Chevrolet Cobalt Wheel Specs
2010 Chevrolet Cobalt stores 5 wheel configurations. Rim diameter runs 15–18 in. Offset is 42 mm. Stored bolt patterns: 5×110, 4×100. Vehicle hub bore is 56.6 mm on the year record. Trim center bore is 57.1 / 65.1 mm. These are different source fields.
Figures are stored catalog values. A matching bolt pattern does not prove the wheel clears the brakes or the body.

Questions
What wheel sizes does the Chevrolet Cobalt use?
Chevrolet Cobalt in 2010 stores rim diameters of 15 in, 16 in, 17 in, and 18 in, with widths of 6 in, 7 in, and 7.5 in. 5 configurations are listed below. These are catalog rows, not a single universal size.
What is the Chevrolet Cobalt bolt pattern?
Stored bolt patterns in 2010 are 5×110 and 4×100. Select the configuration that matches the vehicle.
What offset range is stored for the Chevrolet Cobalt?
Stored offset in 2010 is 42 mm. Offset is the distance from the rim centerline to the mounting face. A positive value places the face toward the outside of the wheel.
What is the Chevrolet Cobalt center bore?
The year hub record is 56.6 mm (auto_model_year.center_bore_id → rim_center_bore). Trim center bore is 57.1 mm / 65.1 mm (zdonor_wheel_size_trim.center_bore). The two fields do not match, so both are shown.
Does Chevrolet Cobalt wheel size vary by year?
Wheel rows are stored for 6 years, from 2005 through 2010. This page shows the 2010 rows. Choose another year to see that year's diameters. Years are not collapsed into one size.
What does wheel offset mean?
Offset is how far the mounting face sits from the rim centerline, in millimeters. It is not the same number as backspacing. Backspacing on this page is calculated from rim width and offset because the rim table does not store backspacing.
What is the difference between positive and negative offset?
Positive offset moves the mounting face toward the street side, which tucks the wheel inward relative to a zero offset. Negative offset moves the face toward the brake side, which pushes the wheel outward. The stored values on this page are the catalog offsets, not a recommendation to change them.
Can I use wheels with a different bolt pattern?
A different bolt pattern does not mount on 5×110 studs. An adapter is a separate part that converts one pattern to another. This page can look up adapter products after you choose a target pattern. It does not decide that an adapter is safe for this vehicle.
When are hub-centric rings needed?
A hub-centric ring fills the gap when the wheel's center bore is larger than the vehicle hub. The stored vehicle hub in 2010 is 56.6 mm. A ring is not required when the bores match, and a ring cannot make a smaller wheel bore fit a larger hub.
How do I determine the required hub-ring size?
Use the vehicle hub bore of 56.6 mm and the center bore printed on the aftermarket wheel. The ring size is the wheel bore minus the hub bore. This page does not copy the hub bore into the wheel-bore field.
How does changing wheel width affect fitment?
Adding width grows the wheel on both sides of the centerline. The offset calculator estimates how far the inner and outer lips move. That estimate does not establish brake, suspension, or fender clearance.
How does offset affect wheel position?
Lowering the offset number moves the wheel outward. Raising it moves the wheel inward. The calculator on this page uses the standard width-and-offset geometry and labels the result as a position change, not a fitment verdict.
What should I verify before buying aftermarket wheels for a Chevrolet Cobalt?
Confirm bolt pattern, center bore, thread, offset, and load rating on the wheel you are buying. Brake clearance, suspension clearance, and body clearance are not stored in this catalog, so a matching bolt pattern is not proof the wheel fits.
Can I install wider wheels on a Chevrolet Cobalt?
Stored widths in 2010 are 6 in, 7 in, and 7.5 in. A wider wheel can be compared with the offset calculator. The catalog does not say whether a wider wheel clears the brakes or the fender.
What is the difference between wheel bore and vehicle hub bore?
Vehicle hub bore is the diameter of the hub that the wheel centers on, taken from the model-year rim_center_bore record. Wheel center bore is the hole in the wheel. On this page the trim center bore comes from zdonor_wheel_size_trim.center_bore. When those numbers differ, both stay visible.
