TYRES AND WHEELS
If you have a flat tyre, see "Flat tyre" in the "6. In case
of emergency" section.
TYRE INFLATION PRESSURE
Periodically check the pressure of the tyres, includ-
ing the spare. An incorrect tyre pressure may ad-
versely affect tyre life and vehicle handling. The tyre
pressure should be checked when tyres are COLD.
Tyres are considered COLD after the vehicle has
been parked for 3 or more hours, or driven less than
1.6 km (1 mile). COLD tyre pressures are shown on
the tyre placard.
Insufficient pressure can lead to an overheating of
the tyre and subsequent internal damage. At high
speeds, this could result in tread separation and
even bursting of the tyre.
TYPES OF TYRES
CAUTION
When changing or replacing tyres, be sure all four
tyres are of the same type (that is, summer, all
season or snow) and construction. An approved
dealer or qualified workshop may be able to help
you with information about tyre type, size, speed
rating and availability.
Replacement tyres may have a lower speed rating
than the factory equipped tyres, and they may not
match the potential maximum vehicle speed. Never
exceed the maximum speed rating of the tyre.
All season tyres
RENAULT specifies all season tyres on some models
to provide good performance all year, including
snowy and icy road conditions. All season tyres are

Maintenance and do-it-yourself
identified by ALL SEASON and/or M&S on the tyre
sidewall. Snow tyres have better snow traction than
all season tyres and may be more appropriate in
some areas.
Summer tyres
RENAULT specifies summer tyres on some models
to provide superior performance on dry roads. Sum-
mer tyre performance is substantially reduced in
snow and ice. Summer tyres do not have the tyre
traction rating M&S on the tyre sidewall.
If you plan to operate your vehicle in snowy or icy
conditions, RENAULT recommends the use of snow
or all season tyres on all four wheels.
Snow tyres
If snow tyres are needed, it is necessary to select
tyres equivalent in size and load rating to the origi-
nal equipment tyres. If you do not, it can adversely
affect the safety and handling of your vehicle.
Generally, snow tyres have lower speed ratings than
factory equipped tyres and may not match the po-
tential maximum vehicle speed. Never exceed the
maximum speed rating of the tyre. If you install
snow tyres, they must be the same size, brand, con-
struction and tread pattern on all four wheels.
For additional traction on icy roads, studded tyres
may be used. However, some states and provinces
prohibit their use. Check local, state and provincial
laws before installing studded tyres. Skid and trac-
tion capabilities of studded snow tyres on wet or
dry surfaces may be poorer than that of non-stud-
ded snow tyres.
Four-Wheel Drive (4WD) model
CAUTION
Always use tyres of the same type, size, brand,
construction (bias, bias-belted or radial), and
tread pattern on all four wheels. Failure to do
so may result in a circumference difference
between tyres on the front and rear axles
which will cause excessive tyre wear and may
damage the transmission, transfer case and
differential gears.
ONLY use spare tyres specified for the 4WD
model.
If excessive tyre wear is found, it is recommended
that all four tyres be replaced with tyres of the same
size, brand, construction and tread pattern. The tyre
pressure and wheel alignment should also be
checked and corrected as necessary. Contact an
approved dealer or qualified workshop.
TYRE CHAINS
Use of tyre chains may be prohibited according to
location. Check the local laws before installing tyre
chains. When installing tyre chains, make sure that
they are of proper size for the tyres on your vehicle
and are installed according to the chain manufac-
turer's instructions.
Use chain tensioners when recommended by the
tyre chain manufacturer to ensure a tight fit. Loose
end links of the tyre chains must be secured or re-
moved to prevent the possibility of whipping action
damage to the wings or underbody. If possible,
avoid fully loading your vehicle when using tyre
chains. In addition, drive at a reduced speed. Other-
