Tyre retreading

A population of over 1.4 billion people catapulting into the world’s third largest automobile market with four million trucks plying across a road network of 6.3 million kilometres supported by a USD 13.4 billion tyre market and a mining sector contributing around 2–2.5 percent of the country’s GDP demonstrate the strength of India’s automobile, freight and tyre sectors.

The story doesn’t end there as the Central Government adopts a strategic approach on reducing carbon emissions across these verticals, especially automobile and tyres, with targets such as the Net Zero Carbon Emissions by 2070, battery electric vehicles target by 2030, zero-emission truck corridors, Extended Producer Responsibility for the tyre sector; the list just goes on.

Amidst all such statistics and targets, a silent spectator remains the old and varied sector of tyre retreading. In a recent news story reported by Tyre Trends, the Indian Tyre Technical Advisory Committee (ITTAC) had made a proposal to Tyre Retreading Education Association (TREA) for mandating certain standards that will improve the quality of retreads.  ITTAC has made recommendations to the BIS committee. TREA is part of the same committee. ITTAC and TREA are recommending different standards.

These standards included BIS retread standards, namely IS 15725, IS 15753, IS 15524 and IS 9168. The ITTAC had partially aligned Indian requirements with ECE R109, the European regulatory benchmark.

In a reply to the proposal, which was accessed by Tyre Trends, TREA urged the Indian Tyre Technical Advisory Committee to seek a deferment or non-applicability of BIS standard IS 15704:2018 for retreaded commercial vehicle tyres, warning that mandatory enforcement could cripple the sector.

In the letter, TREA argued that IS 15704:2018 is largely modelled on new tyre manufacturing norms and is technically unsuitable for retreading, which is a restoration and recycling process.

The standard mandates advanced laboratory tests such as spectrometer-based rubber analysis, endurance testing and compound uniformity checks, requirements that most retreading units, particularly small and medium enterprises, are not equipped to meet

The association highlighted that even large retreaders lack the infrastructure and skilled manpower needed for BIS-grade testing, while the sheer number of retreading units would make inspections and certifications operationally unmanageable for regulators.

TREA warned that compliance costs linked to machinery upgrades, audits and quality control could force 70–80 percent of units to shut down, leading to job losses, higher fleet operating costs and adverse environmental outcomes due to reduced recycling

Instead, TREA proposed that BIS prioritise retreading-specific standards such as IS 13531 and IS 15524, which focus on materials, process control, safety and quality consistency.

The body has also called for a phased transition roadmap, MSME support and industry training before any stricter norms are enforced, stressing that abrupt implementation would undermine the sector’s role in India’s circular economy.

The conundrum

India has a total of 36 administrative divisions comprising 28 states and 8 union territories. The tyre retreading sector has been continuously supporting circularity goals since the early 1970s across the world’s largest economy without getting mainstream recognition.

Even after five decades in service, the industry battles different bottlenecks including fragmentation, manpower shortage, tax pressures brought about by the recent GST revisions and now the implementation of such standards, just to name a few.

The sole practice that can simultaneously reduce carbon emissions from tyres and extend tyre life is assumed the nemesis of an ‘infamous and dangerous practice’ in some states of the country.

However, the industry has been drawing its techniques and quality parameters from the world’s oldest retreading economy, Europe.

“Big retreaders in India already have the necessary processes in place that conform to IS 15524 standards. However, as the standard is not yet mandated, we have voiced support for it because it is process-oriented and outlines how retreading should be carried out, including buffing and building procedures,” said TREA Chairman Karun Sanghi.

He added, “This standard focuses on how the work is done rather than imposing product-level testing that cannot be practically implemented. The current debate on IS 15704 stems from it being fundamentally incompatible. The standard includes requirements such as sidewall marking and destructive testing of retreaded tyres, which are impractical in a retreading environment where each tyre differs in brand, size, application and usage history,” he added.

Destructive testing, he argued, assumes uniform batch sizes. In retreading, where every casing is unique, testing even a single tyre would mean destroying finished products without yielding representative results. Applying such a framework would effectively require the destruction of every tyre in a batch, making compliance unviable.

“We have submitted our response to ITTAC and are awaiting feedback from the committee. We remain open to continued dialogue and will engage further once the committee responds to our submission,” said Sanghi.

