CAUTION:
{
Poorly maintained and improperly used
tires are dangerous.
•
Overloading your vehicle's 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 411.
•
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 vehicle's tires are cold. See
Inflation - Tire Pressure on page 518.
•
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.
CAUTION: (Continued)
CAUTION: (Continued)
•
Worn, old tires can cause accidents. If
the tire's tread is badly worn, or if
your vehicle's tires have been
damaged, replace them.
