When balancing wheels, keep in mind these facts:
(1) Divide the corrective weight into 4 equal pieces, 2 on the inside
rim and 2 on the outside rim.
(2) Therefore, you must always use 4 wheel. weights of the same size,
two placed on the inside rim and two on the outside rim. Use either 4A, 4B or
4C weights. DO NOT MIX SIZES.
(3) The spreading of the weights permits a consistently more accurate
balance, using only 3 sizes of weights instead of 20 sizes.
