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.”

Hankook Tire has secured the title sponsorship of Rally US, Round 11 of the 2027 FIA World Rally Championship, the company announced during a signing ceremony at the 2026 SEMA Show in Las Vegas on 3 November. Representatives from Hankook, the WRC Promoter and the Rally US Organizing Committee attended the event.

The agreement grants Hankook naming rights to the rally, which will be staged as Hankook Rally US under the company’s unified global brand. It represents Hankook’s first title sponsorship of a WRC round.

Hankook Rally US will mark the WRC’s return to the United States after 39 years, since the Olympus Rally in Washington State in 1988. Set for 25–29 August 2027, the event will run on gravel stages across Tennessee and Kentucky, with Knoxville serving as rally headquarters and a ceremonial start in Nashville, which also hosts Hankook’s US headquarters.

Through the sponsorship, Hankook seeks to boost brand awareness in North America, especially in the US, one of the world’s largest automotive markets. The company plans to use exposure across rally stages, the WRC Arena, fan zones and podium backdrops to engage local motorsport fans and strengthen ties with customers and partners. Hankook has supplied tyres exclusively to all WRC classes since the 2025 season and supports more than 70 motorsport competitions worldwide, feeding event data into high-performance tyre research and development.

Rob Williams, Senior Vice President of Hankook Tire North America Headquarters, said, “The WRC’s historic return to the US marks a milestone for Hankook as our first title sponsorship of a WRC round. This partnership will showcase our tyre technology, elevate our premium brand presence and strengthen ties with customers and partners across North America.”

Matt Crews, President and CEO, Rally US, said, “We’re proud to represent America’s return to the World Rally Championship, and especially proud to do it alongside Hankook. Tennessee is my home state, and Hankook is a leader in our automotive industry, with its US headquarters in Nashville and its plant in Clarksville. Hankook Rally US gives them a great platform to showcase their brand to fans here at home and to the WRC’s audience around the world.”

Senator Bill Hagerty said, “Hankook has been a great employer and partner for the Tennessee economy since they decided to move operations to our state more than a decade ago. Seeing them serve as title partner for the FIA World Rally Championship’s return to America, right here in Tennessee, will put our state in front of a global audience, and I couldn’t be more pleased of how far that relationship has come.”

Firestone, a Bridgestone Americas subsidiary, has introduced the Firestone Pathway AS, an all-season touring tyre built for everyday drivers. It comes in 73 sizes, giving it the widest vehicle coverage of any Firestone tyre, and pairs dependable performance and long tread life with value, all backed by a 65,000-mile limited mileage warranty.

Development was shaped heavily by consumer feedback, which pushed improvements in wet traction, tread life and ride comfort over the predecessor. The original plan called for 48 sizes, but 25 more were added mid-development to broaden market reach, helping Firestone cover nearly 77 percent of registered vehicles.

A tread compound engineered for longevity, additional sipes and an optimised see-through void promote even wear and sustained traction. Deep interlocking 3D sipes deliver grip from light snow to dry and wet pavement. Internal testing recorded wet braking gains of 18 percent against the Uniroyal Laredo HT, 11.7 percent against the Firestone All Season and 7.4 percent against the Toyo Extensa AS2, along with shorter dry braking than six leading rivals. Low rolling resistance also supports fuel efficiency in combustion-engine vehicles.

Nationwide availability is underway, with fitments covering popular models such as the Toyota Camry, Toyota RAV4, Subaru Outback, Jeep Grand Cherokee and Chevrolet Equinox.

Leslie Sawyer, Senior Product Design Engineer, Bridgestone Americas, said, "Most drivers want a tyre they can depend on. The Firestone Pathway AS is designed to deliver reliable performance and long-lasting value, giving drivers the confidence they need in everyday driving situations."

Scandinavian Enviro Systems AB (publ) has entered into a conditional service agreement with an international operator that provides transport services to the energy sector. The agreement follows a letter of intent signed by the two parties on 17 March 2026 and marks a further step towards establishing a tyre pyrolysis plant in North America. Using Enviro’s technology, the facility is intended to recycle up to 50,000 tonnes of end-of-life tyres annually.

