To provide a tire unbalance correcting method capable of reducing the vibration of a vehicle in a running state.

A correction weight 14 of 50 to 80% of the amount of unbalance of a tread part 12 measured in a first attaching process is attached to the tread part 12 to correct a static imbalance W, and a correction weight 18 of 50 to 100% of the amount of unbalance of a bead part 16 measured in a second attaching process is attached to the bead part 16 to correct a dynamic unbalance M, and thereby the respective unbalances can be surely corrected. Therefore, the vibration of the vehicle in a running state can be reduced.
