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.”

Emerging as a direct answer to the mining industry's most persistent durability challenge, Triangle Tyre has comprehensively launched its groundbreaking giant OTR tyre bonding protection solution: EnsureX Efficient Technology. This innovation is specifically engineered for the world's most punishing environments, such as the Deo Nai coal mine in Vietnam's Quang Ninh province. There, extreme heat, prolonged humidity and rugged lignite terrain traditionally cause severe tyre ageing and delamination, leading to high failure rates and operational risk.

The core of EnsureX is a material science breakthrough that solves the critical problem of adhesion failure between rubber polymers and steel cords under heavy load and complex conditions. It centres on an ultra-high-performance cobalt-free bonding system paired with a gradient adhesion-layer distribution. This combination delivers transformative performance through three key pillars: exceptional fatigue resistance to handle constant deformation, enhanced ageing resistance that boosts adhesion strength by over 40 percent and long-lasting corrosion protection suited for harsh climates.

Already proven in rigorous field testing, the technology has been applied to 49-inch and 57-inch tyre series with remarkable results. It acts as a resilient mechanical anchor within the tyre's structure, deeply securing each steel cord to create a far more integrated and robust assembly. This engineering advancement reduces delamination failures by more than 95 percent and extends overall tyre service life by over 15 percent, directly addressing the costly cycle of premature scrapping.

The successful deployment of EnsureX Efficient Technology marks a significant leap forward in OTR tyre capability. By providing a stronger, more durable and stable solution, it not only elevates safety and efficiency for mining operations but also solidifies a new standard of performance through independent innovation in high-end tyre manufacturing.

CEAT Ltd reported strong growth in the December quarter, supported by higher volumes, improving operating margins and continued investment in capacity expansion, while flagging near-term pressure from currency movement and raw material costs.

The tyre maker posted consolidated revenue of INR 41.57 billion for the third quarter of FY26, up about 26 percent year on year. Standalone revenue rose 20.1 percent to INR 39.57 billion, driven by growth across replacement, OEM and international markets.

“This was a good Q3 for us, with more than 20 per cent year-on-year growth on a standalone basis,” said Arnab Banerjee, Managing Director and Chief Executive Officer. “Volume momentum continued across segments, supported by GST rationalisation, improving consumer sentiment and steady recovery in OEM demand.”

Demand outlook remains supportive

Management said the Indian tyre market entered calendar 2025 on a stronger footing, aided by tax reforms, rising electric vehicle adoption and premiumisation. CEAT expects the industry to deliver healthy single-digit growth over the medium term.

“Increasing disposable income in rural markets following robust rabi sowing and kharif harvest completion has been supportive,” Banerjee said, adding that replacement demand for truck and bus radials is expected to remain in the mid-to-high single digits, with seasonal upside during the summer months.

Two-wheeler tyres continued to perform strongly, while OEM demand for medium and light commercial vehicles recovered following GST rationalisation. Passenger vehicle demand is expected to grow at double-digit rates in the near term, supported by easing financing conditions.

International demand for radial commercial vehicle and passenger car tyres remained firm, with India emerging as a credible sourcing base for global OEMs and distributors.

Margins improve despite cost headwinds

Standalone EBITDA rose to INR 5.56 billion, translating into a margin of 14.1 per cent. Consolidated EBITDA stood at INR 5.68 billion, with margins improving both sequentially and year on year.

Gross margins, however, contracted sequentially by about 109 basis points, largely due to currency depreciation and inventory adjustments.

“The depreciation of the rupee and a modest rise in international natural rubber prices could result in a 1 to 1.5 per cent cost headwind over the next few quarters,” said Kumar Subbiah, Chief Financial Officer. “While crude-linked inputs remain stable, currency remains the key variable to watch.”

Standalone profit after tax came in at INR 1.92 billion, compared with INR 2.02 billion in the previous quarter. The decline reflected a one-time provision of INR 578 million linked to new labour code implementation.

“This provision largely relates to past service costs,” Subbiah said. “The ongoing quarterly impact going forward is expected to be minimal.”

Camso integration on track

CEAT said the integration of its Camso off-highway tyre business is progressing broadly as planned. Quarterly revenue stood at about USD 20 million, reflecting the ongoing transition of customer relationships from Michelin to CEAT.

