1) Tread wear indicator
Each tire incorporates a tread wear indicator, which
becomes visible when the depth of the tread grooves
decreases to 0.063 in. (1.6 mm). A tire must be re-
placed when the tread wear indicator appears as a
solid band across the tread.

NOTE
For safety, inspect tire tread regularly and replace
the tires before their tread wear indicators become
visible.
Maintenance and service
When a tire's tread wear indicator becomes vis-
ible, the tire is worn beyond the acceptable limit
and must be replaced immediately. With a tire
in this condition, driving at high speeds in wet
weather can cause the vehicle to hydroplane.
The resulting loss of vehicle control can lead to
an accident.
