What does a PCD such as 5x112 or 5x4.41 mean?

The first number indicates the number of bolt holes (5 bolt holes). The second number indicates the diameter of the imaginary circle through the centre of the bolt holes, expressed in millimetres (112 mm in Europe) or inches (4.41 inch in the US).

How do you measure the PCD on a wheel with 5 bolt holes?

On a 5-bolt wheel you cannot measure directly from centre to centre across. Measure from the rear edge of the first hole to the exact centre of the opposite second hole, or measure from the centre of the hub to the centre of a bolt hole and multiply this number by 2.

Is an American 5x4.75 inch PCD the same as 5x120 mm?

No, 5x4.75 inch is exactly 5x120.65 mm (commonly used by Chevrolet/GM). This differs by 0.65 mm from the European 5x120 mm size (BMW). This small difference can be safely bridged with wobble bolts or specific hub-centric rings.

Bolt Pattern Overview

PCD Overview & Bolt Pattern Conversion Table

In the United States, PCDs are indicated as ‘Bolt Pattern’ in inches, whereas in Europe we use the PCD in millimetres. With this conversion table, you can effortlessly convert American bolt patterns to European millimetres and learn how to measure the PCD of your wheel yourself.

What Is a PCD (Pitch Circle Diameter)?
The PCD of an alloy wheel indicates how many bolt holes the wheel has and the diameter of the imaginary circle that runs through the centre of these holes. A wheel with PCD 5x120 therefore has 5 bolt holes on a circle diameter of 120 millimetres. In America this same pattern is known as 5x4.72 inch. At **Wheels 'N Customs** we check the exact PCD by registration for free with every wheel order!

How Do You Correctly Measure the PCD Yourself?

Measuring a PCD differs depending on the number of bolt holes in the centre of the wheel:

4, 6 or 8 Bolt Holes (Even number): Measure the distance from the exact centre of one bolt hole straight across the hub to the centre of the opposite bolt hole.
5 Bolt Holes (Odd number): You cannot measure directly opposite. Measure from the rear edge of the first bolt hole to the exact centre of the second opposite bolt hole (see diagram).
Formula via the hub: Measure the distance from the centre of the central hub bore to the centre of any bolt hole, and multiply this distance exactly by 2.

In the United States, the ET value is not always expressed in exact millimetres, but often indicated with letters for the Offset category:

American Letter Code	Category Meaning	Corresponding European ET Value (MM)
H	High Offset	ET 35, ET 40, ET 45+ (Front-wheel drive & modern cars)
M	Medium / Normal Offset	ET 20+ (Rear-wheel drive cars & wide rear wheels)
L	Low Offset	ET 0 to ET 15 (Classics, Muscle Cars, 4x4 Off-road)

3. Solutions for Non-Standard PCDs

A. Wobble Bolts & Wobble Nuts (up to 2 mm)

Would you like to fit 5x114.3 wheels on a car with a 5x112 PCD, for example? With our certified **wobble bolts** you can safely bridge a PCD difference of up to 2 mm and it is 100% approved for the APK.

B. PCD Adapter Spacers (from 15 mm)

Do you want to bridge a larger PCD difference (e.g. 5x100 to 5x112 or 5x120 to 5x112)? With special **PCD adapter spacers** you bolt the adapter to your hub and mount the wheel to the adapter.

C. Custom Blank Drilling / Re-drill

Some premium wheel brands (such as Japan Racing, Concaver, Rotiform) can be supplied ‘blank’ (undrilled) from the factory and machined exactly to your specific PCD and ET value.

4. Frequently Asked Questions about PCDs

Is 5x120.7 inch the same as 5x120 mm?

No, 5x120.7 mm (5x4.75 inch) is the classic American PCD for General Motors/Chevrolet. This differs by 0.7 mm from the well-known European 5x120 mm size of BMW. This small difference can be safely bridged with wobble bolts or specific hub-centric rings.

What is the difference between 5x112 and 5x114.3?

5x112 is the standard PCD for European cars (Volkswagen, Audi, Seat, Skoda, Mercedes-Benz and newer BMWs). 5x114.3 (5x4.5 inch) is the global standard for Japanese and Korean brands (Toyota, Nissan, Mazda, Lexus, Honda, Hyundai, Kia). These two sizes can be fitted interchangeably with the help of wobble bolts!

Why is the hub diameter just as important as the PCD?

Even if the PCD (bolt holes) matches exactly, the central opening in the wheel (hub bore / Center Bore) must fit the car’s axle. Is the wheel’s hub bore larger? Then you need hub-centric rings to prevent vibrations at speeds of 90 to 130 km/h.
