What bolt pattern is Chevy Silverado?
The Chevrolet Silverado primarily uses two common wheel bolt patterns depending on the model: 6x139.7 mm for light-duty 1500 models and 8x165.1 mm for heavy-duty 2500HD and 3500HD models.
As the Silverado lineup spans multiple generations and configurations, the exact bolt pattern can vary by year, trim, drivetrain, and whether the truck is a single rear wheel (SRW) or dual rear wheel (DRW) variant. To ensure a correct fit when buying wheels or adapters, always verify the pattern on your specific vehicle via the door jamb placard or the owner's manual.
Light-Duty Silverado 1500
Year range and compatibility
The light-duty Silverado 1500 has commonly used a 6-lug pattern on a 139.7-mm circle (6x139.7 mm, often referred to as 6x5.5 inches) across many generations. This pattern is standard on most 1500 models sold in recent decades, including many 1999–present configurations. Always confirm for your exact year and trim before purchasing wheels.
- 6x139.7 mm bolt pattern (6 on 139.7 mm) — commonly written as 6x5.5 inches
In general, this 6x139.7 mm pattern is the norm for light-duty Silverado 1500s, but there are exceptions among very early or specialty editions. When in doubt, check the door jamb sticker or consult the vehicle’s build sheet.
Heavy-Duty Silverado 2500HD and 3500HD
Year range and compatibility
The heavy-duty Silverado family uses an eight-lug pattern on a 165.1-mm circle (8x165.1 mm, commonly described as 8x6.5 inches). This configuration covers most 2500HD and 3500HD variants, including both SRW and DRW models. Verify for your specific year and configuration, as some aftermarket wheels may require adapters or different hubs.
- 8x165.1 mm bolt pattern (8 on 165.1 mm) — commonly written as 8x6.5 inches
While the 8x165.1 mm pattern is standard for most heavy-duty Silverado trucks, there can be rare exceptions or aftermarket changes. Always confirm with the VIN/build sheet or the dealership if you’re unsure.
Notes on verification and compatibility
Before purchasing wheels or planning a swap, use these steps to confirm the correct bolt pattern for your Silverado:
- Check the driver’s door jamb placard for the bolt pattern specification.
- Consult the owner’s manual or the vehicle’s build sheet.
- Count the lug holes on the wheel or measure the bolt circle diameter with a ruler or caliper if needed.
- Verify whether your truck is SRW or DRW, as some aftermarket parts are sensitive to this distinction.
After confirming the pattern, consider other fit factors such as hub bore size, offset, and brake rotor compatibility. If you plan to use wheels from a different pattern, you may need adapters or a different wheel choice to maintain proper fit and safety.
Summary
In practice, the Chevrolet Silverado uses two primary bolt patterns: 6x139.7 mm for light-duty 1500 models and 8x165.1 mm for heavy-duty 2500HD and 3500HD models. Always verify the exact specification for your specific vehicle year, trim, and configuration by checking the door placard, the owner’s manual, or the build sheet to ensure a correct and safe wheel fit.
