How To Measure Your Center Cap for Custom Wheels

Hold the center cap so that the opening is facing downward in your hand. Place a tape measure inside the center cap until you hit the face of the center cap, on the inside of the cap.

Mark the measurement on a piece of paper with a pen, as “Depth.”
