Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice: Neither tire
underinflation nor
overinflation is good.
Underinflated tires, or
tires that do not have
enough air, can result in:
. Tire overloading and
over-heating which
could lead to a blowout.
. Premature or
irregular wear.
. Poor handling.
. Reduced fuel economy.
Overinflated tires, or tires
that have too much air, can
result in:
. Unusual wear.
. Poor handling.
. Rough ride.
. Needless damage from
road hazards.
A vehicle-specific Tire and
Loading Information label
is attached to the vehicle.
This label shows the vehicle's
original equipment tires and the
correct inflation pressures for
the tires when they are cold.
The recommended cold tire
inflation pressure, shown on
the label, is the minimum
amount of air pressure needed
to support the vehicle's
maximum load-carrying capacity.
For additional information
regarding how much weight
the vehicle can carry, and an
example of the Tire and Loading
Information label, see Vehicle
Load Limits on page 9‑25.
How you load the vehicle
affects vehicle handling and
ride comfort. Never load the
vehicle with more weight than
it was designed to carry.
When to Check
Check the tires once a month
or more.
Do not forget to check the
pressure of the spare tire, if the
vehicle has one. See Full-Size
Spare Tire on page 10‑97 for
additional information.
