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.”

The German Rubber Industry Association (wdk) reported in Frankfurt am Main that used tyre disposal and recycling firms continue to face substantial shortages of used tyres, undermining a secure supply of secondary raw materials essential to a resilient and sustainable circular economy.

According to wdk Technical Director Stephan Rau, roughly 84,000 tonnes of used tyres were unaccounted for last year. These, and potentially far larger volumes, are suspected to have been exported outside the EU for incineration or pyrolysis under dire health and environmental conditions, removing them from German recyclers and the circular economy.

Although the loss rate has edged downward, the association argues that systematically recording waste tyres and their recycling pathways remains the most effective countermeasure. The wdk and allied organisations have urged this approach for years, describing it as easy to implement and capable of significantly strengthening the circular economy, provided political will emerges to support a functioning recycling system.

Rau also cited newly published statistics showing Germany generated 522,000 tonnes of waste tyres in 2025. Of that total, 210,000 tonnes became granules and rubber powder, now nearly triple the amount thermally recycled in the cement industry – a development the wdk called strongly positive, while noting that comprehensive quantity recording could enable substantially more tyres to be recycled.

Goodyear is presenting a collection of forward-looking concept and production vehicles at the Mondial de l’Auto Paris 2026 (Paris Motor Show 2026), taking place from 12 to 18 October at Paris Expo Porte de Versailles, highlighting how tyres shape automotive design. For over a century, the company has influenced vehicle appearance, performance and driver connection, with its Advanced Design Studio partnering with manufacturers to create tyres that complement design, reinforce brand identity and support future mobility.

Sebastien Fontaine, Lead Designer at Goodyear’s Advanced Design Studio in Luxembourg, has explained that concept vehicles require customised tyres forming part of a vehicle’s visual identity and supporting the car designer’s vision. Close collaboration with OEM design teams lets Goodyear create unique solutions from early development through public reveal, using laser-carving technologies, customised sidewall treatments and premium production platforms.

Opel’s Sports Tourer eXperimental Concept, displayed on the Opel stand, represents the next stage of the brand’s design philosophy and a bold vision for the electric estate of tomorrow. Its prominent ‘Opel Vizor’ face is accented by strong lighting signatures front and rear, while the side features fluid, technical surfacing, extendable diffuser elements and three-zone alloy wheels. The customised tyres, based on the Goodyear Eagle F1 Asymmetric and sized 285/35R22, were tailored to complement the concept’s athletic stance, with visual cues extending from rim to sidewall.

Peugeot’s RCZ Vision concept debuts as the latest expression of the ‘Feline Future’ design language, inspired by the RCZ Coupé produced between 2009 and 2015. It embodies a feline stance leaning forward, with defined shoulders and a light signature of three horizontal claws front and rear. Its electric architecture includes a solid-state battery and ‘X-by-Wire’ technologies, with 500 horsepower delivered through 21-inch front and 22-inch rear forged-aluminium wheels. Tyres based on the Goodyear Eagle F1 SuperSport, sized 255/35R21 and 295/30R22, feature a bespoke sidewall treatment connecting tyre to wheel and displaying the Goodyear and Eagle names.

Across the show, a wide range of production vehicles carry Goodyear tyres, spanning utility, sports, off-road, electric and petrol-powered models. These tyres are developed for efficiency, grip and durability, enhancing each vehicle’s capabilities. Highlights from Audi, Mercedes-Benz, Jeep, DS, Volkswagen, Lancia, Fiat, Renault and others can be followed on Goodyear’s social channels.

Goodyear’s concept vehicle presence extends beyond the current show. For decades, it has collaborated with manufacturers on visionary concepts through innovative tire designs and custom OE partnerships. Milestones include the 2013 Wingfoot Concept and the 2015 BH-03 Concept, which introduced ideas around energy generation and intelligent mobility. The 2016 Eagle-360 Concept, featuring a spherical tire design, challenged conventional thinking about autonomous mobility, was named one of TIME Magazine’s ‘Best Inventions of 2016’ and earned several design awards.

