Why Do Tire Studs Need a Carbide Pin?

Why Do Tire Studs Need a Carbide Pin?

Tire studs are designed to improve traction on icy and snowy roads. The carbide pin is the working part of the stud that directly contacts the road surface.

But why is tungsten carbide used?

1. High Hardness

Tungsten carbide is much harder than many common metals. It can maintain its shape when repeatedly contacting hard ice and frozen surfaces.

2. Excellent Wear Resistance

Tire studs experience repeated friction and impact during driving. A tungsten carbide pin resists wear, helping maintain its working tip and traction performance for longer.

3. Good Impact Resistance

Winter driving can subject tire studs to repeated impact. Properly selected carbide grades provide a balance between hardness and toughness, helping the pin withstand demanding conditions.

4. Better Ice Traction

The shape of the carbide pin affects how it contacts the ice. Round, flat, square, pointed, and customized carbide pins can be designed for different traction and durability requirements.

5. Customizable Design

Carbide pins can be customized in terms of:

▪Diameter

▪Length

▪Tip shape

▪Carbide grade

▪Tolerance

The right combination depends on the tire type, road conditions, vehicle load, and expected service life.

The carbide pin is a key component of a tire stud. Tungsten carbide provides high hardness, excellent wear resistance, and reliable performance, making it suitable for winter tire studs, truck tire studs, off-road applications, and ice racing.

Choosing the correct carbide grade and pin geometry is essential for achieving the desired traction and service life.
