New And Worn Phase Tests Make Tyres Safer And Long Lasting

Bahan 1

What does ‘Tyre Labelling’ guarantee? It shows schematically the classification of tyres in terms of fuel consumption, noise and wet performance. The tyre manufacturer is obliged to demonstrate the values ​​indicated on the label in tests carried out in accordance with the test method described in EU regulations. This essentially means that the performance parameters of the tyres in question are at least exactly at this level or above the positive side of the limit scale, but only when the tyres are new, i.e. at the beginning of tyre installation. It is technically expected that the stated performance values ​​will not change until the end of the first 10,000 kilometres or until wear of approximately 1.5 mm occurs.

Who knows what the actual grading of tyres will be after the second 10,000 kilometres or at 3 mm down wear stage? No one can correctly estimate what the wet noise and traction will be after most of the mini-kerf or notches are eliminated or reduced, but only when the tyre is tested it can be monitored. Or if the tyre's grooves are completely ‘V’ type, and after a period of time the tyre's traction forces change significantly, then rolling resistance and wet braking behaviour will become significantly different.

The performance level of worn tyres might be therefore quite uncertain and must be taken into account on a legal basis. The wet performance of worn tyres will be a check point for ‘wet grip class’ grading on EU Tyre label after 1st July of 2024, which is in line with the demand of tyre industry parties asking more sustainability.  Thanks to the introduction of a new EU regulation R117-04, tyres sold in EU distribution channels meet the same minimum wet braking performance requirements not only when new but also when worn down to the legal minimum tread depth of 1.6 mm.

EU is the most sensitive and advanced market to sustainability in the world. It is driven at any time by the increasingly aspiring regulatory agenda and there is always a constant development in this respect. Requirements of consumers or the automotive industry are more demanding by a more conscious society. Tyres’ life cycle contributing to a more sustainable future proactively identifies and addresses the potential human health and environmental impacts associated with the industry. Therefore, safer and more environmentally sound mobility options are always geared towards resource conservation and fuel economy amongst the focus points of innovations.


 

Thanks to the introduction of a new EU regulation R117-04, tyres sold in EU distribution channels meet the same minimum wet braking performance requirements not only when new but also when worn down to the legal minimum tread depth of 1.6 mm. They must therefore be tested both as new and as worn tyres before receiving the 'wet grade’ on the label. This means that EU drivers can now buy safer tyres that meet the legal minimum standards for wet braking performance, even when worn down to the legal minimum tread depth.

As a weak point of R117-04 regulation, it only covers wet braking of new and worn-out tyres. It does not cover ‘noise’ and ‘rolling resistance’ items given on labelling or more simply endurance performance level of especially cheap tyres in the market with a 1.6 mm tread depth assuming they will not change!

Informal wet braking tests conducted by ETRTO show that the wear rate of group ‘C1’ tyres can decrease by up to 50 percent, while the loss rate of group ‘C2’ and ‘C3’ tyres remain in 10 percent. The new regulation R117-04 therefore does not apply to group ‘C2’ and ‘C3’ tyres, as they normally have a greater tread depth and it is assumed that the level of wet braking does not change during the wear phase. However, since group ‘C1’ tyres have a smaller tread depth, it is assumed that their contact patch is more subject to negative changes, so that the wet braking performance also changes more after use. 

As a weak point of R117-04 regulation, it only covers wet braking of new and worn-out tyres. It does not cover ‘noise’ and ‘rolling resistance’ items given on labelling or more simply endurance performance level of especially cheap tyres in the market with a 1.6 mm tread depth assuming they will not change!

The new R117-04 regulation may mainly be considered as sustainability issue rather than total safety. It promotes tyre usage until defined min tread depth creating a room to consumers to trust the tyres above minimum tread depth level. However, it should still be positively considered a step forward to the worn tyres’ safety regulation. It accepts that wet braking level of worn tyres are more critical and important safety issue and should be regulated. By the way, consumers may use their tyres in longer stage, giving a contribution to a greener world.

The transparency provided by the new regulation, which came into force on 2024 July, is even more essential, as some performances deteriorate over time, especially in terms of safety. R117-04 in this term guarantees enhanced safety, better respect for the environment and the protection of motorists’ purchasing power. 

Common consumer behaviour shows that 50 percent of car tyres are demounted before reaching a residual depth of 3 mm and replaced with a new set of tyres.

