| Abstract: |
| The general situation of using and proving ground for snow tire was introduced，and the differences of snow grip test methods between ASTM F1805—2006，ECE R117 Appendix 7，ISO 18106：2016，GB/T 33829—2017 and GB/T 33830—2017 were analyzed. It could be seen that GB/T 33829—2017 and GB/T 33830—2017 increased the requirements for the length and width of the proving ground and the wind speed during test process，and required use of domestic SRTT. The limit of snow grip index should be determined as soon as possible for the publishment and implementation of related standards of wet grip，rolling resistance，noise and label. |
