Summer Tyres

High Performance Summer Tyres
This vehicle may come with 245/
40R18 (front) and 275/35R18 (rear)
high performance summer tyres.
These tyres have a special tread
and compound that are optimised
for maximum dry and wet road
performance. This special tread and
compound will have decreased
performance in cold climates, and
on ice and snow. It is recommended
that winter tyres be installed on the
vehicle if frequent driving at
temperatures below approximately
5 °C (40 °F) or on ice or snow
covered roads is expected. See
Winter Tyres 0 287.
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 0 295.

Tyre Pressure

Tyres need the correct amount
of air pressure to operate
effectively.
Vehicle Care
Caution
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.
