Tire upsizing

Curious what would be the largest size tire I can put on my 2018 SL550 I have the stock 19” wheels, they are due to be replaced soon and I would like a little wider tread but don’t want any issues rubbing. Suggestion would be greatly appreciate.

I'm running 305/30/19 on the rear and stock on the front. They are awesome and now the rear tires don't look smaller than the front tires and very aggressive stance from the rear....

Anyone wishing to upsize rear only on their facelift, Non-AMG R231's, and/or using the 14 blade turbine style wheels (see below).

The W223's use a 10"x20" ET48.1 rear wheel. (1st pic) same size (or darn close) as the forged AMG 10 blade wheels. (10x20 ET48 with 285/30ZR20's ) (3rd pic)
I would always double check, but, should be an easy swap, especially as they become more prevalent in the secondary/used marketplace.

Good Luck!

looking at 275/30/19 for the front, doing tire size comparison its just a little smaller in height and .8” wider. Any reason why no one ha up sized the front on the SL?
