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's 23-season run as sole official tyre supplier to the FIM Superbike World Championship ended at Jerez de la Frontera during the Pirelli Spanish Round. The Italian manufacturer helped shape the technical identity of the premier production-derived series through continuous product development and innovation while emphasising tyre safety and reliability and cooperating closely with organisers, the federation, manufacturers and teams.

The firm's connection to production-based motorcycle world championship racing dates back to 1989, when it debuted with the Rumi team's Honda RC30 ridden by reigning world champion Fred Merkel. The American narrowly missed the podium at Donington Park but took pole and won both Hungaroring rounds, putting him on course to defend his crown. After withdrawing from major motorcycle racing championships in the 1990s, Pirelli returned in 2004, when the WorldSBK promoter chose it as sole official tyre supplier under an arrangement that marked a turning point in international motorsport.

The company's strategy was straightforward: turning racing into a genuine development laboratory for motorcyclists. In a championship built on production-derived machines, that meant supplying tyres closely resembling products available to the public rather than solutions created exclusively for competition. Pirelli pursued innovation that progressively redefined racing tyre performance and then fed track knowledge back into its road products.

The DIABLO Superbike, launched in 2005, became a benchmark in the racing slick range, and the DIABLO Supercorsa followed in 2007 for support classes, leading in 2008 to the DIABLO Supercorsa SP road tyre. The SC0 compound arrived for the DIABLO Superbike in 2012 and reached the road range a year later. Rims changed from 16.5 to 17 inches in 2013, and 125/70 front and 200/65 rear sizes were introduced in 2018, followed by the SCX supersoft compound in 2019 and the SCQ extrasoft compound in 2022. From 2020, every class ran on slicks.

Across those 23 seasons, Pirelli's role grew into a proactive partnership supporting the championship's development, producing close relationships first with Infront and later with Dorna that extended to marketing and communication. Initiatives originally conceived for Pirelli's guests were gradually opened to the entire paddock, making the championship more attractive for supporters and a wider audience.

The 2026 season underlined that approach, with Pirelli offering riders 17 front and rear solutions combining standard range products with development specifications. The effort brought constant performance gains and fresh milestones, including 10 all-time lap records and 11 race lap records alongside significant race distance improvements. The journey spanned from James Toseland, the first world champion of the Pirelli era in 2004 aboard the Ducati 999 F04, to Nicolò Bulega, who dominated 2026 on the Ducati Panigale V4 R with wins in 36 races. As this chapter closes, the accumulated knowledge will continue to drive Pirelli's tyre development and its commitment to the highest racing levels.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “We have developed racing and road tyres for more than two decades. Although our journey in WorldSBK is coming to an end, we will continue to innovate our racing products to boost on-the-road technology and performance. For more than two decades, we turned WorldSBK into an innovation lab and helped organisers, the federation, manufacturers and teams in its evolution. By constantly creating and fine-tuning new compounds, structures and solutions, we have boosted performance and set new records year after year while also generating technology and expertise that went on to be transferred to road tyres. We pursued this quest right through the final season, and it does not end here: the experience gained in WorldSBK will continue to drive Pirelli's leading edge both in motorsport and on the road.

“Despite operating under a single-tyre supplier system and always providing competitive products, our goal has consistently been to improve our game, year after year, by offering state-of-the-art products while paying extremely close attention to market demands. This was especially true in the early years, when end users wanted and needed a pure racing product they could use on the track. We recognised that need, by continuing to develop increasingly better products, and, most of all, by introducing new race-to-road sizes, which became the new benchmark for the sports motorcycles on the market.”

Prinx Chengshan took part in the SHACMAN Group Worldwide Partnership Conference in Xi'an on 15–16 October, where dealers, key accounts and industry partners from across the globe gathered. The company attended as a core strategic partner of SHACMAN and acted as exclusive tyre sponsor of the vehicle stunt show, joining domestic and international customers to examine fresh opportunities in the global commercial vehicle sector and help shape a new model of collaborative industry growth.

Cooperation between the two firms has deepened since 2024, centring on original equipment fitment for flagship high-end models including the Delong X5000 and X6000, with products offered domestically and overseas. Dependable product quality and supply chain assurance have enabled Prinx Chengshan to grow into a core tyre supplier to SHACMAN, consistently furnishing tyre solutions for its flagship ranges.

A dedicated stunt driving segment formed part of the conference, with Prinx Chengshan as sole tyre exhibitor backing the performance vehicles. Cars fitted with Chengshan XSTANCE PRO S10 and CDR621 tyres carried out sustained drifts, high-speed turns and other demanding manoeuvres, remaining stable even under extreme conditions such as tyre burnouts and showing strong wear resistance.

Li Wenli, a three-time national truck racing annual finals champion known as China's top heavy truck driver, rated the tyres highly for grip, durability and handling stability. Live demonstration in place of specification presentations made technical strengths tangible, letting partners observe stability under extreme friction and high-torque loads.

The conference allowed the company to strengthen mutual trust and communication with SHACMAN and to showcase its commercial vehicle tyre capabilities; at its 50th anniversary milestone, Prinx Chengshan reiterated its commitment to keep improving its global service network, advance alongside SHACMAN on a new globalisation journey and help build an industrial ecosystem defined by mutual benefit and collaborative development.
