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 tires. Always
inspect tires before use. See

Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:

The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire

recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity. See
.
How the vehicle is loaded
affects vehicle handling and ride

with more weight than it was
designed to carry.
When to Check
Check the tires once a month or

spare, if the vehicle has one.
The cold compact spare tire
pressure should be at 420 kPa
(60 psi). See
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
