable future for British operators. Unless we mandate that tyres must be mechanically processed into shred before they leave our shores, we will continue to fuel pollution abroad while our domestic recycling assets wither.

“Our neighbours and competitors are realising the opportunity from secondary materials. We continue to export the UK’s future in the back of shipping containers, while the rest of the world builds a circular economy. If the UK does not move to a shred-only mandate, we will be left behind.”

Pirelli has claimed the top position in a recent ranking of the world’s fastest road-legal track tyres, according to the Tyre Reviews platform. The comparison, which evaluated four products available in Europe and North America, crowned the P Zero Trofeo RS as the pinnacle of Pirelli’s road range. The tyre integrates technological solutions derived from the Italian company’s 120 years of motorsport experience at the highest levels.

During dry handling tests, the P Zero Trofeo RS set the fastest lap time and was described as clearly superior. Tester Jonathan Benson noted he had to recalibrate his braking points twice due to unexpectedly high grip levels. The tyre enabled quick and precise turn-in, earlier throttle application and immediate traction on corner exits, with the front axle delivering strong grip and confidence. It also ranked first in dry braking with the shortest stopping distance.

Consistency of performance under demanding conditions was another standout feature, confirming the product’s ability to maintain high performance over time. These results were reinforced by a separate test from Auto Bild Sportscars, which compared five road-legal semi-slick tyres. There, the P Zero Trofeo RS also secured first place with an ‘Exemplary’ rating thanks to best-in-class dry performance and long-distance consistency.

Designed for track use yet approved for road driving, the P Zero Trofeo RS was originally developed for original equipment and is now available on the replacement market. It brings Pirelli’s expertise from bespoke fitments for high-performance prestige and premium models to all customers. While conceived to maximise vehicle performance on the track, Pirelli engineers have also ensured a high level of safety on wet surfaces.

Goodyear Racing Eagle tyres emerged as the central strategic battleground in the LMGT3 class during the FIA World Endurance Championship’s season-opening 6 Hours of Imola. The Italian circuit’s notably smooth asphalt led to unexpectedly low tyre degradation across the six-hour race, which allowed teams to experiment with varied tactical plans rather than following a single, predictable approach. Under this season’s increased tyre allocation rules, teams enjoyed greater flexibility, although not every squad chose to use its full supply.

The performance and consistency of the Goodyear Racing Eagle Medium compound proved decisive, with most teams minimising pit lane time by double- or triple-stinting their tyres. However, a minority of competitors opted for a contrasting strategy, fitting fresher Goodyear Racing Eagle tyres more frequently. Crucially, the durability of the Medium compound ensured that both approaches remained competitive, resulting in a wide array of live strategies unfolding simultaneously across the LMGT3 field.

The FIA World Endurance Championship resumes with the TotalEnergies 6 Hours of Spa-Francorchamps from 7 to 9 May 2026. Over the same weekend, Goodyear Racing Eagle tyres have also been in action at Kansas Speedway in the NASCAR Cup Series and NASCAR O’Reilly Auto Parts Series, as well as at Donington Park for the British Touring Car Championship season opener.

Stephen Bickley, Goodyear Endurance Programme Manager, said, “In the first half of the race, we saw several teams double stinting the unloaded left-hand side, but changing their right-hand side tyres at every stop. But as the race progressed, some teams began to double-stint both sides. This meant that teams that had only changed the right-hand side at the previous stop were onto their third stint with the left-hand tyres. Across the field, we saw some teams stop as little as five times during the race, and some as many as eight, emphasising the range of different strategies teams employed.”