Later concepts including IntelliGrip, Eagle-360 Urban, Oxygene, Aero and reCharge explored artificial intelligence, autonomous transportation, sustainable materials, flying mobility and renewable tyre technologies, with several earning international design and innovation awards. More recent collaborations include the Citroën Skate Concept, Citroën Oli, Toyota Aygo X Prologue, Lancia PU+RA HPE, Opel Experimental and Peugeot Polygon.

The Alliance for the Future of Tires (AZuR) is organising the NRW Tire Recycling Forum on 10 November 2026 at the Lohrheide Sports Park in Bochum, running from 10:00 a.m. to 2:00 p.m. Held under the umbrella of the North Rhine-Westphalia Roundtable on Circular Value Creation, the free event targets municipal officials responsible for building, sports, green spaces, road and civil engineering, along with sustainability and climate protection managers.

Discarded tyres can be transformed into an array of construction materials, including impact-absorbing sports surfaces, sound and vibration insulation and protective layers for green roofs and photovoltaic installations. The gathering will examine how municipalities can integrate such recycled goods into their infrastructure and building projects.

Expert presentations, real-world case studies and details on funding programmes for urban development and sports initiatives across North Rhine-Westphalia form the core of the agenda. Public procurement will receive particular attention, with discussion centring on how technology-neutral, quality-focused tendering can encourage greater adoption of suitable recycled products in municipal work.

A guided tour of the Lohrheide sports park's newly installed running track, which contains tyre rubber granulate, serves as a principal attraction. Attendees will learn about the material's characteristics, the construction process and lessons drawn from planning, tendering and execution, offering concrete evidence of mechanical tyre recycling within a functioning circular economy. The event also connects to North Rhine-Westphalia's new circular economy strategy, which treats used tyres as a distinct field of action.

BendPak’s Ranger Division has introduced the DST30PX, a next-generation wheel balancer in its DST Series, built to help shops handle larger OEM wheel assemblies and heavy aftermarket truck tyres. Older balancing platforms can struggle with these oversized wheels, slowing service and creating bottlenecks. The DST30PX addresses those issues through a new hood design, a larger shaft and an overhauled structural chassis.

The robust hood accommodates a wider range of tyre shapes and sizes, including oversized off-road and fleet tyres, without time-consuming repositioning. Its open-side design lets wider tyres, aggressive offsets and bulky sidewalls slide in more easily, cutting setup time and allowing operators to position wheel assemblies up to 43 inches in diameter. Ranger reinforced the chassis and hood assembly to handle added mass without flexing, compromising alignment or generating excess vibration, supporting consistent measurements and reliable accuracy. The rugged 40 mm shaft increases stiffness and accuracy for heavier wheels.

A large, 64-tooth magnetic transducer encoder with precision-cut square teeth converts rotary position into a digital electronic signal, helping achieve accurate profile readings and top-dead-centre positioning for minimal, precise wheel placement. This extra resolution benefits modern wheels requiring cleaner correction, smaller weight changes and better placement accuracy. The DST30PX also streamlines repetitive service through simple wheel data entry, precise rolling weight readings, automatic braking, manual or automatic hood-start operation and rapid cycle times. A quick-release hub nut, side-position brake, top-dead-centre weight indicator and tiered placement indicators accelerate setup and correction, while onboard storage includes a top tray, side cone pegs and a side shelf for Ranger Quick-Peel adhesive tape weight rolls.

Key features include a 145-lb (approximately 65 kg) capacity, a 30-inch wheel diameter range, a 43-inch maximum tyre diameter, low-RPM operation, a six-second cycle time, Dynamic, Static and Performance Alloy settings, a 16-bit processor, multi-directional quartz piezoelectric sensors, a multi-user save function with presets, ergonomic controls and a full-tilt LED display control panel. The DST30PX suits shops seeking higher precision, faster workflow, and advanced measuring for modern wheels without moving to a larger premium machine. It is ETL certified to applicable UL and CSA safety standards in the United States and Canada, ships with a starter kit of adhesive and clip-on steel wheel weights and offers Ranger Select setup and training.

Sean Price, Director of Product Development, BendPak, said, “The Ranger DST30PX represents a fundamental shift in how modern shops handle today’s radically heavier, oversized wheel configurations. It ensures technicians can mount, spin and perfectly balance oversized assemblies without a single second of wasted motion.”
