2025 Mercedes-Benz AMG GT 63 Spare Tire

The Mercedes-Benz AMG GT 63 does not come equipped with a traditional spare tire. Instead, it features run-flat tires and a tire repair kit for emergency purposes. Run-flat tires are designed to keep the vehicle operational in the event of a puncture, allowing the driver to reach a service station or garage without the need for an immediate tire change. The exact tire size depends on the model year and optional upgrades, but standard tires for an AMG GT 63 are usually front 265/40ZR20 and rear 295/35ZR20. The tire repair kit provided can temporarily seal small punctures in the tread, enabling the vehicle to be driven at reduced speed until professional help can be sought.

2025 Mercedes-Benz AMG GT 63 comes with 5 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 AMG GT 63 spare tire size.
