What size is the bolt pattern on a Chevy 6?
The term “Chevy 6” most often refers to a six-lug wheel pattern used on many Chevrolet trucks and large SUVs. The typical size is 6x139.7 mm (6 on 5.5 inches), but the exact bolt pattern can vary by model and year. Always verify for your specific vehicle.
Interpreting the 6-bolt reference and where it applies
In wheel terminology, a bolt pattern refers to the arrangement of lug holes on the wheel hub. A “6-bolt” setup means there are six lug holes. For Chevrolet’s modern full-size trucks and many large SUVs, the standard is 6x139.7 mm (which is 6 on 5.5 inches). This pattern is common across several models, but there are exceptions depending on the exact vehicle and generation. If you’re shopping wheels or replacements, confirm the pattern on your vehicle’s data placard or owner’s manual before proceeding.
Common vehicles that use the 6x139.7 mm pattern
Chevrolet’s six-lug pattern is most commonly found on their larger, truck-based platforms. The following representative models (and their GM counterparts) typically use this bolt pattern in modern forms:
- Chevrolet Silverado 1500 and Silverado HD
- Chevrolet Tahoe and Suburban
- Chevrolet Avalanche (where applicable in generations that continued production)
- GM-branded equivalents like GMC Sierra and GMC Yukon also use the same pattern
Because patterns can vary with generation and trim, always double-check the exact specification for your year and model. The vehicle’s door placard (often on the driver’s door jamb) or the owner's manual will list the correct bolt pattern and lug count.
How to verify your exact bolt pattern
To avoid mismatched wheels or adapters, confirm your vehicle’s bolt pattern with these steps:
- Check the owner’s manual or the placard on the driver’s door jamb for wheel specs, including bolt pattern and lug count.
- Count the number of lug holes on the wheel hub if you’re looking at a wheel you already own; six lugs indicate a 6-bolt pattern.
- Measure the bolt circle diameter (BCD) by measuring from the center of one lug hole to the center of the opposite lug hole across the hub. For 6x pattern, you’re typically looking for a 139.7 mm diameter.
- Cross-check with reputable sources (manufacturer sites, vehicle data catalogs, or a dealer) using your exact year, make, and model.
- If in doubt, bring your vehicle information or a wheel you know is correct to a tire shop or dealer to confirm compatibility.
Following these steps will help you determine whether your Chevy uses the standard 6x139.7 mm bolt pattern or a different arrangement so you can source the right wheels or adapters.
Summary
For most modern Chevrolet trucks and large SUVs, a 6-bolt configuration uses a bolt pattern of 6x139.7 mm (6 on 5.5 inches). However, bolt patterns can differ by model year and generation, especially for non-truck Chevy models. Always verify against the vehicle’s placard or owner’s manual to ensure a proper fitment before purchasing wheels or adapters.
Are Ford and Chevy 6-lug the same?
No, Ford and Chevy 6-lug patterns are not always the same, as different models use different bolt patterns, such as the Ford F-150's 6x135mm6 x 135 m m6𝑥135𝑚𝑚 pattern and the Chevy Silverado's 6x139.7mm6 x 139.7 m m6𝑥139.7𝑚𝑚 pattern. However, some specific Ford and Chevy models share a common bolt pattern like 6x139.7mm6 x 139.7 m m6𝑥139.7𝑚𝑚, and for those vehicles, wheels can be interchangeable, though issues may arise with the center bore or wheel offset.
Common bolt patterns
- Ford F-150: Uses a 6x135mm6 x 135 m m6𝑥135𝑚𝑚 bolt pattern.
- Chevy Silverado: Uses a 6x139.7mm6 x 139.7 m m6𝑥139.7𝑚𝑚 bolt pattern.
- Ford Ranger: Can share a 6x139.7mm6 x 139.7 m m6𝑥139.7𝑚𝑚 bolt pattern with some Chevy models.
Potential issues and solutions
- Center Bore: Even if the bolt pattern is the same, the hole in the center of the wheel (center bore) may be a different size. For example, some Ford vehicles have a larger center bore than Chevy vehicles.
- Wheel Offset: The offset can also be different, which affects how the wheel sits in relation to the vehicle's suspension.
- Solution: If the center bore is different, you may need a hub-centric ring or a wheel adapter to ensure a proper fit and prevent vibration.
Important considerations
- Measure first: Always confirm the specific lug pattern for your vehicle's year, make, and model before purchasing new wheels.
- Check with a professional: When in doubt, it is best to consult with a service team or a wheel specialist to ensure a correct fit and safe installation.
