Disclosed are a tire hardness measurement method and a tire specimen fixing device. The tire hardness measurement method according to an embodiment of the present invention comprises: a specimen cutting step of cutting a tire in a radial direction to obtain a tire specimen; a specimen mounting step of binding bead parts on both sides of the tire specimen with a fixing device to maintain the distance between the bead parts on both sides under a set measurement condition; and a hardness measurement step of measuring hardness by pressing the cut surface of the tire specimen bound to the fixing device with a needle of a hardness measuring device. One aspect of the present invention is to provide the tire hardness measurement method, which allows to accurately measure not only the hardness on the surface side of the tread, but also the hardness on the inside of the tread.
