Pneumatic tire
A pneumatic tire has a side portion located between a tread portion and a bead portion which includes a decorative element. The decorative element comprises protrusions extending along the side portion and bending to form a hook. The protrusions are disposed at intervals with tips of the hooks aligned in the same direction. Each of the protrusions includes a first and second portions.
