WARNING
DO NOT repair damaged tires unless
you are fully qualified 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.
Checking Inflation Pressure
Low pressure is a tire’s worst enemy.
Underinflation allows tires to flex
improperly, causing high temperatures to
build up. Heat causes early tire damage
such as flex break, radial cracks, and ply
separation. Low pressure may affect
control of your vehicle, especially at the
front wheels. Most tire wear problems are
caused by underinflation as the result of
slow leaks, so check tire pressure
regularly. Lower tire pressure does not
provide better traction on ice or snow. 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.
WARNING
DO NOT operate a vehicle with under-
inflated tires. The extra heat caused by
underinflation can cause sudden tire
failure such as a tire fire or blow out,
which can cause an accident resulting
in death or personal injury. Low pres-
sure may affect control at the front
wheels, which could result in an acci-
dent involving death or personal injury.
Keep your tires inflated to the manu-
facturer's recommended air pressure.
