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.”

Bridgestone has issued a comprehensive advisory for motorists confronting the perils of summer heatwaves, which present significant challenges for both drivers and their vehicles. The combination of scorching tarmac, fully laden holiday luggage and extensive motorway travel can subject tyres to extraordinary strain. In response, the tyre manufacturer has outlined essential precautions to enhance road safety during elevated temperatures.

When temperatures climb beyond 30 degrees Celsius, the company emphasises the need for drivers to prioritise personal wellbeing. Adequate hydration and regular respite are paramount, as excessive heat can impair concentration and slow reaction times. Experts suggest scheduling a break at least every two hours, while seeking shaded parking areas is recommended to curb heat accumulation inside the vehicle.

Beyond passenger comfort, Bridgestone highlights critical technical considerations for hot weather. Tyres are particularly susceptible to added stress, prompting the company to urge pre-trip inspections. Prior to lengthy excursions, tyre pressure should be checked when cold, as heavier holiday loads require adjustment. Under-inflation can exacerbate heat generation, adversely affecting wear, stability and braking distances, with specific pressure guidelines often available for laden vehicles.

Driving behaviour requires modification under these conditions. High speeds on hot road surfaces generate significant additional heat within tyres, a risk that escalates with a full vehicle or trailer. Bridgestone counsels motorists to moderate speed and adopt a smooth driving style. A visual inspection for cracks, bulges or embedded debris is also imperative, as high temperatures intensify the effects of damage, with older tyres being especially vulnerable.

The advisory also addresses unpredictable summer weather, where heatwaves can abruptly give way to thunderstorms and heavy rain. The sudden shift from hot tarmac to a wet surface places tremendous demands on tyres and drivers. Maintaining sufficient tread depth and equipping the car with high-performance summer tyres is essential for effective water dispersal and control during these sudden changes.

Bridgestone points to its Turanza 6 tyre as a solution for these demands, offering excellent wet grip and short braking distances on wet roads. This premium touring tyre also provides enhanced driving comfort, improved mileage and optimised fuel efficiency. Motorists can therefore navigate changeable summer weather with heightened confidence and peace of mind.

Andy Mathias, Head of Marketing, North Europe, said, “The high temperatures we are currently experiencing in many parts of Europe pose particular challenges for drivers and vehicles. This makes it all the more important to pay special attention to road safety. With well-maintained tyres, regular checks and anticipatory driving, motorists can significantly improve their own safety and that of their passengers.”
