The Self-sealing Tires made in China are only half the price of Michelin, Continental and Pirelli

Self-sealing tires are a type of tire that uses a special sealing compound inside to automatically repair punctures. Here is detailed information about self-sealing tires:

Working Principle
Self-sealing tires are coated internally with a special sealing compound, usually made of polymer material. When the tire is punctured (e.g., by a nail or other sharp object), the puncturing object presses against the sealing compound, which quickly flows into the puncture and solidifies, forming a seal to prevent air leakage. This process can be completed without removing the tire from the vehicle.

Composition and Structure
**Tread**: Similar to regular tires, primarily responsible for providing grip and wear resistance.
**Inner Sealing Compound**: The core part of the self-sealing tire. The sealing compound usually covers the entire inner area of the tread, with a moderate thickness to ensure it can quickly flow into the puncture when pierced.
**Reinforcement Structure**: Some self-sealing tires have an additional reinforcement layer under the tread to increase the overall strength and puncture resistance of the tire.

Advantages
1. **Immediate Repair**: Capable of repairing punctures immediately, preventing air leakage.
2. **Reduced Maintenance**: Less frequent trips to the repair shop for tire patching, saving time and costs.
3. **Increased Safety**: Effectively prevents blowouts due to air leakage during high-speed driving.
4. **Extended Lifespan**: The presence of the sealing compound can extend the tire's lifespan, reducing the likelihood of tire scrapping.

Disadvantages
1. **Effective Only for Small Punctures**: The sealing compound is mainly effective for small punctures (usually under 6mm in diameter) and is not effective for larger damages or cuts.
2. **Aging of Sealing Compound**: Over time, the sealing compound may lose its adhesiveness and repair ability, especially in extreme temperatures.
3. **Increased Weight**: Due to the sealing compound, self-sealing tires are slightly heavier than regular tires, which may affect vehicle fuel economy.
4. **Higher Cost**: The manufacturing cost of self-sealing tires is higher, making them relatively more expensive.

Usage Recommendations
**Regular Inspections**: Despite the self-sealing capability, regular tire inspections are essential to ensure the effectiveness of the sealing compound.
**Attention to Driving Conditions**: Avoid prolonged driving in extreme temperatures to extend the lifespan of the sealing compound.
**Professional Repair**: For significant tire damage, promptly visit a professional repair shop for patching or replacement.

Market Brands and Products
Many well-known tire manufacturers produce self-sealing tires, such as:
**Michelin**: Their Selfseal technology is applied to various tire models.
**Goodyear**: Offers the Duraseal series, mainly for trucks and commercial vehicles.
**Continental**: Widely applies its ContiSeal technology to passenger car tires.

Self-sealing tires provide higher safety and convenience in daily driving, making them a worthwhile option, especially for vehicles traveling in complex road conditions.
