Wheel Selection
Wheels are a very important and critical component of your running gear
system. When specifying or replacing your trailer wheels it is important that
the wheels, tires, and axle are properly matched. The following characteristics
are extremely important and should be thoroughly checked when replacement
wheels are considered.
1. Bolt Circle. Many bolt circle dimensions are available. 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. Make sure that the 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 any replacement
wheel with the same offset wheel as originally equipped. Failure to
match offset can result in reducing the load carrying capacity of your
axle.
4. Rim Contour.
CAUTION
Replacement tires must meet the same specifications as the
originals. Mismatched tires and rims may come apart with explosive
force and cause personal injury to yourself or others. Mismatched
tires and rims can also blow out and cause you to lose control and
have an accident which can result in serious injury or death.
