To measure the center cap of a trailer wheel, you will need some basic tools:
1,Tape measure or ruler: This tool will help you measure the diameter of the center cap.
2,Vernier caliper (optional): If you want more accurate measurements, you can use a caliper to measure the diameter.
Below is a step-by-step procedure for measuring a trailer wheel center cap:
1, Remove the trailer wheel center cap if installed.
2,Measure the trailer wheel center cap outside diameter: Take a tape measure or ruler and place it in the center of the lid.
Measure from edge to edge across the center.
Be sure to measure the widest part of the lid.
This measurement will give you the outside diameter.
3, Measuring the trailer wheel center cap inner diameter: Flip the middle cover up and measure the inner diameter.
This is the diameter of the hole where the center cap mounts to the wheel.
Again, use a tape measure or ruler to measure from edge to edge.
4, Depth measurement (optional): If you want to measure the depth of the center hub cap cover, place it on a flat surface with the open side facing up.
Use a ruler or calipers to measure the distance from the flat surface to the highest point of the lid.
5, Record measurements: Record the measurements trailer wheel center cap you took, including outside diameter, inside diameter, and depth (if measured).
With these measurements, you will be able to determine the correct trailer wheel center cap size when looking for a replacement or ordering a new one.
