Abstract:
1. A wheel balance adjustment device characterized by comprising: first calculating means which calculates an attachment position and correction weight amount of a correction weight which counteract a weight imbalance of a tire assembled to a rim; first comparing means which compares a rim peripheral direction length corresponding to a tire peripheral direction ground contact length of a ground contact region, at which the rim-assembled tire contacts a road surface, with a rim peripheral direction length of the correction weight; and second calculating means which, in a case in which the rim peripheral direction length of the correction weight is shorter than the rim peripheral direction length corresponding to the ground contact length, and in a case in which the rim peripheral direction length of the correction weight is longer than the rim peripheral direction length corresponding to the ground contact length that is a case in which a portion by which the correction weight is longer than the rim peripheral direction length corresponding to the ground contact length is not more than a predetermined value, calculates attachment positions of the correction weight, which has been divided, in order to make an imbalance that occurs when a portion of the weight imbalance portion of the rim-assembled tire is in ground contact smaller by dividing the correction weight into a plurality of units and attaching the units to the rim periphery with dispersing in the rim peripheral direction.
