Tire Pressure - Buick 2010 LaCrosse Owner's Manual

9-56 Vehicle Care

Tire Pressure

Tires need the correct amount
of air pressure to operate
effectively.
Do not let anyone tell
Notice:
you that under inflation or
over inflation is all right. It is
not. If your tires do not have
enough air (under inflation),
you can get the following:
Too much flexing
Too much heat
Tire overloading
Premature or
irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air
(over inflation), you can get
the following:
Unusual wear
Poor handling
Rough ride
Needless damage from
road hazards
A vehicle specific Tire and
Loading Information label is
attached to your vehicle. This
label shows your vehicle's
original equipment tires and the
correct inflation pressures for
your 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
your vehicle's maximum load
carrying capacity.
For additional information
regarding how much weight
your vehicle can carry, and an
example of the Tire and Loading
Information label, see Vehicle
Load Limits on page 8 12. How
you load your vehicle affects
vehicle handling and ride
comfort. Never load your vehicle
with more weight than it was
designed to carry.
When to Check
Check your tires once a month
or more. Do not forget to check
the compact spare tire, if the
vehicle has one. The compact
spare should be at 60 psi
(420 kPa). For additional
information regarding the
compact spare tire, see
Compact Spare Tire on
page 9 76.
