A dual-drilled wheel has two sets of bolt holes, so it can fit two different bolt patterns. For example, a dual-drilled wheel might have both 4x156 and 4x137 patterns. On these wheels, the larger hub bore from the two patterns is used to ensure the wheel fits correctly.
HOW TO MEASURE A BOLT PATTERN?
The bolt pattern, sometimes called the lug pattern or PCD (Pitch Circle Diameter), measures an imaginary circle made by the lug holes at the center of your UTV wheel. The first number tells you how many bolt holes the wheel has. The second number is the diameter of the circle around those holes. For example, a 4x156 wheel bolt pattern (or 4/156) means there are 4 lug holes evenly spaced around a 156mm circle.
Usually, larger vehicles have more lugs, such as heavy-duty trucks with 8-lug bolt patterns. Smaller vehicles have fewer. It's always smart to know your bolt pattern, no matter what make or model you choose.
What is your wheel bolt pattern?
There are a few key numbers to burn into your head when it comes to powersports, and your bolt pattern (PCD) should be one of them. You never know what situation you or a member of your riding group may get into, and having the right spare wheel/tire combo could make the difference between a fun day and a very long one. Tire plugs are an excellent solution for minor cuts and punctures; however, depending on the terrain, you may want to get a spare wheel/tire to cover your bases. Ensuring that your spare fits your vehicle or your buddy's machine is crucial. Check out our fitment guide here.
Learn how to mount your wheels properly.
Never try to install wheels on your vehicle that don't match your OE bolt pattern. The wrong bolt pattern can prevent the wheel from mounting safely. You should have no resistance when installing your wheels on the vehicle's studs. If you have ANY resistance, remove the wheel and double-check that you have the correct bolt pattern. All wheel manufacturers engineer wheels with a small amount of play in the bolt hole to prevent the stud from stripping during installation. Correct wheel installation is incredibly important for ensuring your wheels are safe.
