Tyre retreading in process

The Indian Tyre Technical Advisory Committee (ITTAC) has made a proposal to Tyre Retreaders Education Association (TREA) for mandating certain standards that will improve the quality of retreads.

Speaking to Tyre Trends about the move, a source privy to the developments explained, “We have sought TREA’s views on mandating the retread standards and we are currently awaiting their formal response on the subject. Once an agreement is reached with TREA, a formal proposal will be submitted to BIS for consideration. At present, the retread sector is largely unorganised with more than 10,000 retreaders operating. Once the applicable standards are mandated, all retreaders will be required to comply with the relevant BIS standards and mark their products with the BIS certification marks.”

“Considering the large number of retreaders operating in the market, enforcing retread standards will be a significant challenge for BIS,” he added.

As per an ICRA report, the Indian retreaded market was valued between INR 580 billion and INR 600 billion with a cumulative annual growth rate of 7–9 percent between FY23-26. As the market continues its projected trajectory, quality and efficacy become paramount not only to bolster recognition and usage but also to make a name at the global level.

The documents that were accessed by Tyre Trends signal a major restructuring of test procedures and physical property norms across key retreading standards.

At the centre of the exercise is remarks from Central Institute of Road Transport (CIRT), supplemented by inputs from a major tread maker, covering four foundational BIS retread standards, namely IS 15725, IS 15753, IS 15524 and IS 9168.

TREA members are yet to assess proposed updates to the physical-property criteria for uncured rubber including tread, belt, undertread, base and cushion gum compounds.

The technical work on retread-casing standard IS 15704 represents the most sensitive part of the proposal. Furthermore, ITTAC has partially aligned Indian requirements with ECE R109, the European regulatory benchmark.

Key alignments include widening allowable outer-diameter growth for tyres with section widths above 305 millimetre, raising permissible deviation from two percent to 3.5 percent for high-aspect-ratio radial tyres and four percent for bias-ply constructions.

ITTAC also endorsed the addition of a one percent deviation allowance for snow tyres, consistent with R109 clause 7.1.5.2.

The recommendations in the proposal also contains inputs from Michelin Tyres. The company had proposed a full R109-based clause on minimum material thickness above the breaker for diagonal-ply casings.

ITTAC did not accept the full wording, arguing that IS 15704 already covers requirements for both radial and bias tyres, but acknowledged that the minimum 0.80 millimetre non-repair spot thickness must be explicitly stated to prevent accidental exposure of the belt package during buffing operations, informed the source.

Alluding to how these changes will be incorporated, he noted, “As far as process is concerned, like in case of new tyres, retreader will apply to BIS for getting the license. After reviewing the application, a BIS auditor will visit the retreading facility and collect samples for testing at BIS-authorised laboratories. The laboratories will conduct tests as specified in the standard and submit their reports to BIS. If the sample successfully meets all requirements, a license is issued to the retreader, allowing them to mark their retreaded tyres with the applicable ISI mark.”

India’s retreading sector now stands at a defining crossroads. The push by ITTAC to formalise and mandate BIS standards marks a decisive shift from a largely fragmented landscape to one governed by measurable, certifiable quality benchmarks.

For more than 10,000 retreaders, the transition will not be easy as compliance, auditing and testing will demand new investments, capabilities and mindsets.

Yet, this transformation also presents an unprecedented opportunity. Standardisation could elevate Indian retreads from a cost-driven alternative to a globally credible, technically assured product category.

As TREA prepares its response and BIS gears up for the next drafting phase, the onus now lies on industry players to embrace this moment. If executed well, the reforms could not only improve safety and performance but also position India as a competitive force in the international retreading arena.

Apollo Tyres Ltd is broadening its cycling portfolio with a new all-season, high-performance option: the Vredestein Superpasso Pro 4S. Engineered for competitive cyclists, this tyre is designed to provide reliable speed and handling throughout the year, regardless of weather or road conditions. It will be available across Europe from 1 March 2026 in four different width sizes to accommodate various road bikes.

Developed at the company's European Global R&D Centre, the tyre builds upon the existing Superpasso Pro platform. It aims to merge the low rolling resistance and responsiveness of a summer performance tyre with the enhanced grip, durability and puncture resistance necessary for consistent year-round use. A key innovation is the proprietary ‘TriComp’ technology, which utilises multiple rubber compounds. A harder, reinforced centre section promotes efficiency and longevity, while softer shoulder compounds deliver superior traction and stability when cornering, even on wet or uneven surfaces.

Further contributing to its all-season capability is an optimised tread pattern. This design efficiently channels water away and maximizses the tyre's contact patch with the road, ensuring predictable handling. Underneath this tread, a 120 TPI casing and a reinforced breaker layer work in tandem to bolster puncture protection and overall resilience. Additionally, the model incorporates ‘Active Control Technology’, featuring a unique bridged centre structure. This construction method reduces overall weight and enhances the direct feedback transmitted to the rider, resulting in a more agile and connected riding experience.

Nic Knippers, Divisional Head – Vredestein Two Wheel Tyres, Apollo Tyres Ltd, said, “Following the success of the new-generation Superpasso Pro, we saw a clear opportunity to create an all-season variant that would allow competitive and enthusiast riders stay on the bike longer, regardless of the weather. The Superpasso Pro 4S achieves exactly that, faithfully transmitting rider power and steering inputs to all surfaces, year-round.”

For over a decade, Continental has served as the exclusive tyre supplier to Cemex in the UK, providing comprehensive solutions for the building materials leader's entire fleet. This partnership, initiated in 2011, began when Cemex selected retreaded tyres from Continental’s Bandvulc brand and became an early adopter of the ContiConnect digital monitoring system. Cemex, founded in 1906 and a major supplier of concrete, asphalt and aggregates, operates an extensive UK network of quarries and plants serviced by a large fleet of cement vehicles, dump trucks, trailers and ships.

The demanding environments at Cemex sites, featuring sharp rocks and uneven terrain, previously made tyre-related vehicle breakdowns a significant operational hurdle. By equipping the fleet with Continental’s premium new and retreaded tyres, the company has substantially enhanced vehicle safety, reduced downtime and improved overall fleet efficiency. According to Carl Milton, Cement Logistics Manager – UK at Cemex, this open-book relationship has yielded continuous benefits, from lowering driving costs to increasing vehicle durability and performance.

A cornerstone of this collaboration is the ContiConnect tyre pressure monitoring system. Sensors in the tyres provide real-time data on inflation and temperature, transmitting this information to cab displays and a web-based platform for fleet management. Nigel Ponton, UK Fleet Engineering Manager at Cemex, notes that the system does more than monitor deflation; it analyses heat transfer to predict imminent brake or wheel bearing failures, enabling proactive maintenance. Email alerts from the platform allow both the transport team and tyre providers to address issues in advance, supported by additional checks from Yard Reader stations at Cemex plants.

The partnership has deepened through joint innovation and testing. Milton highlights that the two companies have worked closely to optimise tyre designs for Cemex’s unique operational environments, achieving the best possible fuel economy. Cemex is frequently invited to trial new tyre models, providing feedback that directly contributes to the refinement and development of Continental’s product range. Pina Wallace of Continental concludes that this cooperative relationship is a perfect example of mutual success, where tailored solutions meet specific customer demands while invaluable feedback enhances product offerings. This synergy underscores Continental’s customer-centric approach and the tangible, shared value born from a deeply collaborative alliance.
