Checking And Replacing Tires - Toyota Coaster 2015 Owner's Manual

The following instructions for checking
tire inflation pressure should be ob-
served:
The pressure should be checked only
D
when the tires are cold. If your ve-
hicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire inflation
pressure reading.
Always use a tire pressure gauge.
D
The appearance of a tire can be mis-
leading. Besides, tire inflation pressur-
es that are even just a few pounds off
can degrade ride and handling.
Do not bleed or reduce tire inflation
D
pressure after driving. It is normal for
the tire inflation pressure to be higher
after driving.
Be sure to reinstall the tire valve
D
caps. Without the valve caps, dirt or
moisture could get into the valve core
and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.
CAUTION
Keep your tires properly inflated.
Otherwise, the following conditions
may occur and cause an accident re-
sulting in death or serious injuries.
Low tire pressure (underinflation)—
Excessive wear
D
Uneven wear
D
Poor handling
D
Possibility of blowouts from an
D
overheated tire
Poor sealing of the tire bead
D
Wheel deformation and/or tire sepa-
D
ration
A greater possibility of tire damage
D
from road hazards
High tire pressure (overinflation)—
Poor handling
D
Excessive wear
D
Uneven wear
D
A greater possibility of tire damage
D
from road hazards

Treadwear indicator

CHECKING YOUR TIRES
Check the tire's tread for treadwear in-
dicators. If the indicators show, replace
the tires. The location of treadwear in-
dicators is shown by the "TWI" or "D"
marks, etc., molded on the sidewall of
each tire.
The tires on your Toyota have built−in
treadwear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
