Tyre Pressure - Cadillac XT4 Owner's Manual

Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop surface
cracks in the tread area at
temperatures below -7 °C (20 °F).
Always store high performance
summer tires indoors and at
temperatures above -7 °C (20 °F)
when not in use. If the tires have
been subjected to -7 °C (20 °F) or
less, let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tyres. Always inspect
tyres before use. See Tyre Inspection
0 327.

Tyre Pressure

Tyres need the correct amount of
air pressure to operate effectively.
Warning
Neither tyre underinflation nor
overinflation is good.
Underinflated tyres, or tyres
that do not have enough air,
can result in:
Tyre overloading and
overheating, which could lead
to a blowout.
Premature or irregular wear.
Poor handling.
Reduced fuel economy.
Overinflated tyres, or tyres that
have too much air, can result in:
Unusual wear.
Poor handling.
Rough ride.
Needless damage from road
hazards.
VEHICLE CARE
The Tyre and Loading Information
label on the vehicle indicates the
original equipment tyres and the
correct cold tyre inflation
pressures. The recommended
pressure is the minimum air
pressure needed to support the
vehicle's maximum load carrying
capacity. See Vehicle Load Limits
0 200.
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 pressure of the tyres
once a month or more. Do not
forget the compact spare, if the
vehicle has one. The compact
spare cold tyre pressure should be
at 420 kPa (60 psi). See Compact
Spare Tyre 0 346.
