Mercedes-Benz R320 Spare Tire

The Mercedes-Benz R320, a luxury SUV from the renowned German automaker, features a spare tire of a compact size that is meant to be used temporarily in the event of a main tire failure. This NATO (non-usable full-size as original) spare tire, commonly known as a "doughnut" tire, is notably smaller to save space and weight. For an R320 model, the standard spare tire size is often 155/90D18, but it can vary depending on the R320's model year and its original tire size. This spare tire should only be used to make the necessary travel to a repair facility due to its limited speed and durability when compared to a regular tire, highlighting the importance of promptly patching or replacing the damaged main tire.

Mercedes-Benz R320 models manufactured from 2007 to 2009 have tires with overall diameter ranging from 29" to 29.1", 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 R320 years and trims.

Listed below are compact spare tire sizes that can fit some Mercedes-Benz R320 vehicles based on acceptable tire diameter range of 28.1" to 30". Some R320 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 R320 spare tire size designated by vehicle's manufacturer.
