Today, there are many who want to add the "finishing touch" to their trailer
rims. One way to accomplish this, is with a Trailer Wheel Center Cap. In order
to locate the center cap that will match your trailer rim, the center bore of
your wheel must be measured. This measurement will be the size of center cap you
When it comes to the center hole of a trailer rim, it is to some
extent a standardized measurement. For example a 4 lug trailer rim, will
generally have a 2.80 in center bore, where as a 5 lug wheel generally measures
3.19 in or 3.30 in. Getting into the larger sized trailer wheels, a 6 lug
commonly has a measurement of 4.25 in or 4.28 in, and the center bore of an 8
bolt rim is most often either 4.90 in or 5.12 in.
Our center caps are available in chrome-plated steel and plastic, or stainless steel. We even offer black center caps for those tough looking aluminum trailer wheels. Typically, the majority of our caps are compatible with standard axles or axles with E-Z lube, by simply removing a replaceable plug.
