# Determining the Bolt Pattern of Your Wheel

## What is the bolt pattern?

The bolt pattern of a wheel tells us the number of lugs (or bolt holes) and the diameter of the circle the lugs sit on. For example, a 5 on 4-1/2" bolt pattern lets us know we need a wheel with 5 lugs that are spaced out evenly on a circle that has a 4-1/2" diameter.

## How do I figure out the bolt pattern?

There are two methods of determining the bolt pattern on a wheel.

### 1. Use the number of lugs and the bolt circle:

• If there is an EVEN number of lugs:
• Measure center-to-center on lugs directly across from each other
• If there is an ODD number of lugs:
• Measure from the center of one lug to a point halfway between the two lugs directly opposite on the bolt circle
• With an odd number of lugs, there is not a lug directly opposite any hole, so finding the circle diameter can be challenging

### 2. Use the distance between the center of one bolt hole to the center of the bolt hole adjacent to it:

• If the distance is:
• 2-5/8" - the bolt pattern is 5 on 4-1/2
• 2-3/4" - the bolt pattern is 5 on 4-3/4
• 3" - the bolt pattern is 5 on 5
• 3-1/4" - the bolt pattern is 5 on 5-1/2
