Abstract: A tire inspection system includes a data acquisition unit, a user operation acknowledgment unit, and a display processing unit. The data acquisition unit acquires data for groove depth measured by a groove depth measurement instrument for measuring a groove depth of a tire. The user operation acknowledgment unit acknowledges a user operation input provided by a worker to indicate whether an uneven wear is identified in the tire for which the data for groove depth is acquired by the data acquisition unit. The display processing unit displays, when a user operation input acknowledged by the user operation acknowledgment unit indicates that an uneven wear is identified, a schematic diagram corresponding to a plurality of types of uneven wear. The user operation acknowledgment unit acknowledges a user operation input for the worker's selection of a type of uneven wear from the schematic diagram.

Abstract: A tire inspection system includes a data acquisition unit, a groove depth determination unit, and an alert processing unit. The data acquisition unit acquires data for groove depth derived from measuring a groove depth of a tire mounted on a vehicle a plurality of times per groove by using the measurement instrument. The groove depth determination unit determines whether a per-groove difference in groove depth acquired by the data acquisition unit is equal to or larger than a predetermined value. When the groove depth determination unit determines that the difference is equal to or larger than the predetermined value, the alert processing unit outputs an alert to indicate that the groove depth should be measured again.
