Finding the correct bolt pattern for your car is crucial for ensuring that your wheels fit properly and safely. A bolt pattern refers to the arrangement of the bolt holes on a wheel and is expressed in terms of the number of bolts and the diameter of the circle they form. Here’s how you can determine your car’s bolt pattern.
What is a Bolt Pattern?
A bolt pattern is a description of the number of lug holes in a wheel and the diameter of the circle they form. For example, a 5×114.3 bolt pattern means there are five bolt holes arranged in a circle with a diameter of 114.3 millimeters.
How to Measure Your Car’s Bolt Pattern?
To measure your car’s bolt pattern, you will need a few tools: a ruler or measuring tape, and possibly a caliper for more precise measurements. Follow these steps:
-
Count the Lug Holes: The first step is to count the number of lug holes on your wheel. Common configurations include 4, 5, 6, and 8 lug holes.
-
Measure the Diameter:
- For 4, 6, or 8 lug holes, measure the distance from the center of one lug hole to the center of the opposite lug hole.
- For 5 lug holes, measure from the center of one lug hole to the back of the third lug hole (skip one lug in between).
-
Record the Measurement: Use the measurement to determine the diameter of the circle. This will give you the second part of your bolt pattern.
Why is Knowing Your Bolt Pattern Important?
Understanding your car’s bolt pattern is essential for several reasons:
- Safety: Incorrect bolt patterns can lead to improper wheel installation, affecting your vehicle’s safety.
- Performance: Properly fitting wheels ensure optimal performance and handling.
- Customization: Knowing your bolt pattern helps when selecting aftermarket wheels for customization.

Here are some of the most common bolt patterns you might encounter:
| Bolt Pattern | Vehicles Commonly Using It |

| 6×139.7 | Chevrolet Silverado, Toyota Tacoma |
How to Confirm Your Car’s Bolt Pattern?
- Check the Owner’s Manual: Your vehicle’s owner’s manual often lists the bolt pattern.
- Look for Online Resources: Websites and forums dedicated to car enthusiasts often have databases of bolt patterns.
- Consult a Professional: A mechanic or tire specialist can quickly determine your car’s bolt pattern.
