What is a Bolt Pattern? | Explained
A bolt pattern is the specification that determines which wheels are compatible with your vehicle. Understanding it saves you from buying the wrong wheels.
The Two Numbers
Every bolt pattern is written as two numbers separated by an x. For example: 5x114.3
- 5 is the number of lug holes (bolts) on the wheel
- 114.3 is the PCD (Pitch Circle Diameter) in millimeters, which is the diameter of the imaginary circle that passes through the center of each lug hole
PCD Explained
The PCD is the critical measurement. Even if two wheels both have 5 lugs, if one has a 114.3mm PCD and the other has 120mm, they are not interchangeable. The bolt holes will not line up with the hub.
Does Bolt Pattern Guarantee Fitment?
No. Bolt pattern is the most important factor but not the only one. You also need to match:
- Center bore: the diameter of the center hole. Can be resolved with hub rings.
- Offset (ET): how far the wheel sits in or out from the hub face
- Width and diameter: must fit within the wheel well and clear brakes
Cross-Compatible Patterns
Some bolt patterns appear across many brands, which makes wheel swaps possible. The most common cross-compatible pattern is 5x114.3, shared by Ford, Honda, Nissan, Hyundai, Kia, Toyota, and many others.
