252 Tires and wheels
Maximum Permissible
Inflation Pressure
This number is the greatest
amount of air pressure that
should ever be put in the tire
under normal driving condi­
tions.
.&_ WARNING
-Using incorrect or unmatch­ ed tires and/ or wheels or improper tire and wheel
combinations can lead to loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the
specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous
histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
-All four wheels must be fit­ ted with radial tires of the
same type, size (rolling cir­
cumference) and the same
tread pattern. Driving with different tires reduces vehi­
cle handling and can lead to
a loss of control.
-If the spare tire is not the
same as the tires that are
mounted on the vehicle -for
example with winter tires -
only use the spare tire for a
short period of time and
drive with extra care. Refit
the normal road wheel as soon as safely possible.
-Never drive faster than the maximum speed for which
the tires on your vehicle are
rated because tires that are
driven faster than their rat­
ed speed can fail suddenly.
-Overloading tires cause heat build-up, sudden tire fail ­
ure, including a blowout

- T he w heel bolts shou ld be clean an d easy
to t urn . Check fo r dirt an d corrosion on
the mating surfaces of both the w heel
and the hub. Remove all d irt from these
surfaces before remounting the whee l.
- Do not use the hexagonal socket in the
sc rewd river handle to loosen or t ighten
the whee l bolts.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
U si ng a spa re tire with a tread pattern
intended for use in a specific di rection
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection, please
note the following :
- The d irect ion of rotation is marked by an
ar­
row on the side of the t ire .
-If the spare tire has to be insta lled in the in­
correct d irect ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optimum performance cha racte r­
istics w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at­
t en tion to th is fact during wet weather and
that you adjust your speed to match road
condi tions.
- Replace the flat t ire wi th a new one a nd
have it insta lled o n you r vehicle as soo n as
pos sible to res to re the hand ling advant ages
