What is the Chevy 1500 bolt pattern?
The Chevy 1500’s wheel bolt pattern is 6 lug holes on a 139.7 mm bolt circle (6x139.7 mm, commonly written as 6x5.5 inches).
For the Silverado 1500 and related GM trucks, this pattern is the standard across most years and trims, and it is shared with many GM SUVs like the Tahoe, Suburban, and Yukon. Always verify your exact year and trim, as rare factory options or aftermarket modifications can affect fitment or hub requirements.
Understanding bolt patterns and fitment
Bolt pattern refers to the number of lug holes and the diameter of the circle that passes through the centers of those holes. The right pattern must match between wheel and hub, but you also need to consider hub bore size and wheel offset to ensure proper alignment and clearance with brakes and suspension.
Chevy 1500 bolt pattern specifics
Before listing the core facts, here are the essential points you should know about the Silverado 1500's bolt pattern.
- Pattern: 6 lug holes on a 139.7 mm bolt circle (6x139.7 mm), commonly referred to as 6x5.5 inches.
- Vehicles sharing this pattern: Silverado 1500, GMC Sierra 1500, and many GM full-size trucks and SUVs such as the Tahoe, Suburban, and Yukon family share the same basic lug count and spacing.
- Hub bore: typically around 78.1 mm (3.07 inches); check your specific year/model since some trims or aftermarket wheels may require center rings.
- Wheel compatibility: most OEM wheels and a wide range of aftermarket wheels are available in 6x139.7 mm; ensure correct lug nut type and seating (conical vs. spherical) for your wheel.
- Variations: rare factory options or conversions can alter bolt pattern; always confirm with the owner’s manual or dealer for exact year/model.
These details help you source wheels and tires with confidence and avoid fitment issues such as interference with brake components or misalignment.
How to verify your exact year and model
To confirm your vehicle’s bolt pattern, use the following steps to verify against your specific year and trim:
- Check the owner's manual, the tire and wheel information placard on the driver’s door jamb, or the GM official spec sheet for your year/model.
- Count lug nuts on the wheel hub (you should see six for Silverado 1500).
- Measure the bolt circle diameter by measuring the distance between two opposite lug holes across the hub center.
- Confirm hub bore size (center bore) to ensure proper centering with aftermarket wheels, typically around 78.1 mm for modern GM trucks.
If you’re unsure, consult a local tire shop or the dealership for a precise confirmation before purchasing wheels.
