TIRE / WHEEL EMERGENCIES

Damaged Tires

[WARNING] An inflated tire and rim can be very dangerous when misused or
worn out. Many accidents, some fatal, have resulted from improper handling
and operation of bus rims and wheels. To help avoid personal injury and/
or property damage, get expert tire service help. To remove the wheel and
change the tire without such help, take the following precautions:
• Stand to the side and check whether the wheel assembly appears normal
by comparing it to another wheel assembly on the vehicle.
• If not fully expert on the procedures to follow, and/or not equipped with
the proper tools and equipment, do not attempt to raise the vehicle or
remove or install the tire and wheel assembly. Obtain expert tire service
help.
• Do not inflate a tire that has been run flat or is seriously low on air
without first having the tire taken off the wheel and the tire checked for
damage.
• Work on bus wheels requires proper tools, safety equipment, and special
training. Only trained people using the proper equipment should service
bus tires and wheels.
• When putting air into a tire on the vehicle, stand to the side and use a clip
on chuck and hose extension. Never add air to the tires without using an
accurate pressure gauge. Never exceed the maximum pressure capacity
shown on the tire.
[WARNING] Tire inflation pressure must not exceed the specifications of the
tire and/or wheel rim manufacturer for the specific load, speed, and applica-
tion. Tires should not be inflated above the pressure listed on the label.

Wheel And Rim Safety

Wheels and wheel components must be properly maintained to avoid adverse ef-
fects on the life of the tire and/or wheel. An inflated tire is potentially very destruc-
tive. Determine the load carrying requirements of the vehicle before selecting a tire/
wheel combination. Remember that the weakest weight carrying component of the
vehicle (i.e., the tires, wheels, axles, bearings, etc.) determines the load carrying ca-
pacity for the vehicle.
