Bolt Pattern Guide – What PCD Means & How to Measure It
Meta Description:
Learn what bolt pattern and PCD mean, how to measure bolt patterns, and how to choose the correct fitment for aftermarket wheels.
Introduction
When purchasing aftermarket wheels, one of the most important specifications is the bolt pattern, also known as PCD (Pitch Circle Diameter).
Choosing the wrong bolt pattern means the wheels simply will not fit your vehicle.
Many drivers ask:
In this guide, we explain everything you need to know about bolt patterns and wheel fitment.
What Is a Bolt Pattern?
A bolt pattern refers to:
Bolt patterns are usually written in this format:
5x114.3
This means:
5 lug holes
114.3 mm circle diameter
What Does PCD Mean?
PCD stands for:
Pitch Circle Diameter
It refers to the diameter of the imaginary circle that passes through the center of the lug holes.
PCD is another term commonly used for bolt pattern.
Common Bolt Patterns
Here are some common bolt patterns used by different vehicles.
| Bolt Pattern | Common Vehicles |
|---|
| 5x112 | Audi, Mercedes-Benz, Volkswagen |
| 5x114.3 | BMW, Ford Mustang, Nissan, Toyota |
| 5x120 | BMW older models |
| 5x130 | Porsche |
| 6x139.7 | Trucks and off-road vehicles |
Always confirm fitment before purchasing wheels.
How to Measure Bolt Pattern
The measurement method depends on the number of lug holes.
4-Lug Wheels
Measure from the center of one hole directly to the center of the opposite hole.
5-Lug Wheels
Measure from the center of one hole to the outer edge of the hole across from it.
This is the most common pattern for aftermarket vehicles.
6-Lug Wheels
Measure center-to-center across opposite holes.
Are Bolt Patterns Universal?
No.
Different vehicles use different bolt patterns, and wheels must match exactly unless adapters are used.
Incorrect bolt patterns will prevent proper installation.
Can You Change Bolt Pattern?
Yes, but usually through:
Wheel adapters
Hub conversion kits
However, these modifications may affect:
Safety
Wheel clearance
Suspension geometry
For best results, use wheels with the correct bolt pattern.
Bolt Pattern vs Wheel Offset
Many people confuse bolt pattern with wheel offset.
They are different specifications.
| Specification | Meaning |
|---|
| Bolt Pattern | Lug hole layout |
| Offset | Wheel mounting position |
Both are essential for proper wheel fitment.
Why Bolt Pattern Matters
Correct bolt pattern ensures:
Incorrect fitment may cause:
Installation failure
Wheel wobbling
Safety issues
Hub Bore & Bolt Pattern
Bolt pattern is only one part of wheel fitment.
You must also check:
Hub bore
Offset
Wheel width
Brake clearance
Complete fitment requires all specifications to match correctly.
