"PS2s aren't unidirectional and not mirror. Because the sides are marked outside as Randall notes, the tread pattern will be oriented forward on the right and back on the left. When I say oriented, i'm referring to the tread pattern on the outward facing band."
Thanks, I understand which is the outside orientation of the tire but was unsure about them not being mirror-imaged. I wonder how it effects handling to have the tread pattern running in different directions on the left and right sides.
