2.4 Wheels and Tires
Wheels
Wheels are a very important and critical component of your running gear. Inspect
them visually for cracks or elongated bolt holes whenever they are removed for any
reason. If it becomes necessary to replace the wheels on your trailer, be certain that
the replacement units match the originals in the following regards:
1. Bolt Circle. Many bolt circle dimensions are available and some vary by so little
that it might be possible to attach an improper wheel that does not match the axle hub.
Be sure to match your wheel to the axle hub.
2. Capacity. Be sure your wheels have enough load carrying capacity and pressure
rating to match the maximum load of the tire and trailer.
3. Offset. This refers to the relationship of the center line of the tire to the hub face
of the axle. Care should be taken to match a replacement wheel with the same offset
wheel as originally equipped. Failure to match offset can result in reduced carrying
capacity of your axle.
4. Rim Contour.
RIM CONTOURS!
Use only the approved rim contours as shown in the Tire and Rim
Yearbook or the tire manufacturers catalog. The use of other rim con-
tours is dangerous. Failure to use the proper rim contour can result in
explosive separation of the tire and wheel and could cause a serious
accident.
WHEEL MODIFICATIONS!
Do not attempt to repair or modify a wheel. Even minor modifications
can have a great effect. Do not install a tube to correct a leak through the
rim. If the wheel is cracked, the air pressure in the tube may cause the
pieces of the wheel to explode with great force and can cause serious
injury or death.
