What Size Center Cap Do I Need?

In my daily work, the questions I get asked most often are: “Can my aftermarket wheels fit the original factory wheel center rim caps?” or “I bought a set of used wheels, but the center caps are missing—how do I replace them?”
Today, I've compiled this ultimate guide—How to measure wheel center caps — based on real-world issues encountered by fellow car enthusiasts and my professional expertise. In just three steps, you can find the perfect crown for your beloved wheels.

Step 1: Precise Measurement - The Foundation of Everything

When selecting the aftermarket wheel center cap, even the slightest error can prevent installation. Therefore, the first and most critical step is precise measurement.
Prepare a digital caliper.
Why must it be a digital caliper? Because the size of the wheel center bore is measured in diameter, the naked eye or a standard tape measure simply cannot achieve millimeter-level precision. A digital caliper effortlessly provides the most accurate millimeter reading, eliminating all guesswork.

Step 2: Identify Your Cap Type & Measure

First, ensure the wheel and center bore are clean and dry. Then, identify which type of center cap you have and take the following measurements:

For Snap-On Wheel Center Cap

A. Outer Diameter: The dimension at the widest point on the front face of the center wheel cap.
B. Clip total length: The distance between the two symmetrical clips on the center cap.
C. Clip installation length: Distance from the lowest point to the highest point of the clamp

Snap Center Cap

For Push Through Center Cap

A. Outer diameter of the barrel: Measure at the outermost circumference of the cylinder.
B. Inner height: Distance from the back of the wheel hub cover to the base plane
