I purchased this car as a certified pre-owned vehicle from Mercedes Benz in December 2024 with 14,000 miles on the odometer. This vehicle has factory 21-inch AMG rims. Since that time, I have had to replace 5 tires on this vehicle, all from Mercedes Benz dealerships. I purchased an additional $2,000 tire insurance policy from Mercedes Benz due to this recurrent issue. Due to the size of this rim, these tires are extremely prone to blowing and flats. Furthermore, this vehicle ds not come with a spare tire or even with a storage compartment which can accommodate a spare tire. I was under the impression that this is because Mercedes Benz equips these vehicles with run-flat tires, however I recently learned that Mercedes ds not offer run-flat tires on the 21 inch rim, leaving customers with no choice to but have the vehicle towed each time a flat tire occurs. I have been stranded on the side of the road 3 times within the past 3 weeks alone. Other customers have experienced and reported similar issues with this vehicle.
