Tire and Wheel Inspection
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 wheel is considered.
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 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 centerline 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 – WARNING: Use only the approved rim contours as shown in the "Tire and Rim Yearbook" or the tire manufacturers catalog. The use of other rim contours 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.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 RIM IS CRACKED, THE AIR PRESSURE IN THE TUBE MAY CAUSE THE PIECES OF THE RIM TO EXPLODE WITH GREAT FORCE AND CAN CAUSE SERIOUS INJURY OR DEATH.
