Abstract: In order to evaluate the tire grip performance on both dry and wet roads from the angle of tire grounding characteristics, ten 205/55R16 tires from different manufacturers are studied. The overall footprint of tire is divided into three parts: shoulder region; transition region and central region, and tire grounding test is conducted to get the parameters of its grounding characteristics. Then a correlation analysis is performed to single out the high correlated grounding parameters and the quantitative relationships between grounding parameters and tire grip performance on both dry and wet grounds are revealed by using principal component analysis. The results show that good fitting results are achieved of the regression equations for the grip performance of tire on both dry and wet grounds characterized by tire grounding parameters, and the outcome of the research can play a good guiding role in the structural design of high-performance tires.

Key words: radial tire, tire grounding characteristics, dry and wet grounds, grip performance, correlation analysis, principal component analysis
