Your new vehicle comes with
high-quality tires made by a
leading tire manufacturer. If
you ever have questions about
your tire warranty and where to
obtain service, see your vehicle
Warranty booklet for details. For
additional information refer to
the tire manufacturer.
Poorly maintained and
improperly used tires are
dangerous.
Overloading the tires can
cause overheating as a result
of too much flexing. There
could be a blowout and a
serious crash. See
Under inflated 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.
Over inflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact
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

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.
