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.”

A new study from the California Office of Environmental Health Hazard Assessment (OEHHA) has concluded that crumb rubber infill made from recycled tyres and used in synthetic turf fields poses no significant health risk to those who use or observe them. The comprehensive evaluation found no evidence linking these fields to cancer or other health issues for athletes, officials, coaches or spectators, including young children.

These engineered fields, designed to replicate natural grass, are popular due to their low maintenance, water efficiency and durable, consistent surface. Their widespread adoption in California includes over 900 installations. The infill itself consists of small granules from recycled waste tyres, which help keep the artificial blades upright and provide cushioning and traction.

OEHHA conducted the study to support California's sustainability efforts, specifically its Waste Tire Program, which seeks safe and beneficial uses for recycled materials that would otherwise go to landfills. To ensure a thorough assessment, researchers tested 35 different fields, varying in age and location to represent all of California's climate zones. Multiple samples were taken from each field to account for material differences, and air quality was monitored both during active play and at rest.

The study’s scope was unprecedented, analysing over 100 chemicals of potential concern, far more than previous investigations. In collaboration with Lawrence Berkeley National Lab, researchers simulated human sweat and digestion to identify all chemicals to which a person might be exposed. To understand exposure pathways, OEHHA partnered with UC Berkeley and the University of Arizona. They surveyed over a thousand soccer players, ranging in age from 7 to 71, about their playing habits and observed games to document contact with the turf. The analysis used data from goalies, who have the most frequent contact, to estimate the maximum risk for all players, also considering the potential exposure for a crawling toddler. The final analysis indicated that risks related to cancer, reproductive harm or sensory irritation were negligible.

Kris Thayer, Director, OEHHA, said, "This study should ease concerns about the safety of crumb rubber use in synthetic turf fields. Athletes of all ages can use these fields without parents worrying about this commonly used material."

Zoe Heller, Director, CalRecycle, said, "Protecting public health is our top priority, and California is committed to making sure waste tyres are managed safely so they don’t litter communities or pose risks to residents. CalRecycle appreciates the work of OEHHA and its partners to advance our understanding in support of a cleaner, healthier circular economy."

The all-new Vredestein Quatrac Pro 2, an ultra-high-performance (UHP) all-season tyre scheduled for launch this summer, will come armed with a next-generation tread compound technology and a highly innovative structure to deliver an unrivalled combination of year-round safety, performance and efficiency across dry, wet and winter conditions. This model represents a major advancement for the Vredestein brand, which has been a pioneer in the all-season sector since the early 1990s.

Developed from a clean sheet by Apollo Tyres at its Global R&D Centre in the Netherlands, the Quatrac Pro 2 was not an evolution of an existing design. Instead, engineers completely reimagined the tread, materials and structure to overcome the typical performance compromises found in this category. The tyre will be manufactured at Apollo’s advanced facility in Hungary.

The core of its capability is a new directional tread pattern. Longitudinal grooves work with a V-shaped design to maximise resistance to aquaplaning by efficiently evacuating water. Lateral grooves are sculpted to harmonise wet-road performance with winter traction, while a stable centre rib ensures precise dry handling and braking stability on both wet and dry surfaces. For snow-covered roads, advanced 3D interlocking sipes in the shoulder blocks provide grip without compromising tread stability in other conditions. A multi-pitch tread block sequence also refines the acoustic signature, which is particularly advantageous for electric and hybrid vehicles. The entire Quatrac Pro 2 range achieves an A-rated exterior noise label.

A revolutionary next-generation traction compound is central to the tyre’s versatile performance. This advanced material combines a unique mixture of resins and polymers with complex multi-filler technology. The result is a tyre that maintains a broad operational range across varying temperatures, with a strong emphasis on wet braking. It balances low-temperature flexibility for reliable grip on cold, wet and snowy surfaces with high-temperature stability for consistent handling and abrasion resistance on hot, dry roads, enhancing durability year-round. The tyre bears the Three Peak Mountain Snowflake (3PMSF) symbol, confirming its winter capability.

