Doublestar Tire EV-Specific Tire Earns National Patent-Intensive Product Certification with 23 Patents

Recently, the National Patent-Intensive Product Filing and Certification Platform announced its annual certification list. The EV-specific tire independently developed by Doublestar Tire was successfully selected, earning the National Patent-Intensive Product Certification, with patent coverage and technical sophistication reaching a domestically leading level in the industry.

Patent-Intensive Product Certification

Patent-intensive product certification is based on a company's independent core patents, subject to rigorous standard review with focus on patent density, technological innovation, and market value. It serves as an important indicator of a company's core technological strength. This selection represents a fruitful payoff of Doublestar's years of deep cultivation in the new energy tire sector, and a vivid reflection of Chinese tire companies winning discourse power through independent innovation.

23 Patents, Six-Dimensional Performance Breakthrough

Compared to ICE vehicles, new energy vehicles feature higher startup torque, greater instantaneous load, and increased curb weight, posing greater challenges for tires in terms of load-bearing, grip, and wear resistance.

Doublestar Tire rose to the challenge, conducting technical research across six dimensions: load-bearing, grip, rolling resistance, noise, wear, and safety. The developed EV-specific tire applies 23 independent patents, covering structural design, tread pattern optimization, noise reduction, and other key areas. The application of reinforced structure, ultra-solid ring armor, new composite materials, and silent foam noise reduction technologies enables the product to achieve multiple performance breakthroughs, delivering a safer, more durable, quieter, and longer-range driving experience.

Leveraging high patent density, strong technical barriers, and outstanding industrial driving capability, the product has successfully been supplied to multiple mainstream NEV manufacturers with stable delivery and outstanding market performance.

Doublestar Tire stated that it will continue to increase R&D investment in the new energy tire field, drive high-quality development through core patent technology, and create more high-value-added innovative products to provide strong support for the NEV industry's supply chain upgrade.
