DUNLOP Launches SP011: The Ultimate Winter Tire for Trucks and Buses

DUNLOP, part of Sumitomo Rubber Industries, is set to launch their new studless winter tire, the SP011, in August 2026. This innovative tire is designed specifically for trucks and buses, providing superior ice start performance and extended lifespan without compromising safety. As winter logistics and transport demands increase, the SP011 addresses these challenges by ensuring reliable performance even as the tire wears down, which is crucial for maintaining safety on icy roads.

Product Overview

The SP011 is engineered for winter logistics and transport, delivering remarkable ice start capabilities while enhancing the durability needed for long-distance and long-term use. This tire is designed to not only maintain its winter capabilities after significant wear but also promotes sustainable reuse to lower costs and reduce environmental impacts, making it an invaluable asset for winter operations.

Key Features

1. Balancing Ice Start and Longevity
Utilizing a new tread pattern, DUNLOP has improved block rigidity, which enhances the tire's lifespan while increasing the edge components necessary for gripping on icy surfaces. Additionally, the tread rubber integrates eggshell materials, optimized for particle size and quantity, boosting traction for ice start performance while minimizing the reduction in durability. The results show an 8% enhancement in ice start performance compared to the previous model, SP001, and over 20% improvement in lifespan, ensuring these tires can be used longer and more effectively.

2. Maintaining Performance despite Wear
The SP011 is thoughtfully designed with optimized siping depths to prevent a decline in winter performance even as the tire wears down. This is particularly effective in maintaining critical edge components, especially in the tread center block area, ensuring that consistent performance is delivered throughout the entire winter period.

3. Quality Improvement for Retreaded Tires
DUNLOP has re-examined the case profile and bead structure to enhance the quality of retreaded tires. This redesign promotes tire reuse and contributes to running cost reduction. The new flexible profile optimizes rubber thickness at the sidewall, improving rim assembly ease, while the upgraded bead structure minimizes damage during installation, preventing bead lifting. Furthermore, for the first time, DUNLOP has introduced a 'Retread Guide Sign' in their truck and bus tire category, illustrating the optimal timing for removing tires for retreading, which consequently reduces resource use and environmental impact.

Overall Performance

The SP011 stands out not only for its advanced features but also for its commitment to safe and economical winter operations. Its comprehensive performance ensures that logistics firms can conduct operations with confidence in the tire’s longevity and reliability, thereby enhancing the overall safety in winter logistics.

Available Sizes

DUNLOP will offer the SP011 in various sizes, including those that incorporate the new profile and bead structure.

As of 2026, DUNLOP has consolidated its communication brand under one name. The brand aims to enhance the experience of all users by embodying values that support challenges, exceed expectations, and push boundaries, encapsulated in their brand statement, 'TAKING YOU BEYOND.' This philosophy reflects DUNLOP's commitment to expanding possibilities for everyone who dares to challenge themselves.

Conclusion

DUNLOP’s SP011 is not just a tire; it is a significant technological advancement in the winter tire segment for trucks and buses. Its unique balance of performance and sustainability sets a new standard in the industry, positioning DUNLOP as a leader in winter tire innovation. Expect to see the SP011 showcased at the Japan Truck Show 2026 from May 14 to 16 at Pacifico Yokohama, marking a pivotal moment for winter transportation safety and efficiency.
