Full Cap
A full cap is a more comprehensive retreading process where new rubber is added to both the crown and the sidewalls of the tire. This contrasts with the top cap, which covers only the crown area.
Structure:
- Casing: The buffed tire casing.
- Full Cap: New tread rubber applied to both the crown and the sidewalls of the tire.
Function:
- Extended Coverage: Provides a more extensive refurbishment by adding new rubber to the entire tread area and sidewalls.
- Enhanced Protection: Offers additional protection and reinforcement to the sidewalls, potentially extending the tire’s life further than a top cap retread.
Uses:
- Heavy-Duty Applications: Often used in heavy-duty vehicles that require maximum durability and performance.
- Off-Road Vehicles: Suitable for off-road and rugged terrain where sidewall protection is crucial.
Advantages:
- Increased Durability: Extends the tire’s lifespan more than a top cap by reinforcing the sidewalls.
- Enhanced Performance: Improves overall tire performance, especially in demanding conditions.
Disadvantages:
- Cost: More expensive than a top cap retread due to the additional material and labor involved.
- Weight: Adds more weight to the tire, which can affect fuel efficiency.
