Vehicle Care
approximately 5 °C (40 °F) or on ice or snow
covered roads is expected. See

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.

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 for
internal combustion engine
vehicles
.
Reduced range for electric vehicles
Overinflated tyres, or tyres that have
too much air, can result in:
.
Unusual wear
.
Poor handling
.
Rough ride
.
Needless damage from road
hazards
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
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
spare, if the vehicle has one. The
compact spare cold tyre pressure should
be at 420 kPa (60 psi). See
How to Check
Use a good quality pocket-type gauge
to check tyre pressure. Proper tyre
inflation cannot be determined by
looking at the tyre. Check the tyre
inflation pressure when the tyres are
