What other years of GMC Sierra have the same bolt pattern as the 2025?
The GMC Sierra uses the 6x139.7 pattern from 2024 through 2025. Wheels from any of these model years are dimensionally compatible with the 2025, provided the offset and center bore also match.
What is the center bore of a 2025 GMC Sierra?
The factory center bore (hub bore) for the 2025 GMC Sierra is 78.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Can I use spacers on my 2025 GMC Sierra?
Yes, but ensure the wheel spacers match the 6x139.7 bolt pattern and 78.1mm center bore. Also verify that you have enough thread engagement for your 14x1.5 hardware.
What does 24-31mm offset mean for the 2025 Sierra?
An offset of 24-31mm means the wheel's mounting surface is 24-31mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your GMC.
Why is matching the 78.1mm center bore important for the 2025 Sierra?
The 78.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
