Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread lef t on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.The service lif e of your tires is
dependent on many f actors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inf lation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inf lation pressure
maintenance, it is recommended that
you have annual inspections
perf ormed once the tires reach f ive
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.
The last f our digits of the TIN (tire
identif ication number) are f ound on
the sidewall of the tire and indicate
the date of manufacture (See
on page ).619

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Check the air pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:Replace the tire when you can see
the tread wear indicator bars. The
replacement tire should be the same
sizeanddesign,mountedonthe
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surf aces. Use greater caution
while driving. Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ).
