WARNING
.
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 Vehicle
Load Limits on page 9‑12.

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.
See Tire Pressure for
High-Speed Operation on
page 10‑50 for inflation pressure
adjustment for high-speed
