The Mercedes-Benz GLS is the flagship three-row Mercedes SUV — think S-Class comfort applied to a full-size SUV platform. It uses air suspension, weighs over 5,000 lbs, and is typically driven by owners who expect the quietest, smoothest tire possible without sacrificing the German precision feel. Staggered fitments on sport packages narrow the tire selection significantly.
Mercedes-Benz GLS tire sizes
The 2020 to present GLS 450 and GLS 580 use 275/50R20 (non-staggered) on the standard 20-inch wheels. Larger wheel packages step up to a staggered fitment: 275/45R21 front / 315/40R21 rear on 21-inch wheels, or 285/45R22 front / 325/40R22 rear on 22-inch wheels. The AMG GLS 63 uses a staggered setup: 275/50R21 front and 315/45R21 rear, with 285/45R22 front / 325/40R22 rear optional.
Earlier GLS (2016 to 2019) used 275/55R19 or 275/50R20 depending on wheel package; larger AMG-appearance wheel packages step up further. Always verify on the driver door sticker — Mercedes trims vary significantly.

Best tires for the AMG GLS 63: staggered 21-inch
Michelin Pilot Sport 4S (275/50R21, 315/45R21) — summer benchmark for the AMG GLS 63. The PS4S is available in both staggered sizes and delivers the maximum performance the AMG drivetrain deserves. Summer only — not for cold weather.
All-season options in the AMG's staggered 21-inch sizes are limited. Many GLS 63 owners run the summer set year-round in mild climates, or keep a dedicated winter set — avoid mixing all-season and summer tires across axles.

Frequently asked
What tire size does the Mercedes GLS use?
GLS 450/580 standard (20-inch): 275/50R20. Larger packages (21-inch): 275/45R21 front, 315/40R21 rear. AMG GLS 63 staggered (21-inch): 275/50R21 front, 315/45R21 rear. Verify on the driver door sticker.
How much do Mercedes GLS tires cost?
275/50R20: $185 to $275 per tire. 275/45R21: $195 to $290 per tire. AMG 63 staggered 21-inch set: $900 to $1,400 for all four installed.
Can I rotate the tires on my GLS?
On a standard GLS with a square (same size front and rear) setup, yes, and regular rotation keeps the set wearing evenly. Performance and larger staggered wheel packages run wider rear tires, which can't be cross-rotated, so the rears wear faster and get replaced sooner. Check whether your fitment is square or staggered before planning a rotation schedule.
Should I replace all four tires on my GLS at once?
On a 4MATIC GLS, replacing all four together is the safe call, since big tread-depth differences can stress the all-wheel-drive system. On a square fitment you can rotate to keep them even and reach that point together. When one tire is damaged early, ask the shop whether matching or replacing in pairs is the better move for your setup.
Where can I get Mercedes GLS tires installed near me in West Georgia?
We match you with trusted independent and luxury-focused shops around Carrollton and the wider West Georgia area for free.