Michelin has studied the safety margin of used tyres since 2018 and has stressed the importance of tyres to be used until 1.6 mm remaining tread depth. The best way was to test worn tyres because it can easily reflect the real risks a driver can face on the road. During the study, the results were surprisingly varied. It was shown that some worn tyres performed better than new tyres when braking on wet roads. This was exactly what Michelin has been saying for a long time. The performance of different tyre brands also varies considerably.

Common consumer behaviour shows that 50 percent of car tyres are demounted before reaching a residual depth of 3 mm and replaced with a new set. In global scale, this makes around 400 million tyres are prematurely scraped every year. A quarter of this amount, or almost 100 million tyres, would save at least 6 million tonnes of CO2 instead of reproducing it. The implementation of this regulation will certainly have an impact on the demand for new tyres in Europe.

R117-04 presently focus mainly on only tread depth attribute, while aspects such as ageing or rubber structural integrity degradation remain outside the scope of this amendment.

In addition, in the hope that higher performance requirements will not result in higher costs for consumers, the changes are designed to encourage consumers to continue using sustainable tyres instead. Once drivers are confident in their tyres, they will drive to a tread depth of 1.6 mm, potentially saving EUR 6 billion a year by not complying with proposals to reduce tread depth to less than 3 mm.

R117-04 presently focuses mainly on tread depth attribute, while aspects such as ageing or rubber structural integrity degradation remain outside the scope of this amendment. We also mentioned some additional weak points above. However, imposing these standards, will increase the driver’s awareness for worn tyres performance limits and let them to make more informed decisions when purchasing tyres.

On the other hand, understanding the ‘NEW AND WORN PHASE TESTS CONCEPT’ will become the standard mentality of the customer, who will be able to assess the attitude towards the initial performance of the tyres, which may change over time, but should not! The new challenge will be to weed out products that are not gripping in the wet when worn and have not met these expectations for years..!

Bridgestone Kheda Plant

The Indian automotive landscape is currently undergoing a seismic shift. Driven by the rapid rise of rural urbanisation, an aggressive government push for electrification and the development of world-class road infrastructure, the industry is witnessing a period of robust growth. With sales of both new and used vehicles touching record highs, the demand for high-quality tyres remains in a significant upswing.

At the helm of one of the market’s most prominent players is Rajarshi Moitra, Managing Director of Bridgestone India and Vice-Chairman, Automotive Tyre Manufacturers’ Association (ATMA).

In an interaction with Tyre Trends, Moitra discusses the company’s future-ready roadmap, from its substantial capacity expansions to a ‘sharp and deep’ strategic focus designed to maintain leadership in an increasingly premium and electrified market.

A BULLISH OUTLOOK ON THE SUBCONTINENT

While global economic indicators remain varied, Moitra is unequivocally optimistic about the local trajectory. “The Indian automotive industry is at an exceptionally positive juncture from a medium-to-long-term perspective,” he asserts.

This optimism is grounded in several structural tailwinds that suggest India is slated for very strong growth. Key among these factors is the sheer room for market expansion.

“Firstly, we are still significantly under-indexed in terms of car penetration, with only 50 cars per 1,000 people – well below even some smaller developing nations,” Moitra explains.

Furthermore, the geographical spread of wealth is changing. Bridgestone is observing massive growth in Tier 2, 3 and 4 towns, a phenomenon Moitra attributes to ‘rural urbanisation’.

Bridgestone India estimates a transformative half-decade ahead for the industry. “The number of affordable households – those capable of purchasing a car – will double in India over the next five year. When you couple this with the government’s massive capital outflow into road connectivity and the rise of e-commerce, it creates a very bullish environment for both passenger and commercial mobility,” Moitra says.

THE ‘SHARP AND DEEP’ STRATEGIC PILLAR

Despite India being the world’s largest two-wheeler market, Bridgestone is famously absent from that segment – and intends to stay that way for now. Moitra clarifies that the company’s philosophy is rooted in specialisation rather than horizontal expansion. “At Bridgestone, we believe in being ‘sharp and deep’ in our strategy,” he says.

Currently, Bridgestone India’s business split is heavily weighted towards the consumer segment, with 70 percent of sales coming from Passenger Car Radial (PCR), 25 percent from Truck and Bus Radial (TBR) and 5 percent from Off-the-Road (OTR) segment.

“We see enough headroom for growth within the passenger car segment across products, channels and customer experience, so we are focusing our resources on maintaining our leadership there,” Moitra notes, dismissing any near-term plans to enter the two-wheeler space.

