my tire guy called me back today....he recommends either of these tires for the back of the SS.

He said he talked to several people about these tires...said they would give the best grip for the rear...
I’m probably going to try the hancock one....
the toya comes stock on the New 800 hp Jeep. There would have to be a pretty good reason for that.
