2018 Mercedes-Benz GLS550 Wheel Fitment Guide — What Works & What to Avoid
Your 2018 Mercedes-Benz GLS550 4Matic uses a 5x112 bolt pattern with a 66.6mm hub bore. Stock wheels measure 18x8 with a 56mm offset. You can upgrade to larger sizes including 19-inch, 20-inch, or 21-inch wheels in widths ranging from 8 to 10.5 inches, all sharing the same non-staggered setup across the vehicle.
Only wheels with a 5x112 bolt pattern will fit your GLS550. Since many aftermarket wheels have a larger center bore than your 66.6mm hub, hub-centric rings become essential to ensure proper fitment and balance. Aggressive offsets or excessively wide wheels risk contact with fenders and suspension components, so verify clearance when stepping up in size or going lower than stock offset.
Every wheel we list has been verified to fit your 2018 GLS550 and ships free throughout the lower 48 states. Heritage Wheel, Aodhan, Motegi Racing, Work Wheels, Niche 1PC, Petrol, Rotiform 1PC, and MRR all offer options in stock that work perfectly on your Mercedes.
