The 2014 GMC Sierra 1500’s bolt pattern is 6x5.5 or 6 on 5.5. Each wheel on a 2014 Sierra 1500 has 6 bolts—also called lugs—and if you were to draw a circle that perfectly intersects each lug, that circle would have a diameter of 5.5 inches.
Before you can put some fresh wheels on your 2014 Sierra 1500, you’ll need to double-check some specs—like the bolt pattern on your specific GMC Sierra! In this article, we’re covering how to read bolt patterns and measure them for yourself, so you can find the right size of new wheels to impress your friends!

Every configuration of the 2014 GMC Sierra 1500 has a 6x5.5 bolt pattern or 6 on 5.5. Also referred to as a lug pattern, here’s what these numbers mean:
# of bolts x diameter of the circle they form
In other words, every wheel on the GMC Sierra 1500 is secured with six lugs that form a circle with a 5.5-inch diameter. The 2014 Sierra 1500 bolt pattern does not apply to 2500 and 3500 models from this year, which come with eight lugs instead of six. Be sure to check bolt patterns for these larger trucks in their owner’s manual or by measuring them yourself.
It’s important to know your truck’s bolt pattern if you plan on replacing the rims, but that’s not the only thing you should be aware of. To get the right set of wheels installed the right way, you’ll need a few more specs, such as stud size, wheel offset, center bore measurement, and torque specifications. 
Here are the figures you need for a 2014 Sierra 1500:
  • Factory wheel size: 17”, 18”, or 20”
  • Stud size: M14 x 1.5 mm
  • Offset: 20 to 40 mm
  • Center bore: 78.1 mm
  • Wheel tightening torque: 190 Nm

How to measure your GMC Sierra’s bolt pattern

Bolt patterns are fun! And you can easily figure them out on your own. All you need to measure any wheel’s bolt pattern is a measuring tape or a ruler.
Just measure the distance from the center of one lug to the center of the one across from it. This measurement is the diameter of the circle that the lugs form, which you can plug into the bolt pattern formula as the second figure (in this case, 5.5 inches).
Then just count the lugs on the wheel to get the first number. Congrats—you saved yourself the trouble of pulling out your phone and asking the internet for help!
However, if you come across a wheel that has an odd number of lugs, you’ll have to measure the diameter from the outer edge of one bolt to the center of one of the opposite ones. This is to account for the fact that no two bolts are the full diameter apart from each other (directly across) on a wheel with an odd number of bolts.
was easy to use, and they saved me a lot of money on my truck. I would definitely recommend them.” —Johannes T.
