2018 Cadillac XTS Wheel Fitment Guide — What Works & What to Avoid
Your 2018 Cadillac XTS has a 5x120 bolt pattern and rolls on 18x8.5 wheels with a 45mm offset from the factory. You can upgrade to 19-inch or 20-inch diameters in widths ranging from 8.5 to 9 inches, or stay with 18-inch in sizes between 7.5 and 8.5 inches wide. The vehicle runs a square setup, so front and rear fitments are identical across all trims.
Watch for the 67.1mm hub-centric bore on your XTS—use hub-centric rings if your chosen wheel has a larger bore to ensure a safe, vibration-free fit. Only 5x120 wheels will bolt on properly. Pushing too wide or choosing aggressive negative offsets risks contact with your fenders and suspension components, so stick within the compatible size range we've verified for your model.
Every wheel in our 2018 Cadillac XTS fitment is tested to bolt straight on and ships free to the lower 48 states. You'll find excellent options from Heritage Wheel, Work Wheels, OHM, Aodhan, Petrol, KATANA RACING, Niche 1PC, and Enkei all in stock and ready to ship.
