Mercedes-Benz R 320 Spare Tire Sizes

The Mercedes-Benz R 320 has used a 5x112mm bolt pattern for all models from 2007 to 2009 along with a tire diameter of 29.0" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for Mercedes-Benz R 320 spare tire selections. In this case, 155/85R18 and 195/55R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
