went out to the garage last night to go on a ride and saw my Falkin rear tire was flat. After laying her over so I could see better, I found a double headed nail in it at an angle. I took if off today and the tire dealer put a patch on the inside, at least there wasn't any plug sticking out (I thought they would just plug it) do you think its safe to ride or should I just replace it? By the way, the tire shop brought it back out cause they couldn't find a leak (I had removed the nail pryer to taking it). I showed them where it was and they took it back in to repair.
