Tire characteristic value measurement device and tire characteristic value measurement system

A tire characteristic value measurement device (100) comprises support arms (124) provided to an upward/downward moving means (111-121). The support arms (124) support, from below, a tire (T) on a roller conveyor (101) and each have electrical insulating properties. The tire characteristic value measurement device (100) further comprises an electrical resistance value detecting means (125-139) provided to the upward/downward moving means (111-121). The electrical resistance value detecting means (125-139) detects an electrical resistance value of the tire T supported by the support arms (124).
