CAUTION:
{
•
Poorly maintained and improperly
used tires are dangerous.
•
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and
a serious accident. See Loading Your
Vehicle on page 392.
•
Underinflated 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. See Inflation - Tire
Pressure on page 488.
CAUTION: (Continued)
CAUTION: (Continued)
•
Overinflated 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, old tires can cause accidents.
If your tread is badly worn, or if
your tires have been damaged,
replace them.
See High-Speed Operation on page 490
for inflation pressure adjustment for high
speed driving.
