2025 Mercedes-Benz AMG GT 43 Spare Tire
The majority of latter-day Mercedes-Benz vehicles, including the AMG GT 43, do not often come with a traditional spare tire due to considerations for weight reduction and space optimization. Instead, the Mercedes-Benz AMG GT 43 comes with a tire repair kit which includes a tire sealant and a compact electric compressor to inflate the tire. An alternative to this is the use of run-flat tires, which are built to resist the effects of deflation when punctured and can reportedly support the vehicle for distances up to 50 miles at reduced speeds (up to 50 mph), even after a puncture. However, there are also optional factory-installed "Spare Wheel Packages" available which usually include a compact spare wheel, a tire, a jack, and the necessary tools. The provided compact spare tire in such instances would most often be of smaller size compared to the regular ones on the vehicle, but it ' s intended for temporary and emergency use only. It's always recommended to check the owner's manual or consult with the dealership for the accurate tire size and type that best fits your Mercedes-Benz AMG GT 43.
