Saturn 2009 ASTRA - Manual (Page 231)

Vehicle Capacity Weight :
The number of designated
seating positions multiplied by
150 lbs (68 kg) plus the
rated cargo load. See Loading
the Vehicle on page 8-30.
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 the Vehicle on
page 8-30.
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 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 Loading
the Vehicle on page 8-30.
How you load your vehicle
affects vehicle handling and ride
comfort. Never load your
vehicle with more weight than it
was designed to carry.
