Mercedes-Benz SL450 Spare Tire
The Mercedes-Benz SL450, being a luxury sports car, does not come with a traditional full-size spare tire to save on weight and space. Instead, it utilizes a run-flat tire system which allows the vehicle to be driven for a limited distance at a reduced speed even if the tire is completely deflated. This eliminates the need for immediate roadside tire changes in case of a puncture. However, if an SL450 owner prefers to have a spare tire, it would ideally be of the same size as the car's standard size, which is 255/40R18 for the front tires and 285/35R18 for rear tires. It's crucial to note that it might not fit in the car's boot due to space constraints and the presence of a retractable hardtop roof mechanism.
Mercedes-Benz SL450 models manufactured from 2017 to 2020 have tires with overall diameter of 26", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Mercedes-Benz SL450 years and trims.
Listed below are compact spare tire sizes that can fit some Mercedes-Benz SL450 vehicles based on acceptable tire diameter range of 25.2" to 26.8". Some SL450 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Mercedes-Benz SL450 spare tire size designated by vehicle's manufacturer.
