The rears are in the red on the tread gauge on both the outside and the inside. The inside is where the thread is showing though, but either way the tires are done since its red across the entire tread.

Seems like Michelin Super Sports are back ordered in both 295/30/20 and 305/30/20 though, WTF!
So I ordered a pair of Nitto NT05 305/30/20 for my rears. Coming in tomorrow.
