If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
New tread
Tread wear indicator
Worn tread
You should replace the tire before the band
crosses the entire tread.
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operates normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-90 .
NOTE
Tires degrade over time, even when
they are not being used on the road. It
is recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate
the aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page 8-21 .
Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it is properly
infl ated and stored.
NOTE
The temporary spare tire condition
gradually deteriorates even if it has not
been used.
The temporary spare tire is easier to
handle because of its construction which
is lighter and smaller than a conventional
tire. This tire should be used only for an
emergency and only for a short distance.
Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-9 .
CAUTION

Do not use your temporary spare tire
rim with a snow tire or a conventional
tire. Neither will properly  t and could
damage both tire and rim.

The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.

The temporary spare tire is for limited
use, however, if the tread wear solid-
band indicator appears, replace the tire
with the same type of temporary spare
(page 6-35 ).
