After I had a flat the other day Ive replaced the tube and was going to head out for my ride this morning. I decided (wisely) to check the gash on the outside of the tire. I found it and its pretty big I think. At least a 1/4 inch long and with the tube inflated all the way it makes a little bump and I can stick a pen pretty far into the tire so is this tire done and I need to get a new one or can I still ride this one? I just dont want to have another flat because something got into the old hole, which is open enough I think that it could.
Thanks