Under the terms of the agreement, Enviro will produce the technical documentation needed for the plant’s permit applications and prepare an initial design for the entire facility. For these services, the company will receive a fixed fee of USD 2,000,000, corresponding to approximately SEK 19.5 million. The fee is divided between USD 500,000 for permit application work and USD 1,500,000 for plant design, with USD 450,000 payable once the customer decides to proceed and the remainder paid in instalments as various parts of the services are delivered. Additional work and technical support beyond the fixed-fee scope will be invoiced on an ongoing basis.

The start of Enviro’s work depends on the customer making a final decision to proceed with the project. That decision, in turn, requires the customer to have secured a site for the plant and to have entered into binding agreements with buyers of the plant’s two main products, oil and carbon black, covering at least 75 percent of expected production for each product. Should the customer neither decide to proceed by 31 December 2027 nor elect to continue, the agreement will terminate.

The assignment covers two principal deliverables: technical documentation required for environmental, planning and fire safety permit applications and an initial design of the whole plant, including drawings, equipment lists, calculations and technical specifications. The design will serve as the basis for more detailed engineering work before an investment decision. Enviro will also provide technical support during the permit application process for 12 months after delivering the permit documentation. The agreement does not grant any right to use Enviro’s technology to construct or operate the plant, which would require a separate licence agreement.

According to the timetable, the assignment is expected to be completed about seven months after the customer’s decision to proceed, with permit application documentation ready after roughly five months. The customer may terminate the assignment with 30 days’ notice, in which case Enviro is entitled to compensation for work performed and costs already incurred. Enviro remains entitled to compensation regardless of whether permits are granted or the plant is ultimately built. The agreement is described as an important step in Enviro’s strategy to establish technology-based plants internationally, with the design potentially forming the technical basis for a future licence agreement.

Fredrik Aaben, CEO, Enviro, said, “This is an important step towards establishing Enviro’s technology in North America. Together with the Customer, we are now moving from a letter of intent to a binding conditional agreement, and we look forward to designing the plant as soon as the project is ready to proceed.”

Dunlop Motorcycle Europe has extended its partnership with the Federazione Motociclistica Italiana (FMI), confirming it will remain title sponsor and exclusive tire supplier to the Campionato Italiano Velocità (CIV). The renewal, announced on Thursday 5 November at EICMA in Milan, follows three years in the role at one of Europe’s most competitive motorcycle racing championships. The new agreement covers another four seasons beginning in 2027.

Riders across the Superbike, Supersport, Sportbike, Moto3 and Moto4 classes will continue to use Dunlop tyres and receive backing from the company’s trackside support engineers. The announcement comes weeks after Dunlop was confirmed to continue supporting the FIM Endurance World Championship, and this sustained involvement in highly competitive series underlines Goodyear’s long-term investment in European motorcycle racing through its Dunlop Motorcycle Europe business.

CIV remains central to Dunlop’s development of racing and track day tire specifications and technologies that inform the next generation of road tyres. In 2027, the company will introduce the KR111 front tyre, successor to the KR109, following validation in real-world CIV conditions; a version raced by Supersport teams this year carried the development name G2_01 VAL4.

The KR111 has a different profile and construction and will be available to racers and track day riders at all levels, while Supersport teams will also run a new development KR108 rear tyre next year. The 2027 season opens on 24–25 April at Misano before visiting Mugello, Cremona, Imola and Vallelunga, with a July return to Misano for the CIV Racing Night.

Roberto Finetti, Marketing Manager Motorcycle Europe, Goodyear, said, “We are proud to extend our partnership with FMI to support the continued growth of CIV, which is firmly established amongst Europe’s most competitive championships. In the past three years, we have worked closely with riders and teams at every level with a combination of proven and development tyres. CIV provides an unparalleled environment for our engineers to evaluate new technologies, as demonstrated by the development of our new KR111 front tyre. We look forward to continuing this work and bringing the benefits of our CIV partnership to even more riders.”

Giovanni Copioli, President, FMI, said, “We are delighted to announce the renewal of our partnership with Dunlop Motorcycle Europe as title sponsor of the CIV and exclusive tyre supplier to the Championship. Over the past three years, Dunlop and the CIV have built a highly successful relationship, contributing to the continued growth and development of the championship. The support of an industry leader such as Dunlop Motorcycle Europe has played an important role in this journey. Together, we are ready to embrace new challenges and continue raising the profile of the CIV, including further strengthening its international reach and appeal. I would like to thank Dunlop Motorcycle Europe for the trust, commitment and support it has shown throughout our partnership, and which it continues to provide as we look ahead to the future together.”
