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.”

Nexen Tire reported record first-quarter revenue and higher profitability, supported by stronger sales in Europe and North America and a shift towards higher-value products.

The company said revenue rose to KRW 838.3 billion in the three months to March, while operating profit reached KRW 54.2 billion. The increase came despite a “hostile business environment” marked by slowing global demand and geopolitical risks.

Sales were driven by solid performance in key markets, notably Europe and North America. A recent plant expansion in Europe improved production stability, enabling higher volumes from existing customers and new client wins.

Original equipment (OE) sales remained stable, supported by a diversified product portfolio, even as global automotive demand weakened.

Profitability improved on the back of a more favourable product mix and cost controls. The share of high-value products — including premium OE tyres and those for sport utility vehicles and electric vehicles — continued to rise. High-inch tyres, defined as 18 inches and above, accounted for 40 percent of total sales.

The company also said efforts to offset higher raw material and ocean freight costs contributed to margin gains.

Alongside its results, Nexen outlined measures to strengthen its global position, including expanding region-specific product offerings. In South Korea, it launched the high-performance N’FERA Sport and the all-weather N’BLUE 4SEASON 2, following earlier introductions in Europe and the US.

In Latin America and the Asia-Pacific region, Nexen introduced the N’BLUE S summer tyre and pursued partnerships with local distributors to bolster retail competitiveness.

With external uncertainties expected to persist into the second quarter, the company said it would accelerate diversification of its global sales structure while maintaining growth in strategic markets such as Australia and Japan.

Nexen also plans to expand regional distribution centres and advance its AI-based virtual development process using a high dynamic driving simulator introduced last year.

A Nexen Tire official said: “We achieved solid results despite the uncertain business environment. We will continue to respond proactively to market changes while strengthening product competitiveness and operational efficiency to sustain quality growth.”

Goodyear has reinforced its position as an all‑season tyre pioneer on the eve of the 50th anniversary of the world’s first all‑season tyre. The company introduced the Vector All Season 4, an engineering milestone shaped by decades of expertise and an award‑winning portfolio. With a new high‑contrast sidewall design and rim diameter coverage now reaching 23 inches, the tyre unlocks premium year‑round capability for vehicle segments that previously lacked any all‑season solution.

The Vector All Season 4 delivers optimised performance on dry roads, in rain and on light snow, carrying the European Three‑Peak Mountain Snowflake certification. Developed with Goodyear’s latest technologies and dedicated materials, the tyre balances capabilities without compromising any single performance area, allowing it to adapt to changing temperatures, road conditions and driving styles.

Independent testing by TÜV SÜD, commissioned by Goodyear, confirmed the tyre as a well‑rounded product with consistently strong performance across all evaluated criteria, while AutoBild awarded it an ‘Exemplary’ rating. The tyre’s WeatherReady Technology, combining Dry Contact Plus, a 3D Blade Sipe System and a new compound formula, supports confident grip, effortless dry and wet control, improved tread wear and reduced rolling resistance – making it well suited for electric vehicles.

Designed for today’s heavier, more powerful and increasingly electrified vehicles, the Vector All Season 4 responds to evolving market demands with broader fitment. By 2026, the lineup will include 96 SKUs across 16‑ to 23‑inch rim diameters, with 66 percent of the range in 19 inches and above. For the first time, models such as the Range Rover, Range Rover Sport, Porsche Panamera and Macan, as well as the Audi A6 e‑tron, Q7 and SQ7, can combine confident all‑season performance with year‑round convenience. Fitments of 19 inches and above feature an exclusive laser‑engraved sidewall.

Ben Glesener, Senior Technology Director Product Development Consumer EMEA, said, “Goodyear has played a defining role in shaping the all-season category since its very beginnings, starting with the launch of Goodyear Tiempo in 1977 – the world’s first all-season tyre. As we approach the 50-year anniversary of that milestone next year, Vector All Season 4 represents the next step in how we continue to redefine the all-season category. By raising all‑season performance and expanding the range to meet the demands of today’s premium and electric vehicles, we are making it easier than ever for more drivers to rely on a single tyre solution throughout the year.

Bridgestone is broadening its premium agricultural tyre portfolio for next-generation high-horsepower tractors. The company has added six extra-large sizes to its VT-TRACTOR range, covering 38-to-46-inch rims. These XXL tyres deliver superior traction, extended wear life and enhanced durability. An optimised rolling circumference ensures ideal lead percentage between front and rear tyre combinations, which is critical for maintaining proper driveline synchronisation and preventing mechanical stress under heavy field loads.

Advanced design features enable these performance gains. Developed using virtual three-dimensional simulation and robust Bridgestone design criteria, the tyres incorporate deeper and wider tread profiles that balance traction with even wear distribution. A patented involute lug design provides up to 12 percent more lug volume than competitors, maximising grip while minimising energy loss. This design maintains consistent performance over extended working seasons, reducing the need for premature replacements and lowering operating costs for farmers.

Durability comes from Bridgestone’s unique S-LINE bead profile, offering greater flexibility at lower pressures to reduce soil compaction and prevent rim slip. The high durability casing ensures even pressure distribution across the soil footprint, preventing both circumferential and shoulder cracks while improving tyre longevity. The tyres are fully compatible with Central Tyre Inflation Systems, allowing operators to adjust pressure on the move for different applications. Additional benefits include improved fuel efficiency and stable steering precision even under challenging field conditions.

Production takes place at Bridgestone’s Puente San Miguel plant in Spain, following significant upgrades to manufacturing capabilities including advanced production technology and specialised equipment for large-diameter tyres. These investments enable expansion into the 44- and 46-inch segment. The new XXL sizes will launch progressively from April 2026, expanding compatibility with a wider range of modern high-horsepower agricultural machinery across global markets.

Andrea Marconcini, Director Agriculture at Bridgestone EMEA, said, “Today, farmers operate larger, more powerful tractors and need tyres that can keep up – doing more and going further in demanding conditions. Our updated VT-TRACTOR range is engineered to enable faster, more efficient work in the field, together with a longer service life that reduces long-term costs.”
