Choosing the Right Trailer Tire and Trailer Wheel: A great deal of thought and consideration should be given when selecting trailer wheels. Important choices must be made from the various trailer wheels on the market. When combining trailer wheels, tires, hubs and axles, the load carrying capacity is limited to whichever component has the lowest capacity. Load capacities relate specifically to generally accepted standard axle applications for conventional trailers used in normal highway service, loaded equally side-to-side. Unusual axle configurations, unequal fore and aft loading, or overload conditions can cause premature failure of wheels, tires and/or other parts.
How To Determine Trailer Tire Bolt Pattern: Match wheels to hubs by the number of bolts and bolt circle. To determine the bolt circle on trailer wheels with an even number of bolt holes, measure center-to-center on bolt holes directly across from each other on the diameter (Example: 8 on 6 1/2 would mean 8 bolt holes with 6 1/2" center-to-center diameter). On odd number bolt wheels, measure any bolt hole center to the point halfway between bolt holes on the diameter (Example: 5 on 4 1/2 would mean 5 bolt holes with 4 1/2" measure to a point halfway between the opposite bolts). |
