2008 Cadillac STS Base Wheel Fitment Guide — What Works & What to Avoid
Your 2008 Cadillac STS Base requires a 5x115 bolt pattern. The stock setup runs 17x7 with a 49-millimeter offset. You can upgrade to 17x7.5, 17x8, or step up to 18-inch wheels in sizes 18x7.5 through 18x9, or go larger with 19 and 20-inch options, all on the same non-staggered configuration.
Keep in mind that only the 5x115 bolt pattern will fit your STS. The hub is 70.3 millimeters, so if you choose a wheel with a larger center bore, use a hub-centric ring to ensure a proper fit. When selecting wider or more aggressive offsets beyond the factory 49-millimeter spec, verify clearance with your tire choice to avoid rubbing the fender or suspension components.
Every wheel we list for your STS bolts on and ships free throughout the lower 48 states. Stock your garage with options from Heritage Wheel, Petrol, American Racing, Asanti Black, Niche 1PC, and other trusted brands available now.
