摘要
A tire ground contact characteristic measuring method according to the present invention includes: a reproduction step of reproducing a transient change in a tire attitude that occurs during travel of an actual vehicle on a tire; a stress measurement step of causing stress measuring portion embedded on a rotatable rotary drum to measure stress that is applied to the tire in contact with the rotary drum that is rotationally driven; and a calculation step of calculating tire ground contact characteristics, which are characteristics of a ground contact region of a tread surface of the tire in contact with the rotary drum on the basis of the stress measured by the stress measuring portion. The tire ground contact characteristics calculated in the calculation step are tire ground contact characteristics of the tire corresponding to the tire attitude of the actual vehicle at each point in time during a period where the transient change occurs.
