Abstract

Abstract:

To investigate the impact of variation in tire tread depth on vehicle performance， performance tests are conducted using tires with differing tread depth as our subjects on dry， wet， and low-adhesion road surface at the proving ground. The results indicate that the braking distance decreases as tread depth diminishes on dry surface while the trend reverses compared to dry surface on wet surface， and tread depth variation has a minor impact on braking distance on low-adhesion surface. The maximum lateral acceleration and yaw rate of the vehicle initially increase and then decrease with reducing tread depth on dry surface， peaking at 4.0 mm. The maximum yaw rate follows a similar pattern to dry surface on wet surface， but there is no clear trend in maximum lateral acceleration.

Key words: tire, tread depth, vehicle performance, experimental research
