2009 Cadillac STS Base Wheel Fitment Guide — What Works & What to Avoid
Your 2009 Cadillac STS bolts on a 5x115 pattern and rolls on 17x7 stock wheels with a 49-millimeter offset. You can upgrade to larger 17-inch widths, move up to 18 or 19-inch fitments, or go as large as 20 inches. Since the STS runs the same wheel specs front and rear, any of these sizes work as a square setup across all four corners.
The 5x115 bolt pattern is specific to your STS, so verify fitment before ordering. A hub-centric ring is necessary if your chosen wheel's bore exceeds the vehicle's 70.3-millimeter center bore. Pushing beyond the recommended offset range or selecting overly aggressive widths risks interference with fenders and suspension components, so stick within the compatible sizes listed.
All wheels fitting this vehicle mount securely and ship free throughout the lower 48 states. Heritage Wheel, Petrol, American Racing, and Asanti Black are among the quality brands currently stocked to fit your STS.
