What is a Bolt Pattern?

A bolt pattern refers to the orientation and alignment of the bolts for a wheel. It refers to the number and the spacing of the required bolts for the rim to attach to the vehicle. This is also known as a lug pattern.

Bolt patterns cannot be changed without an adapter. The bolt pattern that comes with a car is standard to that vehicle.

The first number in a bolt pattern refers to the number of bolts. This value is usually 4, 5, 6, or 8.

The second number in a bolt pattern refers to the diameter of the lug circle. See the next section for examples on how to measure the diameter.

How to Measure Bolt Pattern?

Bolt pattern is measured by first counting the number of lugs on the wheel then measuring the diameter.

This diameter can be measured and presented in either inches or mm.

The diameter is measured by an imaginary circle that goes through the center of all the bolts. An example for a 4 bolt and 5 bolt pattern is shown below.

The diameter can be measured from the center point of one bolt to the center point of one across it. But an odd bolt pattern diameter is measured with an imaginary circle through the center of all the bolts.

Why is the Bolt Pattern Important?

You need to know the bolt pattern of your vehicle or truck in order to select the appropriate rims for your car. The bolts are what attach the rim and therefore the wheel/tire to your car. To install a rim to the car, the bolts must align with those of the vehicle.

If you have a rim that doesn’t match the exact bolt pattern of your vehicle, you may be able to use an adapter that can convert one bolt pattern to another.

These adapters, however, do also act as spacers. This means that your wheels will stick out more out of the side of your truck making your wheel track wider.

This is usually only done for cosmetic reasons. If using an adapter, you should not plan to use the car for towing or hauling. They tend to decrease the capabilities of the truck and usually cannot stand the high impact and power required to carry these loads.

Below are some common adapters for your Sierra if you are looking to use a rim pattern different than the standard.
