WHAT IS A BOLT PATTERN?

...and how the heck do I figure out what bolt pattern I have?

First and foremost, 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 wheels. This measurement on the wheel matches the measurement on your wheel studs that are semi-permanently mounted on the hub of your vehicle. Bolt patterns look like, 5x112, 6x139.7 or 4x108— this is a two number system that first tell you have many bolt holes the wheel has, followed by the diameter of the imaginary circle that is around the holes.

Cars typically have smaller bolt holes (4 lug or 5 lug), while trucks typically have more (like 6 lug or 8 lug). However, sometimes a specific vehicle model may have a different bolt pattern depending on the generation. Knowing your bolt pattern will help narrow your search in which wheels are best for your vehicle - but how do you figure out your bolt pattern? There is several ways to do so, either with a special tool or online tools (that we have at the bottom of this page) to help you figure this out.

To start, we'll go through popular bolt patterns and how they're typically measured.

POPULAR BOLT PATTERNS

and how it's typically measured.

4 LUG BOLT PATTERN

Measured in a straight line center to center of two bolt holes sitting directly across from each other. Popular 4 Lug patterns include 4x100 and 4x108.

5 LUG BOLT PATTERN

A difficult pattern to measure accurately without a bolt pattern gauge tool, or a complicated geometric equation. Some popular 5 lug patterns are, 5x100, 5x112, 5x114.3 and 5x127

6 LUG BOLT PATTERN

Measured in a straight line center to center of two bolt holes sitting directly across from each other. Popular bolt patterns include 6x135 and 6x139.7.

8 LUG BOLT PATTERN

Measured in a straight line center to center of two bolt holes sitting directly across from each other.

DUAL LUG BOLT PATTERNS

Note that dual bolt patterns are found exclusively on aftermarket wheels, and are not something a single vehicle will have. Some bolt patterns, such as 5x112 and 5x120 are close enough that some wheel designs can accommodate both bolt patterns. Our Super Touring line is a fantastic example of this. This allows wheel manufacturers to reach a wider range of vehicles with similiar bolt patterns and fitment on a single wheel design.

BOLT PATTERN CONVERSION CHART

Occasionally you may run into a wheel that is measured by inches as opposed to millimeters. Particularly, with off-road capable vehicles, you may see something like 5x5 or 6x5.5. Using our conversion chart below, you can quickly convert between the two just in case you run into something like this.

OK, BUT WHAT IS MY BOLT PATTERN?

We definitely recommend using trusted online tools or work with a wheel and tire specialist to give you the confidence of what your bolt pattern is. Like we said previously, some bolt patterns are within a couple millimeter difference that a slight mismeasurement could give you an inaccurate bolt pattern. Thankfully, the internet is a useful resource and websites such as wheel-size.com exist. Select your specific vehicle below to figure out what bolt pattern your vehicle has.
