Many GMC vehicles have a 6x5.5 or 6x4.72, but you’ll need to know the exact measurements of your GMC’s wheels if you plan on switching out the rims for a new set.
It might not be a common occurrence for most GMC owners, but a damaged rim can just as easily come from city driving as it can from off-roading—in which case you’ll need to know your vehicle’s lug pattern if you ever need to replace a wheel.

Why you should know your GMC’s lug pattern

When we refer to a vehicle’s lug—or bolt—pattern, we’re talking about the number and spacing of lug holes on your GMC’s wheels. This pattern is made up of two numbers: the first being the number of lug holes, while the second indicates the diameter of the imaginary circle formed by those bolt holes.
In practice, this means a wheel with a 5x5 lug pattern will have 5 evenly-spaced bolts arranged in a 5-inch circle.
If you ever need to switch out your wheels due to damage or normal wear and tear—or just because you feel like it—you’ll need to know your GMC’s lug pattern before doing so.

The basics of lug pattern terminology

Making sense of that table may seem incredibly daunting if you’ve never dealt with GMC rims before. But, in reality, those numbers are fairly simple to understand—once you become familiar with a few key terms.
Lug pattern: Sometimes called a bolt pattern, this figure shows the number of lug holes and the diameter of the circle they form. Knowing this pattern will make finding a wheel that fits your GMC much easier.
OEM wheel size: This simply refers to the diameter of your GMC’s original wheels, as OEM stands for “Original Equipment Manufacturer.” You’ll need to know this measurement should you ever need—or want—to install new rims.
Offset: A wheel’s offset refers to the distance from the mounting surface to the center of the rim. If the offset is positive, it means the wheels are being pulled in towards the car, whereas a negative offset means the wheels will stick out. Most GMC vehicles have a…
Stud size: Generally speaking, stud sizes are written in two different ways. In the U.S., fasteners are expressed as stud diameter x threads per inch(e.g. 1/2x18), while fasteners in countries using the metric system are written as stud diameter x distance between threads (e.g. 15mm x 1.50).
Center bore: Your wheel’s center bore is the opening that centers it on the wheel hub. This hole often varies in size, so it’s important to know the exact measurement.

How to measure your GMC’s lug pattern

Of course, you may own a GMC not included in the table above. In this case, you’ll need to measure the lug pattern yourself—you can achieve this with either a ruler or measuring tape.
You’ll first want to count the number of lugs—most GMCs will have six, but some have five or even eight. Then you’ll need to find the diameter of the bolt pattern.
Place the end of your ruler or measuring tape along the outer edge of any lug hole and measure directly across the circle so it lines up with the opposite hole. Of course, if your GMC only has five, you’ll end up between holes, in which case you’ll need to measure to the center of the nearest hole. Now you have the diameter!
In practice, this would mean that if you counted six bolt holes and came up with a diameter of 5.5 inches, your GMC’s lug pattern would be 6x5.5.

FAQs

No, GMC and Ford don’t have the same bolt pattern, which means you won’t be able to swap wheels across the two makes.
No! A 4x4 bolt pattern isn’t the same as a 4x114.3mm metric lug pattern, but it is the same as a 4x4.5 inch lug pattern. The proper conversion for a 4x4 pattern would be 4x127mm.
