I was recently inspecting my tyres and found the flat head of a nail in the rear one. Should I leave it or should I pull it out? I am worried that if I pull it out it will make things worse but it cant be great to leave it in either can it? Its going to bother me every time I get on the bike, you know worried my rear tyre is going to go bang all of a sudden. Any thoughts, experience of similar things or help offered would be great.
