Mercedes-Benz GLC300 Spare Tire

The Mercedes-Benz GLC300 does not come equipped with a traditional spare tire. Instead, it includes run-flat tires and a tire fit repair kit, which are designed to continue operating for a certain distance even after a puncture. Run-flat tires can typically carry the vehicle up to 50 miles at a speed of 50mph after being punctured. This gives the driver a chance to reach the nearest service center without having to change the tire immediately. However, if the owner of a GLC300 wishes to carry a spare tire, the typical size they require would be a compact or full-size equivalent to the vehicle's original tire size - 255/45 R20, depending on the vehicle's specific model year and wheel specifications.

Mercedes-Benz GLC300 models manufactured from 2016 to 2025 have tires with overall diameter ranging from 29.1" to 29.2", 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 GLC300 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz GLC300 vehicles based on acceptable tire diameter range of 28.2" to 30.1". Some GLC300 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 GLC300 spare tire size designated by vehicle's manufacturer.
