2025 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.
2025 Mercedes-Benz GLC300 comes with 3 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Mercedes-Benz dealership to confirm the correct 2025 Mercedes-Benz GLC300 spare tire size.
