WARNING
. Poorly maintained and
improperly used tires are
dangerous.
. Overloading your tires can
cause overheating as a result
of too much flexing. You
could have a blowout and a
serious accident. See
Vehicle
Load Limits on page 9 ‑ 23 .

WARNING (Continued)
. 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 your
tires are cold.
.
Over inflated 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.
. Worn or old tires can cause a
crash. If your tread is badly
worn, replace them.
. Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
(Continued)
WARNING (Continued)
. Improperly repaired tires can
cause a crash. Only your
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.
