Mercedes-Benz GL450 Spare Tire

The Mercedes-Benz GL450, a premium luxury SUV, does not come with a standard full-size spare tire as most usual vehicles do. Instead, it is equipped with a "run-flat" tire. Run-flat tires are designed to resist the effects of deflation when punctured, allowing the vehicle to continue to be driven at reduced speeds (around 55 mph) and for limited distances, generally between 10 to 50 miles depending on the brand and model of the tire. The main advantage of this type of tire is that it can save the driver from having to change a tire in dangerous or uncomfortable conditions. The exact tire size for a Mercedes GL450 may change based on the specific model year of the vehicle, but a common size seen often is 275/50R20. Always check your vehicle's Owner ' s Manual or consult with a tire professional to confirm the correct tire size for your model.

Mercedes-Benz GL450 models manufactured from 2007 to 2016 have tires with overall diameter ranging from 30.5" to 30.9", 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 GL450 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz GL450 vehicles based on acceptable tire diameter range of 29.6" to 31.8". Some GL450 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Mercedes-Benz GL450 spare tire size designated by vehicle's manufacturer.
