Wheel size Minimum space required
16 in .7 in (17 mm)
17 in .2 in (4 mm)
18 in .2 in (4 mm)
A tire chain that provides the specified amount of
space will provide the necessary clearance be-
tween the tire and the closest vehicle suspension
or body component. The minimum clearances are
determined using the factory-equipped tires.
Other types may damage your vehicle. Use chain
tensioners when recommended by the tire chain
manufacturer to ensure a tight fit. Loose end links
of the tire chain must be secured or removed to
prevent the possibility of whipping action dam-
age to the fenders or underbody. If possible,
avoid fully loading your vehicle when using tire
chains. In addition, drive at a reduced speed.
Otherwise, your vehicle may be damaged and/or
vehicle handling and performance may be ad-
versely affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
tire chains in such conditions can cause damage
to the various mechanisms of the vehicle due to
some overstress.

WARNING
●After rotating the tires, check and
adjust the tire pressure.
●Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
●Do not include the spare tire in
the tire rotation.
●For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

CAUTION
●Do not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause dam-
age to the vehicle.
●Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not drive
the vehicle through an automatic car
wash since it may get caught.
