Introduction
1. Background and significance of the standard
GB/T14646-2025 "Passenger car retread tire" national standard is a comprehensive revision of the 2007 version, mainly optimizing the technical requirements, test methods and markings for retread tires. With the rapid development of the automotive industry and the improvement of environmental protection concepts, retread tires are of great significance in saving resources and reducing production costs.
2. Comparison of standard frameworks
| Standard dimensions | Requirements of the 2007 edition | New requirements of the 2025 edition |
|---|---|---|
| Tire selection criteria | No clear limit on the number of retreads | Clearly stipulates that retreading is not allowed |
| Tire body inspection | Only inflation pressure inspection is required | Low air pressure test is added (see 5.5) |
| Dimensional requirements | No clear exception for snow tires | The outer diameter of snow tires is allowed to increase by 1% |
3. Detailed explanation of technical requirements
3.1 Preparation before retreading
Before retreading, ensure that the tires are clean and dry, and perform inflation inspection on each tire, with a pressure range of 150~200 kPa. For damaged tires, it is recommended to patch them first and then perform inflation inspection.
3.2 Inspection after retreading
After retreading, it is necessary to test the tires on the tire inspection machine at the original marked pressure to ensure that there are no defects. In particular, retreaded tires should not be used for steering wheels, and their use limits should be strictly controlled.
4. Implementation suggestions
- Enterprise level:Establish a complete retreading process and quality management system, and equip with professional testing equipment.
- Industry level: Promote the dissemination of standards and strengthen industry self-discipline and supervision.
- User level: Consumers should choose regular channels to purchase refurbished tires and check the tire status regularly.
