Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you
ever have questions about your tire warranty
and where to obtain service, see your vehicle
Warranty booklet for details.
{ CAUTION:
Poorly maintained and improperly used
tires are dangerous.
• Overloading your vehicle’s tires can
cause overheating as a result of too
much flexing. You could have an
air-out and a serious accident. See
Loading Your Vehicle on page 4-34.
• 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 5-65.
