Scope

Scope: This document specifies the performance testing and evaluation requirements and test methods for coated puncture-sealed tires that can withstand 100 nail penetrations, including terms and definitions, test equipment and accuracy, requirements, test methods, marking, packaging, and storage and transportation requirements. This document applies to pneumatic tubeless car tires with a coated inner side and puncture-sealing function. Main technical content: 5.1 Tire specifications, load index or rating, measuring rims, load capacity, inflation pressure, and allowable rims shall comply with GB/T 2978. 5.2 The outer edge dimensions of new tires shall comply with Appendix B. 5.3 The relationship between the tire's driving speed and air pressure and load shall comply with GB/T 2978. 5.4 The correspondence between the tire's speed symbol and maximum driving speed shall comply with Appendix C. 5.5 The relationship between the tire's load index and load capacity shall comply with Appendix D. 5.6 Safety performance: 5.6.1 Tire strength performance: For car tires, the strength test at each test point shall not be lower than the specified value in Table 1. 5.6.2 Tubeless tire demounting resistance: For tubeless tires, the demounting resistance at any test point shall not be lower than the specified value in Table 2. 5.6.3 Static air tightness performance: 5.6.3.1 Requirements for static air tightness performance at room temperature: After completing the test under room temperature conditions, the measured tire air pressure shall not be lower than 92% of the initial air pressure. 5.6.3.2 Requirements for static air tightness performance at low temperature: After completing the test under low temperature conditions, the measured tire air pressure shall not be lower than 92% of the initial air pressure. 5.6.4 Durability performance: 5.6.4.1 After puncture, the tire pressure of puncture-sealed tires shall not be lower than 95% of the specified in
