In an era of heavier vehicles, rising torque loads and ever-larger wheel diameters, the tyre-wheel assembly (TWA) has quietly become one of the most critical systems influencing vehicle safety, durability and perceived quality. Yet for most consumers, it remains entirely invisible. According to Luc De Bruyne, OEM tyre-wheel assembly R&D specialist in the Department of Manufacturing and Innovation at Eurofit, that invisibility is precisely why the industry underestimates its importance.

Based in Zaventem, Belgium, the company operates as a high-precision service supplier for tyre–wheel assembly, focused on passenger cars and light trucks in the European market. It runs a network of 16 factories, supported by around 900 employees, and delivers a full set of assembly and logistics services. With an annual capacity of roughly 20 million tyre–wheel assemblies, production is supplied to more than 25 OEM locations across Europe.

From an OEM perspective, De Bruyne argues that tyre-wheel assembly can no longer be treated as a simple fitment task. “Due to the increase of load and power transmission of the cars, a correct seating of the tyre bead is more sensitive. The increased bead tension can result in a damaged tyre during mounting, which isn’t visible at the outside. A damaged bead can result in leakages and low-pressure during driving, which is a high risk of a safety issue during high-speed driving. In other words, what appears externally acceptable may already be compromised internally,” he explains.

This growing complexity is not adequately addressed by existing standards. While ETRTO, ISO, ASTM and JASO regulate individual components, there is no global standard governing the assembled wheel. In practice, this means quality depends heavily on internal OEM processes. As De Bruyne notes, “A TWA assembler must mount the components together with no damages to the product and the lowest level of risk of vibration on the car.” To achieve this, Eurofit and its partners develop internal process references with machine suppliers, such as mountability and integrity tests used to qualify new wheels. When a non-OK status is detected, suppliers are informed, and if no solution is found, components may be replaced entirely.

The business is structured as a longstanding 50:50 joint venture between Michelin and Continental, established in 1996. This partnership combines the technological depth, quality standards and global experience of two of the world’s leading tyre manufacturers. The JV structure underpins strong process discipline, continuous improvement and long-term stability for OEM customers.

The technical challenge intensifies as wheel sizes increase and tyre profiles become lower. Larger diameters bring not only harsher ride characteristics but also tighter tolerances across mounting, uniformity and balancing. De Bruyne outlines a suite of measures now required for high-performance wheels: checking rim run-out and match points to filter supplier deviations; guiding the tyre bead diagonally to reduce mounting forces; matching components to lower total uniformity (TU) levels; optimising bead seat geometry; measuring complete wheel run-out to achieve what he calls the ‘perfect circle’ and correcting balance through final audit controls linked to vehicle sensitivity. The payoff is clear – less vibration of a wheel results in a longer lifetime of the tyres and suspension system of the car.

The contrast between OEM-assembled wheels and typical aftermarket replacements remains stark. In Europe, De Bruyne identifies two aftermarket models. The first involves high-volume industrial assembly of wheel kits – often winter packages – using processes similar to OEM plants. “We recommend to order wheels from such entity to receive an upper grade quality level compared with the garage machine assemblers,” he says. The second model is the small local tyre shop, where limitations are far more pronounced. These workshops often use grade 2 or 3 tyres rather than the grade 1 tyres supplied to OEMs, apply grease-based lubricants forbidden in Tier 1 environments, rely on manual mounting without force control, inflate tyres without proper bead seat techniques and balance wheels on single machines without controlling clamping-device influence. “The manual mounting approach can result in a higher risk of vibration/sound level of the wheels to the car/driver/passenger,” De Bruyne warns. For OEMs, the objective is clear: the first test drive of a new car must feel fundamentally different from that of a used one.

Electrification has further raised the stakes. Higher torque loads and quieter powertrains mean that any wheel-induced vibration is far more noticeable. “Observation of increase of torque load on cars results in increase of tyre bead tension,” De Bruyne explains, along with higher surface roughness requirements on rim bead edges. Assembly processes now demand stricter control of mounting forces and higher-energy inflation using inflator bells. After inflation, micro bead correction is required to ensure full contact and maximise friction. Lubrication, meanwhile, must leave no residual grease, as this could allow bead slip under extreme acceleration or braking.

Eurofit’s position as an industrial service provider rather than a component manufacturer reflects broader shifts in vehicle production. A generation ago, car manufacturers assembled most parts themselves. “Due to the increase of complexity and need of assembling volume and faster cycle time of cars, a lot of key-assembling activities are outsourced,” De Bruyne says. This has freed space within vehicle plants, increased model variants and created demand for specialist know-how. Tier 1 component suppliers now deliver globally to wheel assembly plants located close to OEMs, enabling just-in-time supply with greater flexibility.

Logistics has evolved accordingly. Classic JIT lines are increasingly supplemented – or replaced – by batch production, sequencing centres and high-bay warehouses. De Bruyne describes specialised processes that keep wheels sequenced all the way to the OEM, including racks and trailers with walking-floor systems for direct unloading. Over the past 20 years, the explosion in variants has driven major upgrades in logistics software and product traceability. Such systems require constant monitoring and rapid deviation management to avoid production stoppages at the customer.

