I ran over a piece of metal today and need to replace 1 rear tire. Does anybody know if the Rosso are directional tire???? I kown most directional tire have arrows on them but these PZoro's don't have anything on them. The reasons I am asking are the letters on both sides of the tire looks different and I've placed an order with tirerack and need to specify right or left if they are directional. Thanks in advance

TIre companies don't manufacture, and you don't order "left" or "right" tires. Directional tires can be flipped to be put on the other side. But once you run them, don't flip them.
