That tread pattern has me wondering what would be the ptopper orientation for the placement of each of those tires on all four wheels. I mean look at it, the way the sipes on the side with the narrow strip are angled there can only be one direction of installation to get water to leave the tire. And if you want to make it symmetrical so that the narrow strip is on the inside of both sides, or on the outside of both sides, there's no way you could mount that so that water would be leaving the tire properly for all four tires.
It is an asymmetrical tread design, very common nowadays. The direction of rotation doesn't matter, the tire has an inside and an outside.
