What is the bolt pattern on a Chevy car?
There isn't a single bolt pattern for Chevy vehicles. The bolt pattern depends on the model and year. The most common configurations are 5-lug on 120.65 mm (5x4.75 in) and 6-lug on 139.7 mm (6x5.5 in) for trucks and large SUVs. Always verify the exact specification for your specific Chevy model and year before purchasing wheels.
In more detail, the bolt pattern (also called the bolt circle) describes how many studs a wheel uses and the circle they form on the hub. Because Chevy's lineup ranges from compact cars to full-size trucks and performance models, you’ll encounter several patterns across different generations and trims. This article explains the main categories and how to confirm the right one for your vehicle.
Common bolt-pattern categories
The following overview highlights the main patterns you’re likely to encounter on Chevy vehicles, with guidance on where each tends to appear.
Passenger cars and sports models
Most modern Chevy passenger cars and sports cars use a five-lug pattern. The typical wheel-fit pattern you’ll see is around 120.65 mm (5x4.75 in). This is the standard for many contemporary Chevys, including performance-oriented variants.
- Five-lug patterns around 120.65 mm (5x4.75 in) are widespread among many modern Chevy passenger cars and performance models. This is the most frequently encountered 5-lug pattern in the current lineup.
- Some older or specialty Chevys may use different 5-lug spacings or additional hub considerations; always verify your exact vehicle specification for wheel fitment by checking the owner’s manual or a trusted parts catalog.
Concluding: For most passenger cars and sporty Chevys, expect a 5x120.65 mm bolt pattern, but confirm with your specific model/year before buying wheels.
Trucks and large SUVs
Chevrolet’s trucks and large SUVs typically use a six-lug pattern. The common pattern for many of these vehicles is 139.7 mm (6x5.5 in). This configuration is standard on models like the Silverado family and other full-size GM trucks and SUVs.
- Six-lug patterns around 139.7 mm (6x5.5 in) are typical for Chevrolet trucks and large SUVs, including Silverado, Tahoe, Suburban, and related pickups and full-size SUVs.
- As with any model line, some generations or special editions may vary; always confirm the exact bolt pattern for your vehicle year and trim.
Concluding: If you drive a Chevy truck or large SUV, you are most likely dealing with a 6x139.7 mm bolt pattern, but always verify to avoid compatibility issues when upgrading wheels.
Older or specialty models
Chevrolet’s older platforms or niche models can use other bolt-pattern configurations. These variations exist across different regions and production years, so it’s essential to check the precise spec for your vehicle.
- Older Chevys and some regional variants may employ alternative 5-lug or even unique hub specifications that differ from the current core patterns.
- Always consult the factory service manual, wheel specification sheets, or a dealership parts department to confirm the exact XxY bolt pattern for your model/year.
Concluding: If you’re working with a classic Chevy or a model with a unique configuration, don’t assume — verify the bolt pattern for proper wheel fitment and safety.
How to verify your bolt pattern
To avoid guesswork, use these reliable methods to confirm your Chevy’s bolt pattern before ordering wheels or adapters.
- Check the owner’s manual or the manufacturer’s official wheel-spec sheet for the exact bolt pattern (XxY) and the hub bore size.
- Count the number of lug holes on the wheel (5 or 6 is most common for Chevy) and measure the bolt circle diameter by measuring the distance across the center of opposite lug holes.
- Use a bolt-pattern gauge or consult a dealership, tire shop, or reputable online parts catalog to confirm the specific pattern for your model/year.
- Consider hub bore size and wheel offset/backspacing in addition to the bolt pattern to ensure proper fit and alignment.
Concluding: Once you know the exact XxY pattern, you can select wheels that match, along with appropriate hub bore and offset specs to ensure safe and proper installation.
Summary
Chevrolet vehicles do not share a single bolt pattern. The most common configurations are 5x120.65 mm (5x4.75 in) for many passenger cars and 6x139.7 mm (6x5.5 in) for trucks and large SUVs. Always confirm the exact bolt pattern for your specific model and year, and verify hub bore and offset when planning wheel replacements or upgrades.
