Pirelli and the Motorcycle World Championship paddock visit the Motegi Mobility Resort, formerly known as Twin Ring Motegi, for the Japanese Grand Prix (4-6 October) in a rare novel challenge for the tyre supplier. While Pirelli has competed on some races in the domestic All Japan Road Race Championship, it has never raced with either the Moto2 and Moto3 classes or other major international competitions at the circuit, meaning it has little data to rely on. As a result, Pirelli has opted for the standard tyres from the Diablo Superbike range included in this year’s standard allocation, albeit in greater quantities for some compounds.
The Yokohama Rubber Co. Ltd. has joined the “Fry to Fly Project,” which pursues decarbonization of the airline industry by recycling domestic resources. Led by JGC Holdings Corporation, the project involves collecting waste cooking oil generated by companies and households and using it for the production of sustainable aviation fuel (SAF) to power aeroplanes. As of 31 July 2024, 143 companies, municipalities, and organizations were involved in the project.
As part of a project involving parties based in Japan and Indonesia, Bridgestone Corporation is working to develop technologies for preventing White Root Disease (WRD) in Para rubber trees. WRD kills rubber trees by infecting the roots with pathogenic fungi that causes tissue decay, and the disease’s onset is difficult to detect. By developing technologies to prevent fungal infection, the project aims to stabilise the yield of natural rubber and improve the productivity of plantations.
Yokohama Rubber has commercially introduced a new technology it has been working on for a number of years, aerodynamic fins that improve handling stability. It debuted this feature on the Yokohama Advan A50, a size 165/50R16 75V tyre currently only available in Japan as an original equipment fitment on the Daihatsu Copen two-door convertible kei car.
The Mitsubishi Chemical Group (MCG) is studying the “chemical recycling of end-of-life tyres (ELTs) by utilizing the coke ovens at its Kagawa Plant in Sakaide City, Kagawa Prefecture, Japan. The MCG Group aims to begin marketing sustainable carbon black made from ELTs by March 2026.
From July, Yokohama Rubber is supporting its tyre development programme with a system that uses eXplainable AI (XAI) to make the development process clearer and more efficient. This advanced system aims to improve the work of both seasoned and less experienced tyre developers, reducing lead times and cutting costs.
Japan Airlines Co., Ltd. (JAL) and Bridgestone Corporation have extended the application of their tyre wear prediction technology to implement scheduled tyre replacement operations for large jet aircraft, including the Airbus A350-900, which JAL has operated since May 2024.
Sumitomo Rubber Industries, Ltd. is partnering with leading experts in Japan on a significant project unrelated to tyres but with substantial societal benefits. Together, they are working on developing a new cancer therapy using a “cancer cell absorption kit” that employs a unique polymer developed by Sumitomo Rubber.
In its fifth annual survey the Japanese technology company Asahi Kasei asked car users in four major automotive markets (Germany, the United States, China, and Japan) about brand loyalty and key motivators for buying electric vehicles (EVs). The results suggest tightening competition, new manufacturers entering the markets, and – perhaps as a result – “brand loyalty is wavering worldwide”.
In collaboration with several partners, Sumitomo Rubber Industries, Ltd. has achieved a further breakthrough in tyre technology. SRI teamed up with experts from institutes within Japan to develop a new synchrotron radiation technique that can measure the motion of atoms, molecules, and nanostructures within an extremely short timeframe, including down to 1 nanosecond. With this advancement, the Falken brand manufacturer anticipates enhancing its tyres’ strength and wear resistance.
Sumitomo Rubber Industries (SRI) reports a 5.3 per cent year-on-year increase in sales revenue during the quarter ending 31 March 2024, to ¥291,360 million (£1,482.03 million). Business profit surged by 190.7 per cent to ¥23,183 million (£118.04 million), operating profit rose by 166.5 per cent to ¥20,696 million (£105.31 million) and profit attributable to owners of the parent jumping by 520.2 per cent to ¥24,841 million (£126.47 million).
Sumitomo Rubber Industries, Ltd. (SRI) has unveiled a new technique for predicting noise generated by the combined vibration of tyres and vehicle. By simulating how tyres roll when in motion and applying the lessons learned, SRI anticipates that both tyre and vehicle manufacturers will be able to reduce their products’ noise emissions.
The Yokohama Rubber Co., Ltd., has announced its participation in a venture spearheaded by the Japan Ministry of the Environment. This initiative, a component of the Japanese Government Cabinet Office’s BRIDGE programmes, aims at assessing and affirming the sustainable acquisition of natural capital from the ASEAN region.
The Yokohama Rubber Co., Ltd. plans to expand production capacity for motorsport tyres at its Mishima facility in Japan’s Shizuoka Prefecture. Yokohama Rubber will invest about ¥3.8 billion (£19.4 million) in a new line that will produce 18-inch and larger motorsports tyres, expanding the plant’s capacity for motorsports tyres by 35 per cent.
