2009 Pontiac G8 Wheel Fitment Guide — What Works & What to Avoid
Your 2009 Pontiac G8 uses a 5x120 bolt pattern shared across Base, GT, and GXP trims. The factory setup runs 18x8 wheels at 48mm offset. You can step up to 18-inch widths ranging from 7.5 to 9.5 inches, or go 19-inch with either 8 or 10-inch widths. The G8 runs square fitment, so matching offsets front and rear keeps things balanced and predictable.
Keep in mind that only the 5x120 bolt pattern will work on your G8—no other patterns fit. Your hub requires a 67.1mm center bore; use hub-centric rings if a wheel's bore exceeds that size. Pushing too wide or running overly aggressive offsets risks rubbing into the fender and suspension, so stay within the compatible sizes and moderate offset ranges we've verified.
Every wheel we list bolts directly onto your G8 and ships free across the lower 48 states. We stock options from Heritage Wheel, Work Wheels, OHM, Aodhan, Petrol, KATANA RACING, Niche 1PC, and Enkei, so you'll find quality and style to match your build.
