Folks,
Toyo has issued a Consumer Advisory on the RR tires.
The basics of this issue, as they apply to R compound tires generally, is explained here:

Here are some questions I have had answered:
1. Are these recommendations permanent?
-Yes, they are expected to be, though active R&D with regard to this issue is ongoing.
2. Does the drive axle recommendation apply to our low HP cars?
-Yes
3. What happens if my tire starts to show seam separation?
-Contact your dealer to evaluate the tires for warranty replacement.
4. Are we proceeding with the switch to RR's as planned
-Yes
5. Can I still rotate my tires?
Yes, keeping the orientation guidelines in mind. For our cars diagonal rotation (i.e LF to RR, RF to LR) would work.
6. Are all date codes affected?
At this time, that appears to be the case. I don't know of any current production changes, though R&D continues.
