Chevrolet vehicles come with a wide variety of bolt patterns. For example, the Chevy lug pattern on a 2009 2500 truck is different from that of a 2010 Impala. It’s critical to get the measurements correct.
The bolt pattern for a 2009 Chevy 2500 is 8x6.5.
Here’s a formula that describes what that bolt pattern actually means:
# of bolts x diameter of the circle they form
The first number in your bolt pattern is 8. That means that each wheel on your truck has eight lugs. The second number, 6.5, is the diameter of the circle these lugs form as measured in inches.
There are a few other stats that matter when it comes to your Chevy’s wheels. You’ll need to know your wheel size, stud size, center bore, and torque specifications. These should be listed in your owner’s manual but we’ve also listed them here for your convenience:
Wheel tightening torque: 190 Nm
If you’ve made any other modifications since you originally bought the vehicle, make sure you update these stats to reflect those changes.

How to measure your Chevy 2500’s bolt pattern
To confirm the pattern for yourself, grab a measuring tape or a ruler. Head out to your truck and pick a wheel, any wheel. If only this were a game show with prizes!
Your truck has an even number of lug holes, so it’s easy to calculate the diameter. Pick a lug hole and measure from this hole across to the bolt hole that is directly opposite.
Your measurement should be 6.5 inches. In combination with the number of bolts (8), you can see that your bolt pattern is 8 bolts by 6.5 inches in diameter, or 8x6.5.
