FAQ
What is the bolt pattern on a Chevrolet Cobalt?
The Chevrolet Cobalt uses a 4x100 bolt pattern on most variants we cover with a 57.1mm center bore. Other generations use 5x110 / 65.1mm (2005–2006). Always check the exact year and trim before ordering.
What is the Chevrolet Cobalt center bore?
The hub-centric center bore is 57.1 mm on the most common generation; see the table for variants. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Chevrolet Cobalt years share the same wheel fitment?
No. The bolt pattern or center bore changed between generations, so wheels are not interchangeable across all years. Use the year-by-year table on this page to pick the right specification.
Which forged wheels fit the Chevrolet Cobalt?
Any wheel drilled 4x100 with a 57.1mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
