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.”

Continental has expanded its fifth-generation Conti Eco range for freight transport with the Conti Eco HT 5, a trailer tyre that joins the Conti Eco HS 5 steer and Conti Eco HD 5 drive products. The trio forms a coordinated package aimed at cutting operating costs, sustaining high mileage and lowering rolling resistance to support better fuel economy. Although trailer axles are not driven, their tyres still shape how efficiently a rig moves. By targeting that axle, Continental extends the Generation 5 advantages across the full vehicle combination for regional and long-haul duty. Less resistance at the trailer can translate into reduced fuel burn and, in turn, lower operational CO₂ output.

Because a trailer rolls on several tyres that never leave the road, those tyres directly affect stability, efficiency and day-to-day performance. In some configurations, they generate as much as half of a truck-trailer combination's total rolling resistance. Continental engineered the Conti Eco HT 5 to reconcile low rolling resistance with long tread life, encouraging uniform wear and dependable traction in a broad range of conditions. Optimised materials, a fresh sidewall design and advanced filler compounds underpin the tyre's fuel-saving characteristics.

Mileage and durability come from a new tread compound paired with a refined curing method, while a redesigned five-rib tread layout supports even wear, steady handling and consistent behaviour across shifting weather and road surfaces on both regional and long-distance routes. Tested against the Conti Hybrid HT3+, the Conti Eco HT 5 posted rolling resistance reductions of as much as 12 percent under specified conditions, offering fleets a path to lower fuel use, diminished CO₂ emissions and reduced tyre-related costs.

The Generation 5 Conti Eco portfolio sits within Continental's broader strategy of helping customers boost transport efficiency through technological innovation and tuned tyre performance. Uniting low rolling resistance, high mileage and long service life at every axle position, the range addresses industry pressures such as climbing fuel prices and stricter efficiency and emissions expectations. The Conti Eco HT 5 reaches the market in September 2026 in two sizes, 385/65 R 22.5 and 385/55 R 22.5.

Hinnerk Kaiser, responsible for the development of truck and bus tyres in the EMEA region at Continental, said, “Every tyre contributes to the efficiency and operating costs of a truck and trailer combination. While attention often focuses on the steer and drive axles, trailer tyres also play an important role in rolling resistance and fuel consumption. With the Conti Eco HT 5, we are extending the benefits of our fifth-generation Conti Eco portfolio to the trailer axle and helping fleets improve the efficiency of their transport operations. For the Conti Eco HT 5, our focus was on improving efficiency while maintaining durability. The combination of low rolling resistance, long service life and balanced wear characteristics can help fleets reduce tyre-related operating costs while maintaining reliable performance in demanding transport operations.”

Titan International, Inc. has reached a definitive agreement to divest its Italtractor ITM undercarriage business (ITM) to USCO S.p.A., marking a significant strategic shift for the global off-highway wheel, tyre and undercarriage manufacturer. The deal positions Titan to concentrate on its core operations while securing substantial cash value from the sale.

Under the agreement, Titan will receive an initial purchase price of USD 207 million, with the potential for an additional USD 6 million in earnout proceeds contingent on ITM meeting specified performance targets for 2026. Customary adjustments tied to ITM’s net asset and financial position at closing are expected to add approximately USD 23 million in cash value. Combined with USD 49 million in dividends from ITM – USD 38 million already received in recent years and USD 11 million anticipated before closing – Titan projects total cash value of up to approximately USD 285 million, inclusive of the earnout.

The transaction allows Titan to sharpen its focus on its global wheel and tire operations serving agricultural, construction and consumer markets. According to Chairman Maurice M Taylor, Jr, the potential sale of ITM was first discussed with the board over a decade ago when an offer below USD 100 million was presented. He credited President and CEO Paul Reitz and his team for their patience in completing a deal that he described as fair for Titan and beneficial for USCO, which gains a strong manufacturing business with a good brand and skilled workforce. Taylor also praised Cecilia La Manna for nearly 30 years of service and leadership, noting that USCO is acquiring a strong management team along with the business and plants.

Reitz characterised the transaction as an important step in Titan’s transformation, delivering strong value while providing ITM with an owner that understands the undercarriage sector. He said the deal enables Titan to direct people, capital and resources towards core wheel and tyre operations, pursue accretive growth opportunities and reduce debt. The move supports portfolio reshaping, accelerated strategic investments, transformative acquisitions and partnership, and long-term shareholder value.

As part of USCO, ITM will build on its position as a global provider of undercarriage components and complete solutions, with added focus and resources for long-term growth, customer service, product innovation and geographic expansion. ITM designs, manufactures and distributes undercarriage systems for construction, mining, forestry, road-building and agricultural applications through an international network and is a pioneer in undercarriage sensor technology, including its TRUST ITM monitoring solution.

Titan intends to use a portion of the proceeds to reduce existing debt and strengthen its balance sheet, with future capital deployment towards key growth investments, including accretive acquisitions and strategic partnerships. The transaction is expected to close in early January 2027, subject to customary closing conditions and required regulatory approvals, with both companies continuing ordinary operations until then. Gianni & Origoni and Poggi & Associati advised Titan and ITM on legal and tax matters, while USCO received assistance from Eidos Partners, Simmons+Simmons, BDO and KPMG.

NEXEN TIRE has unveiled the N’FERA Sport 2, an ultra-high-performance summer tyre succeeding the widely acclaimed N’FERA Sport. The original earned strong results in independent tests by leading DACH-region automotive publications, including ADAC and AUTO BILD, and secured multiple original equipment fitments. The new model adopts an updated tread pattern and revised construction to deliver sharper handling, shorter braking distances and dependable performance in both wet and dry conditions.

Structural rigidity has been raised by 15 percent over the predecessor, reducing tyre deformation and supporting stable behaviour during dynamic driving. NEXEN TIRE also incorporated Chamfer Technology, whose specially shaped block edges enlarge the contact area under braking and cornering. Meanwhile, the outer tread blocks are 5 percent wider, transferring vehicle power to the road more efficiently and improving cornering stability. A rim protector 7 percent wider than before adds protection against curb contact.

The tread design distributes pressure more evenly across the footprint, enlarging road contact and balancing handling, traction and braking while limiting heat buildup. Increased sidewall rigidity further cuts deformation and sharpens steering response, especially in high-speed corners. Collectively, these measures yield a 10 percent gain in cornering stiffness relative to the previous N’FERA Sport. Multi-width grooves and chamfered block edges widen the drainage area, helping evacuate water, lower aquaplaning risk and preserve wet-road grip.

Testing at Spain’s IDIADA Proving Ground demonstrated measurable gains over the outgoing tyre. NEXEN TIRE’s own results show an 11 percent shorter wet braking distance and a 2 percent shorter dry braking distance. Wet and dry handling improved by 7 percent, while cornering stiffness rose by 10 percent. The N’FERA Sport 2 is engineered to provide confident control across a broad range of road conditions.

Jeff Roh, Vice President of Europe Sales & Marketing, said, “Following the success of the N’FERA Sport, we expect the new N’FERA Sport 2 to deliver even stronger results. NEXEN TIRE has demonstrated proven quality and performance over the years, and with the improved capabilities of the new pattern, we aim to further enhance driving performance while helping drivers enjoy the thrill of driving with greater confidence and safety.”
