What bolt pattern does Chevy use?
Chevrolet uses more than one wheel bolt pattern, depending on the model and year. The two most common modern patterns are 5x120.65 mm (5x4.75 inches) for most cars and 6x139.7 mm (6x5.5 inches) for trucks and large SUVs.
Patterns by vehicle type
The following patterns cover the main split you’ll see across today’s Chevrolet lineup. This helps explain why wheels aren’t universally interchangeable across all Chevrolets.
- 5x120.65 mm (5x4.75 inches) — A widespread pattern for many Chevrolet passenger cars and sports models, including popular variants like the Camaro and Corvette, as well as several mid-size sedans and crossovers in recent years.
- 6x139.7 mm (6x5.5 inches) — The standard pattern for Chevrolet’s full-size trucks and larger SUVs, such as the Silverado/Sierra pickups and the Tahoe/Suburban family.
These two patterns represent the primary divergence in the current Chevrolet lineup: smaller, lighter vehicles generally use the 5-lug 120.65 mm pattern, while heavy-duty and larger models use the 6-lug 139.7 mm pattern. There are exceptions by model year and market, so always verify for your specific vehicle.
How to verify your exact bolt pattern
To determine your exact bolt pattern and avoid misfits, use a combination of official specs, VIN-based lookups, and hands-on measurement. Here are practical steps you can take.
- Check the owner’s manual or the official Chevrolet service/parts catalog for your vehicle’s wheel specifications by year and trim.
- Look at the door placard or a sticker near the driver’s door jamb; it sometimes lists wheel and lug information, and you can cross-check the bolt pattern there.
- Count the number of lug holes on the wheel hub (five or six is the typical maximum you’ll encounter on modern Chevrolets).
- Measure the bolt circle diameter (BCD or lug circle): measure from the center of one lug hole to the center of the opposite lug hole across the hub to get the pattern diameter (e.g., 120.65 mm or 139.7 mm).
- Measure the center bore diameter to ensure hub-centric compatibility or note if spacers or rings are needed.
- When in doubt, use reputable online databases (such as manufacturer specs or wheel-fitment resources) or consult a Chevrolet dealer to confirm the exact pattern for your VIN.
Accurate verification helps ensure proper fitment, safe installation, and correct hub alignment. If you’re swapping wheels, also consider offset, width, and hub-centric vs. lug-centric designs in addition to the bolt pattern.
Regional and year-specific variations
While the patterns above cover the core differences in recent U.S.-market Chevrolets, regional models and older generations may use alternative patterns. Always confirm for the exact year and model you own or intend to modify.
Summary
Chevrolet does not rely on a single bolt pattern across its entire lineup. The most common modern configurations are 5x120.65 mm for many passenger cars and 6x139.7 mm for trucks and larger SUVs. Always verify the bolt pattern for your specific year, model, and trim via official manuals, VIN-based lookups, or trusted wheel-fitment databases before purchasing wheels or adapters. Understanding the pattern, plus center bore and offset, helps ensure safe, proper wheel compatibility.
