Our Design and Testing Process
Our step-by-step comprehensive process:
- Target Setting – Define performance and regulatory goals.
- Concepting and 3D Modelling – Create innovative designs using advanced techniques.
- Novelty Research – Ensure unique designs that meet market demands.
- Stud Hole Design – Optimize for secure retention and functionality.
- Simulation – Analyze forces and retention for optimal performance.
- Stud Placement – Determine the ideal number and arrangement of studs for maximum grip and compliance.
- Assistance in test tire manufacturing – From compounding to construction and tire studding, we support every step.
- Prototyping and Testing – Manufacture experimental studs, conduct rigorous indoor/outdoor testing, and iterate based on results.
Our goal is to create studs that enhance safety and performance while minimizing environmental and financial costs. Through professional design and development, we achieve:
- High levels of grip on icy surfaces.
- Compliance with type approval requirements.
- Long-lasting comfortable tires with reduced noise and road wear.
With our expertise, you can trust that your studded tire solution will excel in performance, durability, and reliability.
Why Choose Us?
Integrated Tire & Stud Design +
Studs alone don’t make a high-performing studded tire. The seamless integration of studs and tire design ensures optimal performance. By designing them together, we achieve perfect synergy. With decades of expertise in tire development and testing, we deliver superior results.
Collaboration & Partnership +
We work closely with customers and stakeholders, including stud manufacturers, studding machine suppliers, legislators, universities, and IP agencies. We have a proven track record of collaboration with these stakeholders to ensure high-quality outcomes.
Comprehensive Testing +
With the support of our BD Testing subsidiary, we perform rigorous tests, including: type approval tests (e.g., overrun tests), ice grip tests, stud retention tests, and wear tests. Our precise testing ensures reliability and actionable insights.
CITYSTUD Technology – Winter Tire Solutions
At Black Donuts, we offer advanced winter tire solutions featuring our innovative CITYSTUD technology. Designed to provide superior grip on ice while minimizing road wear, noise, and manufacturing costs, CITYSTUD studs are engineered for optimal performance and comfort.
Thanks to a breakthrough pin joint technique, we can use alternative materials like polymers, making the stud lighter and more road-friendly. This approach also allows for a variety of materials, shapes, and colors, offering more flexibility in design. By incorporating recycled plastic, we reduce the environmental impact while enhancing tire performance in both winter and rainy conditions.
At Black Donuts, we have harnessed a special plastic that boasts exceptional strength, recyclability, and remarkable lightweight properties. Moreover, these studs, made from recycled plastic, provide durable grip on icy surfaces. By offering lighter and more road-friendly studded tires, we aim to address not only winter-related issues caused by traditional non-studded tires but also the challenges faced during rainy conditions.