This new compound and tread design are also optimised for electric and hybrid vehicles, managing the challenges of high battery mass and instant electric motor torque by ensuring consistent grip and tread stability. The engineering goal was to provide high levels of cornering stability and precision without sacrificing ride comfort, a balance that sets the tyre apart.

Complementing the compound, the tyre's structure has been entirely re-engineered. A stiffer bead area with a double taper design ensures secure bead seating even at high speeds while distributing forces more evenly for improved comfort and stability. A dedicated belt design optimises the tyre's footprint for enhanced mileage. In mixed fitments, this improves steering precision at the front axle and stability at the rear.

The Vredestein Quatrac Pro 2 will be available in an extensive range of sizes for 17- to 24-inch rims, including section widths up to 355 for high-performance vehicles. With speed ratings up to Y (300 kmph), it firmly positions itself at the pinnacle of the UHP all-season category, with high load rating options on select sizes.

Daniele Lorenzetti, Chief Technology Officer, Apollo Tyres Ltd, said, “The Quatrac Pro 2 has exceeded the very demanding performance target we set during development while delivering superior wet grip, great snow handling, low rolling resistance and high mileage. By focusing on the fundamentals of tyre behaviour and rethinking tread design, materials and structure, we have created a performance-focused all-season tyre that delivers stability, mileage, all-season grip with best wet performance in category.”

Pirelli is all set for the Chinese Grand Prix, which marks the first Sprint weekend of the 2026 Formula 1 season and will see the presentation of the newly redesigned Pirelli Sprint Qualifying Award. The second round of the championship will feature a 19-lap short race on Saturday, the first of six such events scheduled for the year.

The tyre allocation for the event remains unchanged from previous years, with teams supplied the C2, C3 and C4 compounds for the 5.451-kilometre Shanghai International Circuit. The track layout, inspired by the ‘shang’ ideogram, includes two primary straights and sixteen corners. One notable straight connects a slightly banked Turn 13 to Turn 14, while the other, which exceeds one kilometre in length, is where the starting grid is situated.

The circuit presents a varied challenge with a mix of high-speed corners, such as the sweeping Turns 7 and 8, and slower sections found at Turns 1, 3, 6 and 14. These demanding sequences, combined with fast straights, place significant stress on the tyres and will test the energy recovery capabilities of the new power units. Drivers may face difficulties with corner-entry lock-ups under heavy braking, similar to issues observed during pre-season testing in Bahrain, which features comparable braking zones.

A key variable for the weekend is the track surface, which was completely resurfaced in August 2024. The new asphalt initially provided higher grip and lower lap times, but its smoothness led to front-axle graining during the 2025 event, particularly in the Sprint race. However, as the surface has had another year to age, grip levels might be slightly reduced, potentially lowering the risk of graining. This will be assessed in early practice sessions. Teams’ simulation data suggests lap times will be closely matched to last year’s, indicating that the performance loss expected from the new car generation may be offset by other factors.

Looking back at the 2025 race, most drivers started on the Medium compound, with only three opting for the Hard. The Soft tyre was unused in the Grand Prix. The winning strategy was a one-stop, featuring a long final stint on the Hard tyre, which proved durable and resistant to graining. The podium finishers made their sole pit stops between laps 14 and 15, with Oscar Piastri taking victory ahead of Lando Norris and George Russell.

The trophy for the pole-sitter features a Soft tyre above a base embedded with a helmet decorated in the colours of the Chinese flag, which will be engraved with the winner’s name and car number. The Chinese Grand Prix returns for its 19th running at this venue, having first appeared on the calendar in 2004. Lewis Hamilton and Mercedes share the record for the most wins here, with six each. Hamilton also holds the record for the most podium finishes, with nine.

To celebrate the event, a special podium cap has been created in imperial yellow, a colour traditionally associated with prestige. It features designs commemorating the Year of the Horse and will be available for purchase on the Pirelli e-commerce platform.
