Colored dots on sidewall
by: Harvey Brodsky

Tire manufactures use colored dots in the manufacturing process for many purposes, but generally they are “uniformity marks.” Tires are almost perfectly round, but not quite. Uniformity marks help tire technicians identify they “not quite” part. This information is useful when mounting the tires on wheels.
