Tires
WARNING!
Do not repair damaged tires unless
you are fully qualified and equipped
to do so.
Wheel and tire assem-
blies cannot be worked on without
proper tools and equipment, such
as: safety cages or restraining de-
vices.
Have all tire repairs per-
formed by an expert. Stand away
from the tire assembly while the ex-
pert 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,
efficient 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 Inflation Pressure
Give your tires a visual test every day,
and check inflation
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 underinflated, check
for damage to the wheel assembly.
Don’t forget to check between dual
wheels. If you find 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 deflate a warm tire to the
specified pressure.
