Bridgestone has introduced a new addition to its Potenza ultra-high-performance line: the RE-71RZ extreme summer tyre. Designed specifically for grassroots racing, this tyre succeeds the acclaimed RE-71RS model. It aims to deliver quicker lap times and sharp, responsive handling, empowering drivers to maximise their performance on the circuit. A cornerstone of its design is the incorporation of ENLITEN technology, Bridgestone's next-generation platform focused on enhancing durability and advancing sustainable product design.

The tyre's development directly targets key performance metrics. On-track testing at Japan's Tsukuba Circuit demonstrated significant improvements, with the RE-71RZ achieving lap times approximately three-quarters of a second faster than its predecessor in both dry and wet conditions. This gain is attributed to several advanced engineering features. A new high-grip rubber compound, developed using insights from motorsports and proprietary NanoPro-Tech, enhances traction at a molecular level. The tread pattern has been redesigned with a stiffer construction and a larger outside shoulder to improve grip and stability, while a strategically placed main groove on the inside edge helps suppress uneven wear for longer track life. Furthermore, Bridgestone utilised its unique ULTIMAT EYE digital modelling tool to optimise the tyre's structure, creating a more uniform contact area for superior cornering grip.

Professional drivers Masahiro Sasaki and Yuji Tachikawa provided critical feedback during development, their expertise helping to refine the tyre's track-focused characteristics. The Potenza RE-71RZ builds upon a legacy that began in 1979, crafted for enthusiasts who demand competition-ready performance that transitions from daily driving to weekend motorsports. It has been approved for competition use by the Sports Car Club of America (SCCA) and will be eligible for Solo and Time Trials events starting in 2026. The tyre will be offered in 45 sizes and is scheduled to launch in the North American market on 31 December 2025.

Sasaki said, “As its strong point, the Potenza RE-71RZ achieves a high level of performance in both grip and controllability. It delivers improved dry and wet performance for street use while also achieving faster lap times and better wear resistance on the track. This tyre delivers high performance in various situations, making it enjoyable and easy to handle for both everyday driving and track use.”

Tachikawa said, “This tyre is designed for easy handling, allowing anyone to experience precise control along with excellent grip. The tyre is focused on quick warm-up for immediate, high-grip performance as well as reliable wet grip, resulting in a well-balanced tyre suitable for various driving conditions.”

The Association of Natural Rubber Producing Countries (ANRPC) recently hosted a high-level delegation from the Rubber Development Division of the Ministry of Plantation and Commodities Malaysia at the ANRPC Secretariat. Led by Peter Dennis of Malaysia’s Rubber Development Division, the group met with ANRPC Secretary-General Dr Suttipong Angthong and his team.

The discussions centred on essential industry issues, particularly the vital importance of achieving stable rubber prices for the benefit of producers and the broader market. Conversations further delved into analysing recent market trends and their consequences for global production and trade dynamics.

This engagement highlighted the ongoing necessity for cooperative action to address sectoral challenges, advance sustainability and ensure resilient growth in the face of variable economic conditions.

Bridgestone Americas has unveiled its latest flagship winter tyre, the Blizzak IcePeak, which will launch nationwide in May 2026. This new tyre is distinguished as the first from Bridgestone to achieve both the rigorous 3-Peak Mountain Snowflake and Ice Grip certifications, marking a significant advancement in winter performance. Designed to cater to a broad range of vehicles – including sedans, minivans, CUVs, SUVs and trucks – the IcePeak will replace the Blizzak WS90 and DM-V2 models. It will be available in 107 sizes, ultimately covering approximately 97 percent of the US light-duty vehicle market, with the majority of sizes ready at launch.

The tyre’s development centres on delivering superior winter traction alongside improved durability and efficiency, leveraging the company’s ENLITEN technology. This integration aims to lower rolling resistance for better fuel economy and extend tyre wear life, offering long-term cost savings for drivers. Internal testing indicates the IcePeak surpasses the wear life of its predecessors while maintaining effective traction. Its compatibility extends to conventional, hybrid and electric vehicles, emphasising its modern engineering.

Key to its performance is a suite of specialised technologies. Bridgestone’s patented MultiCell compound is engineered to enhance stopping power on ice, a claim validated by the official Ice Grip certification. This certification requires performance on ice to exceed a standard reference tyre by at least 18 percent in braking tests. For snow traction, the tyre employs optimised tread blocks and full-depth 3D sipes to create additional biting edges, helping vehicles gain grip and reduce spin.

Building upon the Blizzak lineage, which spans nearly four decades of innovation, the IcePeak introduces refined design elements. Its optimised compound is formulated for added durability across multiple winter seasons without sacrificing grip. A newly unified global tread pattern incorporates several critical features: strategically placed sipes are angled to maximise the gripping edge, protrusions on tread blocks prevent water intrusion on ice and micro-grooves help clear the thin water film that forms on icy surfaces. Together, these features aim to provide drivers with reliable control in wet, snowy and icy conditions, advancing the brand’s reputation for winter safety and performance.

Ian McKenney, Senior Product Manager, Bridgestone Americas, said, “Our Blizzak tyre lineup moves from strength to strength, continually raising the standard for impressive winter weather control. With the application of ENLITEN technology, we are able to expand the tyres’ performance envelope in all directions while also delivering greater durability and reduced rolling resistance, while promoting a focus on enhanced sustainability.”