According to him, a typical retreader processes about 300 tyres a month across multiple brands including MRF, JK Tyre, Apollo and Michelin and applications ranging from buses and trucks to mining vehicles. These casings vary widely in load cycles, operating conditions and duty patterns, often across several models from the same manufacturer.

The committee has cited European standard ECE R109, but Sanghi points to structural differences: “Europe is a global retreading hub where tyre manufacturers such as Michelin and Bridgestone dominate operations, collect their own tyres, retread them and return them to fleets, making batch-based destructive testing relevant. A similar model exists in US, where large tyre companies lead retreading and largely self-regulate without a single overarching standard. The Indian scenario is different, especially with a fragmented market.”

He stressed that the industry is not opposed to standards but to those that cannot be practically applied, warning that adopting European manufacturing-oriented norms without accounting for India’s market structure and operating realities would be counter-productive.

The debate is no longer about whether standards are needed but whether they are fit for purpose. Without accounting for India’s fragmented retreading ecosystem, enforcing impractical norms could dismantle a circular industry in the name of compliance.

Sun Auto has expanded its strategic footprint by acquiring two locations: Highland Auto in Tennessee and Highland Tire at Sentry Station in Georgia. This marks the company’s first entry into Georgia and adds a fourth Tennessee site, enhancing regional network connectivity.

The move supports Sun Auto’s broader 2026 growth campaign, which includes new operations in Colorado and brings the company’s total presence to 27 states nationwide. Both acquired shops join the Sun Auto Network, gaining access to 24/7 online scheduling, digital vehicle inspections and the company’s Driver Commitment focused on clarity, confidence and customer care.

Each location provides a full range of automotive services, including major tyre brands with a price match guarantee, alignments, brake service, oil changes, batteries, diagnostics and preventative maintenance. Sun Auto now operates over 575 locations nationwide through both acquisitions and new builds.

Chris Tavares, SVP Operations, Sun Auto, said, "Expanding into the Southeast is an important step in strengthening our national footprint and positioning our network for long-term growth. Establishing a presence in Georgia allows us to serve more customers, support our teams with greater regional resources and build stronger continuity across key markets."

Hankook Tire has formally launched a major national research initiative at its advanced Hankook Technodome facility in Daejeon. The kick-off gathering took place on 4 June to begin work on a project titled ‘Development of Tire Manufacturing Technologies Using Sustainable Materials’, which falls under the Ministry of Climate, Energy and Environment’s 2026 Environmental Technology Development Program.

The core objective of this undertaking is to accelerate South Korea’s transition to a circular economy by deriving high-grade recycled inputs from discarded tyres. Two parallel tracks of research involve creating premium reclaimed materials from waste rubber and establishing manufacturing processes that rely on sustainable components. Hankook Tire has been a driving force in this field since 2023, leading the domestic Tire-to-Tire consortium, and has already brought to market the iON GT, an electric vehicle tyre composed of over 70 percent sustainable content.

Participation in this government-backed programme allows Hankook to broaden its existing private sector work into a larger cooperative framework that includes universities, research bodies and industry partners. The company intends to strengthen its ability to adapt to evolving environmental rules while making its raw material supply chains more resilient. The project consortium brings together 11 entities, with M&B Green Earth acting as the lead institution alongside Kumho Petrochemical, HS Hyosung, Solvay, KRICT, KAIST and several other academic and technical organisations.

Hankook Tire ultimately targets the commercial release of next-generation, low-carbon tyres containing more than 85 percent sustainable materials and capable of cutting carbon emissions by over half. The project will also allow for large-scale validation of the domestic Tire-to-Tire circular model through product demonstrations and integrated performance assessments. Further demonstrating its commitment, the company recently attended the April launch of the Eco-design Forum, where industry players discussed compliance with the EU Ecodesign for Sustainable Products Regulation.

Bonhee Koo, Head of the R&D Innovation Division at Hankook Tire, said, “This national R&D project presents a meaningful opportunity to bring together the expertise of leading industry, academic and research institutions. Through close communication and collaboration among all participating organisations, we will strive to deliver tangible outcomes that contribute to strengthening competitiveness in the global market.”

American tyre brand General Tire has officially widened its all-terrain product family by unveiling the Grabber AT3 Plus, a new all-season tyre engineered for unpredictable weather and rugged off-road use. The launch addresses the rising popularity of both traditional 4x4 vehicles and the rapidly expanding sport utility vehicle segment, offering a single solution that balances highway driving with trail capability.

