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.”

Pirelli has confirmed the tyre compound options for the Miami Grand Prix, with teams receiving the three softest mixtures: C3, C4 and C5. The first United States race of the Formula 1 season takes place next weekend in Florida following a lengthy break caused by the cancellation of the Bahrain and Saudi Arabian Grands Prix. The championship resumes on a street circuit built around the Hard Rock Stadium, featuring a 5.412-kilometre layout over 57 laps.

The Miami International Autodrome presents 19 corners and three long straights on asphalt resurfaced in 2023. The track surface has low roughness and gains grip as the weekend progresses. A notable characteristic observed last year was the circuit’s ability to dry very quickly, demonstrated during the Sprint when drivers switched from intermediates to slicks despite heavy rain before the start.

Fewer uncertainties are expected in race strategy due to historically limited tyre degradation in Miami, allowing drivers to extend stints and complete the Grand Prix with only a single pit stop. Neutralisations remain a factor on Sunday, as precision is crucial on any street circuit. Last year’s victory by Oscar Piastri followed a straightforward approach, with drivers splitting between Medium and Hard compounds before a mid-distance pit window.

Of the four editions held around the Dolphins’ stadium, half have been won by Max Verstappen, while McLaren drivers have shared the last two victories. Lando Norris won in 2024 followed by Piastri in 2025, though neither McLaren driver has ever secured pole position at this event. Verstappen has two poles, with the others taken by Charles Leclerc and Sergio Perez.

The entire Miami weekend operates under the Pirelli banner, as all support categories are supplied by the Italian company. The second round of Formula 2 has been relocated to Florida, joined by the McLaren Trophy North America and the Porsche Carrera Cup North America. The latter series now receives Pirelli’s P Zero DHG compound introduced last season.

The Miami podium cap, designed by Denis Dekovic for Pirelli Design, draws inspiration from a sea predator with grey shades resembling shark skin. The animal is also referenced by visor stickers depicting jaws or body. The special edition cap is already available for purchase online.

The Automotive Tyre Manufacturers’ Association (ATMA) has called on the Government of India to introduce customs duty relief on critical raw materials due to supply chain instability from the West Asia crisis. ATMA acknowledged the government’s temporary duty exemption on synthetic rubber and certain resins until June 2026 as a constructive step.

Despite this, ATMA noted that inputs like tyre cord fabric, bead wire, steel cord, carbon black, processing oils and petrochemical chemicals still attract high import duties during price volatility and supply constraints. Crude-linked inputs account for up to 70 percent of raw material costs, with volatile crude prices and stressed shipping routes raising costs, delaying shipments and increasing freight and insurance premiums.

ATMA also highlighted bead wire shortages caused by domestic industrial gas and LPG issues, requesting a temporary waiver from Quality Control Order requirements for imports. The association sought sulphur supplies for tyre manufacturers and urged refineries to sustain process oils while shifting towards high-value materials like Neodymium Polybutadiene Rubber.

ATMA warned that raw material disruptions could affect farm and logistics tyre supplies. The association reaffirmed support for Make in India and self-reliance, stressing continued government-industry dialogue to protect original equipment manufacturers, transporters, farmers and consumers.

Arun Mammen, Chairman, ATMA, said, "We appreciate the Government’s timely support. However, given continued global uncertainties, extending duty relief to other critical raw materials is essential to maintain production stability and cost competitiveness."
