2023 Mercedes-Benz AMG GT 63 S Spare Tire
The Mercedes-Benz AMG GT 63 S does not come equipped with a conventional spare tire. Instead, this high-end performance vehicle utilizes run-flat tires, designed to resist complete deflation when punctured, enabling you to continue driving for about 50 miles at a maximum speed of 50mph to reach a safe place or service center. The standard tire size for the AMG GT 63 S is 275/35R21 for the front and 315/30R21 for the rear. Mercedes also provides a Tirefit mobility kit, which is essentially a canister of sealant and an air compressor to fix minor punctures temporarily. However, for more significant tire damage, a full tire replacement would be necessary.
2023 Mercedes-Benz AMG GT 63 S comes with 2 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.