“Most existing customers have approved the business transfer, ensuring continuity,” Banerjee said. “There are some one-time transition and IT costs in Q3, which will not recur from Q4 onwards.”

Management said underlying operating margins at Camso are already in double digits and are expected to improve further as utilisation rises and CEAT gains greater control over sourcing and sales.

Capex remains elevated

Capital expenditure during the quarter stood at INR 2.54 billion, taking cumulative spend for the year to INR 6.73 billion, excluding acquisition-related intangibles.

The board approved an additional INR 13.14 billion investment at the Chennai plant to add 3.5 million passenger car tyres of annual capacity, with completion targeted for the second half of FY28. The project will be funded through a mix of internal accruals and debt.

“Our capex guidance remains broadly in line with earlier estimates,” Subbiah said. “We will continue to monitor leverage closely to ensure balance sheet strength.”

Standalone gross debt stood at INR 29.54 billion, with debt-to-EBITDA improving to 1.25 times.

EV, premiumisation and sustainability

CEAT maintained a strong position in electric vehicle tyres, with more than 30 per cent share in OEM passenger EV tyres and about 20 per cent in two-wheeler EVs. The company continues to invest in premium products, including larger rim-size, run-flat and ZR-rated tyres, to improve realisations.

On sustainability, CEAT announced a partnership with CleanMax to develop 59 MW of hybrid wind-solar capacity, targeting about 60 per cent renewable energy usage by FY27.

“Q3 closed on a strong note, supported by a robust product pipeline and improving customer confidence,” Banerjee said. “We remain focused on sustaining growth while maintaining margin discipline and investing for the long term.”

Himadri Speciality Chemical Ltd reported a sharp rise in profit for the quarter and nine months ended 31 December 2025, supported by margin expansion and accelerating investment across speciality carbon black capacity, export infrastructure and downstream materials.

The Kolkata-based speciality chemicals group said profit after tax for the nine months rose to INR 5.6 billion, exceeding the full-year profit recorded in FY25. Earnings before interest, tax, depreciation and amortisation increased to INR 7.3 billion, reflecting stronger operating leverage and a shift towards higher value-added products, despite softer revenue.

Revenue for the nine-month period stood at INR 33 billion, while total sales volumes increased by about three percent year on year to 428,572 tonnes. The company said its product mix remained focused on speciality and application-specific offerings, supporting profitability amid market volatility.

For the December quarter, consolidated EBITDA rose about 12 percent year on year to INR 2.5 billion, while profit after tax increased 36 percent to INR 1.9 billion, underlining continued margin improvement.

Investment-led expansion remains central to Himadri’s growth strategy. During the quarter, the company commenced trial production at its brownfield speciality carbon black expansion project at Mahistikry. Once fully operational, the project will increase total speciality carbon black capacity to 130,000 tonnes per annum, positioning Mahistikry as the world’s largest single-site facility for speciality carbon black. The project involves an estimated capital expenditure of INR 2.2 billion and is aimed at premium applications including plastics, inks, coatings and other niche segments.

Himadri also commissioned a high-temperature liquid coal tar pitch terminal at New Mangalore Port, creating a second export corridor alongside Haldia on India’s eastern coast. During the quarter, the company executed its first export shipment of 3,600 tonnes of liquid pitch to the Middle East. Management said the new terminal enhances logistics flexibility, reduces concentration risk and supports export-led growth in coal tar derivatives.

Beyond core expansions, the company continues to deploy capital across multiple growth platforms funded largely through internal accruals. These include forward integration into speciality chemicals such as anthraquinone and carbazole, with planned capital expenditure of INR 1.2 billion, as well as phased investments in lithium-ion battery materials, including a lithium iron phosphate cathode active material plant targeted for commissioning from FY27.

During the quarter ended 31 December 2025, upon receipt of INR 2.4 billion in balance consideration from promoters, Himadri allotted one crore equity shares to the promoters. Following the allotment, promoter shareholding increased to 52.5 per cent.

Commenting on the performance, Anurag Choudhary, Chairman and Managing Director, said the results reflected disciplined execution, operational efficiency and steady progress on strategic investments. He said the commissioning of new capacities marks the beginning of the company’s next phase of growth.
