What is the bolt pattern on a 2012 Chevy Avalanche?
The 2012 Chevy Avalanche uses a 6-lug wheel pattern on a 139.7 mm bolt circle (6x139.7), with a center bore of about 78.1 mm (3.07 inches).
This pattern is standard for GM full-size trucks of that era, including the Silverado/Sierra family and related models. Knowing the bolt pattern helps when selecting wheels, adapters, or winter setups, and it should be checked alongside hub size and brake clearance for proper fitment.
Bolt pattern details
For quick reference when shopping for wheels or adapters, here are the core specs you need to know.
- Bolt pattern: 6x139.7 mm (6 on 5.5 inches)
- Center bore: 78.1 mm (3.07 inches)
These two measurements determine whether a wheel will mount on the Avalanche’s hub and align with the brake system. Other factors like offset and wheel diameter also affect fitment and performance.
Practical considerations for wheels and tires
When shopping, consider the following to avoid fitment issues.
- Wheel offset and width — ensure adequate clearance with suspension components and brakes
- Hub-centric vs lug-centric wheels — proper centering reduces vibration
- Brake caliper and rotor dimensions — verify no interference with the wheel barrel or spokes
- Intended use — factory OEM wheels vs aftermarket options may have different specs
Always verify specifications with the wheel manufacturer and, if possible, consult a professional installer. Mismatched bolt patterns or centering can lead to safety risks on the road.
Summary
The 2012 Chevy Avalanche uses a 6x139.7 mm bolt pattern with a 78.1 mm center bore, a setup shared with many GM full-size trucks of the era. When choosing wheels, confirm offset, hub centering, and brake clearance in addition to the bolt pattern to ensure proper fitment and safe operation.
