NOTICE
Low profile tire like 215/45ZR17
may have greater damage than
usual tires to its tire wheel
when receiving impact from the
road surface. Therefore,
attention to the followings.
z Be sure to use with proper
tire pressure. If the tire pres-
sure is low, the tire may
have a greater damage. For
detailed information
tire pressure, see page 239.
z Avoid
driving onto
sharp–edged objects and oth-
er road hazards. Failure to
do so can lead to severe tire
damage.
The effectiveness of snow tires is
lost if the tread wears down below
4 mm (0.16 in.).

If you have tire damage such as
cuts, splits, cracks deep enough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be replaced.
If a tire often goes flat or cannot be
properly repaired due to the size or
pay
location of a cut or other damage, it
should be replaced. If you are not
sure, consult with your Scion dealer.
If air loss occurs while driving, do not
continue driving. Driving even a short
distance can damage a tire beyond
about
repair.
Any tires which are over 6 years
high,
old must be checked by a qualified
technician even if damage is not
obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires.
Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label. For details about the
sidewall of the tire and the Certifica-
tion Label, see pages 146 and 143.
