Introduction
Interpretation of the evaluation standard for the self-sealing performance of coated puncture self-sealing tires
| Standard dimensions | Technical requirements | Test methods |
|---|---|---|
| Static airtightness | At room temperature and low temperature, the air pressure shall not be less than 90% of the initial value. | Perform durability test according to GB/T4502. |
| Durability | Pulling out or not pulling out the nail after puncture must comply with the requirements of GB9743. | Visually check that there is no abnormality in the self-sealing layer. |
| High-speed performance | The tires that have the nails pulled out after being punctured must meet the requirements of GB9743. | Visually check that there is no abnormality in the self-sealing layer. |
Background of standard formulation and technological evolution
Coated puncture self-sealing tires improve their sealing performance after being punctured by foreign objects by coating the inner surface of the crown with self-sealing materials. Compared with ordinary tires, this type of tire has better puncture resistance and air leakage prevention characteristics.
Implementation recommendations
- Ensure that the tire pressure value recommended by the manufacturer is followed when assembling the tire.
- Regularly check the tire surface to detect and deal with punctures in a timely manner.
- It is recommended to install a tire pressure monitoring system to improve safety.
