Wheel Selection
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. Wheels have many bolt circle variations and some are so close that it could be possible to
attach an inappropriate wheel that does not match the axle hub.
2. Capacity. Wheel load capacity should match tire and trailer max. load ratings.
3. Offset. The relationship of the center line of the tire to the hub face of the axle should match any
replacement. Failure to match offset may result in reducing the carrying capacity of your axle.
4. Rim Contour. Replacement wheels should be direct replacements to match the rim contour.
Use only rim contours suggested by manufacturer. Failure to use correct rim contour may cause
dramatic separation of tire and wheel and could cause death or serious injury.
Attempting to modify or repair a wheel can cause unsafe conditions that may result in an explosion. Air
pressure on a weakened or cracked rim can cause death or serious injury.
