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.”

TyreSafe has announced a new alliance with Logistics UK, marking a significant step in uniting efforts to enhance road safety, promote sustainable transport and disseminate best practices within the freight and haulage industry. This collaboration formalises the mutual dedication of both organisations to address critical safety challenges facing UK's transport networks.

Logistics UK, a prominent membership association representing over 21,000 enterprises, encompasses the breadth of the supply chain, including road, rail, water and air freight. Its extensive network accounts for nearly half of the national lorry fleet, comprising more than 200,000 vehicles. Through advocacy, training and compliance support, the organisation is instrumental in maintaining secure and efficient supply chains, making it a pivotal partner for TyreSafe's safety initiatives.

The partnership underscores the growing recognition of tyre management as a cornerstone of modern logistics, impacting not only vehicular safety but also operational costs and environmental footprints. Data indicates that a majority of tyres on UK roads are underinflated, leading to approximately GBP 1 billion in annual fuel waste and accelerating tyre degradation. Furthermore, tyre defects are a primary cause of MOT failures, with over two million infractions recorded yearly, and they contribute significantly to roadside breakdowns and motorway incidents.

For commercial fleets, the stakes are particularly high, as proper inflation and tread depth are directly linked to fuel economy, emissions reduction and cost efficiency. As part of this joint effort, TyreSafe will promote its specialised, vehicle-specific safety resources, offering tailored guidance for HGVs, vans and cars. This educational push aims to empower drivers and operators with the knowledge to conduct effective tyre checks, thereby mitigating risks and supporting the logistics sector's sustainability and operational goals.

Stuart Lovatt, Chair of TyreSafe, said, “We are delighted to be partnering with Logistics UK, an organisation that shares our commitment to safer, more sustainable and more efficient transport. Tyres and their maintenance absolutely fundamental to fleet safety and performance. This partnership allows us to extend vital tyre safety messaging to a broad and influential logistics audience at a time when operators are balancing safety, compliance, cost pressures and sustainability ambitions. By working together, we can help ensure tyre safety remains firmly on the agenda across the sector.”

Arthur Gribbin, Engineering Policy Lead at Logistics UK, said, “Efficient logistics depends on vehicles operating safely, legally and reliably. Tyres play a critical role in achieving this, influencing everything from vehicle safety and fuel efficiency to downtime and environmental impact. By partnering with TyreSafe, we are helping ensure our members and the wider logistics community have access to trusted information and practical guidance to support safer and more sustainable fleet operations.”

AZuR partner Hofdmann Runderneuerungstechnik GmbH, based in Wittmund, has announced a significant expansion of its operational capabilities. The company, already well-known for its cold retreading services, is now integrating hot retreading for truck tyres into its production portfolio. This development follows the recent extension of the firm’s ECE R109 approval, and the first batches of hot-retreaded commercial vehicle tyres are already in production and entering the market.

This strategic move broadens Hofdmann’s technical expertise within the retreading sector and reinforces the tyre circular economy across Germany. As a longstanding member of the AZuR network, the company contributes deep knowledge in tyre repair, casing management and retreading processes. The addition of hot retreading complements the prevalent cold retreading method used in the commercial vehicle industry, offering enhanced options for specific tyre designs and applications, while both methods aim to extend the lifecycle of premium casings.

By diversifying its production programme, Hofdmann demonstrates that industry players are actively investing in retreading technologies and strategically scaling existing operations. This expansion not only bolsters the sector’s competitive position but also ensures a more reliable supply of retreaded tyres for fleet operators and commercial end-users. The process involves meticulous inspection of high-quality used casings before applying a new tread, significantly prolonging tyre usability prior to eventual material recovery or recycling.

The company’s capacity growth coincides with broader AZuR initiatives, including a recently launched European project group designed to strengthen collaboration among businesses, research bodies and value-chain stakeholders. With approximately 90 network partners, AZuR continues to pioneer solutions for maximising tyre usage and recovering raw materials. Hofdmann’s latest investment underscores that retreading remains a vital and enduring component of this sustainable industrial evolution.

Christina Guth, Network Coordinator of the Alliance for the Future of Tires (AZuR), said, “Every investment in retreading strengthens the European tyre circular economy. By expanding its hot retreading capabilities, Hofdmann is broadening its offering and creating additional opportunities to keep high-quality commercial vehicle casings in circulation for longer. This sends an important signal to the entire industry.”
