TIRES AND WHEELS PREVENTIVE MAINTENANCE
– 200 – Y53-6033
Regional Haul (R05/10)
Speed Restricted Tires
WARNING! This vehicle may be equipped with
speed restricted tires. Check each tire’s side-
wall for maximum rated speed. Vehicle should
not be operated at sustained speed in excess
of maximum rated speed. Failure to comply
with these speed restrictions could cause
sudden tire failure which can result in death,
personal injury or property damage.
Tire Inspection and Replacement
Visually inspect your tires frequently for any abnormal
conditions such as scrapes, bulges, and uneven wear.
This must be done immediately after known or suspected
contact with an object in the road, with a pothole, road
irregularity or after severe braking. Refer these conditions
to an Authorized Tire Service Center for repair or replace-
ment. Never drive on a tire if such conditions appear.
If the tire looks underinflated, stand off to the side and
check for damage to the wheel assembly. This can be
done by visually comparing the wheel in question to other
wheels on the vehicle. For dual wheel assemblies, check
between the wheels for damage. If any damage is found,
or you suspect damage, do not attempt further repair. Call
for expert tire service.
Tire Inflation and Loading
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. And low pressure
may affect control of your vehicle, especially at the front
wheels.
WARNING! Do not operate vehicle with under-
inflated tires. The extra heat caused by under-
inflation can cause sudden tire failure such as
a tire fire or blow out which can cause an acci-
dent resulting in death or personal injury. Low
pressure may affect control at the front
wheels, which could result in an accident and
serious injury. Keep your tires inflated to the
manufacturer's recommended air pressure.
