Finding the bolt pattern for your vehicle’s wheels is essential for ensuring compatibility with new wheels or rims. The bolt pattern, also known as the lug pattern, refers to the arrangement of the bolt holes on a wheel. Understanding this pattern is crucial when purchasing new wheels or replacing old ones.
What Is a Bolt Pattern?
The bolt pattern is defined by two numbers: the number of bolt holes and the diameter of the circle they form. For example, a bolt pattern of 5×114.3 means there are five bolt holes and the diameter of the circle they form is 114.3 mm. This pattern ensures that the wheels fit securely on the vehicle’s hub.
How to Measure Your Vehicle’s Bolt Pattern
Step-by-Step Guide
- Count the Bolt Holes: First, count the number of bolt holes on your wheel. This is the first number in the bolt pattern.
- Measure the Diameter: For wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the opposite hole. For wheels with an odd number of bolt holes, measure from the center of one bolt hole to the imaginary circle that passes through the center of the opposite holes.
Tools Needed
- Tape measure or ruler
- Pen and paper for notes
Example
If your vehicle has 4 bolt holes and the measurement across is 100 mm, your bolt pattern is 4×100.
Why Is the Bolt Pattern Important?
The bolt pattern is crucial for the proper fitment of wheels. Using wheels with the wrong bolt pattern can lead to unsafe driving conditions and damage to the vehicle. Always ensure the bolt pattern matches when purchasing new wheels.
Common Bolt Patterns
Here are some common bolt patterns you might encounter:
| Vehicle Type | Common Bolt Patterns |
|---|---|
| Compact Cars | 4×100, 5×100 |
| Mid-Size Cars | 5×114.3, 5×120 |
| SUVs and Trucks | 6×139.7, 8×165.1 |
