The 2018 Cadillac ATS Base and its Luxury, Premium Luxury, and Premium Performance counterparts all share the same five-by-one-fifteen bolt pattern. Your ATS comes standard with seventeen-by-eight wheels featuring a forty-eight millimeter offset. Every wheel we offer for your vehicle is verified to bolt on perfectly, and we ship free throughout the lower forty-eight states.
Whether you're upgrading to eighteen, nineteen, or twenty-inch wheels, you'll find quality options from Heritage Wheel, Petrol, American Racing, Performance Replicas, Asanti Black, Niche 1PC, Voxx Replica, and Kraze. Our selection includes multiple widths and offsets designed specifically for your ATS, giving you flexibility to customize your ride without compromise.
2018 Cadillac ATS Base Wheel Fitment Guide — What Works & What to Avoid
Your 2018 Cadillac ATS bolts on a 5x115 pattern and rolls stock on a 17x8 wheel at 48mm offset. You can step up to 18-inch, 19-inch, or 20-inch diameters while keeping the same width or going slightly wider—up to 18x9, 19x9.5, or 20x8 all fit without compromise. Since the ATS runs square (not staggered), any compatible size works equally well front and rear.
The ATS accepts only 5x115 bolt patterns, so verify before ordering. Its 70.3mm hub-centric bore means you'll need hub-centric rings if your chosen wheel has a larger center bore. Stay cautious with aggressive offsets or extra width; pushing too far can invite contact with fenders or suspension components, so stick within our listed compatible sizes.
Every wheel we list for the 2018 ATS Base is confirmed to bolt on and ships free throughout the lower 48 states. Heritage Wheel, Petrol, American Racing, Performance Replicas, Asanti Black, Niche 1PC, Voxx Replica, and Kraze are all in stock and ready to ship.
