I am confused.

Thanks in advance for any help.
It looks like they are asymmetric and nondirectional, so there is an outside and an inside portion of the tread pattern, but it doesn't matter which direction the tires run. So when looking at the car from behind, the tread pattern on the left and right rear tires will look identical, instead of being mirror images of each other.

It does seem counterintuitive that a tire with diagonal tread block sections could run either direction, but apparently it works. This is the same situation with the Michelin Pilot Sport PS2 and Super Sport, the Pirelli PZero, the Bridgestone RE11, and other performance tires.
