Finding the correct wheel bolt pattern for your car is crucial for ensuring that your wheels fit properly and safely. The bolt pattern, also known as the lug pattern, refers to the arrangement of the bolt holes on your wheel. To determine the correct bolt pattern for your vehicle, you need to know the number of bolt holes and the diameter of the circle they form.
What is a Wheel Bolt Pattern?
A wheel bolt pattern is defined by two numbers: the number of bolt holes and the diameter of the imaginary circle they form. For example, a 5×114.3 bolt pattern means there are five bolt holes, and the circle’s diameter is 114.3 millimeters.
How to Measure Wheel Bolt Pattern?
- Count the Bolt Holes: First, count the number of bolt holes on your wheel. Most vehicles have 4, 5, 6, or 8 bolt holes.
- Measure the Diameter: For an even number of bolt holes, measure the distance from the center of one hole to the center of the opposite hole. For an odd number, measure from the back of one hole to the center of the farthest hole.
Why is the Correct Bolt Pattern Important?
The correct bolt pattern ensures that the wheels fit securely onto your car’s hubs. An incorrect pattern can lead to improper wheel alignment, unsafe driving conditions, and potential damage to your vehicle.

The easiest way to find your car’s bolt pattern is to check the owner’s manual. It typically lists all the specifications, including the bolt pattern.
Look for a Stamp on the Wheel
Many wheels have the bolt pattern stamped on the back of the wheel. Look for a series of numbers, such as 5×120, which indicates the pattern.
Use Online Resources
Websites and databases like Wheel-Size.com allow you to search for your vehicle’s bolt pattern using the make, model, and year of your car.
Consult a Professional
If you’re unsure, consult a professional mechanic or a tire specialist. They have the tools and knowledge to measure the bolt pattern accurately.