When measured against the previous model, the latest Grabber delivers superior snow traction and enhanced wet-road grip thanks to a thoroughly reengineered tread design that visually signals its off-road intentions. Durability remains a priority, as both the compound and tread pattern have been optimised for harsh conditions while still providing precise handling and reduced cabin noise. The tyre is built for year-round use on pavement and dirt, and every available dimension bears the three-peak mountain snowflake symbol, ensuring legal compliance for winter driving across numerous countries.

Upon its release, the Grabber AT3 Plus will be offered in rim diameters ranging from 15 to 22 inches, widths between 195 and 315 millimetres and aspect ratios of 80 down to 40 percent. Certain sizes carry LT identification along with LRD and LRE load ratings, making them suitable for heavy-duty applications, while speed ratings can reach up to 240 kilometres per hour. To achieve its balance of toughness, grip and ride quality, General Tire integrates three proprietary systems: TracGen for loose-surface traction and on-road precision, Comfort Balance for smooth rolling and noise reduction and DuraGen for cut-resistant tread blocks and stone bumpers.

A rugged sidewall with a pronounced shoulder, clear tread markings and logo detailing gives the tyre an assertive appearance that complements modern SUVs and off-road vehicles. Depending on the dimension, the Grabber AT3 Plus earns a C grade for wet braking, a B for noise emissions and most commonly a D for rolling resistance.

Matthias Bartz, Business Development Manager – EMEA, General Tire, said, “Our R&D department has achieved a remarkable feat in further developing the leading Grabber AT3. The Grabber AT3 Plus delivers improvements across all key performance areas – without any compromises.”

Michelin North America, Inc. is participating once again in a special journey to transport World War II veterans to Normandy, France, in observance of the 82nd anniversary of D-Day. The initiative is carried out in collaboration with the Best Defense Foundation and Delta Air Lines, reflecting a unified effort to preserve the memory of veteran courage and sacrifice through direct, intergenerational experiences rather than solely through historical texts.

A charter flight carrying the veterans departed on 2 June, accompanied by caregivers and volunteers from the partner organisations. Over the course of a nine-day stay, the group will attend commemorative ceremonies and celebrations marking the anniversary. The Best Defense Foundation views the journey as not merely a commemoration but a meaningful opportunity for connection.

This year’s programme again includes students selected through the Best Defense Foundation’s NextGen initiative, who travel alongside the veterans as escorts and witnesses. From Omaha Beach to Pegasus Bridge and Carentan, the students will explore historic sites with those who lived through the events, ensuring that the stories of service members are passed on with authenticity and respect.

The collaboration among Michelin, the Best Defense Foundation and Delta Air Lines began in 2021 and has brought veterans back to France each year since the 78th anniversary in 2022. Michelin’s historic link to D-Day dates to spring 1944, when the 1939 Michelin Guide’s detailed maps were reprinted by Allied commanders to aid navigation in France. The company later produced additional maps for Allied advances, earning formal recognition from Allied Forces, and continues that legacy today through acts of remembrance and return.

Matthew Cabe, President and CEO, Michelin North America, Inc., said, “It is deeply meaningful and humbling for Michelin to stand alongside these veterans in Normandy. Supporting this initiative is one way we demonstrate our deep gratitude for these heroes and ensure the significance of their service is carried forward for generations to come.”

Bob Somers, Senior Vice President – Global Sales, Delta, said, “As we mark the fifth year of the Normandy Legacy Flight, we are reminded that carrying forward a legacy of this magnitude requires partners who share not only our values but a deep sense of purpose and responsibility. We are profoundly grateful for our partnership with Michelin, whose steadfast commitment and collaboration make this mission possible year after year. Together, we are honoured to pay tribute to our nation’s greatest heroes by preserving their legacy, honouring their sacrifice and ensuring their stories endure for generations to come.”

Donnie Edwards, Founder, Best Defense Foundation, said, “Michelin's commitment to this mission goes beyond sponsorship. It is a shared belief that the men and women who fought for our freedom deserve to be remembered, honoured and heard. Because of partners like Michelin, we are able to bring veterans back to the places that shaped history and ensure their stories live on in the people who will carry them forward.”
