Chain hitting rear tire?

[Charlie98]

Doing some maintenance today on the Monster, I noticed some weird wear on the new Rosso III...

Obviously the chain is hitting the tire... but I'm wondering why?  The shop that put the tire on also adjusted the chain for me, and it still seems to still be in adjustment.  Is the Rosso III just a little wider than the II?  Or am I missing something?

If the chain has 1/2in play side to side it's due for replacement

any pics?
Tyre sizes?
I run a 190 rear and only had issue b/c I did not have it lined up properly.
