What is the bolt pattern on a 2010 Chevy Cobalt?
The bolt pattern for a 2010 Chevy Cobalt is 5 lug holes on a 110 mm circle (5x110).
This article explains what that means for wheel compatibility, how to verify the exact specifications for your specific car, and where to find official data. It covers common configurations across the 2010 Cobalt lineup, including base, LT/LS, and SS variants, and notes where trim differences can occur.
Bolt pattern details
Before listing the key specs, here is a quick primer on the terms you’ll encounter when shopping for wheels or tires for the 2010 Cobalt.
- Bolt pattern (bolt circle): 5x110 mm — five lug holes arranged on a 110 mm circle.
- Center bore: 64.1 mm — the hole in the wheel that centers the wheel on the hub when properly mounted.
- Lug nut size and seat: commonly M12x1.5 with a 60-degree conical seat; confirm with your wheel manufacturer or vehicle manual for exact fitment.
- Recommended wheel offset: typically around ET40 to ET49 depending on wheel width and trim; verify with the wheel spec sheet for aftermarket options.
These specifications apply to most 2010 Cobalt models, but always confirm exact figures for your vehicle using official documentation or a dealer Parts diagram.
Hub-centric vs lug-centric considerations
The center bore and whether the wheel is hub-centric or lug-centric can affect fitment and ride quality. The 64.1 mm center bore is designed to align the wheel with the hub surface; using wheels designed for hub-centric mounting helps minimize vibration and ensure proper seating. If a wheel has a larger center bore, a hub-centric ring may be needed to achieve precise alignment.
How to verify the exact spec for your car
To confirm your specific vehicle’s wheel specs, use these steps:
- Check the owner's manual or GM service information for your car’s wheel and lug specifications.
- Look up your VIN on an official parts site or contact a GM dealer to pull the exact fitment data for your trim and production run.
- Inspect your current wheels to count lug holes, measure the bolt circle, and measure the center bore.
If you’re uncertain, consult a qualified tire and wheel shop to verify compatibility and avoid mounting issues or safety risks.
Summary
For a 2010 Chevy Cobalt, the standard wheel bolt pattern is 5x110 with a 64.1 mm center bore. Lug nuts are typically M12x1.5 with a 60-degree seat, and wheel offsets commonly fall in the ET40–ET49 range, though exact figures vary by trim and wheel design.
