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 265/50R19 on the standard 19-inch wheels. The AMG Line package with 20-inch wheels uses 265/45R20 (non-staggered) or 275/45R20 depending on configuration. The AMG GLS 63 uses a staggered setup: 275/40R21 front and 315/35R21 rear.
Earlier GLS (2016 to 2019) used 275/50R20 on standard and 285/45R21 on AMG packages. Always verify on the driver door sticker — Mercedes trims vary significantly.
Best tires for the GLS 450 and 580 — standard wheels
Continental CrossContact LX25 (265/50R19, 265/45R20) — the quietest all-season for the GLS. 70,000-mile warranty, best-in-class wet traction, very low road noise. Excellent fit for the GLS comfort character.
Michelin Pilot Sport All Season 4 SUV (265/45R20) — for GLS owners who want the sport feel. Available in 265/45R20. Strong sport character with all-season capability.
Bridgestone Dueler H/L Alenza Plus (265/50R19) — OEM-style highway touring for GLS owners who prioritize long wear and quiet. Bridgestone is an OEM supplier to Mercedes-Benz. Outstanding highway refinement.
Best tires for the AMG GLS 63 — staggered 21-inch
Michelin Pilot Sport 4S (275/40R21, 315/35R21) — 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.
Michelin Pilot Sport All Season 4 (275/40R21) — the year-round sport all-season front. Matching the rear in a less common 315 size may require checking availability; some AMG GLS 63 owners run summer rears with all-season fronts.
