PROBLEM TO BE SOLVED: To provide a measuring method of tread shape of tire capable of precisely measuring a surface shape of a tread while eliminating temperature dependency and a tread shape measurement apparatus used therefor.SOLUTION: The measuring method of tread shape of tire measures a surface shape of a tread of a tire T by using a tread shape measurement apparatus 1. The tread shape measurement apparatus 1 includes: a peripheral wall 7 for enclosing the periphery of the laser displacement gauge; and a temperature controller 6 that controls the temperature inside the peripheral wall 7. With this, variation in the output from the laser displacement gauge due to temperature variation is eliminated.

    【課題】温度依存性を解消して、トレッドの表面形状を精度良く測定するタイヤのトレッド形状測定方法、及びそれに用いるトレッド形状測定装置を提供する。【解決手段】レーザー変位計を有するトレッド形状測定装置1を用いてタイヤTのトレッドの表面形状を求める測定方法において、トレッド形状測定装置1は、レーザー変位計の周囲を囲む周囲壁7を具え、周囲壁7の内部を、温調器6によって温度管理する管理工程を有する。これにより、温度変化によるレーザー変位計の出力変動が抑制される。【選択図】図1
