I was doing tire shopping. It was a little confusing you have to choose between front, front/rear or rear. If you choose either front or rear individually it says size isn't available. If you choose the front/rear option voola that size is available. I ordered that way I was just trying to get a rear tire 120 80 18 and I'm so frustrated because I still don't know if I even ordered a tire at all or two tires or the tire I even wanted to order.