Despite all this, wheel assembly remains largely invisible to consumers – at least for now. De Bruyne believes this may change as EVs become dominant. With fewer vibration sources from engines and transmissions, wheel-induced disturbances move ‘on the horizon’, particularly as XL tyres and extreme sizes – up to 25 inches – enter production. Some manufacturers, he notes, are already upgrading assembly specifications in response to negative customer feedback on ride performance.

Replicating OEM-level quality outside factory environments remains difficult. OEM assemblers must meet manufacturer-specific specifications that are neither public nor economically viable for most aftermarket operations. While some garage-machine suppliers now offer optional TU, run-out and matching functions, De Bruyne is blunt: accuracy, repeatability and production speed remain poor, and costs are high. Where large aftermarket organisations adopt industrial processes for volume reasons, conditions may resemble OEMs, but ‘the difference is the respect of process limits’, which are typically broader and not tied to a single vehicle programme.

Balancing tolerances illustrate the point. OEM plants may work to residual imbalances as low as two grammes, while many workshops accept eight to 15 grammes. Whether a driver notices depends on vehicle sensitivity, but the physics are unforgiving. “Imbalance vibrations can increase very fast when the speed is going up due to the exponential behaviour,” De Bruyne notes. Lower residual imbalance always reduces TU vibration risk.

Automation is transforming the assembly line, yet human expertise remains central. Practical assembler knowledge is increasingly embedded into software, statistical process controls, cameras, sensors and AI systems. “The key-knowledge is the teacher of such equipment and less the production operator on the line,” De Bruyne observes, underscoring a shift from manual skill to process intelligence.

Convincing OEM decision-makers to invest in this hidden discipline relies on data. Carmakers increasingly use market feedback tools, such as J.D. Power studies, tracking performance from delivery through the first year of ownership. This feedback drives Tier 1 suppliers to adjust processes in pursuit of customer satisfaction. Internal rejections between OEMs and wheel assemblers can also trigger upgrades, particularly when Tier 2 suppliers across global plants struggle with consistency. “Over the last 30 years, numerous additional optional processes have been introduced in the wheel assembly industry. While tyre shops may be aware of these processes, the high cost of the required equipment has often made it difficult to turn them into a viable business model,” De Bruyne concludes.

For an industry obsessed with powertrains, software and styling, tyre-wheel assembly may remain out of sight – but, as De Bruyne makes clear, it is increasingly central to how a vehicle feels, performs, and ultimately, how a brand is judged.

Apollo Tyres plans to invest INR 35 billion in FY2026-27, with nearly 80 percent of the capital expenditure earmarked for growth and capacity expansion projects across India and Europe, as the tyre maker seeks to meet strong demand despite escalating raw material costs and geopolitical disruption.

Most of the planned investment will be directed towards expanding truck and passenger car tyre capacity in India, while the remainder will support passenger car tyre expansion at the company’s Hungary plant.

Apollo Tyres said capacity utilisation across both India and Europe had reached about 90 percent, with demand remaining strong in replacement and original equipment markets. The company added that April volumes had continued to show strong momentum despite recent price increases.

The company reported consolidated revenue of INR 73.4 billion for the fourth quarter, up more than 14 percent year on year, while earnings before interest, tax, depreciation and amortisation margin improved to 14.6 percent from 13 per cent a year earlier.

Revenue from Indian operations rose 14.3 percent to INR 52.4 billion during the quarter, supported by high-teen volume growth in both replacement and original equipment segments.

Neeraj Kanwar, Vice-Chairman And Managing Director, said geopolitical developments in West Asia continued to create uncertainty and volatility across raw material, energy and logistics costs.

The company expects raw material costs to rise by mid- to high-teens sequentially during the current quarter, led by a sharp increase in natural rubber prices. Apollo Tyres said natural rubber prices had risen to about INR 250 per kg from around INR 200 per kg during the fourth quarter.

To mitigate the pressure, Apollo Tyres has announced price increases of 6-8 percent across product categories in India during the current quarter and indicated that further increases may be necessary.

Gaurav Kumar, Chief Financial Officer, said the inflationary environment remained highly volatile.

“Mid to high teens is the current reality,” Kumar said. “We’ve taken about half the price increase that is needed.”

The company said it was also implementing cost-control measures across operations, including reductions in discretionary spending, as it sought to protect margins from higher commodity and logistics costs.

Apollo Tyres continues to restructure its European manufacturing operations as part of efforts to improve profitability. The company said the closure of its Enschede plant in the Netherlands remained on schedule, with production expected to cease by June 30.

Management said the decision was driven by persistently weak European market conditions, elevated energy costs and unusually high wage inflation in western Europe.

Apollo Tyres has taken a non-cash write-off of EUR 43 million related to the plant closure and expects total restructuring-related cash outflow, including social plan payments and legal costs, to exceed EUR 55m.

The company said the restructuring should begin improving European margins during the second half of FY2026-27 as production shifts towards lower-cost facilities in Hungary and India.

Apollo Tyres added that India and Europe would remain priority markets for future capacity allocation decisions, although export demand in some overseas markets had softened amid broader macroeconomic uncertainty.
