Checking Tire Inflation Pressure - Toyota Yaris Owner's Manual

Checking tire inflation
pressure
Keep your tire inflation pressures at the
proper level.
The recommended cold tire inflation pres-
sures and tire sizes are given on page
238 in Section 8.
You should check the tire inflation pres-
sure every two weeks, or at least once a
month. And do not forget the spare!
Incorrect tire inflation pressure may waste
fuel, reduce the comfort of driving, reduce
tire life and make your vehicle less safe
to drive.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.

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 pres-
sures that are even just a few pounds
off can degrade handling and ride.
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

Uneven wear
