Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Center-bore records disagree: year-level hub 56.6 mm vs trim range 57.1–65.1 mm. Interchange below does not treat this as an unqualified match.

These are vehicle-year records whose recorded OEM ranges overlap this 2007 Chevrolet Cobalt. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 8 donor years. Listed 8 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Dataset suggestionHub-centric rings ≈ 65.1 → 57.1 mm – not a verified installation requirement.
Hub-centric rings of about 65.1 → 57.1 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. Approximate position vs the mid OEM package: outer change -6.35 mm, inner change -6.35 mm. This uses aggregated width/offset ranges, not a specific wheel.

Hub-centric rings of about 69.1 → 57.1 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. Approximate position vs the mid OEM package: outer change -2.35 mm, inner change -10.35 mm. This uses aggregated width/offset ranges, not a specific wheel.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

The following values are the known OEM specifications available for this model year. Some trims or option packages can differ. If any value on your car does not match, use your door-jamb tire placard, the owner’s manual, or an OEM source with your VIN to confirm, then enter your exact factory setup in the calculator.
| Bolt pattern (studs x PCD) | 4x100 |
| Center bore | 56.6 mm |
| Thread size | M12 x 1.5 |
| Rim diameter | 17 in |
| Rim width | 7.0 in |
| Wheel offset (ET) | 42 mm |
| Backspacing | 5.15 in |
| Tire size | 205/50R17 |
If your 2007 Chevrolet Cobalt left the factory with a different wheel or tire size, that is normal for certain trims. Verify your exact OEM size and specifications before comparing or buying wheels.
The calculator on this page is designed to compare a “Wheels from (donor vehicle)” setup against “Installed on (your vehicle).” It also lets you try a custom wheel and tire size. Follow these steps:
Tip: Keep overall tire diameter close to stock, typically within about 3 percent, to protect ABS, gearing feel, and speedometer accuracy. Always verify brake caliper clearance with the wheel design you plan to use.
Run through this list to avoid returns and safety issues.
Starting from the known OEM reference 17x7 ET42 with 205/50R17, you can explore wider tires, different offsets, or alternative diameters using the calculator. Because some trims vary, treat the following as testing ideas rather than guaranteed fit:
Always validate brake caliper clearance with the exact wheel model. Some designs with aggressive spokes or barrel shapes can contact calipers even when width and offset appear acceptable.
Use safe shop practices and recheck everything after a short shakedown drive.
What is the correct bolt pattern for the 2007 Chevrolet Cobalt?
Our known OEM reference on this page lists 4x100. Some trims can differ. Verify your exact bolt pattern with the door-jamb placard, the owner’s manual, or an OEM source using your VIN before purchasing wheels.
Do I need hub-centric rings?
If your new wheel’s center bore is larger than 56.6 mm, use rings that reduce to 56.6 mm so the wheel centers on the hub. If the new wheel’s bore is smaller than 56.6 mm, it will not fit.
What offset range will fit?
This can vary by trim and brake package. Use the calculator to model your current wheel, then test the new wheel width and offset. Maintain inner clearance to suspension components and control outer poke to avoid fender contact. Physically measure your car for final confirmation.
Can I run spacers or adapters?
Spacers and adapters change offset and can affect bearing load. If you use them, choose hub-centric parts, ensure proper stud engagement or use extended studs, and verify local regulations. Re-check torque after 50 to 100 miles.
What tire sizes will not rub?
There is no single answer for all trims or wheel designs. Keep overall diameter close to stock and use the calculator to check inner and outer clearances. Always test turn-to-lock and drive over bumps to confirm.
What lug nuts should I use?
Match thread size M12 x 1.5 and the seat type required by the wheel (commonly conical or ball). Using the wrong seat type can lead to loosening or damage.
What torque should I use on the lug nuts?
Follow the torque specification in the 2007 Chevrolet Cobalt owner’s manual or an OEM service source. Re-torque after a short drive.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
