WARNING (Continued)
.
Underinflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when the
tires are cold.
.
Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
hitting a pothole. Keep tires at
the recommended pressure.
.
Worn or old tires can cause
a crash. If the tread is badly
worn, replace them.
.
Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.

WARNING (Continued)
.
Improperly repaired tires
can cause a crash. Only the
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.
.
Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such
as snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.
20‐Inch Tires
If your vehicle has the optional
20‐inch P275/55R2 0 size
tires, they are classified
as touring tires and are
designed for on road use.
The low‐profile, wide tread
design is not recommended
for off‐road driving. See
Off-Road Driving on page 9‑7,
for additional information.
Notice: If the vehicle has
low‐profile tires, they are more
susceptible to damage from
road hazards or curb impact
than standard profile tires.
Tire and/or wheel assembly
damage can occur when
coming into contact with
road hazards like, potholes,
or sharp edged objects,
or when sliding into a curb.
The vehicle warranty does
not cover this type of damage.
Keep tires set to the correct
inflation pressure and, when
possible avoid contact with
curbs, potholes, and other
road hazards.
