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.”

Michelin unveiled the MICHELIN X Multi T2 at IAA Transportation 2026 in Hannover, presenting the trailer tyre in the widely used UK and Ireland size of 385/65 R22.5. Designed for regional and mixed transport operations, the tyre is engineered to manage heavy loads, resist lateral forces during manoeuvring and remain dependable across fluctuating operating conditions.

Compared with its predecessor, the X Multi T2 delivers as much as 15 percent greater mileage and up to 6 percent reduced rolling resistance. Its development centres on carcass stability and robustness, making it suited to demanding trailer duties spanning general cargo, containers, refrigerated goods, tankers and bulk haulage, along with car, specialised and heavy-haul transport. Such operations frequently involve peak loads, tight manoeuvring and inconsistent road surfaces, all of which affect tyre life, so a durable carcass and damage-resistant tread directly support cost-effectiveness.

Four principal innovations underpin the tyre. REGENION technology continuously forms new grooves as the tread wears, preserving grip and mobility throughout service life. The CARBION compound enhances mileage, rolling resistance and wear resistance. Within the structure, OPTICOIL is a weight-saving bead architecture, while DURACOIL strengthens the tyre-to-rim bond for greater stability. Michelin also employs POWERCOIL, a newer generation of lighter, longer-lasting steel cables.

As a multi-life product, the X Multi T2 can be regrooved and retreaded for notable total cost of ownership (TCO) savings. Regrooving takes place once tread depth reaches 3–4 mm, extending casing life in its most fuel-efficient state. Worn regrooved tyres can then be retreaded as Michelin Remix tyres at the company's Stoke factory, a process adding roughly 20 kg of raw materials versus about 70 kg for a new tyre. Retreads follow the local-to-local principle, being used exclusively within UK and Ireland, supporting skilled domestic jobs and avoiding export-related environmental impact. The tyre carries rolling resistance class B, wet grip class C and external noise class A under EU labelling, plus 3PMSF and M+S winter markings.

Andrew French, B2B Sales Director, Michelin UK & Ireland, said, “Alongside durability and versatility, Michelin recognises the growing pressure hauliers face to reduce rolling resistance, as trailers form an integral part of the total cost of ownership (TCO) equation. This is something our latest generation trailer tyre can help operators to achieve.”

Goodyear Chile has reinforced its dedication to sustainability and the circular economy through programmes that encourage responsible handling of end-of-life tyres while supporting environmental protection across the country.

Beyond producing and selling tyres, the company ensures its discarded products are managed in an environmentally sound manner. These tyres are collected and treated at authorised recycling plants, where mechanical processes convert them into reusable materials suitable for new products and applications, in line with Chilean regulations for out-of-use tyres and the firm’s sustainability goals.

Goodyear Chile also continues working to meet requirements under Chile’s Extended Producer Responsibility Law. It currently uses two management mechanisms tied to regulatory categories. For Category A, covering tyres with rims under 57 inches except those measuring 45, 49 and 51 inches, the company participates in NEUVOL, a collective nonprofit system focused on collecting and recovering end-of-life tyres. Together with NEUVOL, Goodyear Chile sends these tyres to Polambiente, a Santiago-based recycler specialising in mechanical recycling that turns them into raw materials and products for new uses.

For Category B, which includes tyres with rims of 45, 49 and 51 inches and wheels 57 inches or larger, Goodyear Chile has operated under a management plan approved by the Ministry of the Environment since 2022, becoming the first Category B tyre company to secure such authorisation in Chile. It has consistently met annual collection and recovery targets for 2023, 2024 and 2025. These tyres go to Rembre Tires in northern Chile, where granulation recovers 100 percent of the tyre, separating rubber and steel for various applications.

Goodyear Chile’s responsible tyre management predates the REP Law targets and reflects its broader effort to cut environmental and social impacts. For over 10 years, it has advanced recycling initiatives and maintained a zero-waste-to-landfill policy while continuing research into more sustainable materials, including alternative raw materials, to help Chile reduce waste and build a more sustainable future.

Hankook Tire, the exclusive tyre supplier for the FIA World Rally Championship, wrapped up its support for the 12th round of the season. The WRC Rally Chile Biobío concluded on 13 September near Concepción, Chile, with Hankook’s off-road Dynapro R213 tyres proving central to the event.

The rally featured 16 special stages covering 311.18 competitive kilometres. Competitors tackled forest roads and rugged, unpaved mountain terrain around Concepción and the Biobío region, beside Chile’s Pacific coast. The route blended fast corners with compacted gravel made of volcanic ash particles and small stones, severely testing both drivers and tyres. Repeated runs over rough ground magnified the difficulty.

Hankook’s Dynapro R213 was available in Hard and Soft compounds, letting teams strategically select tyres for surface and weather conditions. The tyre offered flexibility on steep slopes and across varied ground, from soft earth to thick gravel. Oliver Solberg of Toyota GAZOO Racing claimed his second win of the season, following his Rallye Monte-Carlo triumph. The result also earned Toyota the 2026 Constructors’ Championship, its sixth straight since 2021 and tenth overall.

The 2026 WRC season now moves to the 13th round, WRC Rally Italia Sardegna, scheduled for 1–4 October near Alghero, Sardinia. That event combines demanding coastal and interior mountain roads, with tight corners and blind crests that restrict forward visibility, placing high demands on tyre traction and durability.

Bridgestone has unveiled the V-Steel Highway Service 3 (VHS3), a new high-speed radial tyre engineered for mobile all-terrain cranes. As a global leader in premium tyres and sustainable mobility solutions, the company designed the product to enhance vehicle and fleet performance. The VHS3 delivers improved wear life while helping reduce downtime and maintenance costs, enabling operators to perform confidently in demanding environments.

Compared with its predecessor, the VHS2, the new tyre offers up to 12 percent longer wear life. Bridgestone achieved this through an advanced rubber compound technology and an optimised contact area that minimises irregular wear. A new tread design featuring wide grooves and extended lug blocks further combines longer wear life with improved grip and stability on highways and off-road terrain.

The VHS3 is also 24 kg lighter than the VHS2, assisting fleets in reducing fuel consumption and operational costs while maintaining durability and improving load capacity. This results from a lighter casing design with a lighter belt construction. Bridgestone's new crane tyre will be available from September 2026 in size 445/95R25 178F.

Bas Rijpma, Fleet Manager, Sarens Netherlands, said, "In our business, reliability, uptime and efficiency are critical. Bridgestone has been a trusted partner to Sarens for more than a decade. As the next generation crane tyre, the VHS3 is already delivering very promising results. We have observed no irregular wear, the robustness we require for demanding heavy transport operations and favourable fuel efficiency potential thanks to its lighter weight. Combined with the TPMS solution, which gives us real-time insight into tyre pressure and temperature, the VHS3 helps us optimise tyre performance and minimise downtime. Together with low noise levels, it gives us confidence that Bridgestone VHS3 is setting a new standard for crane tyre performance."
