What bolt pattern is a 2024 GMC 2500?

The 2024 GMC Sierra 2500 Heavy Duty uses an 8-lug bolt pattern on a 170 mm bolt circle. In practical terms, that means eight evenly spaced lug holes on a circle that measures 170 millimeters in diameter (about 6.69 inches).

Understanding this spec is essential for wheel purchases and upgrades: it determines whether aftermarket rims will mount correctly and safely on a Sierra 2500. The specification is standard across the 2024 Sierra 2500 lineup, but buyers should verify the exact configuration for their vehicle, especially if swapping wheels from a different trim or a prior year.

Bolt Pattern Basics for the 2024 GMC Sierra 2500

Below is a concise breakdown of what the 8x170 mm bolt pattern means for wheel compatibility and basic specs to check when shopping for replacements.

• Pattern: 8 lug holes


• Bolt circle diameter: 170 mm (approximately 6.69 inches)


• Number of studs: 8


• Common application: Sierra 2500 HD family; verify with your exact build if you have a special edition or aftermarket wheels

In addition to the bolt pattern, be mindful of the hub bore size and wheel offset to ensure proper fitment and center alignment.

Practical Guidance for Wheel Shopping

Before selecting wheels or tires, this overview helps ensure you buy components that fit safely and perform as expected on your GMC Sierra 2500.

• Confirm the wheel is designed for 8x170 mm bolt pattern


• Check hub bore compatibility to fit the GMC hub without spacers


• Verify offset and backspacing to avoid clearance issues with brakes and suspension


• When in doubt, consult the owner's manual or a trusted retailer for VIN-specific specs

Proper matching of bolt pattern, hub bore, and offset reduces the risk of installation problems or run-out vibrations.
