Mercedes-Benz SL550 Spare Tire

The Mercedes-Benz SL550, a luxury grand tourer, does not come with the traditional full-size or temporary 'donut' spare tire directly from the manufacturer. Instead, it utilizes run-flat tires that are designed to resist the effects of deflation when punctured, allowing the driver to continue to a place where the tire can be repaired or replaced safely. However, Mercedes-Benz does provide a 'tire-fit' repair kit, which is a high-end air compressor that one may use to inflate the tires. Still, for those who prefer having a spare tire, they would need to acquire it separately. The spare tire size for the SL550 typically would be 255/40R18 for the front tires and 285/35R18 for rear tires, although this may vary depending on the model year.

Mercedes-Benz SL550 models manufactured from 2007 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 SL550 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz SL550 vehicles based on acceptable tire diameter range of 25.2" to 26.8". Some SL550 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 SL550 spare tire size designated by vehicle's manufacturer.
