Finding out the bolt pattern of your vehicle is crucial for selecting the right wheels. The bolt pattern, also known as the lug pattern, refers to the arrangement of the bolt holes on the wheel hub. It is typically represented by two numbers: the number of bolt holes and the diameter of the circle they form. Understanding your vehicle’s bolt pattern ensures compatibility with aftermarket wheels and is essential for safe driving.
What is a Bolt Pattern?
The bolt pattern of a vehicle is described using two numbers. The first number represents the number of bolt holes on the wheel hub, while the second number indicates the diameter of the circle formed by these holes. For example, a 5×114.3 bolt pattern means there are five bolt holes, and the circle they form has a diameter of 114.3 millimeters.
Why is Knowing the Bolt Pattern Important?
- Wheel Compatibility: Ensures the wheels fit securely on your vehicle.
- Safety: Prevents wheel detachment during driving.
- Aesthetic and Performance: Allows for the selection of wheels that enhance vehicle appearance and handling.
How to Determine the Bolt Pattern of Your Vehicle
Step-by-Step Guide

Measure the Bolt Pattern:
- Tools Needed: Tape measure or ruler.
- Steps:
