Basically title, this symbol is on the tires of my new (to me) CAAD12. Are the tires on backwards? The right side of the picture is the front of the bike, the left side is the rear. This is the front tire. Another picture below showing which way the tread is facing. The tread "looks" right, it appears it would channel water away from the center correctly.
I'm not aware of any other tire on land that would vary based on being driven or not. Sure, a driven wheel has torque applied to it, but I haven't seen an automobile with an equivalent arrangement. Nor are rail wheels for that matter.
Also, all wheels are braked on a standard bicycle, which would subject them all to the same torque, which should exceed acceleration torque when adjusted properly.