Instead, the company is doubling down on ‘white spaces’ within the consumer car category, specifically targeting higher rim diameters and specialised compounds for Original Equipment Manufacturers (OEMs).

INVESTING IN CAPACITY AND LOCAL INTELLIGENCE

To support this growth, Bridgestone is moving aggressively on the manufacturing front. With current operations running at 90–95 percent capacity, the company is in the midst of a major investment cycle.

At present, the company’s Pune plant has a capacity to produce 4.01 million passenger car tyres and around 693,000 truck & bus radial tyres, while the Indore plant has a capacity to produce 7.11 million radial tyres for passenger cars and light trucks.

“Our last major investment was USD 85 million in October 2024, which is being ramped up in phases through 2029,” Moitra confirms. This capital is being used to scale volumes and enhance technical capabilities at the Indore factory.

The new investment is expected to further add 1.1 million tyre production capacity in Pune by CY2029, thus taking its total production capacity to around 11.1 million units in the country.

“Our strategy is two-fold: we want to be future-ready for market demand while simultaneously sweating our current assets to drive higher efficiency,” Moitra explains. Crucially, this expansion isn’t just about physical output; it’s about local autonomy. Moitra highlights that a ‘very large part’ of procurement is now local, decided by teams on the ground in India.

The launch of a Satellite Technology Centre in 2025 has further decentralised the company’s innovation engine. According to Moitra, this centre plays a pivotal role in increasing local leverage and technical presence, allowing the Indian arm to maintain a balance between local agility and global sourcing.

EVs AND PREMIUMISATION

As the Indian market matures, consumers are demanding larger wheel sizes – a trend Moitra says is led by OEMs. “We are seeing a clear market shift towards higher inches – for example, a car like the Maruti Suzuki Swift moving from 14-inch to 15-inch and others moving from 16-inch to 17-inch,” he observes.

Bridgestone’s ‘all-inch’ strategy covers the spectrum from 12 to 20 inches, but their brand strength is most potent in these premium, higher-diameter sizes.

This premiumisation dovetails with the transition to electric vehicles (EVs). Bridgestone has positioned itself with an ‘EV-ready’ portfolio, exemplified by the Turanza 6i. “It balances long-lasting durability and safety with low noise and comfort – essential for EVs,” says Moitra. To ensure they capture this nascent but fast-growing market, the company expanded the range from 36 sizes in 2024 to 72 sizes by 2025.

The OEM relationship remains the cornerstone of this technological foresight. “The OEM segment allows us to see ahead of the curve regarding future vehicle technologies,” Moitra explains.

At present, 35 percent of their consumer business is OE-based and Bridgestone is in active discussions with many of the newer automotive entrants arriving in India.

While Bridgestone is aggressively expanding its footprint in new tyre technology and premium consumer segments, it is taking a markedly more conservative approach towards the retreading sector in India. Despite the potential for material circularity, the company does not view retreading as a strategic priority for the immediate future.

Moitra clarifies that Bandag, Bridgestone’s global retreading arm, is not currently active in India, and there are no plans to introduce it in the near-term. This decision is driven largely by the unique and challenging dynamics of the local market, which is currently dominated by cold retreading.

He points out that a significant pricing challenge exists when ‘cold retreads versus biased tyres versus some of the cheaper tyres’ are compared, making the business case difficult to justify at this stage. Consequently, Bridgestone has opted to remain focused on its core segments for the next two to three years rather than entering the retreading space.

SUSTAINABILITY AND THE ‘INSTITUTION OF RESPECT’

Beyond the numbers, Bridgestone is attempting to build what Moitra calls an ‘institution of respect’. This involves a heavy commitment to environmental goals. The Pune plant already holds the distinction of being the first carbon-neutral facility in the Bridgestone group.

“Sustainability is a core agenda across our entire value chain,” Moitra explains, noting a public commitment to reduce the company’s carbon footprint by 50 percent by 2030, including Scope 3 emissions. This holistic approach ranges from manufacturing processes to material circularity in the tyres themselves.

Looking ahead, the goal is to protect a dominant market share – currently over 20 percent by volume and 23 percent by value in the passenger car aftermarket. To do this, Bridgestone plans to expand its physical reach by 30 percent over the next five years, building upon its current network of over 4,000 touchpoints.

As the company transitions its branding from the Olympics to Formula E, the focus remains clear: high performance and the next era of mobility. “It’s the perfect platform to showcase our technological edge,” Moitra concludes.
