PassengerTires
Your new vehicle comes with
high-quality tires made by
a leading tire manufacturer.
If you ever have questions about
the tire warranty and where to
obtain service, see the “Limited
Warranty, Maintenance and
Owner Assistance Information”
manual for details.
{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your tires can
cause overheating as a
result of too much exing.
You could have an air-out
and a serious accident.
SeeLoading the Vehicle
on page 8-30.
(Continued)
CAUTION (Continued)
Underin ated tires pose
the same danger as
overloaded tires.
The resulting accident
could cause serious
injury. Check all tires
frequently to maintain the
recommended pressure.
Tire pressure should be
checked when your tires
are cold. SeeInflation - Tire
Pressure on page 9-46.
Overin ated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
you hit a pothole. Keep
tires at the recommended
pressure.
