What is a bolt pattern?

Your vehicle's bolt pattern is one of, if not the, first criteria that needs to be considered when determining if a wheel will fit your car or not. The bolt pattern is the number and spacing of the lug hole openings which will match the vehicle hub’s corresponding stud or bolt pattern measurement.

How do you know if your new wheels are going to fit you specific make/model of UTV or ATV? By memorizing the handful of bolt patterns that fit all makes/models.

Unlike the automotive industry, we are lucky to only have a small handful of bolt patterns we need to memorize. It's good practice to know what your specific make/model's bolt pattern is in the event you need a spare, need to replace parts or are communicating with help if you're in a pinch. Before we jump into what bolt patterns are out in the wild, let's get a quick 101 on why bolt patterns exist and what makes each of them unique. 

Your vehicle's bolt pattern is one of, if not the, first criteria that needs to be considered when determining if a wheel will fit your car or not. The bolt pattern is the number and spacing of the lug hole openings which will match the vehicle hub’s corresponding stud or bolt pattern measurement.

Imagine a circle that intersects each stud or bolt hole. The number of holes and the diameter of that circle (sometimes expressed in inches, sometimes in millimeters) combine to form the bolt pattern. Measuring a bolt pattern can be somewhat straight forward for a 4 lug wheel, as you can measure from the center of one opening straight across to the other. However, odd number patterns like the Polaris RZR Pro R five bolt pattern add another step.

Most Common

Polaris: All modern and full sized ATVs and UTVs are 4x156 with the exception of the Turbo R and Pro R which are 5x4.5

Can-Am: All modern and full sized ATVs and UTVs are 4x137

Honda: All non-sport ATVs and UTVs are 4x110 with the exception of the Pioneer 1000 and Talon which are 4x137 bolt pattern.

Kawasaki: ATV's with a Solid Rear Axle (SRA) use 4x137 bolt pattern. KRX 1000 uses a 4x156 bolt pattern. ATV's with Independent Rear Suspension use 4x110 bolt pattern. Mule and Teryx's use a 4x137 bolt pattern with a 12mm stud. Mule PRO-FXT's use a 4x156 bolt pattern. 

Yamaha: All non-sport and modern ATVs & UTVs use a 4x110 bolt pattern, with the exception of the 2019+ YXZ, which uses a 4x156 bolt pattern.

How to Measure

On even bolt patterns (4-lug), measure from the center of one bolt hole to the center of the bolt hole directly across from it. On odd numbered bolt patterns (5-lug), measure from the very top of one bolt hole to the center of the bolt hole directly across from it.

A couple of the most common bolt patterns are 4x156 (which means four lugs and a distance of 156mm between each) and 4x137 (four lugs and 137mm between lug holes).

Note: You may see bolt pattern shown in several different ways. If you see Pitch Circle Diameter (PCD) or Bolt Circle, know it is simply referencing your bolt pattern above.
