What is a bolt pattern?
…and how the heck do I figure out what bolt pattern I have?
A bolt pattern—also known as a lug pattern—is the measurement of an imaginary circle formed by the lug holes at the center of a wheel. This measurement matches the wheel studs mounted on the hub of your vehicle. Bolt patterns such as 5x112, 6x139.7, or 4x108 use two numbers: the first tells you how many bolt holes the wheel has, and the second gives the diameter of the imaginary circle around those holes.
Cars typically use four- or five-lug patterns, while trucks commonly use six- or eight-lug patterns. A specific vehicle model can also use different patterns across generations. Knowing the correct pattern helps narrow your wheel search—but how do you determine yours? You can use a bolt-pattern gauge, consult a trusted online tool, or work with a wheel and tire specialist.
We’ll start with popular bolt patterns and how they’re typically measured.
Popular bolt patterns
How they’re typically measured.
4-lug bolt pattern
Measure in a straight line from the center of one bolt hole to the center of the hole directly opposite it. Popular four-lug patterns include 4x100 and 4x108.
5-lug bolt pattern
Five-lug patterns are difficult to measure accurately without a bolt-pattern gauge or a geometric calculation. Common patterns include 5x100, 5x112, 5x114.3, and 5x127.
6-lug bolt pattern
Measure in a straight line from the center of one bolt hole to the center of the hole directly opposite it. Popular patterns include 6x135 and 6x139.7.
8-lug bolt pattern
Measure in a straight line from the center of one bolt hole to the center of the hole directly opposite it.
Dual-lug bolt patterns
Dual bolt patterns are found exclusively on aftermarket wheels; a single vehicle does not have two bolt patterns. Some patterns, such as 5x112 and 5x120, are close enough that certain wheel designs can accommodate both.
Our Super Touring line is a great example. This approach allows wheel manufacturers to support a wider range of vehicles with similar patterns and fitment using a single wheel design.
Bolt pattern conversion chart
Some wheels—particularly those for off-road vehicles—list bolt patterns in inches instead of millimeters. Use these tables to quickly compare the two formats.

What is my bolt pattern?
Use a trusted online tool or work with a wheel and tire specialist to confirm your bolt pattern. Some patterns differ by only a few millimeters, so a small measuring error can produce the wrong result.
