A colossal fire engulfed a significant portion of Kumho Tire's Gwangju manufacturing plant on 17 May 2025, forcing a complete halt in production and prompting authorities to issue a nationwide firefighting mobilisation order reported Korea Times. The company is South Korea’s second-largest tyre manufacturer.

The blaze, which began around 7:11 am local time, rapidly consumed factory buildings, with flames reportedly reaching heights of up to 100 metres.

The report further stated that by 5 pm on Saturday, approximately 70 percent of the plant's western section – an area roughly equivalent to five football fields – had been devastated by the fire. Firefighters concentrated their efforts on preventing the flames from spreading to the southern section of the facility, which is separated from the severely impacted western area. The National Fire Agency's had to deploy crucial personnel and equipment from neighbouring regions to help control the disaster.

What’s important to know is that about 400 on-duty workers were safely evacuated. However, one male employee in his 20s sustained non-life-threatening injuries and was transported to a local hospital. Additionally, two firefighters were injured during the ongoing efforts to control the blaze.

The local authorities suspect the fire originated from equipment used for heating raw rubber. Then there was the challenge about the estimated 20 tonnes of raw rubber stored at the factory, which is significantly hindering firefighting efforts.

This incident will not only have financial impact for Kumho Tire but also supply constraint for its major customers such as Hyundai Motor Corporation and Kia Corporation.

Last year, Kumho Tire reported sales of USD 3.21 billion and an operating profit of USD 431 million.

"With the fire now under control, we will soon be able to announce our estimated losses and outline plans for relocating our production lines," the report quoted a company official.

Hankook Tire is set to showcase its advanced commercial tyre portfolio at the inaugural Road Transport Expo (RTX) Ireland, scheduled for 15 and 16 April 2026 at the Eikon Exhibition Centre in Lisburn. Hankook will display the pioneering e-SMART City AU56 EV bus tyre, the new Smart Work AM11+ for regional distribution, the versatile SmartFlex range for long-haul applications and value-focused Laufenn commercial tyres. Organised by the team behind the successful RTX Stoneleigh and RTX Scotland events, RTX Ireland 2026 brings a dedicated truck focus to Northern Ireland. With over 50 exhibitors and an expected attendance of more than 7,000 visitors, the event serves as a crucial hub for the Irish road transport sector to network and discover industry-shaping innovations. Attendees can find Hankook alongside its exclusive distributor, TyreCall and Tractamotors, at Stand C15.

Among the featured innovations is Hankook’s pioneering e-SMART City AU56, the brand’s first electric bus tyre introduced in 2024. Engineered for the unique demands of electric urban transport, this tyre offers low rolling resistance for extended range, reduced noise for enhanced passenger comfort and robust durability to manage the high torque and heavier loads of electric vehicles. Also on show will be the recently launched Smart Work AM11+, a tyre specifically developed for the rigours of regional and local distribution. Its design provides strong resilience against the wear and tear of stop-start operations, making it ideal for demanding sectors like waste management, with reinforced sidewalls for extra protection.

For fleets covering regional and long-haul routes, Hankook will present its SmartFlex range. The SmartFlex AL51 for steer axles and DL51 for drive axles are engineered for consistent performance throughout their lifespan. Reflecting Hankook’s commitment to sustainability and cost-efficiency, these tyres are both regroovable and retreadable. Complementing the Hankook portfolio, visitors can also explore the Laufenn brand, including the Laufenn365 initiative. The Laufenn commercial range, featuring the LF95+ trailer tyre, LF22 all-position tyre and LZ22 drive tyre, leverages Hankook’s advanced technology to deliver strong value, full retreadability and a reduced environmental footprint, catering to budget-conscious operators. This participation underscores Hankook’s growing leadership in the UK truck tyre replacement market, driven by continuous innovation and tailored solutions for an evolving industry.

The Tire Industry Project (TIP) has released the updated Product Category Rules (PCR) for tyres in collaboration with UL Environment. This revision establishes a more robust framework for measuring environmental performance and promotes consistent transparency throughout the tyre sector.

A Product Category Rule serves as a standardised guide for manufacturers to conduct lifecycle assessments and create Environmental Product Declarations that enable meaningful comparisons between similar products. Valid for the next five years, the revised PCR integrates current scientific findings, including enhanced methods for tracking greenhouse gas emissions. It reflects modern production realities such as the adoption of renewable energy in manufacturing plants and incorporates evolving vehicle technologies like improved fuel economy and alternative fuel sources. The update also mandates uniform reporting when new materials are introduced, simplifying the monitoring of sustainability advancements.

Independently adopted by the 10 member companies of the Tire Industry Project, which collectively account for 60 percent of global tyre production capacity, this fourth edition encourages wider voluntary implementation across the industry. Developed through collaboration among major manufacturers, the PCR standardises how environmental footprints are calculated from raw material extraction through disposal, ensuring comparability of Environmental Product Declarations. This comparability supports environmentally conscious purchasing decisions and fosters ongoing improvements in sustainability across the value chain.

Key enhancements include refined carbon footprint calculations addressing biogenic carbon, expanded applicability to all tyre categories including off-road and specialty tyres and greater regional accuracy by incorporating localised data on end-of-life tyre management, vehicle efficiency, energy mixes and payload considerations. The methodology now provides a clear hierarchy for assessing impacts in multi-product manufacturing environments, aligns impact indicators with the European Commission’s Environmental Footprint 3.1 framework and updates raw material datasets and emission factors for improved data quality.

UL Solutions, an independent safety science organization, collaborated closely on developing and publishing this updated PCR.

Dr Larisa Kryachkova, Executive Director, TIP, said, “The updated PCR reflects years of collaboration and investment to advance sustainability across the tyre value chain. Our goal is to strengthen environmental reporting. With a common methodology, we support better industry-wide decision-making, turning ambition into positive environmental action.”

Ranee Valles, Director and General Manager – Product Sustainability, UL Solutions, said, “Transparent, standardised reporting enables manufacturers, regulators, fleet operators and consumers to make informed choices about the products they use or supply. Our collaboration with TIP reflects a shared commitment to credible, science-driven solutions, and we’re grateful for TIP’s leadership in advancing scientific rigour and industry alignment on environmental reporting.”
