Customized Tungsten Carbide Snow Tire Studs by Tread Depth
Snow tyre studs specified against tread depth and protrusion, with a tungsten carbide core in a plated body.
Design and Construction
A tungsten carbide snow tyre stud built around one fitting rule: the stud length is chosen to match the remaining tread depth so the carbide tip protrudes by a controlled amount. The carbide core is seated in a plated metal body with a flange that seats against the tread.
How It Works
If the stud is too short it sits below the rubber and never touches ice; too long and it loads the rubber, wears quickly and can be torn out. Protrusion is set by stud length minus the hole depth, which is why the two numbers are specified together.
Applications
Winter tyre studding, retread studding, fleet winter preparation, ice-road service tyres.
Field Cases
- Fleet operator: studs matched to a fixed tread depth held protrusion across a full winter tyre set.
- Retread shop: hole depth was measured before the stud length was chosen, avoiding buried tips.
- Ice-road service: a consistent protrusion gave predictable bite on packed ice.
Performance Data
| Metric | Value / Observation |
|---|---|
| Core | Tungsten carbide |
| Body | Plated metal with seating flange |
| Fitting rule | Stud length vs hole / tread depth |
| Controlled result | Tip protrusion |
Suitable Materials
Winter and retread car tyres, light commercial tyres; rubber compounds suitable for studding.
Material Comparison: Stud Length vs Tread Depth and Protrusion
Matching the stud to the tyre. Typical industry practice; verify against local regulations:
| Factor | Short Stud | Matched Stud | Long Stud |
|---|---|---|---|
| Suitable tread depth | Shallow / worn | Medium | Deep / new |
| Resulting protrusion | Minimal | Controlled | Controlled |
| Risk if mismatched | Tip buried below rubber | Rubber overloaded | Stud torn out |
| Ice bite | Weak | Good | Good |
| Rubber stress | Low | Moderate | High if over-long |
| Typical user | Late-season retread | General winter tyre | New winter tyre |
Delivery Scope
Bulk studs; length, head style and quantity confirmed with the order.
Why Choose VPOINT
The stud and the tread depth are quoted together – protrusion is a fitted result, not a guess.

Frequently Asked Questions
How do I choose the length?
Measure the tread / hole depth first, then pick the stud length that gives the intended protrusion.
What if the stud is too long?
It overloads the rubber, wears faster and can be torn out.
What is the core made of?
Tungsten carbide seated in a plated metal body.
Is protrusion regulated?
Stud use and protrusion are regulated in some regions – check local rules.
What is checked per lot?
Stud length, flange seat and carbide core seating.
