Hey guys,

So today I got my pump (Serfas FP-35) in order to inflate the tires in my Globe Work 1 urban bike. The tires are 700x38c (Schrader valve) and the sidewall specifies to be inflated "75-100 psi". I pumped from 40 psi until the gauge marked "100" and then went away to do some chores. A couple of minutes later I hear a horrible deafening explosion, and come back to find my tire flat and the tube inside was ripped. The tire looks perfectly fine, though.

It probably helps to explain that I have never done this before, but what did I do wrong? Did I push the tire pressure too far? Everything on the bike is stock.
