摘要： A rim-fitted tire witth a weight unbalance corrected in which a plurality of balance weights for correcting static unbalance are attached on an outer peripheral surface of the rim thereof at a substantially central position with respect to the widthwise dimension of the rim. Balance weights are attached at widthwise opposite ends of the rim to correct an amount of static unbalance on the basis of an amount of dynamic unbalance measured in the static-unbalance corrected state. Since the balance weights are attached on the rim in a distributed manner, the weight of each balance weight is made light, hereby reducing the centrifugal force occurring when the tire is actually used on a vehicle.
