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 developed a new rear tyre solution for the fifth FIM Superbike World Championship round at the Czech Republic’s Most circuit. The track is known for unusually high mechanical strain on rubber, particularly at the rear axle. To address this, Pirelli created the F0468 medium compound rear specification. Its compound matches the D0922, a tyre used at Most in 2025 and at Phillip Island across the previous two seasons. However, the F0468 features an entirely new internal structure for better race-long consistency and improved stability.

This newcomer evolves the E0829 specification, which shared the same compound and appeared at Phillip Island earlier this year. Riders who dislike the F0468 can still choose the D0922 development rear tyre. That option has already proven itself at the unique Czech layout and at Phillip Island, another tyre‑killing circuit. For qualifying and the Superpole Race, Pirelli has designated the standard soft SC0 as the reference rear tyre.

Beyond the premier class, Supersport and SportBike World Championship competitors will also race at Most. Supersport riders receive the same front choices as Superbike: soft SC1 and medium SC2. At the rear, Supersport entries can pick the soft SC0 or the medium SC1. SportBike competitors have used that same medium SC1 on both axles all season.

The tyre lineup thus gives every category familiar options alongside the new F0468. By blending a proven compound with a revised structure, Pirelli targets greater performance consistency without forcing riders to abandon the trusted D0922. Most’s punishing layout will serve as the ultimate test for both solutions.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Over more than two decades as supplier to the Superbike World Championship, Pirelli has built an extremely solid and versatile tyre range. The SCX supersoft rear solution now represents an absolute benchmark for riders and is used in most races on the calendar, with the soft SC0 becoming a valid alternative on some occasions. There are, however, some circuits that are particularly demanding on tyres, such as Phillip Island and Most, which by virtue of their layout and intrinsic characteristics require more specific solutions and more durable compounds, typically medium options.

“In these cases, development work focuses on improving key parameters such as performance and consistency over race distance: objectives that guided the design of the new rear solution in F0468 specification. To complete the allocation, riders will in any case also have the well-proven D0922 option available, which has shown that it can effectively handle the particular stresses imposed by this circuit. It will be interesting to assess whether the new F0468 medium will be able to raise the performance level beyond that of the D0922 further still.”

Balkrishna Industries Ltd (BKT) has unveiled an ambitious expansion and investment roadmap aimed at more than doubling its revenue to around INR 230 billion by FY30, backed by a cumulative capital expenditure of INR 68 billion.

The company said the investment programme would strengthen its leadership in the off-highway tyre (OHT) segment, expand carbon black capacity and accelerate its entry into India’s on-highway tyre market. The strategy forms part of BKT’s long-term plan to achieve an estimated 8 percent global market share in the OHT segment by FY30.

BKT has already announced INR 13 billion of capex for OHT tyres in August 2024 and an additional INR 35 billion investment in May 2025 for on-highway tyres, rubber tracks, carbon black and power plant expansion. The board has further approved INR 20 billion in additional capex to support capacity expansion, infrastructure development, AI-enabled automation and sustainability initiatives.

As part of the OHT expansion strategy, BKT said ongoing debottlenecking and capacity enhancement initiatives would raise OHT tyre capacity to 425,000 metric tonnes per annum (MTPA). The company is also expanding its dedicated rubber tracks manufacturing facility while strengthening its mining tyre portfolio.

In the carbon black business, the company is scaling up production to improve raw material integration and energy efficiency. BKT said Phase 1 capacity has already been increased to 265,000 MTPA along with a 24 MW cogeneration power plant, taking total cogeneration capacity at Bhuj to 64 MW. Phase 2 expansion, which will raise carbon black capacity to 360,000 MTPA, is expected to become operational in Q1 FY27.

The company is simultaneously building its on-highway tyre business in India through a modular approach focused initially on premium passenger car radial tyres and commercial vehicle radial tyres. Commercial vehicle radial tyres were pilot launched in Q4 FY26, while passenger car radial tyres are scheduled for pilot launch in Q3 FY27.

For FY26, BKT reported standalone revenue of INR 106.56 billion, while net profit stood at INR 12.22 billion. OHT sales volumes rose 1 percent year-on-year to 317,356 MT.

The company said the expansion programme is expected to enhance profitability through stronger operational integration, scalable infrastructure and an expanded product portfolio, with blended EBITDA margins projected in the 23–25 per cent range after full commercialisation of the new capacities.
