Tyre Testing: The Nitty-Gritty And The Future

Bajaj Auto Launches Touring-Ready Dominar 400 At INR 2.17 Lakh

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.”

Enviro Disputes Infiniteria’s Request To Terminate Company Reorganisation

Enviro Disputes Infiniteria’s Request To Terminate Company Reorganisation

Scandinavian Enviro Systems AB (publ) has disputed a request from Infiniteria Sweden AB and Infiniteria Europe Sàrl to terminate the company’s ongoing reorganisation. In a statement submitted to the Gothenburg District Court on 22 April, Enviro argued no grounds exist to end the process, originally approved on 27 February 2026. A creditors’ meeting on 18 March saw no opposition to the reorganisation continuing.

The dispute stems from Enviro’s decision to terminate the joint venture agreements with Infiniteria under Swedish law, calling them burdensome and loss‑making. Infiniteria filed a termination request on 15 April, which Enviro answered on 22 April. Enviro disputes the request and several supporting claims.

Enviro states the joint venture caused its financial difficulties, while its business plan shows opportunities to build a profitable enterprise using its patented technology. Infiniteria has asserted a preliminary damages claim of approximately EUR 84 million, but Enviro notes the claim is unsubstantiated and partially overlaps with ongoing arbitration announced on 6 February.

Enviro points to contractual liability caps, including EUR 3 million in the marketing and agency agreement and EUR 2 million in the license agreement. Infiniteria has not shown why these caps should not apply. Regarding the license agreement under English law, Enviro maintains termination was lawful, meaning Infiniteria’s exclusive right to Enviro’s technology has ceased.

Despite the legal conflict, Enviro reports strong global interest. A North American feasibility study is progressing faster than expected, and licensing dialogues are ongoing with around 10 stakeholders. Enviro remains determined to build long‑term value without the former joint venture’s constraints.

Hankook Tire’s New Film Rewinds Formula E Action To Spotlight EV Tyre Technology

Hankook Tire’s New Film Rewinds Formula E Action To Spotlight EV Tyre Technology

Hankook Tire has released a new brand film titled ‘Formula E Rewind’, inspired by the ABB FIA Formula E World Championship. The company serves as the exclusive tyre supplier for the global all-electric racing series, which is organised by the Fédération Internationale de l’Automobile. The latest cinematic work follows a previous Formula E brand film introduced in April last year.

That earlier production focused on Hankook’s advanced motorsports technologies and research supported by cutting-edge infrastructure. Its high production quality earned a Silver Prize in Sound Design at the Seoul Video Advertising Festival 2025, one of South Korea’s largest advertising awards. The newly unveiled film employs a distinctive rewind visual technique, shifting attention from racing outcomes back to the origin of technology. It emphasises that every race starts with the tyre while promoting the innovative ‘iON’ brand, the world’s first full lineup of electric vehicle tyres.

The film dynamically showcases the next-generation electric racing machine GEN3 Evo, which reaches 322 kilometres per hour and accelerates from zero to 100 kilometres per hour in just 1.86 seconds. It also features the official electric racing tyre ‘iON Race’, delivering a powerful sense of speed. By reconstructing race sequences in reverse, the video creates a fresh narrative that boosts viewer immersion. The slogan ‘Where it all begins’ and a composite logo reinforce Hankook’s positioning as a key Formula E partner.

The brand film will be distributed across Hankook’s owned media platforms, including its global website, YouTube and Instagram, aiming to engage motorsports fans, EV users and future mobility consumers.

Solvay’s Predictive Maintenance Push Gains Speed With Expanded IMI Agreement

Solvay has significantly expanded a global framework agreement with IMI, accelerating the installation of connected industrial sensors throughout its worldwide manufacturing network. Under the extended partnership, IMI remains Solvay’s preferred supplier, with over 5,000 sensors already deployed across 25 sites in 11 countries. The ongoing rollout is enhancing operational reliability and efficiency while simultaneously lowering costs and reducing the company’s environmental impact.

The connected devices, classified as Industrial Internet of Things sensors, continuously monitor vibration and temperature on critical machinery. This real‑time data allows Solvay teams to track asset performance, prevent unexpected breakdowns, and schedule maintenance precisely when needed. The group intends to expand the sensor network to 9,000 units by 2027, reinforcing its shift from traditional time‑based maintenance to a predictive, data‑driven approach.

This sensor initiative is central to Solvay’s Essential for Generations strategy, which prioritizes operational excellence and sustainability. By leveraging real‑time information, the company predicts equipment failures, cuts repair expenses, and limits energy losses and waste. Having scaled from just a few hundred sensors in 2023 to more than 5,000 installed globally, Solvay is building a more resilient and reliable industrial footprint across all regions.

Lanny Duvall, Chief Operations Officer at Solvay, said “Digitalisation is reshaping the way we run our plants. Expanding the use of connected sensors helps us make quicker and better-informed decisions that improve safety, reliability and energy efficiency – while also making our operations more competitive and cost‑effective. It’s a concrete accelerator of the operational excellence transformation we’re driving across Solvay as part of our Essential for Generations strategy.”

Diana Garcia, Global Business Development Manager, Digital Products at IMI, said, “The complexity of modern plant operations, coupled with constant pressure on margins, means the chemical industry cannot rely on manual inspections to ensure maintenance operations are efficient and effective. Our technology provides realtime insights that support Solvays move towards predictive maintenance. We are pleased to deepen this successful collaboration.”

Nexen Tire America Outlines Early-Stage Collaboration As New Standard For OE Tyres

Nexen Tire America Outlines Early-Stage Collaboration As New Standard For OE Tyres

Nexen Tire America has detailed how original equipment tyre development has shifted from a standalone process to an integrated engineering effort conducted alongside new vehicle design. The company explains that modern vehicle complexity, driven by electrification and advanced driver systems, requires tyre engineering to begin in parallel with suspension, chassis and electronic control development. This earlier collaboration allows tyre performance to be optimised for hybrid and electric vehicle demands such as noise reduction, load capacity and rolling resistance.

Aaron Neumann, Head of the Nexen Tire America Technical Center, describes how suppliers must now adopt faster development cycles and deeper technical collaboration. The traditional model of selecting off-the-shelf tyres has been replaced by purpose-built designs tuned to specific safety, handling and efficiency targets. Electric vehicles have added further criteria including range optimisation and tyre noise mitigation.

To manage these demands, Nexen has expanded its use of simulation and modelling technologies. Finite element analysis and data-driven tyre modelling allow engineers to evaluate performance early in the development cycle, reducing the number of physical prototypes required. Despite this digital focus, physical testing remains extensive and includes laboratory procedures such as high-speed endurance, rolling resistance, uniformity, noise and flat-spotting assessments.

On-road validation involves instrumented traction and braking tests, ride and handling evaluations, treadwear analysis and durability testing across varied surfaces and climates. Each tyre’s tread pattern, construction, footprint and profile are refined through iterative testing specific to the target vehicle. While some materials overlap with replacement tyres, original equipment fitments are engineered to balance performance, efficiency and comfort.

Over the past decade, Nexen Tire has more than doubled its original equipment portfolio in North America. This growth is attributed to an engineer-to-engineer collaboration model emphasising transparency and responsiveness. Many technologies developed for original equipment programmes, including advanced compounds and tread designs, are later incorporated into replacement tyres.

For consumers, these behind-the-scenes engineering efforts result in tyres more precisely matched to vehicle performance. Neumann notes that modern tyres rank among the most complex vehicle components, having to deliver safety, efficiency and comfort simultaneously across a wide range of conditions, even if that complexity remains largely invisible to drivers.
