NVH performance and steering response were evaluated by positioning eight types of longitudinal groove widths and spacing in the same tire pattern shape. In symmetrical patterns with the same center and shoulder widths, noise was reduced when the longitudinal groove width was small. Then, in asymmetric patterns, noise was reduced when the longitudinal groove area was small. Moreover, to see the pattern noise due to the actual ground distance and the distance between longitudinal grooves, we found the noise index of the pattern, and confirmed that the lesser the noise index, the lower the noise level. In terms of steering, the steering rating average(SRA) was high when the width of the longitudinal groove and the gap between the longitudinal grooves were at a certain value. Also, it was confirmed that the balance between the width of the longitudinal groove and the gap between the longitudinal grooves were important factors in determining steering characteristics. |
