2005 Chevy 2500 bolt pattern
The bolt pattern for your 2005 Chevy 2500 is 8x6.5. And unless you have bolt pattern experience or some rock-solid tire intuition, that may not mean anything to you yet. Each bolt pattern, or lug pattern, gives two numbers arranged as such:
# of bolts per wheel x diameter of the circle they form
So the 8x6.5 bolt pattern of the 2005 Chevy 2500 shows that there will be 8 bolts on each wheel, and those 8 bolts will form a circle that is 6.5 inches in diameter. Knowing the bolt pattern is a good start to swapping your tires, but you’ll need some other information too, including the factory wheel size, stud size, wheel offset, center bore measurement, and torque specs:
- Factory wheel size: 16 inches
- Stud size: M14x1.5 (14 mm stud thread, 1.5 mm thread spacing)
- Offset: 12 to 20 mm (depending on trim level)
- Center bore: 116.6 mm
- Wheel tightening torque: 190 Nm
How to measure your Chevy 2500’s bolt pattern
All the information above should be enough to start shopping for and swapping out your wheels for your shiny new set, but it may be helpful to learn to measure your vehicle’s bolt pattern yourself. Happily, the process is pretty straightforward.
Grab some kind of measuring tool, like a measuring tape or even a ruler. Go out to any of your Chevy’s current tires and start measuring from the center of any bolt to the center of the bolt directly opposite it. With an even number of bolts, there will be a true opposite, so make sure you take your measuring tape to the right lug.
Whatever number you come up with is the circle’s diameter, so you’ll just need to put the number of bolts before it to get your Chevy’s bolt pattern.
