Inflation - Tire Pressure - GMC Sierra Classic 2007 Owner's Manual

Vehicle Maximum Load on the Tire: Load on an
individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard: A label permanently attached to
a vehicle showing the vehicle's capacity weight
and the original equipment tire size and
recommended inflation pressure. See "Tire and
Loading Information Label" under Loading
Your Vehicle on page 403.
Inflation - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice: Do not let anyone tell 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 Tire and Loading Information label is attached to
the vehicle's center pillar (B-pillar), below the
driver's door lock post (striker). This label lists your
vehicle's original equipment tires and their
recommended cold tire inflation pressures. 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
Loading Your Vehicle on page 403.
When to Check
Check your tires once a month or more. Do not
forget to check the spare tire. For additional
information regarding the spare tire, see Spare
Tire on page 584.
