| 中文摘要: |
| 对比研究美国标准FMVSS119和FMVSS139及中国国家标准对ST拖车轮胎测试条件和方法等方面的差异，包括外缘尺寸、脱圈阻力、强度性能、高速性能、耐久性能和低充气压力耐久性能试验项目。结果表明，FMVSS139的高速性能和耐久性能测试条件较为苛刻，且增加了低充气压力耐久性试验，国内大部分轮胎企业的产品均可达到FMVSS139标准要求。 |
| 英文摘要: |
| The differences in the test conditions and methods of ST trailer tires in the American standards FMVSS119 and FMVSS139，and Chinese national standards were studied，including peripheral dimension，bead unseating resistance，strength，high-speed performance，endurance，and low air pressure endurance test items.After comparison，it was found that the test conditions of high-speed performance and endurance of FMVSS139 were more demanding，and adding low air pressure endurance test，the products of most domestic tire enterprise could met the FMVSS139 standard requirements. |
