Possible faulty Schrader valve I have a Schrader valve that is leaking air. I have a feeling that I over inflated the tyre. Recommended was 40-65psi and gaugue was showing just over 60. Up until that point it was pumping fine and then air started escaping and now leaks as much air as it takes in. 

Any ideas what the problem might be or what issue I might have caused by over inflating, if I have?
In my experience, when a Schrader valve starts leaking suddenly, the most common reason is that there is a small piece of debris that prevents the valve from closing. The easiest way to remove them is to slightly overinflate the tire, then fully open the valve by pressing the center pin. If this does not help, the valve might be faulty and the tube should be replaced.
