Mercedes-Benz SL 550 Spare Tire Sizes
The Mercedes-Benz SL 550 has used a 5x112mm bolt pattern for all models from 2007 to 2020 along with tire diameters ranging from 25.7" to 26.0" 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 the specific Mercedes-Benz SL 550 years and options. In this case, 125/70R19 and 145/70R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
