T/JSAS 010-2021 Coated puncture-resistant self-sealing tire

Scope

Scope: This document specifies the performance testing and evaluation requirements and test methods for puncture-resistant self-sealing tires with 100 nails penetrated, including terms and definitions, test equipment and accuracy, requirements, test methods, marking, packaging, storage, and transportation requirements. This document applies to pneumatic tubeless car tires with a coating on the inner side of the tread and a leak-proof function after puncture. Main technical content: 5.1 Tire specifications, load index or rating, measuring rims, load capacity, inflation pressure, and permissible rims shall comply with the provisions of GB/T 2978. 5.2 The outer edge dimensions of new tires shall comply with the provisions of Appendix B. 5.3 The relationship between the driving speed of the tire and air pressure and load shall comply with the provisions of GB/T 2978. 5.4 The correspondence between the tire speed symbol and the maximum driving speed shall comply with the provisions of Appendix C. 5.5 The relationship between the tire load index and load capacity shall comply with the provisions of 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 requirements specified in Table 1. Table 1: Minimum breaking energy of car tires Item Nominal section width (S/mm) Radial tires Standard Enhanced Tubeless car tires Breaking energy (J) S < 160 220 439 ≥ 160 295 855. 5.6.2 Resistance to bead separation of tubeless tires: The resistance to bead separation at any test point of tubeless tires shall not be lower than the requirements specified in Table 2.
