Small weights (usually made of lead) attached to the wheel to balance the wheel and tire assembly. Most have a lip which attaches to the flange of the rim; others are pasted on the smooth side of a rim -- particularly on mag wheels; and others are wrapped around the spokes of a wheel (such as a motorcycle wheel). They are marked in fractions of an ounce or in grams.
