It is well-known that there is a close relationship between the friction of the tire and the viscoelasticity of the tread rubber, especially loss tangent tan δ in the high friction frequency band (10<sup>2</sup>-10<sup>6</sup>Hz). But it has not been verified under the real frequency and temperature conditions. In this respect, the ultrasonic (high frequency) viscoelasticity measuring method using surface reflection wave was investigated recently.<br>In this report, the relationship between friction coefficient and tan δ, measured by the ultrasonic viscoelasticity measuring method using surface reflection wave, is shown.<br>Furthermore, the high frequency vibration is found to exist during slip of rubber on a rough glass plate.<br>The ultrasonic viscoelasticity sensor for a tire is expected to be a tool for the quality lifecycle management and the safety of automotive vehicles.
