Abstract
A method of correcting imbalance of a tire comprises a step of forming a coated layer on the inner surface of the tire at the point of lightest weight of the tire so as to reduce the imbalance of the tire. The coated layer has a black color substantially the same as the color of the inner surface so that it becomes difficult to recognize the correction of the weight imbalance.
