Tires
WARNING!
Do not repair damaged tires unless
you are fully qualied and equipped to
do so. Wheel and tire assemblies can
-
not be worked on without proper tools
and equipment, such as: safety cages
or restraining devices. Have all tire re
-
pairs performed by an expert. Stand
away from the tire assembly while the
expert is working. Failure to do this
may result in death or injury.
Your tires are a very important part of
your vehicle’s whole braking system.
How fast you can stop depends in
large measure on how much friction
you get between the road and your
tires. In addition, keeping your tires in
good condition is essential to the safe,
efcient operation of your vehicle.
Regular, frequent inspection and the
right care
will give you the assurance
of safe and reliable tire operation.
Here are some tips on maintaining
your tires.
Checking Ination
Pressure
Give your
tires a visual test every day,
and check ination with a gauge every
week:
• When checking tire pressure,
inspect each tire for damage to
sidewalls, cuts, cracks, uneven
wear, rocks between duals, etc. If
a tire appears underinated, check
for damage to the wheel assembly.
Don’t forget to check between dual
wheels. If you nd wheel damage,
have an expert tire service repair
it.
• Maximum tire pressure will be
indicated on the sidewall of a tire.
• Check pressure only when the
tires are cool. Warm or hot tires
cause pressure buildup and will
give you an inaccurate reading.
So never deate a warm tire to the
specied pressure.
