Mercedes-Benz GLS550 Spare Tire

The Mercedes-Benz GLS550 does not typically come with a spare tire as it is equipped with run-flat tires, which are designed to resist the effects of deflation when punctured, allowing the vehicle to continue to be driven at reduced speeds (up to 50mph) for limited distances (approximately 50 miles), depending on the amount of load the vehicle is carrying. However, there is an option to purchase a spare tire separately for added peace of mind. The appropriate size of a spare tire for the GLS550 would depend on the model year, but commonly it's 165/80R18. It's also important to note that the spare tire, regardless of size, should only be used temporarily and replaced by a regular tire as soon as possible, due to its reduced handling characteristics compared to a regular tire. However, always consult your vehicle's owner's manual or a Mercedes-Benz dealer to ensure the correct spare tire size and type are used.

Mercedes-Benz GLS550 models manufactured from 2017 to 2019 have tires with overall diameter of 30.3", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Mercedes-Benz GLS550 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz GLS550 vehicles based on acceptable tire diameter range of 29.4" to 31.2". Some GLS550 models may require the use of a traditional full-size tire as a spare.
