I have a '16 B250 4Matic. considering switching to regular radial tires but what are the choices on spare tires? I've seen on Euro sites factory using 135/80/17 with a 3.5" x17 et19.5 spare wheel. Where can I get one of these here? Also there needs to be a tool kit as well.

any suggestions?

Finally found one that will work. Came off a 2012 C63, size 125/70/18. Takes up a bit of space but worth it.
