NOTE
Loss of correct wheel alignment* causes the tires to wear on one
side and reduces the vehicle’s running stability. Contact your
SUBARU dealer if you notice abnormal tire wear.
* : The suspension system is designed to hold each wheel at a certain alignment
(relative to the other wheels and to the road) for optimum straight-line stability and
cornering performance.

Wear indicators
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 replaced when the tread wear indicator appears as a solid
band across the tread.

WARNING
When a tire’s tread wear indicator becomes visible, the tire is
worn beyond the acceptable limit and must be replaced immedi-
ately. 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.
NOTE
For safety, inspect the tire tread regularly and replace the tires be-
fore their tread wear indicators become visible.
