Recently, the Europe labeling Wet Grip on Worn Tyres(WGWT) regulation has been established to ensure stability performance up to the wear limit of tyres. However, for C1 tyres, no direct correlation is identified between the Wet Grip Index (WGI) of new and worn tyres, necessitating independent testing. In this study, finite element analysis was used to predict the wet grip performance of worn tyres. The numerical modeling process accounted for variations in the tread depth, as well as the remaining groove and sipe ratios, throughout the buffing process. To validate the simulations experimentally, the trailer method was utilized for wet grip testing of tyre models, and the results were compared with numerical predictions. The findings revealed that the WGWT WGI demonstrated a correlation exceeding 80%, and the wet grip performance of worn tyres declined by approximately 30% compared with that of new tyres. |
