What is stock Chevy lug pattern?
Most Chevrolet vehicles use one of two common bolt patterns. For the majority of modern Chevrolets, the stock lug pattern is either a 5-lug, 4.75-inch (5x120.65 mm) bolt circle or a 6-lug, 5.5-inch (6x139.7 mm) bolt circle. There are exceptions by model and year, so always verify your exact vehicle’s specification.
In more detail, the lug pattern (also called the bolt circle) is defined by two factors: how many lug holes the wheel has and the distance across the circle that passes through opposite lug holes. Chevrolet generally sticks to two standard configurations today: a 5-on-4.75-inch pattern for most passenger cars and crossovers, and a 6-on-5.5-inch pattern for trucks and larger SUVs. Some older or specialty models do not follow these two patterns, so it’s essential to check the exact specification for your specific year, trim, and drivetrain.
Common lug patterns by vehicle type
The two patterns below cover the vast majority of current Chevrolet vehicles. This helps you quickly identify which wheels or adapters will fit your ride. If your model year falls outside these norms, consult the official GM parts catalog or your owner’s manual for the precise bolt circle.
- 5x120.65 mm (5 on 4.75 inches) — used on most modern passenger cars and crossovers, including popular models like the Camaro, Corvette, Malibu, Equinox, and Cruze.
- 6x139.7 mm (6 on 5.5 inches) — used on Chevrolet trucks and many full-size SUVs, such as the Silverado 1500, Tahoe, and Suburban families.
In practice, these two patterns cover the majority of current Chevrolet lineup. Always verify for your exact model and year, especially if you’re shopping for wheels, tires, or adapters.
How to verify your exact lug pattern
To ensure you get wheels that fit correctly, confirm the exact bolt pattern for your vehicle using reliable sources and simple measurements.
- Check the owner’s manual or the official GM parts catalog for your model/year to confirm the bolt pattern and hub bore.
- If you don’t have the manual handy, look up your vehicle by VIN on GM’s or a reputable parts retailer’s site; the bolt pattern is listed in the wheel/titting specs.
- Measure the bolt pattern directly: count the number of lug holes on the wheel and, using a caliper or a measuring tape, measure the distance between opposite lug holes (the bolt circle diameter).
- Consider hub bore and lug nut/thread details: even with the same bolt pattern, hub bore size and thread pitch matter for proper fitment and centering.
Verifying these details helps prevent wheel fitment issues, including clearance, centering, and safe lug engagement.
Summary
For today’s Chevrolet lineup, the two primary stock bolt patterns are 5x120.65 mm (5 on 4.75 inches) for most cars and crossovers and 6x139.7 mm (6 on 5.5 inches) for trucks and large SUVs. There are exceptions by model and year, so always check the exact specification for your vehicle. When in doubt, consult the owner’s manual or an official GM parts resource, and verify with precise measurements before purchasing wheels or adapters.
