Tire Pressure - Cadillac CTS Owner's Manual

10-74 Vehicle Care

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
.
overheating 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.
The Tire and Loading
Information label on the
vehicle indicates the original
equipment tires and the correct
cold tire inflation pressures.
The recommended pressure is
the minimum 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 12.
How the vehicle is loaded
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 the
compact spare tire, if the vehicle
has one. The cold compact
spare should be at 420 kPa
(60 psi). See Compact Spare
Tire on page 10 109.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
